1. Reapply base fertilizer. General Mushi fire soil 1500 kilograms, human manure 1000 kilograms, potassium sulfate 10 kilograms, urea 10 kilograms, superphosphate 30 kilograms, imported melon special fertilizer 25 kilograms, pay attention to fertilizer can not be rooted, must use soil to melon root and fertilizer open.
2. Reasonable pruning. In general, 450 to 500 plants are planted per acre, and one main side double vine pruning method is used. The first pruning starts from 40 to 50 centimeters in length and every 3 to 5 days thereafter. After the first melon is stable, it is generally not necessary to prune.
3. Strictly control the position of sitting melons. Seedless watermelon sitting too low or too high can lead to melons, deformity, and low yield. It is generally best to choose the third female flower of the main vine or the second female flower of the lateral vine. Using artificial pollination, only one melon is left in a single plant. If the fertilizer is sufficient, leave two plants per plant, one for the main vine and one for the side vines.
4. Apply swelling melon fertilizer. Adequate water and fertilizer is an important part of the rapid expansion of seedless watermelon. When there are more than 80% of the vines on the vines, when sitting on melons, 50 kg of dried tortilla cakes and 40 kg of ammonium bicarbonate are planted per acre, and 1,500 kg of human excrement can be recovered. The melons cultivated in this way are large, round, sweet, and have a high commodity rate.
