Special organic fertilizer for corns

Abstract

The invention discloses a special organic fertilizer for corns. The special organic fertilizer comprises, by weight, 25-27 parts of tobacco residues, 40-43 parts of sugar beet pulp, 8-10 parts of pig bone meal, 14-16 parts of corn protein powder, 2-3 parts of oxalic acid powder, 0.9-1.1 parts of grafted acrylamide, 7-9 parts of dipotassium phosphate, 37-40 parts of compost coarse granules, 38-42 parts of sunflower straw, 1.8-2.2 parts of dodecyl dimethyl betaine, 1.2-.15 parts of tween 80, 13-15 parts of bentonite and an appropriate quantity of water. The special organic fertilizer has the advantages that super-absorbent resin is added into the special organic fertilizer and is mixed with organic matters, accordingly, the granule strength of the special organic fertilizer can be effectively improved, the granulation rate of the special organic fertilizer can be effectively increased, and production energy consumption can be reduced; the special organic fertilizer is excellent in water retention capacity and fertilizer maintenance capacity, sufficient nutrition can be provided for growth of the corns by the sugar beet pulp, the pig bone meal and the like, accordingly, labor output in corn planting procedures can be reduced to a great extent, additional fertilizer and supplementary fertilizer times can be reduced, and the corn planting economic benefit can be increased.

Description

Technical field [0001] The invention relates to the technical field of fertilizers, in particular to a special organic fertilizer for corn. Background technique [0002] With the increasing level of agricultural modernization, organic fertilizer is gradually replacing ordinary chemical fertilizers and becoming an important fertilizer in agricultural production. Organic fertilizer has many advantages such as complete nutrition, improved soil, and improved fertilizer utilization. However, the currently commercially available organic fertilizers have many shortcomings. One is that large amounts of greenhouse gases are easily generated during the preparation process, and they are discharged into the atmosphere without control, causing air pollution; the other is that they cannot meet the needs of soil pollution remediation, and the simple soil structure Improvement can not achieve the improvement of the quality of contaminated soil crops; third, the supply of nutrients is slow, altho...

AI Technical Summary

Problems solved by technology

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
