玉米大豆间作效应分析

An Analysis of Effect of Intercropoing of Maize with Soybean

通过玉米与大豆间作不同带型和密度试验的结果表明，玉米大豆２：１带型、玉米５．２５万株／ｈｍ￣２、大豆１９．５万株／ｈｍ￣２产量最高，效益最好；玉米大豆产量与各自的群体数量和光照强度呈极显著正相关，而玉米的群体数量与大豆产量呈显著负相关；总产量与玉米产量、群体数量、株高和大豆株高呈显著正相关。

Different stripe patterns and density of intercropping of maize with soybean were studied.The results showed that when stripe patterns of maize and soybean wastwo to one with 52500 maize plants/hm￣2 , and 195000 soybean plants/hm￣2 , yields werethe highest ,and economic returns were the maximum. Maize and soybean yields were inextremely significant positive correlation with the quantities of each population and lightintensity,while the quantities of maize population was in significant negative correlationwith soybean yield Total yields were in significant positive correlation with maizeyields,population quantities,plant height and soybean plant height.
