Lignin granular organic fertilizer

Abstract

The invention discloses a lignin granular organic fertilizer. The lignin granular organic fertilizer is prepared from the following raw materials in parts by weight: 23 to 26 parts of oil foots, 32 to 34 parts of broadleaf sawdust, 14 to 16 parts of buckwheat hulls, 5 to 7 parts of calcium lignosulphonate, 4.3 to 4.7 parts of soybean oil, 3.5 to 3.8 parts of xylose powder, 3 to 4 parts of talcum powder, 8 to 10 parts of monoammonium phosphate, 25 to 26 parts of compost coarse particles, 37 to 39 parts of sunflower straw, 1.6 to 1.8 parts of dodecyl dimethyl betaine, 1.2 to 1.3 parts of Tween 80, 18 to 20 parts of bentonite and an appropriate amount of water. According to the characteristic of a slower biodegradation rate of lignin, the organic fertilizer realizes the nutrient slow-release effect of the fertilizer through the combination of straw biochar and the addition of the broadleaf sawdust and the calcium lignosulphonate; large amounts of nutrients are released in a plant absorbable form, and the pollution problem of excessive elements appeared in the application of the conventional chemical fertilizer is further avoided through the slow degradation of the fertilizer, so that the lignin granular organic fertilizer has better application effects in fertilizer efficiency and environmental protection.

Description

technical field [0001] The invention relates to the technical field of fertilizers, in particular to a lignin particle 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 ord...

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
