Screening Trial on the Superior Plant Adaptable for Agroforestry in the Hilly Region in Tanhang Mountain

According to the natural characteristics of the hilly region in Tanhang Mountain, the screening trial on the superior species of water soil conservation tree, forage grass,herb adaptable for agroforestry was conducted in order to optimize the agroforestry structure. The results showed that Rhus typhina Nutt.,Robinia pseudoacacia L., Acer truncatum Bge.Ailanthus altissima Swingle,Platycladus orientalis (L.) Franco were the superior species of water soil conservation tree adaptable for agroforestry in the limestone hilly region,and that Medicago sativa L. was the most superior species of forage grass, Pseudostellaria heterophylla Miq., Pinallia ternnata Briet., Blettilla striata (Thunb.) Rchb. f. and Asarum sieboldii Miq. were the superior species of herb.
