Leafy vegetables are mainly edible stems and leaves, such as cabbage, amaranth, Ganlan, spinach, celery and leek and other vegetables, foliar fertilizer is generally urea, ammonium sulfate and other water-soluble available fertilizer, urea concentration of 2 %, ammonium sulfate concentration of 0.3%, spray 60 kg -80 kg per acre, spraying two or three times during the whole growth period is appropriate. Can also spray 0.3-0.5% per acre 50 grams of rice vinegar solution -60 kg. For melons and solanaceous vegetables such as eggplant, pepper, tomato, zucchini, cucumber, beans, cowpea, and kidney bean, etc., the fertilizer on the leaf surface is mainly composed of NPK fertilizer or multiple compound fertilizers, such as 0.3% potassium dihydrogen phosphate. , 1% of urea + 2% of superphosphate (leaching solution) + 0.5% of potassium sulfate solution, 0.08% of rare earth fertilizer solution, foliar treasure, photosynthetic micro fertilizer, ammonium molybdate and so on. Generally sprayed two or three times during the whole growth period, spray 40 kg -50 kg per 667 square meters. Spraying compounded multi-element fertilizer on fruits and vegetables is more effective, such as spraying sugar nitrogen solution (0.2% urea, 0.3% potassium dihydrogen phosphate, 1% sucrose). Spraying compounded fertilizer not only can increase the yield, but also can significantly increase the disease resistance of the plant and reduce the damage of vegetables such as downy mildew. Bulbs, root vegetables, yam vegetables, bulbs, root vegetables, such as onion, garlic, radish, carrots, potatoes and taro and other vegetables, foliar fertilizers are generally dominated by phosphate fertilizers and potassium fertilizers, such as 0.3% phosphoric acid II. Potassium hydrogen solution, superphosphate, and ash leaching solution. Root vegetables can be sprayed with 0.2% borax solution, which can effectively prevent the occurrence of physiological diseases. The spraying of 0.1% zinc sulfate + 0.2% ammonium molybdate solution on potato significantly affected tuber enlargement and quality.
