摘要
薏苡经４／１００００和８／１００００浓度的稀土溶液播前浸种或叶喷后，叶绿素含量、光合强度、产量和干粒重都比对照有不同程度提高，而且品质也明显优于对照，其作用效果基本上是当浓度一定时，以叶喷的为好，方法一定时，以浓度大的为佳。
The treatment of seed soaking or leaf spaying with a 400 or 800ppm rare earth so-lution not only increased the content of chlorophyll,the intensity of photosynthesis,the kernel. yield and the 1000-kernel weight but also improved the kernel quality of Jobstears seed in varying degree,The effect of leaf spraying was better than that of seed soaking for a certain concentration of solution and the effect of higher concentration of solution was better than that of lower one for′acertain method of application.
