Multifunctional high efficient organic material decomposition agent and preparation method thereof

Abstract

The invention discloses a multifunctional high efficient organic material decomposition agent and a preparation method thereof. The decomposition agent of the invention comprises composite original strains consisting of bacillus amyloliquefaciens, Aspergillus oryzae, Trichoderma viride, and Saccharomyces cerevisiae and an organic material carrier, and an inorganic carrier. Strains of the decomposition agent can be mutualistic, and have complementary advantages. The adaptation is wide, and a plurality of organic matter clastic enzymes can be produced by metabolism. The decomposition agent has high activity and can be used for fermentation and conversion of a plurality of organic materials such as livestock and poultry excrements, crop straws, city sludge, food waste, food processing and pharmaceutical waste residues, and has fast fermentation start, fast deodorization, low temperature resistance, and low moisture resistance. The fermentation period is shorter by 5-7 days than that in the same technology. Fermented and converted organic fertilizers have the obvious rhizosphere ecological regulation and control function, promote the root growth, and improve the root vitality. A plurality of soil borne diseases are prevented by improving the flora diversity, hyperparasitism and biological antagonism.

Description

technical field [0001] The invention belongs to the field of soil chemistry, specifically to the field of organic soil fertilizers, and more specifically relates to a high-efficiency organic material decomposing bacterial agent with multiple uses and a preparation method thereof. Background technique [0002] Aquaculture, planting, sewage treatment, food processing, pharmaceuticals and other industries will generate a large amount of organic waste. If not handled properly, it will cause pollution to the surrounding environment, groundwater and farmland, and affect people's health. Using high-temperature biological fermentation technology, it can kill insect eggs, pathogenic bacteria, etc., convert macromolecular organic substances such as cellulose, lignin, and protein into humus, amino acids, etc., and release nitrogen, phosphorus, potassium, and medium and trace elements, which are suitable for plants. At the same time, the fermentation microorganisms also metabolize and p...

AI Technical Summary

Problems solved by technology

[0004] At present, there are many technologies and products related to decomposing bacterial agents, but most of them have the following problems: (1) The fermentation efficiency is not high

The performance is slow start, slow deodorization, large amount of addition, and long fermentation cycle

(2) Not resistant to low temperature

Most of them are medium-temperature products, which are only suitable for use when the ambient temperature is above 20°C. The fermentation starts for a long time or does not ferment, and it is difficult to carry out fermentation production in winter

(3) Not resistant to low humidity

(4) Single purpose

Most of them are only used for livestock and poultry manure fermentation or straw fermentation, resulting in high R&D and production costs

[0005] The main reason for the problems referred to above is: (1) the bacterial strain composition of the starter is unreasonable, and some strains are a simple combination, which does not consider the mutualistic symbiosis between the constituent bacterial strains, resulting in low fermentation efficiency

(2) The function of the composition strain is single

The expansion of bacterial original bacteria mostly adopts liquid fermentation solid adsorption process, and fungi adopt simple stacking and fermentation, and the sporulation rate is low. After a period of storage, the amount of viable bacteria will drop significantly
