Abstract: Cassava of Huanan 205 and soybean of Guizao 2 were interplanted as testing materials in different modes. The effects of different intercrop models on growing development, yield, physic and chemical properties of cassava and soybean were studied through determing its agronomic characters, yield and soil nutrients, its economic benefits were also analysed. The results showed that there were noticealbe effects on the growing development and yiels of cassava and soybean in different intercrop models. The intercrop could reduce soil bulk density as well as improve soil structure. The model C, 3 rows soybean intercropped 2 rows of cassava of every border check, had the higest net income.
