摘　　要：[目的]探究配施不同腐熟剂对玉米秸秆还田下冬小麦群体、干物质积累和产量的影响。[方法]在德州市德城区黄河涯镇倪庄村进行大田试验,试验采用单因素随机区组,以冬小麦播种前玉米秸秆还田不配施腐熟剂处理为对照(CK),以玉米秸秆单季还田配施7种不同腐熟剂为处理,研究配施不同腐熟剂对玉米秸秆还田后冬小麦生长和产量的影响。[结果]随着生育期的推移,T1(阿姆斯生物发酵剂)、T4(沃土天地VT有机物料腐熟剂)和T7(还田宝)处理的群体总茎数、干物质积累量和籽粒干物重占比均高于其他处理,且开花期—成熟期(T1为8.13%、T4为8.29%、T7为12.75%)小麦群体总茎数降幅较低,且与其他处理间呈显著差异。T1、T4和T7处理籽粒产量均高于其他处理,与其他处理间差异均达显著性。[结论]玉米秸秆还田配施腐熟剂可有效促进冬小麦生长发育,显著提高作物产量与效益,以T1、T4和T73个处理效果最佳。[Objective]To investigate the effects of different composting agents on the population,dry matter accumulation,and yield of winter wheat under corn straw returning to the field.[Method]A field experiment was conducted in Nizhuang Village,Huangheya Town,Decheng District,Dezhou City.The experiment used a single factor randomized block method,with corn straw returning to the field without applying composting agents before winter wheat sowing as the control(CK),and corn straw returning to the field in a single season with 7 different composting agents as the treatment,the effect of different composting agents on the growth and yield of winter wheat after returning corn straw to the field was studied.[Result]The results showed that with the passage of growth period,the total stem number,dry matter accumulation,and grain dry matter weight of the T1,T4,and T7 treatments were higher than those of other treatments.Moreover,the decrease in total stem number of the wheat population from flowering to maturity(T18.13%,T48.29%,T712.75%)was relatively low,and there was a certain sig⁃nificant difference compared to other treatments.The grain yield of T1,T4,and T7 treatments was higher than that of other treatments,and the differences between them were significant.[Conclusion]It can be seen that returning corn straw to the field with the application of ripening a⁃gents can effectively promote the growth and development of winter wheat,significantly improve crop yield and efficiency,with T1,T4,and T7 being the best treatments.
