摘　　要：秸秆促腐还田是秸秆综合利用的重要方式之一,增施适宜的秸秆腐熟剂可加快秸秆腐熟速率。在大田试验条件下,以不施腐熟剂的处理为对照,考察了HSSW、YMSW、JSSW、WBSW等4种腐熟剂与不同量尿素配伍对土壤温度、玉米秸秆腐熟程度、小麦产量指标、土壤理化性状的影响。结果表明:秸秆促腐还田能够调节土壤温度;腐熟剂能够促进秸秆腐熟,YMSW的效果最明显;亩配施20 kg尿素的促腐效果优于亩配施10 kg尿素的,小麦产量高于对照处理的;除土壤硝态氮含量外,施用腐熟剂处理的土壤全氮、碱解氮、有效磷、速效钾、铵态氮、有机质含量均高于对照处理的。Promoting straw decomposition and returning to the field is one of the important ways of straw comprehensive utilization,and the application of appropriate straw decomposing agents can accelerate the rate of straw decomposing.Under field experimental conditions,the effects of four types of decomposing agents,including HSSW,YMSW,JSSW,and WBSW,combined with different amounts of urea,on soil temperature,degree of maize straw decomposing,wheat yield indicators,and soil physicochemical properties are investigated,with no application of decomposing agents as a control.The results show that straw promoting decay and returning to the field can regulate soil temperature.Decomposing agents can promote the decomposition of straw,and YMSW has the most significant effect.The promoting effect of applying 20 kg of urea per mu is better than that of applying 10 kg of urea per mu,and the wheat yield is higher than that of the control treatment.Except for the nitrate nitrogen content in the soil,the total nitrogen,alkaline nitrogen,available phosphorus,available potassium,ammonium nitrogen,and organic matter content in the soil treated with decomposing agents are higher than those in the control treatment.
