Organic fertilizer preparation formula and preparation and application methods thereof

Abstract

The invention discloses a preparation formula of an organic fertilizer and a preparation and application method thereof. The preparation formula of the organic fertilizer comprises the following raw materials: rabbit manure; fine bran; a phosphate-solubilizing microbial agent; a silicate microbial agent; rapeseed oil residue; carbonizing the rice hulls; root nodules and nitrogen-fixing bacteria inoculants; and water. The preparation process of the organic fertilizer has the advantages of better fermentation process, high harmful substance removal rate, lower cost, simplicity and convenience in raw material purchase, and greatly shortened fermentation period compared with aerobic fermentation, and in addition, the carbonized rice hulls of porous media are selected as a microbial community reproduction place, so that the interaction rate of microorganisms and soil can be ensured, and the yield of the organic fertilizer is improved. When being applied, the organic fertilizer can be directly sprayed into soil where crop roots are located by a screen, so that the existing organic fertilizer packaging, granulating and transporting cost can be reduced.

Description

technical field [0001] The invention relates to an organic fertilizer preparation formula and a preparation method thereof. Background technique [0002] The existing organic fertilizers are mainly derived from the natural decay of animals and plants. They are applied to the soil to provide nutrients for the soil and promote crop growth and vegetative growth. After a long period of natural microbial action, the harmful substances are eliminated and the soil Beneficial substances with improving effect. The existing organic fertilizers are basically prepared by the accumulation of livestock and poultry manure and plant decay. The fermentation time is long, the removal rate of harmful substances is low, and a large amount of ammonia gas will be volatilized during application, which will damage plants and their capillary roots. At the same time, the quality of existing organic fertilizers in the market is uneven, the unit price is too expensive, the overall organic fertilizer c...

AI Technical Summary

Problems solved by technology

The existing organic fertilizers are basically prepared by the accumulation of livestock and poultry manure and plant decay. The fermentation time is long, the removal rate of harmful substances is low, and a large amount of ammonia gas will be volatilized during application, which will damage plants and their capillary roots.

At the same time, the quality of existing organic fertilizers on the market is uneven, the unit price is too expensive, the overall organic fertilizer content is low, and the fermentation is not complete, which is easy to cause soil compaction and salinization.
