Greenhouse Vegetable Fertilization Reasonable Selection of Fertilizer
In the fertilization of vegetables, nitrogen, phosphorus and potassium compound fertilizers, diammonium phosphate, urea, ammonium bicarbonate, potassium sulfate, and fertilization are generally used; vegetable compound fertilizers and organic-inorganic compound fertilizers are actively selected. In order to enhance the activities of beneficial microorganisms in the rhizosphere of crops, improve soil physical and chemical properties, and adjust crop nutritional balance, we recommend the use of supplementary fertilizers such as amino acids, humic acids, bio-organic compound fertilizers, and microbial fertilizers, such as rhizobia and phosphorus bacteria. Fertilizer, compound microbial fertilizer and so on. At the same time, we encourage the use of slow/controlled fertilizers with added nitrification inhibitors to prevent leaching and volatilization of chemical fertilizers. Remind farmers to avoid using chlorine-containing fertilizers (such as ammonium chloride) or nitrate nitrogen fertilizers (such as ammonium nitrate).
