摘　　要：[目的]油菜、小麦收获后秸秆全量还田,在同等施肥管理条件下,对后茬单季水稻产量进行调查,分析产量差异。[方法]供试水稻品种分别为杂交稻丰两优香1号和粳稻武运粳7号。采取大区对比试验。试验区分前茬油菜区和前茬小麦区。油菜收获期5月28日,小麦收获期6月2日,油菜、小麦收获当天实施秸秆粉碎全量还田,同时上水翻耕并保持浅层水,翻耕前施速腐剂30 kg/hm2,另加尿素75 kg/hm2,翻耕后4d机插。[结果]无论是籼型杂交组合还是粳稻,前茬为油菜的较前茬为小麦的单季稻生育期短3 d左右,且产量高,籼型杂交水稻小区平均产量高616.5 kg/hm2,粳稻小区平均产量高630.0 kg/hm2,增产均极显著。[结论]该研究可为今后制定适宜的作物轮作方式提供科学依据。[Objective]The later single-season rice yield was investigated under the same cultivation and management conditions after returning total rape and wheat staws to field,and then analyzed the difference.[Method]The trial rice varieties were indica hybrid rice Fengliangyouxiang No.1 and japonica rice Wuyunjing No.7,resp..The field contrast experiment was used.The trial regions was divided into previous rape region and previous wheat region.Rape was harvested in May 28,and wheat was harvested in June 2,to return total rape and wheat staws to field at the same day of rape and wheat harvest,and to plough and irrigate to keep the shallow water at the same time,to apply 30 kg/hm2-rapidly decomposing reagent and 75 kg/hm2-urea before ploughing,and then to plan rice mechanically 4 days after ploughing.[Result]Not only indica hybrid rice but also japonica rice,the single-season rice growth period of previous rape was short 3 days about than that of previous wheat,and the yield was higher,the average plot yield of indica hybrid rice was higher 616.5 kg/hm2,that of japonica rice was higher 630.0 kg/hm2,and they both obtained the very significant level.[Conclusion]The study provides a scientific basis for drawing up the suitable crop intercropping pattem.
