早熟马铃薯套作不同密度大豆对作物产量的影响
Effects of Early Potato Intercropping Soybean of Different Bandwidth on Crop Yield
摘要
Abstract
In this study,single radom-plot design was conducted to study the effect of different densities on yield in early potato intercropping soybean in Gansu irrigation districts along Yellow River . The results indicated that the yield of relaying soybean changed with plant density,which could be expressed by using a parabola regression equation . With the increase of plant density, plant height,the number of the main stalk,the height of lowest pods increased,but the effective branching,pod number per plant, seed number per plant,grain weight per plant reduced,and seed number per pod,100-grain weight almost kept stable . And the yield of relaying soybean and early potato was the highest with the optimum density of about 150 000 plants/hm2,which are 2 136.03 kg/hm2 and 42 462.5 kg/hm2,respectively.关键词
