High-calcium organic fertilizer

Abstract

The invention discloses a high-calcium organic fertilizer. The high-calcium organic fertilizer is prepared from the following raw materials in parts by weight: 12 to 15 parts of shell meal, 33 to 35 parts of bagasse, 16 to 18 parts of fish bone meal, 3.4 to 3.6 parts of chitin, 15 to 16 parts of soybean flour, 3 to 4 parts of chitosan oligosaccharide, 4 to 5 parts of limestone powder, 5 to 6 parts of calcium chloride, 25 to 27 parts of composted rough grains, 22 to 24 parts of sunflower straws, 1.2 to 1.4 parts of dodecyl dimethyl betaine, 0.9 to 1.1 parts of Tween 80, 16 to 19 parts of kaolin and a proper amount of water. The high-calcium raw materials including the shell meal, the fish bone meal and the like are added into the organic fertilizer and are combined with the addition of the chitin, the chitosan oligosaccharide and the like and fermentation treatment of microorganisms, so that a lot of soluble calcium salts capable of being absorbed and utilized by plants can be formed; a unique process design of fertilizer grain production is adopted, and thus the conversion rate of effective components in the fertilizer is great, so that the high-calcium organic fertilizer has a relatively good utilization effect on high-calcium crop production.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a high-calcium organic fertilizer. Background technique [0002] With the increasing level of agricultural modernization, organic fertilizers are gradually replacing ordinary chemical fertilizers and becoming an important fertilizer in agricultural production. Organic fertilizers have many advantages such as complete nutrition, improved soil, and increased fertilizer utilization. However, the organic fertilizers currently available on the market have many defects. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, they cannot meet the needs of soil pollution restoration. Simple soil structure Improvement cannot improve the quality of crops in polluted soil; third, the supply of nutrients is slow, and although it is more effective than ordina...

However, the organic fertilizers currently available on the market have many defects. First, a large amount of greenhouse gases are likely to be generated during the preparation process, and are discharged into the atmosphere without control, causing air pollution; second, they cannot meet the needs of soil pollution restoration. Simple soil structure Improvement cannot improve the quality of crops in polluted soil; third, the supply of nutrients is slow, and although it is more effective than ordinary chemical fertilizers, it is difficult to meet the nutrient needs of plants when they grow vigorously; fourth, fertilizers are bulky and inconvenient to transport and store; fifth, for special The soil environment such as acid-base, drought-humidity, soil lacking some elements and the nutrient requirements of specific crops are not effectively targeted
