First, the application of base fertilizer high-yield watermelon field generally per 667 square meters (1 mu) need to apply organic fertilizer 3000 ~ 5000 kg, 75-100 kg of superphosphate, 7 kg of urea, 5 kg of potassium sulfate. It is advisable to apply the ditch, and the fertilizer can also be applied to the melon ditch or the melon, and then turned into the soil.
Second, skillfully apply seedling fertilizer In the seedling stage of watermelon, there must be enough quick-acting fertilizer in the soil to ensure the normal growth of seedlings. In general, a part of the fertilizer has been applied to the base fertilizer, as long as there is no symptoms of deficiency in the seedling stage. Can not topdress. If there are fewer fertilizers applied in the base fertilizer, or those that are not equipped with chemical fertilizers and melon fields that show symptoms of lack of fertilizer, the amount of seedlings should be chased in order to promote the normal growth and development of the seedlings. The fertilization time should be before and after the seedlings grow to 4-5 true leaves, or 3 to 5 kg of urea and 10 kg of superphosphate per 667 square meters (1 mu) before pouring the seedling water.
Third, the foot chasing after the extension of the mango watermelon melon vines, should be applied to promote the vine before the vine water, generally 667 square meters of ternary compound fertilizer 20-25 kg, can also be applied for 15 kg or so Diammonium phosphate to promote elongation of stems.
Fourth, discretion to sit on the melon fertilizer Watermelon flowering before and after sitting on the melon, is a key period of sitting melon, in order to ensure that watermelon plants can sit on the melon, generally do not top dress. However, when the young melon grows to the size of the duck egg, the watermelon enters the peak of the absorption. In this period, if the lack of fertilizer not only affects the expansion of the melon, but also causes the later de-fertilization, the plant premature aging, which not only reduces the yield of watermelon, but also affects the quality of the melon. Therefore, it is necessary to apply the melon fertilizer, generally 8 to 10 kg of urea per 667 square meters (1 mu), 70 to 80 kg of superphosphate, 30 to 40 kg of potassium sulfate, or 667 square meters of ternary compound fertilizer 40 In kilograms, the fertilization amount of high-yield melon fields can also be increased appropriately.
Fifth, the late sprayable surface fertilizer After the watermelon is expanded into the late maturity stage, the root's ability to absorb fertilizer has been significantly weakened. To compensate for the lack of roots and to ensure the normal maturity and quality of watermelon, foliar spray fertilizer can be applied. For example, every 667 square meters can be sprayed with 0.3% urea solution, or a mixture of 0.3% urea and 0.2% potassium dihydrogen phosphate 50-75 kg. In this period, it is suitable to spray 0.06% to 0. 08% rare earth solution can increase the sugar content of watermelon by 0.6%~1.7%; or spray 667 square meters in watermelon expansion period, 200 grams of borax, 2400 grams of sucrose, 0.7 grams of calcium chloride, water The solution of 50 kg is 50-100 kg, which can generally be sweetened by 1 to 2 degrees, and the yield is increased by 10% to 20%. 
The practice of watermelon production shows that for every 100 kilograms of watermelon produced, about 0.19 kg of nitrogen, 0.092 kg of phosphorus, and 0.136 kg of potassium are needed. In general, a sufficient amount of nitrogen fertilizer is the basis for high yield of watermelon. Adequate phosphate fertilizer can promote the growth and development of plants, promote flower bud differentiation, make it flower early, sit early and mature early, and potassium is a catalyst for various enzymes in plants, which can promote photosynthesis, protein synthesis and sugar increase. Improve the quality of melons. However, the following points can be grasped when applying specific fertilizers.
