fashion jewelry bangles wholesale The cultivation of watermelon cultivation in small arch sheds is now introduced as an example: the structure and performance of the small arch shed
The small arch shed should choose to go north to south, covering 1.4-1.6 meters wide. 40 cm deep melon grooves, after fertilization, mix soil fertilizer and make 60 cm wide, 10-15 cm high turtle -shaped back -shaped cultivation bed, each side of the bed forms a 30 -cm waters, each side of the groove Make a 20 cm height 20 cm wide puppet, and insert 1 1-1.2 meters of bamboo slices of 2 meters long, 4 cm wide every 1-1.2 meters, forming an arch of about 1.5 meters wide and about 0.7 meters high. Deducting 2 meters wide thin film, pressed by soil pressure, the shed spacing is about 1 meter. Bamboo pieces per mu 240-260 pieces. 0.014 mm agricultural membranes are about 7.5 kg or 0.03 mm agricultural membranes are about 16 kg, and 0.005 mm membrane is about 2.5 kg. The minimum temperature at the beginning of the year of the structure can be stabilized at 5 degrees in early April, which can meet the requirements of the watermelon slow seedlings. At present, the cultivation of grafting seedlings mostly use simple greenhouses with heating facilities to cultivate grafting seedlings, use pumpkin or gourd as rootstocks, and adopt a leaning or penetration method. At about 40 days of seedlings, the seedbed is set up to the north and south of the seedbed, 1.2 meters wide from east to west, and requires a flat bottom. The width width is 30-40 cm, and the height is 15-20 cm. And the diseased bacteria eggs. Generally, 2 parts of fertile pastoral soil plus 1 part of high-temperature fermentation of high-temperature fermentation and rotten organic fertilizer, and then add 0.5 kg of dilate or 1 kg of compound fertilizer according to each cubic meter, 50%multi-bacterial spirit 3-4 two, 3-4 two, 3-4 two, 3-4 two, 3-4 two, and 3-4 two. 50%phosphorus 1 phosphorus is 1 two. After fully mixing, load it into a nutritious bowl with a diameter of 8 cm high. Put the water through the water through the nutrition bowl 1 week before the broadcast, 2 kg of sulfur powder/mu of the greenhouse before the greenhouse disinfection, 0.2 kg/mu of the enemy dichlorvos for 24 hours. The seed germination rate at that time was only about 40%. You need to break the dormant with gibberee. The specific method is to soak the seeds with warm water for 1-2 hours, wash the debris, and then soak it with 150-200 ppm. If the seeds are used in the previous year, the seeds can be soaked directly. The soaking time can be 12 hours. The gourd seeds are thick and difficult to absorb water. It can be treated with hot water perm, soak with cold water without seeds, and then pour the hot water from 80-90 degrees to continuously stir in one direction to reduce the water temperature to 70-75 degrees and keep it for about 1 minute. Finally, pour cold water to make the water temperature. Decrease to 20-30 degrees, continue to soak seeds for 24-36 hours, you can also use 100 ppm gibbererin treatment by referring to the pumpkin seed treatment method. Watermelon seed treatment: one is to soak planting with 50%multi -bacterial or todbin 500 times liquid for 30 minutes for 30 minutes. After removing and cleaning, soak in warm water for 6-8 hours; the other is to cast with 80-90 degrees hot water for 3-5 seconds, then add cold water to reduce the water temperature to about 55 degrees, soak the seeds for about 10 minutes, reduce to 20-20-- 30 degrees for 6-8 hours. Sowing: Use pumpkin as rootstock. Pumpkin seeds are soaked in germination. After germination of watermelon seeds, two capsules are sowed in the nutrient bowl at the same time in the nutrition bowl and the spike seeds were sown each. The temperature of the day is 30-35 degrees, and at 18-22 degrees at night, ensuring soil temperature above 18 degrees, after the seedlings fall to about 25 degrees during the day, and 15 to 16 degrees at night. You can sow the watermelon seeds after germination. Watermelon seeds are sown in the sand table. Before sowing, soak the sand with boiling water. After cooling, sprinkle the watermelon seeds about 1 cm and sow, cover the soil for 1 cm, and the cover film moisturizes and increases. The seedlings of the sand table for about 5-6 days of the greenhouse are about 5-6 days. During the grafting period, grafting: Pumpkin and watermelon are connected: Pumpkin seed Ye Ping shows up the growth point when the heart is exposed. At 0.5-1 centimeters under the child, the blade is cut down at 45 degrees angle, and the depth is 2/5- In 1/2, the incision is about 1 cm long. At the same time, the corresponding part of the watermelon scion is obliquely cut upwards, and the depth is 1/2-2/3 of the neck thickness. The length of the incision is the same as that of the rootstock incision. The scion incision is embedded in the incision of the rootstock's stem, so that the interface of the two is closely fitted together, and the fixed interface is fixed with grafting. After about seven days, the interface healed, cut off the root of the scion, and removed the grafting clamp after 10-15 days. Use the gourd as an anterono-wood roof: remove the gourd top buds and true leaves when grafting, leave only two pieces of leaf, and then use a bamboo stick with 6-8 mm slopes with a sharp tip of the watermelon seedlings. The gourd leaf veins and the gourd stem about 45 degrees are inserted, and the tip of the bamboo stick is just exposed. Put the watermelon seedlings at 8-10 millimeters under the cotyledon, cut the stems with a blade, the length of the cut surface is 8-10 mm, and the bamboo sticks are pulled out quickly and inserted the watermelon scion into the gourd rootstock. The scion -leaf crosses the shape of "ten". Management after grafting: After grafting, cover the small arched sheds to moisturize in time, and cover it with a shade net or analog. The first three days generally do not ventilate, 25-28 degrees during the day, 20-22 degrees at night, not less than 18 degrees. The relative humidity of the air in the small arched shed remains more than 95%. After three days, the ventilation gas is gradually increased and the shading time is shortened. After about 12 days of grafting seedlings, the temperature can be reduced to 24-26 degrees during the day and 16-18 degrees at night. Pay attention to the germinated side buds of the rootstock in time. Spray drugs to prevent diseases. Low -temperature refining seedlings 3-5 days before planting, increased the amount of wind during the day, 22-24 degrees during the day, and fell to 13-15 degrees at night to enhance the adaptability of seedlings to the environment in the small arch shed after planting. Preparation before planting 1. Fundamental fertilizer: combined with farming and flipping each acre for fermented chicken manure 2-2.5 square or high -quality circle manure 6-8 square (conditional households are best mixed with chicken manure and circle manure in summer Fermentation, more organic fertilizer with high temperature fermentation is not easy to burn seedlings), 30-40 kg of dibil ammonium, 30-40 kg of potassium sulfate, 10-15 kg of urea or 25-40 kg of ammonium carbide Dedicated or sprayed respectively. In the late March, the sun, the ground, and the buckle sheds were selected in the late March to make a timely requiring. 7-10 days before the planting, the ground film, the buckle small arched shed, baked land, and heated. Planting, planting period: Shi City and surrounding counties and cities are generally at the end of March and early April. When 5 cm temperature in the small arch shed stabilizes more than 12 degrees, you can choose to plant without wind and sunny. Popular trees fall, plant density: each cultivation bed is planted in two lines, the plant spacing is not less than 0.7 meters, and 650-700 plants are planted per mu. During the planting, the acupuncturer or melon shovel is perforated on the lid on the lid's membrane and planting the seedlings. Finally, the membrane holes are tightly sealed with soil to cover the small arched sheds in time.
Pylon management 1. Temperature management: Planting — Tuanshu is from planting to melon seedlings 5-6 leaves from upright growth to the period before the growth of creeping, about 13-15 days. The first three days after planting generally do not let go of the wind to promote seedlings. After slowing the seedlings, we can gradually increase the amount of air release every day to 2 pm to achieve cooling, humidifying, improving the conditions of light, reducing the growth rate of plants, improving the resistance of anti -inverse, and reaching thickness of the leaves, neck thickness, and strong root system. Tuanshu -Big Gua: At this stage, it has entered late April, and the evening cream has passed. Generally, freezing damage is needed. The root system and stems and leaves of this period grow rapidly, which is easy to grow. Therefore, the wind should be enlarged in the morning and noon, and the fascinating membranes are used to promote the reasonable distribution of nutrients at night. Early fruits. Generally, the whole method of pruning is used. When the main vine grows to 30 cm long, and the branches of the stem base reaches 5 cm, each plant is selected. Leave two strong side vines with uniform growth, remove the excess side vines early. Generally, the second or third female flowers of the main vine are selected. When the main vines can't sit still, they can choose to sit on the side of the vine. Generally, the extra side branches before the fruit saving position are removed early, and the side branches of several sections after the fruits can leave 3 to 6 leaves to tip to increase the leaf area and increase yield. When it is about 50 cm in length, it can be used in conjunction with 5 kg of urea per acre and 10 kg of potassium dihydrogen phosphate. When the young fruit grows as long as the eggs, it is rushed into 15 kg of urea per acre with water and 20 kg of potassium dihydrogen phosphate. The fruit bowl mouth is 10 kilograms per acre in the size of the bowl mouth, and 15 kg of potassium dihydrogen phosphate can be sprayed with leaf surface fertilizer to prevent premature stems and leaves. Remove the petals that are open on the day and gently apply the pollen on the blooming female flowers. In the operation, pay attention to it to be thorough and uniform to prevent the appearance of deformed fruits. There are two methods and key technologies for the secondary result of watermelon: one is to cut the vines. Three new vines. After the first stubble, the old vines are cut 30 cm from the root of the roots, and the new vines are used. The other is the new shoots, that is, in the late stage of fruit growth, the new vine fruits from the top of the main and side vines are used. Generally, it can be blooming and sitting fruit for 7-10 days. This method is simple, but the fruit is high, the fruit shape is small, and the output is low. The key technology is mainly to do a good job of preventing disease in the first stage of the melon melon, leaf surface spray fertilizer, strictly prevent premature aging of the stems and leaves, clean the countryside in time after picking melon, pour roots with root roots and pursue pursuit of watering, and promote the healthy growth of the new man. Small gift watermelon cultivation technology I. The cultivation season is highly adaptable, and the temperature can grow normally above 14 ° C. Different cultivation techniques can be sown from mid -January to late July, and can be harvested in May to October. Early spring protection land cultivation: Sowing seedlings in mid -late February, 35-40 days of seedlings, seedlings are used to raise seedlings, and it is planted in the greenhouse in mid -April and was listed in early June. Naked land cultivation in spring: sowing from late March to late May, about 30 days of seedling. The protection of seedlings, planted in naked land or covering small arched sheds after the final cream. Summer protection place is delayed: sowing in late July, about 20 days of seedling. In early September, the shed film was covered, and the heating grass curtain was covered in the early days, and it was listed around October. 2. Preparation of sowing nutritional soil: There are many ways to prepare nutritional soil. Commonly used 2/3 grass carbon soil plus 1/3 of the field soil with no melon mix well, or 1/3 of the rotten farmhouse fertilizer plus 2/3 field soil soil Essence Each soil plus 2 kg of calcium phosphate, disinfected with 800 times the bacterial liquid, or fumigated with formaldehyde. Soaking seeds to urge buds: It can be sterilized with 55 ° C warm water and continuously stirred until the temperature of the water drops to about 30 ° C. After soaking for 4 hours, clean the seeds, and then use a wet woolen wrap to tighten the germination in the environment of about 30 ° C. Sowing: The day before sowing, the 800 -fold methylobujin fluid was used to pour the seedlings. When the seed buds grow to about 0.5 cm, sowing in the seedling plate should be placed flat, the sprouts are upward, and the top -covered nutrient soil should be covered with fine nutrient soil. 1.5 cm thick, and pour the seedlings with 800 times nailobobadin solution, and keep the temperature at 25-30 ° C to ensure that the seedlings are neat. The temperature is kept at 18-28 ° C after the seedlings. Do not wet the seedbed. Early spring should prevent frost damage and ensure sufficient light. In summer, the seedlings should be prevented from high temperature. Third, field management planting: Generally, multi -vines and fruit and vines are cultivated, with a row distance of 60-80 cm × 180-200 cm, and 530-730 plants can be planted per acre. It can also be cultivated with a standing grid, with a row distance of 50 cm × 100-140 cm, and double -row planting. Fertilizer: mainly based on bottom fertilizer, supplemented by topdressing. The bottom fertilizer should be composed of 53-66 kg compound fertilizer and 2670 kg per mu. In the future, the entire fertility period is mainly "two water and two fertilizers", that is, vine fertilizer. After one week of planting, nitrogen fertilizer is mainly used for irrigation; melon fertilizers are mainly used for phosphorus and potassium after one week. Remove fruit: small cause and effect, to reach higher yield, you should use multiple vines and fruit cultivation. Generally, a main vine and 3-4 vines are retained, or the vines are not rectified. The rest can be retained with two stubble melons. Prevention and treatment of pests: Small watermelon varieties have strong disease resistance compared to large watermelon varieties. Generally, diseases are vine blight, withered disease, viral diseases, anthracnose, etc. The best prevention and treatment of diseases and insect pests is best performed once every 7-10 days. Watermelon harvesting high -yield cultivation technology has been cultivated in the greenhouse with multiple harvesting technology to cultivate watermelon. It can be harvested 5 to 6 times from May to the end of October, with an average of 7,500 kg of watermelon per mu. The varieties are selected from early ripening, disease resistance, low temperature resistance, and strong early watermelon varieties such as early goodness. The cultivation of Zhuangmiao Nanjing area is generally sown in mid -January, and the nutritional bowl of the electric heatingbed hotbed is used. In the greenhouse, it is 1 meter -wide and 25 cm deep seedlings. The length depends on the number of seedlings. The inner paving film, sprinkled fine soil, straw and other objects, laid electric heating wires on it, and discharged nutritional bowls. Sowing the germination to 80%of the seeds is sown, and 1 capsule is broadcast per bowl. After sowing, it covers 0.5 to 1 cm thick, covering the ground, and a small arched shed. Cover the grass curtains on the small arched shed at night. The temperature of the bed was kept at 30 to 32 ° C during the day, and the night was maintained at 20-25 ° C. 70%of the melon seedlings were removed after the land was unearthed. After Qi Miao, the small arched sheds were properly opened to cool down. Gradually cool down the seedlings 1 week before transplanting. The appropriate period of planting is 2,500 kg of rotten organic fertilizer per acre, 100 kg of rotten cake fertilizer, 10 kg of urea, 50 kg of overlapping calcium phosphate, 15 kg of potassium sulfate, or 100 kilograms of compound fertilizer per mu with potassium sulfate. Combined with fertilization, 3%phosphorus particle particles and 50%multi -bacterial wettable powder are 2 kg per acre. One month before the planting, the whole land was made, and the 5 -meter -wide greenhouse was made of 2 畦, 2 meters wide, and 30 cm wide operating groove in the middle. From late February to March, it is selected to be planted in the morning in the morning. Each row is planted, the plant spacing is 80 cm, and about 330 plants are planted per acre. After planting, water the water, cover the ground after the water seeps, a small arch shed on it, and cover the grasshopper on the small arched shed at night. The management within 10 days after the temperature and humidity management is mainly thermal insulation. The temperature of the shed temperature during the day is maintained at 25-32 ° C, the night is maintained at 18-20 ° C, and the shed temperature exceeds 35 ° C appropriately ventilated and cools down. Increase the ventilation volume appropriately after sitting melon. The temperature of the melon expansion and mature period is kept at 25-32 ° C during the day, and the night is maintained at 15-20 ° C. The small arched shed was withdrawn in mid -April. After the temperature rises in May, pay attention to ventilation and gas, and open the skirt and top membrane to cool down at noon. Remove the edge film in summer and leave the top membrane and replenish water. In August, the temperature was high, and the amount of plant transpiration was large, and moisture and temperature should be scientifically controlled. After transplanting fertilizer and water management, the seedlings are applied to the seedling fertilizer for one week, mainly nitrogen fertilizer. When the melon eggs are large, the rotten acquaintance urine is 600 kg or 10 kg of urea, 10 kg of three yuan high -efficiency compound fertilizer, and 10 kg of potassium sulfate. After each harvest, potassium sulfate and urea are 10 kg or 45%high -efficiency compound fertilizer each. The watermelon watermelon should not be irrigated too much, and the irrigation should be rational according to the tenderness of the leaf color. The plant adjustment adopts the three vines. When the main vine is 60 cm long, two strong side vines are selected at 3 to 5 knots, and all the remaining sides are removed to reduce nutrient consumption. After the melon is steadily removed, the weak branches, sick branches and old leaves, and sick leaves are removed to facilitate ventilation and light transmission. Choose the soil to press the vines in a sunny afternoon. Flower and fruit manages melon eggs in the size of 1 or 2 melons for each plant. When the melon diameter is 12 cm, remove the deformity and excess melon, leaving an average of 1 melon per plant, and 330 melons per acre. Turn the melon once 15 to 20 days after sitting melon, and use dry straw or fruit pad. When the first batch of melon 7-8 matures, the second batch of melons are selected on the new hair vines. The amount of melon is determined according to the long potential of the melon. The temperature in autumn is high, and the salary should be properly pushed back. Generally, 2 melons are selected after 20 knots. The third and fourth batch of melons should be properly removed to ensure the quality of melon. Pay attention to the prevention and treatment of watermelon swelling, rising disease, withered disease, leaf blight, frostmo, anthracnose, white powder and aphids, red spiders and other diseases and insect pests. The first batch of melons will be harvested 37 to 40 days after the female flowers are opened in a timely manner, and they will be harvested once every 30 days. When the first stubble melon is picked, the two stubble melons have been sitting melon. Be careful not to pull the vine too much.

jewelry distributors wholesale on harry hines Planting time: Early ripe watermelon sowing in mid-mid-March last year, medium-cooked watermelon sowing from April to June, and after autumn, watermelon was sown in mid-to-late July.
In after the sowing, the nutrition bowl is watering through the water. When sowing, the bud tip seeds are flattened in the nutrition bowl, 1 capsule per bowl, 1 cm thick, and covering a film.
The expansion information:
1. Watermelon (scientific name: citrullus lanatus (thunb.) matsum. et nakai) One year of vines; stubborn stems, branches, obvious edges. The roll must be thicker, with short pour hair, thick petiole, and densely pilot; leaves paper, outline triangular ovate, white -green, two masks short hard hair, and the heart shape of the blade base. The male and female. Female and male flowers are single in leaf axillary. The male flower stalks are 3-4 cm long and are densely piloted by yellow brown; the calyxic tube is wide; the corolla is pale yellow; Female flowers: calyx and corolla are the same as the male; The fruit is large, nearly spherical or oval, fleshy, juicy, smooth peel, color and decoration. Most of the seeds, ovate, black, red, smooth on both sides, blunt at the base, usually arched on the edges, and summer in the flower and fruit period.
2. There are many varieties of cultivation throughout China, and there are various types of fruit, pulp and seeds. It is the most famous in Xinjiang, Lanzhou, Gansu, Texas, Shandong, and Dongtai, Jiangsu. Its original species may come from Africa. It has been widely cultivated in the world's tropical to temperate, and it has been introduced to China in gold and Yuanshi.
3. Watermelon is the fruit of summer. The flesh taste is sweet and can cool down the summer; the seeds are oil -containing, which can be used as a recreational food; the peel medicine has the effects of clearing heat, diuretic, and lowering blood pressure.
