Pumpkin is rich in pumpkin seed alkali, amino acids, vitamins, calcium and other mineral elements, its high nutritional value. At the same time, pumpkin has a very high medicinal value, has a unique curative effect on diabetes, but also has anti-cancer, anti-constipation, prevention and treatment of atherosclerosis and other effects, as well as a good weight loss, the market prospect is broad. 1. Preparation before planting The planting of pumpkins should be based on topography and dryness, convenient irrigation and drainage, and a deep, loose and fertile plot of soil. The production environment complies with NY5010. Should choose to adapt to varieties, strong resistance, high quality and high yield, good commercial, adapt to market demand varieties. The soil requirements for pumpkins are not strict, and sandy loam, clay loam, and loam can all be planted. However, in order to obtain high and stable yields, sandy loam and loam with rich organic matter, deep soil layer are the most suitable. Pumpkin is a bogey continuous crop, should implement rotation. In continuous cropping areas, special attention should be paid to the occurrence of diseases such as seed and soil disinfection and the prevention of diseases such as blight in the production process. 2. Soil fertigation Due to the rainy season in spring, ridges and trenches are required to be deep trenches. In order to facilitate drainage and irrigation, “climb-style†plants can be used. About 10 days before planting, soil preparation was done. About 300kg of organic fertilizer and 30kg of ternary compound fertilizer were applied per acre. Deep-turning was 30cm, and the rake was finely screeded to a size of 80cm and 150cm. The small pod was used as a planting worm for planting pumpkins. As a climber. 3. Sowing Seed soaked in 55 °C water for 10 to 15 minutes, soaking while stirring, stop stirring when the water temperature drops to 37 °C. Soak in water at 20°C for 8 hours. After washing, dry the seed surface with clear water and germinate at a constant temperature of 30°C. Pay attention to ventilation. Wait until about 75% of the seeds germinate before sowing. Generally use greenhouse seedlings, suitable sowing time should be based on the weather conditions in the year, seedling age 20 to 30 days, when the two leaves are planted. During sowing, special attention should be paid to the seeds lying flat in the nutrient bowl with a thickness of about 1 cm. Planting density is 2.5~3m spacing, plant spacing 0.5m, double plant 0.8m, planting 500 plants per acre. 4. Field management 4.1 Fertilizer Water Management Pumpkin is resistant to drought and drought and requires less water during the growth period. After the root squash is in place, the watering of the seedlings can begin. Should be combined with water once fertilizer, depending on seedling growth, can be applied urea 7kg per mu. Stretch vines strictly control the water, generally do not topdressing fertilizer, timely drainage after rain. 4.2 Pruning The mandibles are double-vine pruned. When the melon shoots grow to 5-6 true leaves, they are picked up. Two strong lateral vines are selected from the base, and the rest of the lateral vines and lateral vines are removed from the base. Guaman 0.5 ~ 0.6m began to vine, after every 0.4m pressure, a total of pressure 2 ~ 3 times. 4.3 artificial pollination In order to improve the fruit set rate, artificial pollination should be supplemented. In case of rainy days, artificial pollination must be performed. In the morning from 8 to 10 o'clock, male flower heads with pollen are used to contact the female stigma. 4.4 Guaranteeing fruit preservation In order to improve the commercial quality of the product, each 2-3 fruit of the squash should be selected, and 5 to 10 nodes of female flowers should be selected, and 4 to 6 fruits per plant. The remaining female flowers or young fruits should be removed in time. 4.5 Fruit Protection After the rapid expansion of the young melon, the melon pad, such as the melon was born in the low-lying Department, can be moved to a high place along the melon, so as to avoid excessive humidity and rotten melon, pumpkin light is too strong late growth, melon surface prone to sunburn Disease needs to be shaded with grass or melon leaves. 4.6 Disease prevention and control Implement the plant protection policy of "prevention as the mainstay and comprehensive prevention and control", and create an environmental condition conducive to growth and development by selecting resistant varieties, nurturing strong seedlings, strengthening cultivation and management, scientific fertilizing, and improving and optimizing the ecological system of vegetable fields. . Yellow traps were set to kill aphids and black light traps were used to trap pests. Actively protect and use natural enemies to prevent pests and diseases. China Agricultural Network uses biological pesticides to control pests and diseases. For chemical control, 70% thiophanate-methyl wettable powder can be used, with a dosage of 90 g per mu, to prevent diseases such as blight, wilt disease, anthrax, blight, disease, and powdery mildew. Aphids and thrips can be treated with 10% imidacloprid at a dose of 1.5 g per mu. 5. Harvest Early melons are good for picking tender and tender melons, which can make the newly grown young melons have sufficient nutrition to promote growth, and tender melons are suitable for harvesting after 10-15 days of flowering.
