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835.29 kg/hm2,大豆产量最高为1.8 m开厢处理,达1 888.95 kg/hm2,两作物总产值、净收益以1.7 m开厢处理最高,分别为47 293.92、2 997.642 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
In order to alleviate the continuous cropping obstacle of double season glutinous sorghum and to optimize the disposition structure of double sorghum and soybean field and improve the yield and benefit of crops in the two seasons, taking the conventional double season glutinous sorghum ’Guojiaohong 1’ and ’Nan Dou 12’ as experimental materials, The effects of different field allocation methods on the yield and benefit of waxy sorghum, soybean compound planting and net cropping patterns were studied. The results showed that the total crop yield and the total output value of crop under double cropping were higher than those of double cropping waxy sorghum and soybean, and the yield, grain weight, grain weight and ear length of waxy sorghum in the first season decreased with the increase of breadth, Sorghum and soybean showed the trend of first increase and then decrease; the highest yield of double-season glutinous sorghum was 1.7 m box opening, reaching 835.29 kg / hm2, and the highest soybean yield was 1.8 m box opening processing, reaching 1888.95 kg / hm2, The gross output value and net income of the two crops reached the highest at 1.7 m box opening, reaching 47 293.92 and 2 997.642 kg / hm2, respectively, followed by 1.8 m box opening. The above two treatments were the optimal field allocation methods. Production and investment ratio to net double-waxy sorghum as the net, the net net soybean minimum
