摘要
用 3种不同腐解剂对玉米秸秆作堆腐腐解试验 ,达到加速秸秆腐解还土、增加土壤有机质的作用。结果表明 :不同腐解剂与对照 (CK1)相比可增加有机质 5 .6%～ 15 .3% ;不同腐解剂加入尿素堆腐与对照(CK2 )相比可增加有机质 11.5 %～ 13.4 % ;加入尿素还能调节秸秆腐解过程中的 C/ N。
Three kinds of decomposition accelerators were used to facilitate decomposition of maize stalk for the purpose of increasing organic matter of soil. The results showed that the decomposition accelerators increased organic matter by 5.6%～15.3% comparing with the check, while the stalk added with urea it could increase organic matter by 11.5%～13.4%. Meanwhile urea also could adjust C/N ratio during the process to be in favor of decomposition of maize stalk.
