Abstract

The invention provides a composite microbial fertilizer for reducing soil pests and diseases of tobacco, and a preparation method thereof, and belongs to the field of bioorganic fertilizers. The composite microbial fertilizer includes a plurality of fertilizer particles, and every fertilizer particle sequentially comprises a core, a middle layer and an outer layer from inside to outside. The core comprises a nitrogen fertilizer, a phosphorus fertilizer, a potassium fertilizer, mineral powder and a binder. The middle layer comprises fly ash and humic acid. The outer layer comprises animal dung, corn stalks, Camellia oleifera shells, proteins and a first microbial agent. The preparation method comprises the following steps: mixing and granulating first materials to obtain first fertilizer particles; attaching second materials to the surfaces of the first fertilizer particles to obtain second fertilizer particles; fermenting third raw materials to obtain a first mixture; and attaching the first mixture to the surfaces of the second fertilizer particles in order to obtain the composite microbial fertilizer particles. The composite microbial fertilizer prepared in the invention can be applied to reduce the top application frequency, and substantially improve the output and the quality of the tobacco and reduce the soil pests and diseases.

Description

technical field [0001] The invention relates to the field of bio-organic fertilizers, in particular to a compound microbial fertilizer for reducing underground tobacco pests and a preparation method thereof. Background technique [0002] Tobacco is an economic crop, and tobacco production provides raw materials for the tobacco industry. Nicotiana is a tubular flower family, Solanaceae annual or limited perennial herb, slightly lignified base. Tobacco leaves are produced into various tobacco products through industrial processing to meet the consumption needs of smokers. Although tobacco products are not the necessities of people's life, they have become an indispensable hobby in the lives of the majority of smokers. [0003] With the expansion of tobacco planting area year by year, continuous cropping of tobacco fields is a phenomenon existing in many tobacco areas. Some of the high-quality tobacco areas that have been planted for a long time often appear: serious croppin...
