摘　　要：在香樟林下建立复合经营体系,比较林下不同光环境下熊掌木(Fatshedera lizei)苗木生长动态,探讨林下育苗的可能性,为提高土地利用率提供科学依据。结果表明,在郁闭度低环境下,可以在短时间内促进熊掌木苗高、叶面积等指标;但为培育出株型稳定的熊掌木苗木,其培育的光照条件应设计为直接辐射13.16mol.m-2、散射辐射1.62mol.m-2,林分郁闭度调整为0.4、透光率达到60%的香樟林下培育苗木。Based on agroforestry systems under camphor trees,we compared the growth dynamics of bush ivy under different light environment, to explore the possibility of breeding bush ivy under trees and provide a scientific basis for increasing the rate of land use. The results shows that ： the low canopy density environment can promote the height, leaf area, and other indicators of bush ivy in short-term; but the direct radiation of 13.16 mol·m^-2 and the scattered radiation of 1.62 mol·m^-2 are needed for the foster of stable and tolerant Fatshedera plants. In practice, the condition of 0. 4 forest canopy density and 60% transmission rate can be suitable for the plant foster.
