试验以粉碎后的玉米秸秆为原料进行好氧微生物降解制造有机肥 ,通过比较不同含水率和通气条件对秸秆降解效率的影响 ,以及降解过程中温度、pH、微生物量的变化 ,总结出微生物降解玉米秸秆过程的变化规律。由试验可知 ,水分与通气条件均是影响发酵效果的重要因素 ,且制造堆肥的最佳含水率在 60 %～ 70 %。
In the experiment, the comminuted corn stalks were used as raw materials to produce organic fertilizer by aerobic microbial degradation. By comparing the effects of different moisture content and aeration conditions on the degradation efficiency of straw and the changes of temperature, pH and microbial biomass during the degradation process, microbial degradation Variation of Corn Straw Process. It can be seen from the test that moisture and aeration conditions are all important factors affecting the fermentation efficiency, and the optimum moisture content for compost production is between 60% and 70%.
