动物粪便、尿素和秸秆腐熟剂对稻草秸秆腐熟进程的影响

Effects of Swine Manure,Urea and Microbial Blends on Maturity Process of Straw

为探讨外源氮与秸秆腐熟剂对稻草秸秆腐熟效果的影响,在秸秆中添加不同比例的动物粪便、尿素和秸秆腐熟剂,从而筛选出适宜的处理方式。结果表明:添加了动物粪便和尿素的处理效果好,秸秆腐熟剂能促进动物粪便和尿素对秸秆的腐熟进程,而未进行任何处理的秸秆和只添加秸秆腐熟剂的处理腐熟效果不理想。理想的秸秆处理为处理Ⅰ(100g秸秆+100g动物粪便+1g腐熟剂)、处理Ⅱ(100g秸秆+100g动物粪便)、处理Ⅲ(100g秸秆+1g尿素+1g腐熟剂)和处理Ⅳ(100g秸秆+1g尿素)。

For discussing the effects of exogenous N and microbial blends on maturity process of straw,and selecting appropriate treatment,the swine manure,urea and microbial blends were added to straw with various proportion.The results showed that the effect of straw added with swine manure was better than added with urea.The microbial blends cloud promote the maturity process of straw,but the effect was unsatisfactory.The appropriate treatments were treatment Ⅰ（straw 100 g ＋ swine manure 100 g ＋ microbial blends 1 g）,treatment Ⅱ（straw 100 g ＋ swine manure 100 g）,treatment Ⅲ（straw 100 g ＋urea 1 g ＋ microbial blends 1 g） and treatment Ⅳ（straw 100 g ＋ urea 1 g）.
