摘要
采用不同遮荫方法试验研究了多年生豆科草本植物糙毛假地豆(Desmodium heterocapumDC var.strigosum Van Meeuwen)在弱光下生长发育、光-光合曲线、叶绿素含量及固N活性的变化,结果表明糙毛假地豆耐荫性较强,适于在约20％遮荫条件下生长。
Under shading, the changes of chlorophyll, photosynthetic light response curves, growth, development and nitrogen fixation activity of Desmodium heterocapum DC var. strigosum Van Meeuwen were studied. The results showed that it was a strong shade-resistant legum,20% shading was suitable for its growth.
