Problems solved by technology

[0005] We also retrieved other domestic methods of producing straw decomposing agents, most of which use wheat bran and rice bran as raw materials, and the production cost is relatively high; the produced decomposing agents have low bacterial activity and poor decomposing effect; some use Single strain, less enzyme production, no obvious decomposing effect

Embodiment 1

[0021] Use Aspergillus oryzae to prepare microbial cells for later use, filter mud, cassava bagasse, and bagasse ash according to the weight ratio of 3:3:1, then add the prepared microbial cells and mix together, add microbial cells The amount of filter mud, cassava bagasse, and bagasse ash is 2% of the total weight of raw materials. Fermentation was started under the conditions of normal temperature and pH value of 7.0. When the temperature of the fermentation substrate rose to 50°C, the substrate was turned over and sprayed with alcohol waste mash to lower it to normal temperature and then continue to ferment. Repeat 3 times for a total of After 25 days of fermentation, it is crushed into particles with a particle size of 1 mm, and then the crushed straw decomposing agent is dried at 75° C. under normal pressure until the water weight percentage is lower than 5%. The straw decomposing agent that can be put into industrial and agricultural use can be obtained by encapsulation...

Embodiment 2

[0023] Use Aspergillus oryzae to prepare microbial cells for later use, filter mud, cassava bagasse, and bagasse ash according to the weight ratio of 4:4:2, then add the prepared microbial cells and mix together, add microbial cells The amount of filter mud, cassava bagasse, and bagasse ash is 4% of the total weight of raw materials. Fermentation started under the condition of normal temperature and pH value of 7.0. When the temperature of the fermentation substrate rose to 55°C, the substrate was turned over and sprayed with alcohol waste mash to lower it to normal temperature to continue fermentation. Repeat 4 times for a total of After 15 days of fermentation, it is crushed into particles with a particle size of 2mm, and then the crushed straw decomposing agent is dried at 80°C under normal pressure until the water weight percentage is lower than 5%. The straw decomposing agent that can be put into industrial and agricultural use can be obtained by encapsulation.

Embodiment 3

[0025] Use Aspergillus oryzae to prepare microbial cells for later use, filter mud, cassava bagasse, and bagasse ash according to the weight ratio of 3:4:2, then add the prepared microbial cells and mix together, add microbial cells The amount of filter mud, cassava bagasse, and bagasse ash is 6% of the total weight of raw materials. Start fermentation under normal temperature and pH value of 7.0. When the temperature of the fermentation substrate rises to 60°C, turn over the substrate and spray alcohol waste mash to lower it to normal temperature and continue fermentation. Repeat 3 to 5 times , after 20 days of co-fermentation, crushed into particles with a particle size of 3mm, and then dried the crushed straw decomposing agent under normal pressure at 85°C until the water weight percentage was lower than 5%. The straw decomposing agent that can be put into industrial and agricultural use can be obtained by encapsulation.

Abstract

The invention relates to a method for producing a straw decomposition agent by using filter mud, cassava residue and waste alcohol sediment liquid. The method is characterized by comprising the steps of batching the filter mud, the cassava residue and bagasse ash according to the weight ratio of (3-4): (3-4): (1-2), then, adding microbial thalli of aspergillus oryzae, uniformly mixing together, fermenting for 25-40 days, and then, crushing and baking at low temperature, thereby obtaining the straw decomposition agent. The straw decomposition agent produced by the method is low in production cost, high in viable strain number and obvious in decomposition effect, and can be used for decomposing objects, such as banana cores, corn stalks, wheat straws, rice straws, grain stalks, rape stalks, weeds, leaves, domestic garbage with high content of fibrous substances, and the like.

Description

technical field [0001] The invention relates to a microbial preparation, in particular to a method for preparing a microbial preparation for decomposing plant stalks, and belongs to the fields of biotechnology and environmental protection engineering. Background technique [0002] my country produces hundreds of millions of tons of crop stalks every year, except for a small amount that is directly used as feed, and a large amount of remaining crop stalks are burned, polluting the environment. For many years, scientists have devoted themselves to using microorganisms to decompose crop straws and return them to the field. At present, straw decomposing agents are used more often. Regarding the preparation of straw decomposing agent, we retrieved the following public documents, for example: [0003] 1. Name: A microbial preparation for rotting crop stalks and its preparation method, authorized announcement number: CN1099393C, legal status: authorized, legal status announcement ...
