Pungent litse fruit residue bio-organic fertilizer as well as preparation method and application thereof

Abstract

The invention discloses a pungent litse fruit residue bio-organic fertilizer, which is prepared from the following raw materials in parts by weight: 50 to 70 parts of pungent litse fruit residues, 10 to 30 parts of soybean straws, 10 to 20 parts of traditional Chinese medicine residues, 10 to 20 parts of melia azedarach leaves and 4 to 8 parts of a microbial agent. The preparation method comprises the following steps of: (1) crushing the pungent litse fruit residues, the soybean straws, the traditional Chinese medicine residues and the melia azedarach leaves by using a crusher to obtain a mixed material; (2) adding the mixed material obtained in the step (1) and the microbial agent into a fermentation tank for fermentation; (3) controlling the temperature of the fermentation tank at 30-50 DEG C, stirring the materials in the fermentation tank once every two days during fermentation, and removing the fermented liquid after fermentation to obtain a fermented fertilizer; and (4) drying the fermented fertilizer in a drying agent, and cooling to obtain the pungent litse fruit residue bio-organic fertilizer with the water content of 9-12%. The organic matter content and the total nutrient content of the pungent litse fruit residue bio-organic fertilizer meet the standard requirements of bio-organic fertilizers, soil can be improved, insects can be effectively killed, and the crop quality can be improved.

Description

technical field

[0001] The invention relates to the technical field of biological fertilizers, in particular to a bio-organic fertilizer made of cayenne slag and its preparation method and application. Background technique

[0002] At present, the most used fertilizers in my country are chemical fertilizers and ordinary organic fertilizers. Chemical fertilizers will have more adverse effects on the soil, while ordinary organic fertilizers mostly come from excrement, compost, and urban garbage, etc., and they all carry certain pathogenic bacteria and heavy metals. Not only are they detrimental to soil health, but they can also be harmful to plants and human health through the soil transmission chain. Therefore, it is necessary to find a fertilizer that can not only fertilize the soil, but also eliminate insects and prevent diseases, so as to make up for the deficiency of commonly used fertilizers.

[0003] my country's plant resources are very rich, and a large amount of resi...
