From early spring to early summer last year, many local muskmelon productions suffered long-term low temperature and rainy weather. In some places, planting area was reduced due to dead seedlings; in some places, the growth process after seedling was slow; in some mature periods, heavy rainfall caused no harvest. Or reduce income; Some sweetness is not enough, the quality is not ideal. In order to make up for the shortage of thick-skinned muskmelon production in the spring, the needs of the cultivation market in late autumn can be adopted. Late autumn cultivation is often referred to as anti-season production. Its climate is characterized by high temperature during the seedling period, less rain in the middle period, lower temperature, and lower temperature in the later period. Melon's fertility characteristics are rapid growth at seedling stage, short seedling age, easy to grow long, late fruit development, late maturity. At the same time, there are more pests and diseases. Therefore, we must grasp the following aspects in cultivation techniques. First, choose the best sowing date. The use of Elisabeth and Nettle melons can generally be planted from late June to early August. July is more appropriate. Within the scope of this sowing date, it can meet the demand of melon for accumulated temperature. Second, fine seedlings. Generally, a small arch nursery is used to sow the seed with the bud soaked in the nutrient bowl, one for each grain, and covers 1.5-2.0 cm fine soil after sowing. One foot full of seedbed water, until the seedling grows to 1 leaf 1 heart or 2 leaves 1 heart when transplanting Dingmiao. In order to nurture strong seedlings, we must cover plastic sheds and shade nets on sunny sheds, clear shade nets, and rain cover membranes. Second, we must use small-water sprinkler irrigation when flooding is not sufficient, and must not be flooded. See sunlight sooner or later, to avoid leggy; Fourth, to spray fertilizer before the seedlings are transplanted, such as urea, potassium dihydrogen phosphate or Huimanfeng liquid fertilizer. Third, soil preparation and fertilization. Before the harvest, it is necessary to prepare the soil in time, and plant the sorghum trunk in double rows, and plant the sorghum trunk in a single row. The double cab is 2 meters wide and the single cab is 1.5 meters wide. Advocate one foot under the fertilizer, per acre applied maturity of organic fertilizer 3000-4000 kg, with multiple application of compound fertilizer 30 kg. To prevent leggy, sitting in front of the melon generally do not chase after nitrogen fertilizer, after sitting melon topdressing urea 15-20 kg, potassium fertilizer 10-20 kg. Fourth, rational colonization. Cover black or silver mulch on the entire sorghum before colonization. The planting density per mu is 1500-1800 strains. Generally single vine pruning, 1-2 melons per plant, in the young melon settled immediately after removal of the top heart, in order to promote fruit enlargement, premature. Fifth, Daejeon Management. After planting melon seedlings, as most of the former greenhouses are used, management should focus on shading, temperature control, temperature control, water saving, and fertilizer supplementation, and scientific management. One is the use of shading nets for shade in midsummer, and the light transmittance is controlled at about 50%. Second, the temperature of the film on both sides of the greenhouse is rolled up and the gap between midday and midnight is widened. The larger the contrast is, the better the quality of the squash is. Water-saving temperature control, generally in the extension period of vines poured water, sit 2-3 times watering melon period, avoid flooding irrigation; Fourth, after sitting melon combined with water fertilization, to take acupuncture points or open ditch irrigation facilities. Sixth, early prevention of pests. One is to kill the locusts before moving in large quantities, the second is to focus on preventing viral diseases, and the third is to prevent larvae and blight. Seven, choose to pick melons. In order to improve the quality of melon products, one should not hurry to pick up immature melons; the other is to put back the melons for 3-5 days until they are ready for ripening.
