龙亢农场麦稻轮作秸秆还田对小麦产量的影响

Effect of Straw Returning in Wheat-rice Rotation on Wheat Yield in Longkang Farm

[目的]分析秸秆还田对龙亢农场稻麦轮作区小麦产量的影响。[方法]在大田条件下,设置秸秆全量还田、秸秆半量还田、秸秆不还田3个处理,通过麦稻轮作秸秆还田对比试验,研究龙亢农场小麦-水稻一年两熟种植制度下,不同秸秆还田量对小麦产量的影响。[结果]除有效穗数略低外,秸秆不还田处理其余各指标均高于秸秆还田处理,产量可比秸秆全量还田处理高出1500 kg/hm^(2)左右。[结论]龙亢农场麦稻轮作秸秆还田造成小麦减产。

[Objective]The aim of this study was to analyze the effect of straw returning on wheat yield in rice wheat rotation area of Longkang farm.[Method]In the field conditions,three treatments were set up,including full straw returning,half straw returning and no straw returning.The effects of different straw returning amount on wheat yield under the wheat-rice rotation system in Longkang farm were studied.[Result]Except for the number of effective panicles slightly lower,the other indexes of straw returning treatment were higher than those of straw returning treatment,and the yield was about 1500 kg/hm^(2) higher than that of total straw returning treatment.[Conclusion]Straw returning in wheat-rice rotation reduced wheat yield in Longkang farm.
