Liquid straw composting agent

The technology of straw decomposing agent and liquid inoculum is applied in the directions of organic fertilizers, microorganisms, fungi, etc., which can solve the problems of unsatisfactory decomposing effect, single mixing of inoculum freeze-dried powder, and few functional strains, so as to shorten the decomposing effect. Time, faster decomposition rate, less antagonistic effect

example 1

[0018] Weigh the straw, put it into a shredder and cut it into 5cm small pieces and mix it to obtain a mixed straw section, mix the mixed straw section with the garden soil at a mass ratio of 1:20, add 0.1% sucrose of the garden soil quality after mixing, and stir for 10 minutes Sealed and fermented at a temperature of 35°C and a relative humidity of 60% for 3 days to obtain a fermentation substrate, weighed 20 g of the fermentation substrate and added it to 800 mL of sterile water, stirred for 10 min, soaked for 5 h, and filtered to obtain a seed liquid. In terms of parts by weight, 50 parts of sucrose, 60 parts of peptone, 3 parts of potassium dihydrogen phosphate, 0.3 parts of magnesium sulfate heptahydrate, 3 parts of calcium carbonate, and 2 parts of ammonium dihydrogen phosphate were selected and added to 800 parts of deionized water, stirred and mixed After 10 minutes, sterilize under ultraviolet light for 15 minutes to obtain a liquid medium, inoculate the seed liquid i...

Abstract

The invention discloses a multi-strainliquid straw composting agent, belonging to the technical field of solid waste treatment. The liquid straw composting agent is prepared by the steps of cutting straws of wheat and corns, mixing with rural soil and saccharose, standing, soaking the straws,filtering,collecting filtrate, inoculating the filtrate to a self-made liquid culture medium, carrying out culturing to obtain bacteria liquid, cultivating and activating four bacteria by virtue of a self-made oblique plane culture medium, flushing the culture medium, collecting flushing liquid, inoculating the flushing liquid to a self-made fermentation culture medium, carrying out fermental cultivation, filtering, collecting filtrate, combining the filtrate, mixing the filtrate with the bacteria liquid, finally, concentrating, and collecting a concentrated solution, namely the liquid straw composting agent. Bacterial agents of the liquid straw composting agent are rich, and functional strains are more; and meanwhile, the liquid straw composting agent has relatively good composting effect, the composting cycle is effectively shortened, the growth of next-stubble crops is not influenced, the both production and income of the crops can be promoted, and the liquid straw composting agent has relatively good market promotion values.

Description

technical field [0001] The invention discloses a liquid straw decomposing agent and belongs to the technical field of solid waste treatment. Background technique [0002] my country is a large agricultural country, rich in straw resources of various crops, with an annual output of more than 700 million tons of straw. With the resolution of rural energy problems, straw is no longer used as the main fuel, and the phenomenon of concentrated burning has become increasingly prominent, which not only pollutes the environment and endangers people's health, but also fills the air with smog, affecting land transportation and flight safety. Therefore, the rational development and utilization of crop straw is particularly important. [0003] Straw decomposing agent refers to a microbial living preparation that can accelerate the maturity of various crop straws. It is an effective combination of these strains by screening out microbial strains that can decompose cellulose, hemicellulos...
