摘要: 为了筛选出红壤旱地上优化的棉田种植系统,从农田生态系统的生产功能、能流特征、物流特征、价值流特征,以及养地效果等5个方面对红壤旱地6种棉田立体种植模式的功能和效益进行了分析,并采用因子分析法和SPSS13软件从生态效益、经济效益和社会效益3个层次10个指标对各种植模式进行了综合评价。结果表明,处理C(豌豆/棉花+玉米)综合效益指数值最大,为0.982,其次是处理D(油菜/棉花+花生),其综合效益指数值为0.850,这两种立体种植方式是最适宜在南方红壤旱地上推广应用的高效棉田种植系统。

Abstract: To choose the better cotton field cropping systems, we had analyzed 6 different cotton field cropping systems from characteristics of product function, energy flow, value flow and integrating utilization and cultivation of soil. Comprehensive evaluated each cropping system from 10 indexes of ecology benefit, economic benefit and social benefit by way of Factor analysis and software SPSS13. The result shows that, treatment C (pea/cotton+corn)and D (rapeseed/cotton+peanut)have the best comprehensive benefit and considered to be the best cropping systems extending on upland red soil.
