Biological mixed bacterial fertilizer and preparation method and application thereof

Abstract

The invention discloses a biological mixed bacterial fertilizer and a preparation method and application thereof. The biological mixed bacterial fertilizer is prepared from, by weight, 1-20 parts of a compound bacterial agent, 300-400 parts of organic materials, 500-600 parts of inorganic materials, 800-1000 parts of chemical fertilizers, 5-10 parts of trace elements, 300-500 parts of waste liquid, 30-50 parts of amino acid salts and 50-100 parts of additives.

Description

technical field [0001] The invention relates to microbial fertilizer production technology, and mainly relates to a biological mixed bacterial fertilizer and its preparation method and application. Background technique [0002] Green agricultural products or organic agricultural products require products produced under strict field management in a non-polluting natural environment with complete nutrients. In order to ensure the nutrient supply of products, farmyard manure is mostly used as fertilizer at present. However, the amount of farmyard manure is limited, and the fertilizer performance is uncontrollable, making it difficult to meet high-standard agronomic requirements. In this case, the role of microbial fertilizer is highlighted. Microbial fertilizer is an agricultural fertilizer made by using biotechnology to produce beneficial microorganisms together with appropriate carriers. Biological bacterial fertilizer can provide various nutrients for crops through microb...
