Structure of Understorey Vegetation in Eucalyptus Plantations

桉树人工林林下植被结构的研究

P fertilization increased P accumulation in understorey and litter, but N and K.

施P肥同时还明显增加了林下植被和林下凋落物P的积累量，但不能明显增加N和K的养分积累量。

Villosum site. The fruit yield increased with sun light level when the light level in understorey was under 35% of full sun light ( P < 0.05).

当林下光照水平在全日照的35%以下时，阳春砂仁果实产量随林下日照水平变化呈线性增加（P<0.05）。

Understorey woody plants were similarly depauperate.

林下的木本植物同样亦发育不全。
