Organic fertilizer

Abstract

The invention discloses an organic fertilizer. The organic fertilizer is prepared from the following raw materials in parts by mass: 30 to 50 parts of straw ash, 8 to 12 parts of lime powder, 5 to 8 parts of chicken manure, 20 to 25 parts of bentonite and 10 to 13 parts of cassava residue, preferably 42 parts of straw ash, 10 parts of lime powder, 6.5 parts of chicken manure, 22 parts of bentonite, and 12.1 parts of cassava residue. A preparation method of the organic fertilizer comprises the following steps of (1) adding the straw ash, the lime powder, the chicken manure, the bentonite and the cassava residue into a crusher, and crushing into particles; (2) uniformly mixing a crushed material in step (1), pouring into a fermenting tank, and fermenting for 10 to 15 days at normal temperature; (3) granulating the fermented mixed material by a granulating machine, wherein the product granularity grades are 1 to 3mm, 4 to 6mm and 6 to 9mm; (4) drying the granules in step (3) by a drying machine until the water content is lower than 6%, and packaging, so as to obtain a finished product. The organic fertilizer has the advantages that the production is simple, the obtaining of raw materials is easy, the cost is low, and the organic fertilizer is suitable for self production of small-scale farmers; the organic fertilizer contains various nutrients required by the plant growth, and the self purifying ability of soil is realized; by adding the lime powder, the insect pest of termite can be prevented and controlled.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to an organic fertilizer. Background technique [0002] At present, with the rapid development of science and technology, chemical fertilizers are used more and more widely in the field of agricultural production. As a fast and efficient agricultural fertilizer, chemical fertilizers are widely used in agricultural production, effectively improving the yield of crops. yield and quality. However, the extensive and long-term use of chemical fertilizers will destroy the aggregate structure of the soil and cause land degradation. In severe cases, it may cause a certain degree of pollution to the air and groundwater, which will fundamentally affect people's health. Therefore, in order to prevent chemical fertilizers from causing land degradation, polluting air and groundwater, and affecting people's health, new organic fertilizers must be found.
