Second, melons and vegetables. Such as pepper, eggplant, tomato, beans and various melons, the need for NPK is relatively balanced, should use NPK mixed solution or compound fertilizer. Spray 1%-2% urea with 0.3%-0.4% potassium dihydrogen phosphate or 2% compound fertilizer solution. It is usually sprayed 1-2 times in the early and late stages of growth. Spraying in the later stage can prevent premature aging, enhance stamina, and have a good yield increase effect.
Third, root vegetables. For example, garlic, onion, radish, potato, etc. require more phosphorus and potassium, and foliar fertilizer can use 0.3% potassium dihydrogen phosphate solution and 10% grass ash leaching solution. Generally, it is sprayed 3-4 times per season, and the effect is better.
Spraying foliar fertilizer is best when the afternoon sun is not too strong on cloudy or sunny days. According to the growth of vegetables, 30-50 kg per acre of spray liquid is used to limit the frying of the foliar fertilizer. According to the demand for trace elements in different vegetables, the appropriate amount of micro-fertilizer can be applied to increase the yield and improve the quality, saving labor and efficiency, but avoiding acid-base neutralization.
