It is often heard that melon farmers complain about the lack of watermelon knots, delays in the market, low yields, and low sweetness issues. The reasons for the above-mentioned phenomenon are mostly related to fertilization and improper management. First, no basal fertilizer and topdressing organic fertilizer are applied; second, partial application of nitrogenous fertilizer; third, excessive use of base fertilizer and top dressing; fourth, basal fertilizer application is too small, and melon seedlings grow weak; Fifth, there is no time to squash over watermelon; It is improper to select the part of melon on the melon vine. To this end, we should focus on grasping relevant technologies based on fertilizer and pruning. First, science and fertilizer control water. 1, change the single fertilizer application of organic and inorganic fertilizers combined. Organic fertilizer is a delayed fertilizer, but rich in nutrients, water, fertilizer, fertilizer for a long time, inorganic fertilizer, although faster, but the short duration, the combination of the two can avoid weaknesses. In particular, the application of organic fertilizers and multiple compound fertilizers is more effective. 2. Switch to traditional organic fertilizers as high-energy organic fertilizers. Such as enzyme bio-organic compound fertilizer, yeast with organic fertilizer, Hui Manfeng organic compound fertilizer. These fertilizers have many advantages. They can not only improve the soil, inhibit soil-borne diseases, but also increase the yield of watermelon, improve the quality, and increase the sweetness. 3. Change conventional fertilization to optimize fertilization. One should look at the earth and see fertilization, application of organic fertilizer in particular to emphasize the sensation, lyrical good fertilizer effect to play soon, after the lack of lyrical water should be applied, so that the water to ridicule, with water to regulate fat. The second should be changed to spread fertilization material for the ditch or Shixue. Three should reasonably arrange the bottom and top dressing ratio. With mulching cultivation, the ratio of bottom and top dressing is 7:3 or 6:4, and the ratio of bottom and top dressing is 5:5. In order to increase the sweetness, Hui Man Fung or Zhuang Fu Xing active liquid fertilizer can also be sprayed, 100 kg per mu water 50 kg, after the flowering of watermelon to the young fruit during the expansion of spraying twice. In the adjustment of moisture, the top dressing is generally controlled one week before the opening of the female flowers. Second, pressure vines topping heart. 1, in the melon vine growth point front with fine soil suppression, in order to slow the development of melon vines. 2, to pay attention to the fruit before and after the fruit section 2 should not be crushed, to prevent damage to young fruit. 3, after the occurrence of female flowers in the fruit section, leave 5~7 leaves at the front of the fruit section to stop the melon vine growth. Third, do a good job of disaster management. 1, in the case of little rainfall, before the rain can be set on the opening of male and female flowers on plastic bags, artificial pollination after the rain. 2. Artificial pollination can also be conducted when there are few insects. 3, in the wind before the wind, using the branches of the tree into a card inserted into the soil stuck melon. 4, when the hot weather comes, can be covered in the larvae of the larvae to prevent chew.
