Abstract

The invention provides an efficient cotton straw decomposition agent which is obtained by fermenting a composite inoculant, and the composite inoculant comprises bacillus subtilis, bacillus velezensis, aspergillus niger, Kazachstania unisporus, saccharomyces cerevisiae and streptomyces cellulosae. The total number of effective viable bacteria in the prepared efficient cotton straw decomposition agent reaches 3.50-6.80 billion/g, decomposition of cotton straw is accelerated by applying the efficient cotton straw decomposition agent and utilizing strains, and the effective degradation rate of dry matter of the cotton straw is increased.

Description

technical field [0001] The invention belongs to the technical field of microorganisms, and in particular relates to a high-efficiency cotton straw decomposing agent and a preparation method thereof. Background technique [0002] my country is the largest cotton producer in the world. Cotton production accounts for about 30% of the total annual global cotton production. Cotton stalk resources are very rich. In 2018, China's cotton stalk resources were 31.495 million tons. Cotton straw is rich in cellulose, lignin, pentosan, gossypol and other substances. It is an important agricultural renewable resource with high development and utilization value. It has been widely used in feed, fuel, papermaking raw materials, Composite materials, regenerated cellulose rayon, activated carbon, carboxymethyl cellulose, xylose and many other uses. [0003] The effective degradation rate of dry matter of cotton stalk is low, about 33.3%, which is far lower than the effective degradation rate...
