Abstract

The invention belongs to the field of microbial soil conditioners, and particularly relates to a method for preparing an agricultural microbial soil conditioner through solid fermentation of industrial and agricultural wastes. According to the method provided by the invention, industrial and agricultural wastes are used as main raw materials, and bacillus subtilis is used for solid fermentation toprepare the agricultural microbial soil conditioner. The invention provides the solid fermentation method of the soil conditioner; by using low-price organic wastes as raw materials, the production cost is far lower than that of a liquid fermentation inoculant and is about 3-5 times lower than that of the liquid fermentation inoculant, and the product has high viable bacteria content which is more than 5 billion / g and up to 10 billion / g, and completely meets the requirements of raw materials for processing the soil conditioner. In the production process, organic materials are properly decomposed through microbial culture, decomposition of macromolecular organic matters is accelerated, and meanwhile, multiple crop growth promoting components are secreted, so that the process is very suitable for processing requirements of products such as biological soil conditioners, biological organic fertilizers and the like.

Description

technical field [0001] The invention belongs to the field of microbial soil conditioners, and in particular relates to a method for preparing agricultural microbial soil conditioners by solid fermentation of industrial and agricultural waste. Background technique [0002] Bacillus subtilis is a class of mesophilic, aerobic, endospore-forming, Gram-positive rod-shaped bacteria. The fungus is widely distributed in nature, easy to isolate and cultivate, harmless to humans and animals, and friendly to the environment. It can inhibit the survival and activity of specific crop pathogens through competition, antibiosis, parasitism, bacteriolysis, and induction of plant resistance among organisms, and has significant antibacterial and disease prevention effects. Bacillus subtilis grows fast, has simple nutrition, and can produce heat-resistant and stress-resistant spores. Its spores have strong stress resistance, are good for preservation, and can endure extreme external environmen...
