摘要
经对轮作、连作大豆的12个有关生育性状调查结果表明,轮作大豆的单产主要由株粒数和株干重决定,连作大豆的单产主要由株粒数、株干重和单株荚数决定,根际孢囊线虫对连作大豆产量影响大,达极显著水平。
This paper investigated the 12 growth characteres of rotation and Continuous cropping seybean. showed the yield of rotation soybean mainly dominated by total seed mumber and dry weight per plant, The yield of continuous cropping soybean mainly dominated by total seed number, dry weight and pod mumber per plant. The number of SCN in the phizosphere has an negative relationship with the yield of continuons conttinuons cropping soybean.
