Abstract

The invention discloses a special high-fertilize-efficiency composite coated fertilizer for wheat. The special high-fertilize-efficiency composite coated fertilizer is characterized by being prepared from the following raw materials in parts by weight: 12-14 parts of bentonite, 9-11 parts of gypsum powder, 25-28 parts of urea, 11-14 parts of methyl acrylate, 1-2 parts of manganese sulfate, 1-2 parts of zinc oxide, 1-2 parts of ammonium molybdate, 1-2 parts of sodium borate, 8-12 parts of plant ash, 29-33 parts of diammonium phosphate, 18-21 parts of potassium sulfate, 7-9 parts of a soil improver and a proper amount of water. The special high-fertilize-efficiency composite coated fertilizer is sufficient in nutrient and balanced in nutrition, not only contains basic nitrogen, phosphorus and potassium fertilizers, but also contains multiple trace elements and mineral components, and alleviates the soil caking situation while the growth requirements of wheat are met; due to addition of the soil improver, the fertilizer has the functions that the effect is improved and plants are promoted to absorb nutrition; due to adoption of a coating process, the fertilizer is very good in slow release function, high in fertilizer efficiency and long-lasting in fertilizer property.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a compound-coated fertilizer special for wheat with strong fertilizer efficiency and a preparation method thereof. Background technique [0002] Coated fertilizers are also called coated fertilizers and film fertilizers. Fertilizers made of quick-acting fertilizer granules wrapped with semi-permeable or impermeable film substances. Film-forming substances include plastics, resins, paraffin, polyethylene and elemental sulfur. The purpose of the coating is to slowly release the quick-acting nutrients in the coated fertilizer after it is applied to the soil, so as to prolong the fertilizer effect. The release rate depends on the type of coating, thickness, particle size, fertilizer solubility, soil temperature, soil water content, and soil microbial activity. It is suitable for crops with high economic value, long growth period, large amount of fertilizer but inconvenient to fertilize ...
