Western melon has a short growing period and relatively low production costs. Compared with grain and oil crops, its comparative benefits are still obvious. Now it is spring season for seedling cultivation and sowing of melon, how can farmers scientifically grow melon? To this end, the reporter interviewed Yan Congsheng, associate researcher of the Institute of Horticulture of the Provincial Academy of Agricultural Sciences.
Choose the variety. In recent years, small watermelons have become increasingly popular among urban consumers. Yan Congsheng told reporters that their early-growing small watermelons, represented by Xiuli, Lilan, and Yilan, were well recognized by the market. Taking Xiuli as an example, the weight of a single melon is only 2 to 2.5 kilograms, and it belongs to a very early maturing variety. On the seedling cultivation of western melon, the suitable sowing period of western melon in spring is from mid to late December to late March. The specific sowing time is determined by the facility conditions.
Apply a good base fertilizer. Farmers should choose fertile soil, convenient drainage and irrigation, and loose soil plots. 1500-2000 kg of organic fertilizer, 100 kg of cake fertilizer and 50 kg of ternary compound fertilizer are applied per acre. The reporter learned that if farmers adopt the double-vine pruning and climbing cultivation method, it is appropriate to plant 700-800 plants per acre; if the hanging-vine cultivation and single-vine pruning method are used, it is appropriate to plant 1300-1400 trees per acre; for semi-hanging vines As far as cultivation is concerned, it is advisable to plant 1,000-1100 plants per acre; it is advisable to plant 300-400 plants for grafted sparse planting. In terms of plant adjustment, 6-7 leaves can be used for topping, and 3-4 vines are pruned. The watermelon flowers are retained in the second to third females, and the melon is retained in 8-10 nodes. Farmers can produce multiple crops of melon.
Prevent diseases and insects. The common diseases and insect pests of western melon are fusarium wilt, blight, anthracnose, aphid, etc. Farmers should give priority to agricultural control, physical control and biological control, and use chemical control reasonably. Melon farmers can use 4% pyrimidine nucleotide antibiotics in water for 600 times or 10% mixed amino acid copper solution to dilute 220-330 times to irrigate roots or drenched stems. Pyridox 22.5% suspending agent 40-50 g / mu with water spray or benzoxanthin 325 g / liter suspending agent 30-50 g / mu with water spray; Anthracnose can be treated with 10% water Dispersed granules 50-75 g / mu with water spray or mancozeb 80% wettable powder 170-250 g / mu with water spray; for control of aphids, thiamethoxam 25% water-dispersed granules 10 g / mu with water spray.
