Abstract

The invention discloses a maize straw high-temperature decomposition agent. The maize straw high-temperature decomposition agent is prepared by fermenting and then drying maize straw powder and complex microbial inoculants. The maize straw powder particles in the maize straw high-temperature decomposition agent are loaded with a bacterium mixture containing thermomyces lanuginosus, thermobifida fusca, thermopolyspora flexuosa, streptomyces thermoviolaceus, in-situ composting bacillus licheniformis and bacillus subtilis. Living bacteria count is not lower than 48+/-1 hundred million/g. The average grain diameter of the maize straw high-temperature decomposition agent is 150-650 micrometers, water content is lower than 15%, and pH is 6.0-8.0. By the adoption of the decomposition agent, the lignocelluloses substance and the protein substance in maize straw can be degraded quickly to achieve straw decomposing, and rich simple inorganic carbon sources and nitrogen sources are generated. Decomposed maize straw is made into organic fertilizer to effectively promote the growth of plants and improve the fertility of soil. Soil improvement and environment management are facilitated, and sustainable development of agriculture is achieved.

Description

technical field [0001] The invention relates to a microbial preparation, in particular to a high-temperature decomposing agent for corn stalks and its preparation method and application. Background technique [0002] Corn stalks, as a widespread plant biomass resource, have great bioutilization value. As a large agricultural country, my country produces a large amount of corn stalks every year, but the utilization efficiency of the stalks is very low, and most of the stalks are burned directly, causing serious environmental pollution and waste of resources. The main component of corn stover is lignocellulose, and its components include hemicellulose, cellulose and lignin, which can be decomposed by microorganisms through solid-state fermentation into simple carbon sources that can be absorbed and utilized by plants, and are an excellent substitute for chemical fertilizers. By converting corn stalks into organic fertilizers, environmental pollution and resource waste caused ...
