Agricultural slow-release biological compound fertilizer

Abstract

The invention discloses an agricultural slow-release biological compound fertilizer which comprises the following components in parts by weight: 1-3 parts of ammonium nitrate, 2-6 parts of calcium nitrate, 1-3 parts of potassium ore powder, 7-13 parts of rock powder, 25-35 parts of grass carbon powder, 0.1-0.2 part of bacillus thuringiensis var. powder, 0.1-0.2 part of Bacillus popilliae powder, 1-2 parts of amino acid, 0.01-0.02 part of Rhodococcus powder, 0.01-0.02 part of pityrosporion ovale powder, 0.01-0.02 part of Escherichia coli powder, 0.01-0.02 part of Bacillus subtilis powder, 14-25 parts of rape cake, 25-35 parts of chicken manure, 14-23 parts of rice bran and 1-2 parts of rare-earth microelement fertilizer. The solubility of the high-efficiency slow-release biological organic compound fertilizer is low in water, and thus, the nutrient elements are slowly released in soil, thereby reducing the loss of the nutrient elements; and high-efficiency slow-release biological organic compound fertilizer has long and stable fertilizer efficiency, and can continuously supply the nutrients required by plants in the whole growth period.

Description

technical field [0001] The invention relates to an agricultural slow-control biological compound fertilizer. Background technique [0002] In agricultural planting, the normal growth of crops, vegetables, flowers and other plants requires more than a dozen nutrient elements. In addition to carbon, hydrogen, and oxygen that can be obtained from air and water, other nutrient elements need to be absorbed by plant roots from the soil. Usually the soil often lacks one or more nutrients and needs to be supplemented by fertilization. Organic fertilizers have complete nutrients, balanced nutrition, and long fertilizer efficiency. They can provide physiologically clean substances, promote plant growth, improve soil physical and chemical properties, fertilize and improve soil, improve soil microbial cleanliness, and reduce crop diseases. However, by adjusting soil structure and physical and chemical properties, To reduce soil salinity and neutralize soil alkalinity, the production pr...

Organic fertilizers have complete nutrients, balanced nutrition, and long fertilizer efficiency. They can provide physiologically clean substances, promote plant growth, improve soil physical and chemical properties, fertilize and improve soil, improve soil microbial cleanliness, and reduce crop diseases. However, by adjusting soil structure and physical and chemical properties, Reduce soil salinity, neutralize soil alkalinity, the production process is complicated, the application amount is large, the effect is not ideal, the overall cost is high, the fertilizer effect is fast, and the nutrient content is high, but the nutrient content is single
