摘要:
为合理利用秸秆养分资源，采用尼龙网袋翻埋法进行连续三年秸秆腐解试验，研究寒地半干旱地区水稻秸秆腐解规律变化特性。结果表明：每年10月至次年5月，秸秆腐解进入停滞期；每年6月至9月翻埋到水田中的秸秆进入快速腐解期。秸秆腐解速率随时间的变化整体表现为快-慢-慢的升高过程。秸秆还田1 a时，秸秆腐解率大幅度提高，腐解率达44.3%；秸秆还田2 a时，秸秆腐解率提高相对减慢，其腐解率为19.5%；秸秆还田3 a时，秸秆腐解率变化趋于平缓，秸秆腐解率为5.7%。
Abstract:
To make use of straw nutrient resources rationally,the decompose characteristic of rice straw in semi-arid and cold regions was analyzed through buried nylon mesh bags for three consecutive years.The results showed that the decomposition rate of straws gradually slowed down to a plateau from October to May.From June to September,the straw in the paddy field entered the period of rapid decay.The rate of decomposition of stalk decomposition increased with time and the whole process performance was fast-slow-slow.On the first anniversary of straw decomposition,the rate of stalk decomposition increased rapidly to 44.3%; On the second anniversary of decomposition,the rate of straw decay increased slowly to 19.5% in the second anniversary;On the third anniversary of straw decomposition,the decay rate of straw was tending to a gentle rate,and its straw decomposing rate was 5.7%.
