Abstract

The invention discloses a microelement-rich compound coated fertilizer for crops and a preparation method of the compound coated fertilizer. The compound coated fertilizer is characterized by being prepared from the following raw materials in parts by weight: 26-30 parts of urea, 16-23 parts of ammonium nitrate, 10-13 parts of a calcium magnesium phosphate fertilizer, 3-5 parts of magnesium sulfate, 1-2 parts of zinc sulfate, 2-3 parts of chelate iron, 1-2 parts of sodium molybdate, 1-2 parts of ammonium molybdate, 2-3 parts of copper oxide, 34-36 parts of yellow phosphorus slag, 8-10 parts of an soil improver and a proper amount of water. According to the compound coated fertilizer, the base calcium magnesium phosphate fertilizer is fused with fertilizers of microelements such as magnesium, zinc, iron and molybdenum, so that the stress resistance of the crops is improved, the metabolism of the crops is promoted, and the yield of the crops is increased; the coated fertilizer has a certain slow-release effect, the fertility is slowly released, and the fertilizer is neutral, has an improvement effect on alkaline soil and cannot cause soil hardening.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a compound coated fertilizer for crops rich in trace elements and a preparation method thereof. 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, with the continuous increase in yield levels, crops' needs for trace elements will also increase accordingly. Therefore, micronutrient fertilizers must be supplemented for crop gro...
