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13 567.35kg/hm2,油菜籽平均产量为2 663.25 kg/hm2,总产值达38 773.05元/hm2,纯收入23 000.55元/hm2,比净作油菜平均增收17 221.8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 investigate the yield potential of autumn potato / rapeseed cultivation and its regional adaptability and key cultivation techniques, the benefit performance and the promotion value of this technique were analyzed. From 2011 to 2012, it was carried out in Yongchuan District and Kaixian County in Chongqing The area of contrast test. The results showed that the autumn potato / rape intercropping system can increase the yield of autumn potato in the rice paddy field, which has obvious benefits. The average yield of the two potato varieties was 13 567.35kg / hm2, the average yield of rapeseed was 2 663.25kg / hm2, the total output value was 38773.05 yuan / hm2, the net income was 23000.55 yuan / hm2, an average increase of 17 221.8 yuan / hm2, increasing the proportion of up to 310.3%. Paddy field autumn potato / rape intercropping is an economic and ecological benefits is very significant and efficient cultivation of new technologies.
