[Effect of leaf picking on the output of radix Astragali seu Hedysari].
Based on an orthogonal design, the experiments have shown that proportion and time of leaf picking are the major factors to influence the thickness and output of Radix Astragali seu Hedysari. If the proportion is extended and the time is delayed, both the thickness and output of the roots will be reduced accordingly. The output will not change much if the time is set on around June 15 each year and the proportion is taken 1 out of 3.
