【摘要】 为探究麦玉轮作区，玉米秸秆全量还田配施腐熟剂对冬小麦生长的影响，在玉米秸秆全量还田条件下施用2种不同腐熟剂(蔚蓝生物腐熟剂处理和自配处理)。以秸秆还田不施腐熟剂处理为对照，研究各处理对冬小麦生长及产量的影响。结果表明，施用2种秸秆腐熟剂均能明显促进冬小麦叶面积、氮素利用率的提高，且对冬小麦增产效果明显。蔚蓝生物腐熟剂处理、自配处理的氮素利用效率分别比对照高4.71%、3.50%,且与对照间差异达显著水平；蔚蓝生物腐熟剂处理、自配处理的籽粒产量分别比对照高10.02%、7.35%,与对照间差异达显著水平。因此，玉米秸秆还田配施腐熟剂可有效促进冬小麦生长发育，显著提高籽粒产量。该研究为麦玉轮作区玉米秸秆全量还田后冬小麦生长促进和稳产高产提供一定技术参考。更多还原

【Abstract】 In order to explore the effects of maize straw returning combined with maturity agent on the growth of winter wheat in wheat-maize rotation area, two different maturity agents of blue biological maturity agent treatment and self-made treatment were applied under the condition of maize straw returning, and the straw returning without maturity agent treatment was used as the CK to study its effects on the growth and yield of winter wheat.The results showed that the application of two straw decomposing agents could significantly promote the leaf area and nitrogen use efficiency of winter wheat, and the yield increase of winter wheat was obvious.The nitrogen use efficiency of T1 and T2 treatments were 4.71% and 3.50% higher than CK, respectively, and the difference was significant compared with CK.The grain yields of T1 and T2 treatments were 10.02% and 7.35% higher than those of CK, respectively, and the two treatments had significant differences between CK.It could be seen that corn straw returning combined with maturity agent could effectively promote the growth and development of winter wheat and significantly improve grain yield.This research provided certain technical reference for the growth promotion and stable and high yield of winter wheat after full-scale maize straw returning in wheat-maize rotation area.更多还原
