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.
