Abstract: The purpose of this study was to explain the effects of diversity planting patterns on the growth of waxy sorghum and the control of sorghum anthracnose. It provided theoretical basis for popularizing the cultivation of waxy sorghum and controlling sorghum anthracnose. Waxy sorghum was intercropping with soybean and peanut, and at the same time, applying the technology of crop rotation, the results showed that compared with waxy sorghum monoculture, the diversity planting patterns had certain influence on the agronomic characters of waxy sorghum, such as ear length, 1000-grain weight and panicle grain weight; the net photosynthetic rate, transpiration rate, stomatal conductance and intercellular CO2 concentration in the diversity planting patterns were higher than those of waxy sorghum monoculture, and significant difference with waxy sorghum monoculture; the incidence rate of plant, the severity of the disease and the disease index in the diversity planting patterns were lower than those of waxy sorghum monoculture, and significant difference with waxy sorghum monoculture; the relative control effect of A2B2 planting model was the best, up to 71.95% in the control of sorghum anthracnose. The intercropping pattern of waxy sorghum, soybean and peanut have some influence on the agronomic traits，can improve the photosynthetic ability of waxy sorghum, effectively control the occurrence of sorghum anthracnose, and have great value potential in production.
