| 摘 要： | 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。

| Abstract: | In order to explore the yield potential, regional adaptability and key cultivation techniques of autumn potato/rapeseed intercropping system, and analyze its benefit performance and popularization value, the contrast experiment of large blocks were conducted in Yongchuan and Kaixian of Chongqing city in 2011~2012. The results showed that the ben-efit increasing effect was significant because autumn potato/rapeseed intercropping patterns could gain more one season po-tato in rice-rapeseed rotation area. The average yield of autumn potato and rapeseed in two test points were 13 567. 35 kg/hm2 and 2 663. 25 kg/hm2 respectively, and the total output value and net income reached to 38 773. 05 yuan/hm2 and 15 772. 5 yuan/hm2 respectively, and cash income attained 38 773. 05 yuan/hm2 , net income reached 23 000. 55 yuan/hm2 , and the increased income was 17 221. 8 yuan/hm2 and it increased by 310. 3% compared with net rapeseed crop-ping. So autumn potato/rapeseed intercropped in rice field is a new efficient cultivation technique with very significant eco-logical and economic benefit. |
