Legume crops such as cucumber, gourd, cayenne pepper, green beans, etc., are all typical potassium-loving crops. Increasing potash fertilizer plays an important role in improving yield and improving quality. In addition, the proportion of calcium absorbed by melons is relatively large, so the foliar spray of calcium fertilizer has a certain effect of increasing production. Through the visits to the main producing areas of southern melons, Jin Zhengda's senior agronomist combined with the company's fertilizer to give a complete set of melon and legume crops scientific fertilization program for farmers to learn from:
Basal fertilizer: mainly organic fertilizer, with the use of high-quality compound fertilizer such as 15-15-15S, 17-17-17S. Kim Jung-sa controlled-release fertilizers such as 18-9-18, 18-8-16 can also be used.
Melon topdressing: top dressing 7-10 times during the whole growth period, chase 1 round of fertilizer every 7-10 days in the result period, top dressing with nitrocarbohydrate 21-6-13, 15-5-20 and sulfur base fertilizer 18-5 -28,16-6-24 and so on.
Beans top-dressing: chase 1 fertilizer at seedling stage, apply fertilizer 2 times during flowering and scab, apply about 20 kg of nitro-aerobic fertilizer each time, and apply it to a planter, acupuncture or spreading. Top dressings are Jin Zhengda's nitro-fertilizers 21-6-13, 15-5-20 and sulfur-based fertilizers such as 18-5-25 and 16-6-24.
