为探讨谷林套播油菜轻简化栽培技术，分别以赣油杂5号和丰油730为材料，设置不除草（对照）、1次化学除草、1次人工除草3个处理，于2012～2014年在谷林套播油菜田进行杂草防除试验，以研究不同除草方式对谷林套播油菜生长发育、主要经济性状、产量及产量构成因素的影响。结果表明，1次化学除草和1次人工除草处理后油菜个体生长、产量及产量构成因素、经济效益等指标均明显优于对照，且差异显著；1次人工除草处理除经济效益外，其它指标均优于化学除草处理，但两者差异不显著。从轻简化栽培和经济效益角度综合考虑，谷林套播油菜在3～5叶期采用1次化学除草有很好的杂草防治效果。

The main purpose of this study was to recover lightened and simplified cultivation techniques of interplanting rapeseed in rice,Ganyouza 5 and Fengyou 730 were employed for weed control experiment with no weeding(control),once chemical weeding and once manual weeding treats during 2012 -2014 growing season in interplanting rapeseed field re-spectively,studied on the effects of different treats on growth and development,main economic traits,yield and yield compo-nents of interplanting rapeseed in rice.The results showed that individual development,yield,yield components,economic efficiency and other various indexes of once chemical weeding and once manual weeding treats were significantly higher than the control,and the difference was significant.The other various indexes of once manual weeding treatment were higher than once chemical weeding treatment,the economic efficiency was lower than the latter,overall,the difference between the two treats was insignificant.Based on comprehensive consideration of lightened and simplified cultivation and economic effi-ciency,once chemical weeding could play a very good effect in the three -five leaf stage of interplanting rapeseed in rice.
