摘要
通过调查分析 ,杨树、柠条混交林的生长量和生物量均大于纯杨林 ,混交林能增强杨树的抗逆性及生长机能 ,并且根系的分布更均匀、更合理 ,更能充分利用土壤空间、养分和水分。因此 。
Investigation showed that growth and biomass of the mixed forest of poplar with Caragana microphylica are more than pure plantation of poplar.Resistances of mixed forest are also better,and roots of which distribute evenly,so that it can make full use of soil space.
