A kind of chelated trace element fertilizer

Abstract

The invention discloses a chelating-state trace element fertilizer which is characterized in that the fertilizer is prepared by mixing ammoniated calcium nitrate, borax, compound sodium nitrophenolate, (NH4)6Mo7O24.4H2O, CuSO4.5H2O, ZnSO4.7H2O, MnSO4.3H2O, MgSO4.7H2O, SiO2 and probiotic colony, and the mixed trace element fertilizer comprises the following trace elements in percent by weight based on the pure content: 4-6 percent of boron, 1-2 percent of sodium, 4-5 percent of molybdenum, 4-5 percent of copper, 5-8 percent of zinc, 3-4 percent of manganese, 4-5 percent of magnesium, 5-6 percent of silicon and 3-5 percent of probiotic colony. According to the fertilizer, absorption of nitrogen phosphorus and potassium and other main fertilizers in crops can be promoted, absorption of the trace elements in the crops also can be promoted, the growth of the crops is promoted, and the yield of the crops is improved.

Description

technical field [0001] The invention relates to a plant trace element supplement, in particular to a chelated trace element fertilizer. Background technique [0002] There are many types of fertilizers used for crops, flower seedlings and other crops on the existing market, but long-term application of nitrogen, phosphorus and potassium-based fertilizers to plants will cause soil compaction, water loss or evaporation, resulting in most of the fertilizers Fertilizers cannot be absorbed by plants and become dead fertilizers. At the same time, major fertilizers such as nitrogen, phosphorus, and potassium will cause the lack of trace elements needed by plants due to perennial use. Low-yield soils are prone to lack of trace elements; high-yield soils, as the yield level continues to increase, the crop's demand for trace elements will also increase accordingly. Therefore, micronutrient fertilizers must be supplemented for crop growth. The amount of microelement fertilizers should...

AI Technical Summary

Problems solved by technology

Trace element fertilizers are applied to crops and flower seedlings together with main fertilizers such as nitrogen, phosphorus, and potassium. Under different levels of nitrogen, phosphorus, and potassium, the absorption of trace elements by crops is also different. Trace element fertilizers promote the absorption of main fertilizers such as nitrogen, phosphorus, and potassium. The absorption of nitric acid is also different, and the trace element fertilizers currently available on the market cannot effectively promote the absorption of main fertilizers such as nitrogen, phosphorus, and potassium by crops. At the same time, the absorption effect of crops on trace elements is not good, and cannot effectively promote plant growth.
