Functional microbial agent and preparation method thereof

Abstract

The invention relates to a functional microbial agent and a preparation method thereof. A seed tank (6), a fermentation tank (5), a storage tank (9) and a metering filling tank (10) serving as main devices, a steam engine (2) and a steam filter (16) serving as heating sterilization devices, an air compressor (8), a gas storage tank (7), a freezing dryer (12), an oil-water separator (11), an air coarse filter (13), a pressure-reducing valve (14) and an air fine filter (15) serving as sterile air supply devices and a purified water tank (1), a circulating water tank (4) and a water pump (B) serving as circulating constant-temperature devices are connected through sealing pipelines to constitute a production line, technical processes, namely, an empty fermentation tank disinfection and liquid-added fermentation tank disinfection are carried out and a strain(A) is added into a culture solution in the seed tank (6) and is subjected to technical processes, namely, an inoculation and expanding propagation step and a storage filling step to prepare the functional microbial agent finished product. The functional microbial agent has the characteristics that the fertilizer efficiency is high, the microbial agent can promote plants to prevent insect pests diseases, the soil structure is improved and the microbial agent is non-toxic and harmless and is conductive to environment friendliness, the sustainable and long-term development of the farmland is promoted and increases in both production and income are promoted.

Description

technical field [0001] The invention relates to an inoculum for plants, in particular to a preparation method of a microbial inoculum for promoting the growth of crops. Background technique [0002] my country is a large agricultural country with a population of 1.3 billion. It feeds 20% of the world's population with only 7% of the world's arable land. While the results were remarkable, it came at a heavy price. my country's high agricultural yield is obtained on the basis of extensive use of pesticides and fertilizers. 7% of the cultivated land consumes 30% of the world's chemical fertilizers, causing my country's agricultural ecological environment to face unprecedented damage. Extensive use of chemical fertilizers leads to imbalances in soil nutrient structure, soil compaction, and decline in soil fertility; crop quality declines, high production costs, and reduced benefits; groundwater pollution leads to eutrophication of water bodies, deterioration of water environme...

Problems solved by technology

At present, the application of bacterial agents is developing rapidly, and the good and the bad are mixed. Although some have a large amount of bacteria, they have a high rate of bacteria, the quality is not stable enough, and the effect is not ideal. In the actual use process, the expected effect cannot be achieved.
