摘　　要：以长江流域滩地2011、2013、2015年造林的杨树林为研究对象,林下种植油菜,于油菜抽薹期观测林内小气候因子,成熟期测定油菜单位面积产量及品质指标,以期分析不同林龄下油菜单位面积产量的差异及小气候因子对油菜的影响。结果表明:2015年所栽杨树林内空气温度、土壤温度与含水量、光合有效辐射均高于2011、2013年; 2011、2013、2015年所栽杨树林内油菜每平方米产量分别为81. 5～222. 0、101. 0～264. 0、127. 5～399. 0 g,油菜籽脂肪含量分别为28.4%、30.6%、35.7%,其中2015年造林的复合模式内油菜单位面积产量差异率、平均产量及脂肪含量均最高。相关分析表明,平均产量、脂肪及芥酸含量均与小气候因子相关性较高。The poplar forests afforested in 2011, 2013 and 2015 in the Yangtze River valley were taken as the researched objects. Rape was cultivated under these poplar forests. The microclimatic factors in poplar-rape system at rapeseed bolting stage were observed, and the yield per unit area and quality indexes of rape at maturity stage were measured, in order to analyze the difference in rape yield per unit area under different aged poplar forests, and to understand the effects of microclimatic factors on rape. The results showed that the air temperature, soil temperature, soil moisture content, and photosynthetic active radiation in the poplar forest afforested in 2015 were all higher than those in the poplar forests afforested in 2011 and 2013. Under the poplar forests afforested in 2011, 2013 and 2015, the rapeseed yield per square meter was 81.5-222, 101-264 and 127.5-399 g, respectively, and the fat content in rapeseed was 28.4%, 30.6% and 35.7%, respectively. Under the poplar forest afforested in 2015, the per-unit-area yield difference rate, average yield and fat content of rapeseed all were the highest. The correlation analysis revealed that the average yield, fat content and erucic acid content of rapeseed were highly correlated with the microclimatic factors.
