摘要	本发明涉及农作物秸秆利用的领域，具体的说是一种促进棉花秸秆腐解的方法。将干燥的棉花秸秆粉碎成细小颗粒，并将EM菌液按每吨棉花秸秆200-300ml的比例喷洒其上，待用；调节喷洒菌液后的棉花秸秆碳氮比为25∶1-30∶1，然后调节棉花秸秆含水量达65-70%，待用；将上述棉花秸秆进行堆置，并分层添加相当于棉花秸秆重量0.4-0.5%的秸秆腐熟剂，待用；将上述处理后的棉花秸秆在厌氧条件下密封堆放发酵，直至堆腐物颜色变为黑褐色、略有霉味，无臭味，堆腐物料呈疏松的团粒结构，即腐熟完毕。本发明为一种棉花秸秆腐解的技术模式，其为棉秆腐解提供了适宜的营养环境，同时添加了微生物菌剂，提高了腐解效率，增加了腐熟物中营养物质的含量。
其他摘要	The invention relates to the field of utilization of crop stalks, in particular to a method for promoting decomposition of cotton stalks. The method comprises the steps of : crushing the dried cotton stalks into fine particles; spraying EM bacterium liquid in a ratio of 200-300ml per ton of cotton stalks on the cotton stalks for later use; regulating the carbon nitrogen ratio of the cotton stalks sprayed with the bacterium liquid to 25 : 1-30 : 1, and then regulating the moisture content of the cotton stalks to 65-70% for later use; stacking the cotton stalks, and adding a stalk decomposing inoculant which is equivalently 0.4-0.5% of the cotton stalks by weight in a laminated manner for later use; and stacking the cotton stalks after being treated in the previous steps in an anaerobic condition for fermentation, wherein the decomposition is completed until the stacked decomposing material is changed to be black brown in color and slightly stale, has no smell and is in a loose granule structure. The method disclosed by the invention is a technical mode of decomposition of cotton stalks and provides a suitable nutritional environment for decomposition of the cotton stalks; and simultaneously, microbial agents are added, therefore, the decomposing efficiency is improved, and the content of nutrient substances in the decomposed material is increased.
