稻油轮作制中栽培方式对油菜产量和经济效益的影响

Effect of Planting Patterns on Rapeseed Yields and Economic Benefits in Rice-rapeseed Rotation System

为了研究适宜重庆特殊生态地理条件的油菜最佳栽培方式,以‘渝油21’和‘中双11号’为试验材料,通过田间大区对比试验,分析比较不同耕制方式和栽培模式对油菜产量和经济效益的影响。结果表明,免耕移栽产量第一,油蔬两用技术经济效益最高,纯收入达9155.25元/hm2,比对照育苗移栽增收4150.5元/hm2;其次为免耕撒播,节本增效,纯收入为6646.5元/hm2,比对照增收1641.75元/hm2。高密度直播也能实现较好的产量和效益,使得油菜生产机械化在低山丘陵地区成为可能,农机农艺融合方面应进一步加强研究。

In order to study the best rapeseed planting methods of suitable Chongqing special ecological and geography conditions. Comparative Analysis the effects of different planting methods and cultivation methods on rapeseed yield and economic benefits with ＇Yuyou21＇ and ＇Zhongshuang No.1＇ as material through the comparative experiments under Chongqing. The results showed that, yield of no-tillage transplanting was No. 1, and the oilseed-vegetable-dual-purpose technology was the highest economic benefit, net income reached 9155.25 yuan/hm^2, than control seedlings transplanting income 4150.5 yuan/hm^2; followed by no-tillage broadcast sowing, increase efficiency, net income was 6646.5 yuan/hm^2, an increase of 1641.75 yuardhm^2 more the control. Besides, high density direct seeding can also achieve better yield and benefit, the rapeseed production mechanization is possible in low fusion should further strengthen the research. mountain and hilly area, agricultural machinery and agronomy
