First, choose the precocious, high-yield and disease-resistant varieties of sugar Wang Baoyu, the best sugar Wang Baoyu, Qin Bo No. 1, Qin Bo No. 2, East Asia Fuyu.
Second, nursery technology
1. Select the seedbed, sunny leeward, leveling seedbed surface, cover shed insulation.
2. Seed treatment. Melon seeds were soaked with 800-fold liquid for 15 minutes, washed and washed twice with water, then immersed in warm water for 3 to 6 hours, then rinsed with a damp cloth and placed at a temperature of 25 to 30°C for germination. The buds can be budded in 24 hours, and the sprouting buds should be placed at a temperature of about 10°C.
3. Nutrition soil preparation. Before sowing, prepare nutrient soil, 3 soil manure (best for chickens, sheep and manure), 5 for field soil, 2 for humus, and 1 bag for special fertilizer for Zhuang root and Zhuang root. Breed them evenly and sifted together. Then use 600 times liquid to destroy the killer and 500 times liquid to kill the soil for disinfection, combined with humidity, the nutrient soil into hand to make a group, landing to disperse is appropriate. Stir together for 10 to 24 hours to eliminate pathogenic bacteria and eggs in the nutrient soil. Then start loading nutritious soil. Each nutrient bowl is full, compacted, and then evenly placed on the ground of the seedbed, to be evenly placed, tightly, and then soaked with water to wait for sowing.
4. Sow. Seed sowing in the sunny morning, in the middle of nutrition pods sowing a hole, each nutrient pods put a germination of melon seeds, then cover 1 cm thick disinfectant nutrient soil, cover the mulch, cover the shed, cover the greenhouse insulation.
5. Seedbed management. After sowing, do not let go of the wind before emergence. When the melon seedlings are 70% out of the seedlings, they must first remove the mulch. When the temperature in the shed exceeds 30°C, it is necessary to exhale. Open the leeward place in the shed, ventilation, temperature and humidity, greenhouse temperature can not exceed 30 °C, keep at 18 °C or more at night, if the temperature is relatively low, we must take cold insulation measures to avoid freezing bad seedlings, sowing 10 days after the use of prevention Falling disease seedlings are sprayed 2 or 3 times every 2 to 3 days to prevent the occurrence of damping-off. Ten days before transplanting, seedlings were used to prevent the emergence of blight before and after transplanting. When melons grow 3 to 4 true leaves, they are transplanted.
Third, planting technology
1. Soil preparation. Combined with site preparation, 5000 kg of farmyard fertilizer is applied per acre, and 1 bottle of special fertilizer is used to prevent the wilt of vegetables and vegetables from Shi Erkang. 2 bags of special fertilizer for West melon and vegetables are produced by Shi Er Zhuang, and 20-25 kilograms of East Asia land and old compound fertilizer. Mix thoroughly.
2. Planting time. The general colonization time is at the end of April and early May, and it is best to plant double-membrane melons.
3. Planting methods. Plant spacing 36 to 45 cm, spacing 54 cm, about 3500 per mu, in the planting points in combination with water poured out 1200 times liquid killer, to prevent the occurrence of blight. After planting, the membrane is covered and the arch shed is buckled.
Fourth, field management
1. Shelter temperature management. Do not let out wind in the first five days after planting, mainly to increase ground temperature to promote melon seedling rooting, planting new leaves for 5 to 10 days to grow, marking the entry into the growth stage, the greenhouse temperature exceeds 30°C for air release, lift the membrane in the shelter lee When the wind falls, it is necessary to cover the shed below 28°C in the afternoon and the average weather reaches 18°C ​​to stop covering the shed.
2. Take heart and promote vines. When the melon pod grows to 4 true leaves, it will be picked up to promote the growth of the vines. When three vines grow, if the vines have vines, after sitting in the melons, the first 4 leaves of the melon will be picked and promoted. Grow. If the vine vines don't pick up the melon when they are in the third leaf, they can promote the vines and sit in the melons. Sun Man sits in the melon and picks up the first 3 or 4 leaves in the melon. It mainly promotes melon expansion and early maturing to avoid the loss of water and nutrients. , Each plant has 3 to 4 melons.
3. Top dressing. When melons sit on melons, topdressing begins, which promotes rapid melon growth, increases sugar content, and increases yield. The foliar spray was applied with 800 times solution of Nongfu or East Asia Xiongwei foliar fertilizer, and sprayed once every 7 days for two sprays.
4. Control pests and diseases. It is mainly used to control fusarium wilt and irrigated with 1200 times liquid in the early stage of disease. In the early stages of locust occurrence, insecticides were killed 1000 times. If powdery mildew occurs, use 100 bacteria kill 800 times solution and Nongfu Fu East Asia Xiongwei foliar fertilizer. Spray once every 5 days, the best effect.
5. Timing harvesting timely. Stop watering the previous week to prevent cracking melons. Thin-skinned melons turn white and green to yellow and have aromas. Can be harvested. If it is too mature, it will affect melon production and storage. If you have a nine-score, you must pick and go to the market. Do not wait for the full-fledged to go on the market. This will affect the benefits. Because there are precocious measures and early-maturing varieties, you should pick one and take advantage of it. One of the criteria for melon ripening is flowering for 25 to 28 days. The second is that melons turn green from white to yellow and begin to ripen. If it is too mature, it will affect the quality and yield of melon.
