| 摘 要： | 为了减轻双季糯高粱连作障碍，优化双季糯高粱、大豆田间配置结构，提高两季作物产量效益，以常规双季糯高粱‘国窖红1 号’、‘南豆12’为试验材料，研究不同田间配置方式对糯高粱、大豆复合种植、净作模式下产量、效益的影响。结果表明：复种模式下作物总产量、总产值均高于双季糯高粱、大豆净作模式，头季糯高粱产量、千粒重、穗粒重和穗长随厢宽的增加而降低，再生季糯高粱、大豆表现为先增后减的趋势；双季糯高粱总产量最高的为1.7 m开厢处理，达8352.9 kg/hm2，大豆产量最高为1.8 m开厢处理，达1888.95 kg/hm2，两作物总产值、净收益以1.7 m 开厢处理最高，分别为47293.92 kg/hm2、29976.42 kg/hm2，其次为1.8 m开厢处理，以上两处理为最优田间配置方式。产投比以净作双季糯高粱最大，净作大豆最低。

| 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 ＇Nandoul2＇ 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 the lowest was single soybean pattern. to cost ratio （VCR） was single sorghum planting, |
