Abstract: The study aimed to reduce the obstacles to double- season waxy sorghum continuous cropping, optimize field arrangement of double-season waxy sorghum and soybean intercropping pattern and improve efficiency and yields. The experiment used‘Guojiaohong No 1’and‘Nandou12’as materials, studied the effect of yield and benefit under different field arrangement of waxy sorghum and soybean compound and single planting model. The results showed that total output and total output value of waxy sorghum and soybean compound planting models were higher than that of single planting models. For first waxy sorghum, yield, 1000-kernel weight, spike grain weight and spike length decreased as wide row increased. For second waxy sorghum and soybean, those traits first increased and then decreased. When the wide row increased to 1.7 m, double season waxy sorghum yield was the highest, reached 8352.9 kg/hm2. When the wide row was 1.8 m, the yield of soybean reached to 1888.95 kg/hm2. Total output value and net income of wide row 1.7 m treatments of the two crops were the highest, respectively 47293.92 kg/hm2 and 29976.42 kg/hm2, the above two field arrangements were the optimum patterns. The highest value to cost ratio (VCR) was single sorghum planting, the lowest was single soybean pattern.
