Problems solved by technology

However, at present, the domestic supply is mainly inorganic fertilizers such as nitrogen, phosphorus, and potassium. Long-term use of inorganic fertilizers will damage the soil aggregate structure, easily cause soil compaction, and soil hardening. As a result, the more chemical fertilizers are used, the more the output is. low grotesque

Abstract

The invention relates to a slow-release type blended fertilizer. The blended fertilizer is prepared from, by weight, 5 -25 parts of monoammonium phosphate, 7-35 parts of potassium sulfate, 20-70 partsof coated urea, 6-20 parts of borax, 1-10 parts of amino acid chelated zinc, 2-19 parts of humic acid, 10-20 parts of an anti-blocking agent, 2-18 parts of attapulgite, 3-11 parts of straw, 2-15 parts of soybean meal, 2-12 parts of distillers' grains, 3-17 parts of a biological agent and 2-14 parts of a plant growth regulator. The fertilizer can effectively improve the physical and chemical properties of soil, adjust the pH value of the soil, promote the activity of soil microorganisms, increase the activity of soil enzymes, loosen the soil, effectively prevent soil hardening, desertificationand environmental pollution caused by excessive inorganic fertilizers applied to the soil, and improve the yield and quality of crops.

Description

Technical field [0001] The invention belongs to the technical field of crop compound fertilizers, in particular a slow-release blended fertilizer. Background technique [0002] With the continuous development of our modern agricultural construction, there is an increasing demand for high-quality and high-efficiency fertilizers that can increase production and income, and can achieve environmental protection. However, at present, the main domestic supply of inorganic fertilizers such as nitrogen, phosphorus, and potassium, long-term use of inorganic fertilizers will destroy the structure of soil aggregates, which will easily cause soil compaction and hardening of the soil. As a result, the more chemical fertilizers are used, the more and more chemical fertilizers are used. Low grotesque. Therefore, blended fertilizers are now receiving more and more attention. The addition of organic fertilizers can improve soil structure, prevent soil compaction and increase yield. Summary of t...
