内蒙古宁城立体栽培光能利用率分析

Analysis of Sun Light Utilized Coefficiet of Multiple Cropping in the Ningcheng County of Inner Mongolia

1995 ～1998 年,实施了《内蒙古东南部水浇地立体栽培技术的研究》。4 a 研究结果表明,立体栽培比等行距单作玉米增粮38-5 % ,增值100-4 % ,增效117-1 % 。光能利用率达到1-780 % ,比等行距单作玉米提高0-698 个百分点。

Multiple cropping test have been done from 1995 1998.The results showed that its yield increased 38.5% as compared with single cropping of yield,100.4% increase of production value,117.1% increase of economy benefit.Sun light utilized coefficient reached 1.780%,it was 0.698 points of percentage more then the control.
