Microbial agent production method

Abstract

The invention discloses a microbial agent production method. The method includes the steps of: 1. taking a high-quality special original strain, and performing single strain bevel activation; 2. subjecting the activated strain to constant temperature culture with a triangular flask in a shaking table separately so as to obtain a seed solution; 3. adding the seed solution identified as pollution-free into a fermentation tank to perform three-stage fermentation culture; 4. when the strain fermentation reaches indexes of technological requirements, using activated humic acid, adding crop nutrient elements or water-retaining agent and the like for solid adsorption; and 5. conducting solid-liquid separation in a plate-and-frame filter press, and performing dehydration treatment to produce the microbial agent suitable for large field and economic crops. Compared with the prior art, the method provided by the invention has the characteristics of simple process and good production efficiency, and the prepared microbial agent conforms to the national standard, and has stable and reliable product quality.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to a method for producing microbial inoculum agents. Microbial compound fertilizer can also be called compound microbial fertilizer. Background technique [0002] my country is the largest country in the production and consumption of chemical fertilizers. As the grain of crops (abbreviation of crops), chemical fertilizers are essential to ensure high and stable crop yields in agricultural production, and increase crop yields in a certain period of time and to a certain extent. [0003] However, the long-term large-scale application of chemical fertilizers has caused increasing harm to the environment and humans, such as: soil acidification, compaction, fertility decline, and groundwater nitrate content exceeding the standard, which in turn leads to the occurrence of various diseases, air pollution, and water eutrophication A series of serious ecological...

Problems solved by technology

[0019] The first is the flat stack composting process; the advantage is small investment and relatively simple process; the disadvantage is that it occupies a large area, is not thoroughly decomposed, and has serious secondary pollution. Poor effect; long production cycle

[0020] The second is the trough-type aerobic fermentation process; the advantage is that it is more thoroughly decomposed, the product quality is high, and the production cycle is 15 to 60 days; The weed seeds of disease insect eggs are not thorough; open, polluted, and the stacking area is large

The existing microbial agent production method includes a variety of devices with different functions. Each device is independent of each other and cannot form a complete production line. The production efficiency is low, the product quality is unstable, and it cannot meet the continuous mass production.
