影响玉米秸秆微生物降解制肥的因素浅析

Study on Organic Fertilizer Produced by the Biodegradation of Corn Straw.

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 %。

An experiment of aerobic microbiological degrading crushed corn straw was carried out in order to produce organic fertilizer. The effects of moisture content and air vent condition were studied .In addition, temperature?pH?microbe quantity were also investigated to find regularity during corn straw biodegradation. The results showed as followed that moisture content and air vent condition were all important factors during fermentation, and the optimal moisture content was between 60%～70%.
