Winter cultivation of pumpkin field cultivation

1. Site preparation: Flatten the land and trim it into specifications of 1.2m in width, 04m in ditch, and 80cm in height. According to the planting distance of 1.5m, the average planting capacity is 278 per mu. Seedlings should be transplanted with soil to protect the root system. After transplanting, rooting water should be poured.

2. Cultivation and management during growth period: After the seedlings are colonized, pay attention to fertilizer and water management. For early stage fertilization, more application of thin application can be made. Compound fertilizer can be applied once every 7 days, with a dosage of 5 kg per acre, and in conjunction with the spraying of plant dynamics 2003 foliar fertilizer 1000 times to promote plant growth.

3, flowering results during the cultivation and management: pay attention to water and fertilizer supply during flowering and fruit setting, flowering period should be assisted artificial pollination, improve fruit set rate, pollination should be carried out after the sunny morning morning after sunrise temperature rise. After the young fruit is settled, the whole vine is picked up and bagged. The main cultivars and 2-3 lateral spreads were selected for each plant. Select the correct shape, fruit without pests and fruits, 1 for each fruit, leaving the top 5-6 leaves topping, and the remaining side should be removed. Every 4-5 guava press soil once to prevent running vines and promote adventitious roots. The fruit grows to the size of the egg and is bagged. The plastic foam net is used to set the fruit first, and then the white perforated nylon film bag is put on to prevent the vine burrs from puncturing the rind and raising the fruit with the grass to improve the appearance of the fruit. Before the bagging, a complete sterilization treatment should be performed, and 38% of Dasheng WP or 12% of green butternut EC can be used for spraying to ensure that the fruit does not have spots. The fruit is picked up once every 10 days during the growth period to promote uniform coloring of the whole fruit. All the above work needs to be done in the sunny afternoon. During the period of fruit growth and expansion, fertilizer and water management should be strengthened. Dry fertilizer can be applied once to open the hole. Apply 50kg of compound fertilizer and 25kg of peanut bran per acre. Open the hole and apply it near the plants and vines, cover the soil after fertilization, and pour water. Promote root absorption. Every 7 days, 0.2% potassium dihydrogen phosphate can be used to add 800 times compound amino acid potassium for foliar dressing to promote fruit growth.

4. Pest control: Diseases mainly include seedling damping-off, wilt disease, and powdery mildew. The damping-off disease can be planted with plant ash or 70% Antecan wettable powder 15g sand mixed with 10kg sand. Fusarium wilt can be used 70% Antai or 70% methyl mop WP plus 75% alcohol into a paste to spread the base of the stem, can also be formulated into a 800 times aqueous solution spray control. Powdery mildew can be sprayed with 25% Baileyton WP 1000 times. Insect pests mainly include whitefly and leafminer, which can be controlled by 1.8% abamectin 300 times and 90% trichlorfon crystal 1000 times.

5. Harvesting: After the fruit grows to 1.5-2.5kg, the cucurbit stalk begins to appear cracks. The fruit is evenly colored. After the fruit is hard and has a waxy layer, the fruit ripening can be harvested. Picking can be done in sunny afternoons and guillotines of 3-5 cm length are kept. After the Guati incision is air-dried, it is tightly sealed with wax and carefully handled during the handling process to ensure that the fruit is not injured, which can extend the storage period and reduce nutrient consumption.
