摘要
对大豆的 5种密植方式的生育状况及产量进行分析 ,结果表明 :在相同密度下 ,宽台密植的 3种处理比其它处理方法叶面积指数和干物质积累和光照强度有明显的增加 ,改善了大豆冠层中、下部的透光性能 ,提高了大豆产量。
In the paper,the yields and growth characters of 5 ways of planting soybean are analyzed.All soybeans are planted in the same density.Compared with other two planting ways,The LAI,dry matter weight and light intensity of soybeans which are planted in close planting way on broad platform are increased.At same time,the amount of light that gets through the middle and low parts of crown is increased,resulting in yield increase.So,we propose a suggestion that the close planting way on broad platform can be used widely in Sanjiang plain.
