中文摘要：

为研究棉田间作对田间小气候的影响,共设置4个处理：棉花单作、棉花间作花生、棉花间作甘薯、棉花间作大豆,研究不同间作棉田群体对不同层次的光强、土壤温度以及棉花农艺性状及产量的影响。结果表明,与棉花单作系统相比,间作系统可通过改变受光结构、土壤温度、土壤含水量等促进棉花生长发育,利于棉花种植获得高产;棉花间作大豆模式是较适宜在红壤旱地推广的间作模式。

英文摘要：

In order to study the effect of field microclimate of cotton intercropping,a field trial comparing a cotton monoculture system,a cotton-peanut intercropping system,a cotton-sweet potato intercropping system and a cotton-soybean intercropping system were conducted.For each system,the illumination intension distribution and soil temperature at different layers,agronomic traits and yield of cotton were determined.The results showed that：compared with the cotton monoculture system,intercropping system could change the light structure,soil temperature and soil moisture content which promoted cotton growth and high-yield.The cotton-soybean intercropping model was better,and was more suitable to be popularized in the area of red soil upland.
