Teach you the correct cultivation techniques of winter gourd covered with plastic film

(1) Cultivate disease-free seedlings: select Guangdong white gourd with high yield, disease resistance and good commodity quality, and raise seedlings in sunny beds in early April, with seedling age of about 40~50 days. The seedling temperature should be controlled at 25~30℃ in the day and 16~18℃ in the night, and the seedling should be cooled in the later stage. Watering should master the principle of seeing dry, and water should be properly controlled in the middle and late stages to prevent excessive growth of seedlings. Topdressing can be combined with foliar fertilizer for aphid control according to the growth of fine seedlings.

(II) Cultivation techniques: 5000 kg of decomposed manure, 40 kg of calcium superphosphate and 15 kg of diammonium phosphate are applied per mu in combination with soil preparation in the middle of May. 1/3 of them are sown, and the other 2/3 are concentrated in furrow when the row spacing is 80 cm, and the ridge height is 20 cm. After covering the plastic film, planting on the ridge according to the plant spacing of 40 cm, planting about 2500 seedlings per mu. 3 days after planting, irrigate seedling slowing water once, and irrigate seedling urging water again when shooting. After root melon stabilizes, water should be started, watering every 5~7 days, watering amount should not be too large each time, generally filling furrow is appropriate. After planting, quick-acting nitrogen fertilizer was applied once to promote rapid growth of seedlings, and compound fertilizer was applied once after winter melon was seated and in rapid expansion stage. After the melon seedling shoots, it should be inserted into the tripod immediately, and the vine can be tied around the frame. Combine the vines and beat off the lateral branches and tendrils in time. Wax gourd set after stability in time to tip, in order to promote rapid expansion of fruit. Remove the root melon in time, select the second or third melon with positive melon shape, and stabilize the melon in the sunny afternoon after the melon seat is stable.
