中国南方红黄壤旱地多熟制效益的系统分析

我国南方有1.58亿亩的红黄壤旱地,目前生产力水平很低。为了开发红黄壤旱地,挖掘其生产潜力,我们于1986～1989年在江西南昌进行了多熟制的定位试验。结果表明,红黄壤旱地发展多熟制可以大幅度提高土地生产力,培肥地力,达到生态效益、经济效益和社会效益同步增长。同时,为了全面、合理地评价耕作制度,文章采用了综合评判的方法,对本试验的6个多熟制的效益进行了系统分析,对其优劣作了较客观的评价,但这一分析方法还有待进一步完善。

The Systematical Analysis of Efficiency on the Multiple Cropping Systems of Red Upland in Southern China

In order to raise the efficiency of the red upland in southern China,the field experiment on The multiple cropping systems was carried out in Nanchang,Jiangxi from 1986-1989.The re- sults show that,the multiple cropping systems on the red upland can increased the ecological effi- ciency,economic efficiency,and social efficiency.This paper also compared the efficiency among tie six cropping systems by systematical analysis method.
