Abstract

The invention discloses a two-chelating compound fertilizer, which is composed of chelates, potash fertilizer, urea and clay, and also can be joined with monoammonium phosphate based on needs. The two-chelating compound fertilizer of the invention has rational compatibility, simple process, low cost, high efficiency, good particle strength and balanced nutrients, which improves the soil and stimulates the development of plant roots to prevent disease in the process of crop growth due to lack of trace elements; the two-chelating compound fertilizer adds trace elements to the soil and has good organic matter effects, which is a novel efficient compound fertilizer.

Description

technical field [0001] The invention belongs to the technical field of compound fertilizers and relates to a double chelate compound fertilizer. Background technique [0002] The elements needed for crop growth are not limited to nitrogen, phosphorus, and potassium. Simply using a large amount of nitrogen, phosphorus, and potassium cannot achieve the highest yield and good quality of crops. Scientific fertilization and balanced fertilization are important means to improve crop yield and quality. In recent years, with the extensive use of nitrogen, phosphorus and potassium compound fertilizers, the supplementation of medium and trace elements has been neglected. Therefore, the recent large-scale application of large-scale elemental compound fertilizers cannot further increase the yield of crops. On the contrary, crop diseases and insect pests continue to appear, and land and water sources are seriously polluted. The compound fertilizer of prior art is mainly formed by compo...
