A kind of micro-ecological compound bacterial agent and its method for treating solid crop cultivation substrate

Abstract

The invention belongs to the technical field of microbial fermentation. In order to solve the problems that the existing cultivation substrates cannot be reused, the repeated use is likely to cause continuous cropping obstacles, and become the carrier of soil-borne disease pollution and centralized transmission, etc., it provides a micro-ecological compound bacterial agent and its solid-state treatment agent. A method for cultivating substrates for crops. The micro-ecological compound bacterial agent is composed of Bacillus amyloliquefaciens LH‑1, Bacillus licheniformis, Pseudomonas cichorium, moderate propionic acid producing bacteria, hyperthermia, Bacillus stearothermophilus, Candida tropicalis, Trichoderma harzianum , Streptomyces, Actinomyces mazei, and Frankia are mixed in a certain proportion. Effectively kill pathogenic bacteria and overcome continuous cropping obstacles; scientifically use the combination of biological and physical measures to solve the problems existing in the reuse of substrates, ensure the quality and safety of fruits and vegetables and zero pollution to the environment, reduce farmers' production costs, and ensure the quality and safety of agricultural products. Protect the ecological environment; the cultivation substrate can be reused many times without affecting the growth and development of crops.

Description

technical field [0001] The invention belongs to the technical field of microbial fermentation, and in particular relates to a micro-ecological compound bacterial agent and a method for treating solid-state crop cultivation substrates. Background technique [0002] Substrate cultivation is a soilless cultivation method that uses a solid substrate (medium) to fix plant roots and absorb nutrient solutions and mineral elements through the substrate. Fruit and vegetable substrate cultivation not only effectively solves the contradiction between protected agriculture and open field agricultural production, realizes high absorption of water and fertilizer by vegetables, and shortens the growth cycle of facility fruits and vegetables. At present, matrix cultivation technology has been widely used in more than 100 countries, and more than 90% of commercial soilless cultivation adopts matrix cultivation. Substrate cultivation represents the development trend of modern facility agricu...
