为探讨秋洋芋/油菜套作栽培的产量潜力及其区域适应性和关键栽培技术，分析该项技术的效益表现和推广价值，2011~2012年在重庆市永川区和开县开展了该套作模式的大区对比试验。结果表明，秋洋芋/油菜套作模式在稻油轮作区域种植可增收一季秋洋芋，效益显著。两试点秋洋芋平均产量为13567.35 kg/hm2，油菜籽平均产量为2663.25 kg/hm2，总产值达38773.05元/hm2，纯收入23000.55元/hm2，比净作油菜平均增收17221.8元/hm2，增收比例达310.3%。稻田秋洋芋/油菜套作是一项经济效益和生态效益非常显著的高效栽培新技术。

In order to expIore the yield potential, regional adaptabiIity and key cuItiva-tion techniques of autumn potato/rapeseed intercropping system, and analyze its benefit performance and popuIarization value, the contrast experiments of Iarge re-gion were conducted in Yongchuan and Kalxian of Chongqing city from 2011 to 2012. The resuIts showed that the benefit increasing effect was significant because autumn potato/rapeseed intercropping patterns couId galn more one season potato in rice-rapeseed rotation area. The average yield of autumn potato and rapeseed in two test points were 13 567.35 and 2 663.25 kg/hm2 respectiveIy, and the total out-put value and net income reached to 38 773.05 yuan/hm2 and 15 772.5 yuan/hm2 respectiveIy, and cash income attalned 38 773.05 yuan/hm2, and net income reached 23 000.55 yuan/hm2, and the increased income was 17 221.8 yuan/hm2 and it increased by 310.3% comparing with rapeseed of soIe cropping. Therefore, the autumn potato/rapeseed intercropping in rice field is a new efficient cuItivation technique with very significant ecoIogical and economic benefit.
