Abstract: The research shows that the stereo-planting pattern of wheat，cotton，pepper and corn with fine disposition in fields structure and agricultural techniques can make the field ecological riche， crop edgy effect，and ecological control of disease and pest fully developed．Compared with wheat-cotton，wheat-pepper interplanting and wheat-corn rotation cropping，the productive value of stereo -planting pattern has increased by 34．1％ ，27．5％ and 94．0％ ，separately，pureincome increases 8188 yuan／hm²，6090．5 yuan／hm² and 12066 yuan／hm²．
