Bag type rapid fermentation method

Abstract

The invention discloses a bag type rapid fermentation method, which comprises the following steps of: crushing and pretreating an organic material, adding an auxiliary material, gypsum powder and a nitrogen source, adding an exogenous fermentation bacterial agent, filling the materials into a fermentation bag, placing the bag in a fermentation chamber for fermentation. By controlling the temperature and humidity of the fermentation chamber, a good environment for the fermentation is provided, and the purpose of rapid fermentation is achieved by combining the exogenous fermentation agent. Through the detection of the C / N ratio, conductivity, bulk density, porosity and other physical and chemical properties of the substrate in the fermentation process, the fermentation maturity is judged, and the fermentation end point is determined, so that a cultivation substrate with excellent performance is obtained. The fermentation method has short fermentation time and can simultaneously ferment substrates with different formulas, the obtained substrates have good physical and chemical properties; the substrates can increase the germination rate of plants and promote the growth of the plants;and meanwhile, the method achieves the resource utilization of agricultural wastes, domestic garbage and livestock manure and has obvious social benefit, economic benefit and environmental ecologicalbenefit.

Description

technical field [0001] The invention relates to a soilless culture substrate fermentation technology, in particular to a bag-type rapid fermentation method. Background technique [0002] Soilless cultivation technology is a new cultivation method transformed from traditional agricultural production to modernization, scale and intensification, and it is also one of the fastest new technologies in agricultural development in recent years. The characteristics of continuous cropping have developed rapidly around the world. It is a good way to use organic materials such as agricultural production waste, domestic garbage, and livestock and poultry manure as compost to produce soilless culture substrates. At present, they are generally piled up and fully decomposed as fertilizers to provide more soil for the soil. Good organic matter and nitrogen source. However, it takes a long time to fully decompose under natural conditions, and it usually takes 2-3 months or even longer for g...

AI Technical Summary

Problems solved by technology

However, it takes a long time to fully decompose under natural conditions, and it usually takes 2-3 months or even longer for general materials to fully ferment under natural conditions, and different organic materials have different physical and chemical properties, and their decomposing time is also different. Fully decomposing in a short period of time is a difficulty in the composting of agricultural waste; in addition, the traditional stacking fermentation efficiency is low, the fermentation takes up a large area, the fermentation environment is poor, and due to the large fermentation pile and poor air permeability, severe anaerobic fermentation is prone to occur. , resulting in a strong smell in the fermentation pile, breeding mosquitoes, and causing secondary pollution; moreover, if different crop cultivation is involved, the requirements for the physical and chemical properties and fertility of the substrate are also different, and the traditional stacking fermentation method is often difficult to meet these requirements at the same time
