Abstract: By double-factor randomized block field test , shoot growth , leaf yield , and the contents of main medicine components flavonoid and terpin of 3 densities and 4 heading heights in leaf-use Ginkgo biloba forest were tested .The results showed that the suitable density and heading height treatment could improve the illumination conditions for the crowns , promote the germination and growth of branches , increase the number , area and yield of leaf in each tree .The contents of leaf flavonoid and terpin content decreased with the increase in the heading height.Denser forest (60 ~ 40 cm 20 cm)at early stage would make a higher yield of leaf .The heading height can be shortened properly on the precondition that it will not affect the yield of leaves .The stem can be cut at 30 - 50 cm from the ground .[ Ch , 10 tab .5 ref .]
