Problems solved by technology

Heavy metal pollution not only leads to the decline of soil fertility, but also may cause the heavy metal content of agricultural products to exceed national standards, endangering the health of humans and animals, seriously affecting environmental quality and sustainable economic development
On the other hand, most of the compound fertilizer series products on the market rarely meet the biodegradable standard, which not only increases the burden on the soil, but also has a certain impact on crops

Abstract

The invention relates to a stable long-acting compound fertilizer which comprises the following components in parts by weight: 50-130 parts of coated urea, 10-25 parts of calcium superphosphate, 5-20parts of ammonium chloride, 7-25 parts of potassium chloride, 10-30 parts of sweet potato type citric acid residue, 6-30 parts of vinasse, 3-18 parts of EDTA chelated zinc, 4-20 parts of amino acid chelated iron, 10-25 parts of plant growth regulator, 5-18 parts of urease inhibitor and 6-28 parts of an anti-caking agent. The compound fertilizer disclosed by the invention can meet the requirement of crops on nutrition, is reasonable in proportioning, slowly releases nutrients, improves the utilization rate of the fertilizer, promotes the crops to absorb nutrition, enhances the stress resistanceof the crops and reduces soil hardening and environmental pollution caused by fertilizer loss.

Description

technical field [0001] The invention belongs to the field of agricultural fertilizers, in particular to a stable long-acting compound fertilizer and a preparation method thereof. Background technique [0002] my country's economy has developed rapidly in recent decades, but it has also brought about very serious problems. On the one hand, the discharge of three wastes and the unreasonable application of fertilizers, pesticides, fertilizers, etc. have made the farmland polluted by heavy metals account for an increasing proportion of the total cultivated land in the country. Heavy metal pollution not only leads to the decline of soil fertility, but also may cause the heavy metal content of agricultural products to exceed national standards, endangering the health of humans and animals, and seriously affecting environmental quality and sustainable economic development. On the other hand, most of the compound fertilizer series products on the market rarely meet the biodegradati...
