全膜双垄沟播马铃薯套种大豆栽培技术及效益评价

Evaluation of Cultivation Technique and Effectiveness of Potato Intercropping Soybean under Double Ridge Mulching and Furrow Sowing Cultivation

在推广全膜双垄沟播栽培技术的基础上,从增加效益入手,进行全膜双垄沟播马铃薯大垄面套种大豆的研究。结果表明,相对马铃薯单种,马铃薯套种大豆的活动积温利用率提高32.94%,水分生产率提高18.4%,土地利用率提高36%,主粮平均产量达6 373.5 kg/hm2,较单种马铃薯增产9.6%,经济纯收入提高25.0%,效益十分明显。

Based on promotion of double ridge mulching and furrow sowing cultivation technique, potato intercropping soybean in large ridge under double ridge mulching was studied from the aspect of improving effectiveness. The results showed that compared with single cultivation of potato, the utilization rate of active accumulated temperature of potato intercropping with soybean was increased by 32.94%; the water production rate was inereased by 18.4%; the land use efficiency was increased by 36%. The average yield of staple foods reached 6 373.5 kg/hm^2, which was increased by 9.6% compared with single .cultivation of potato; the pure economic income was increased by 25.0%, and the effectiveness was very obvious.
