不同幼抚方式对樟子松幼树成活率的影响

Effects of Different Nursery Methods on Survival Rate of Young Pinus sylvestris var.mongolica Litv.

本文开展了不同幼抚方式对樟子松幼树成活率的影响试验。结果表明:全面割灌作业的样地中樟子松幼树成活率最高,达到95.67%;以树根为圆心、0.5 m为直径进行割灌作业和折灌作业的样地中樟子松幼树成活率次之,均为95.33%。综合来看,建议在樟子松幼抚过程中,尽量采取小面积割灌和折灌的方式进行幼抚作业。

In this paper,the effects of different nursery methods on the survival rate of young Pinus sylvestris var.mongolica Litv.were studied.The results showed that the survival rate of young P.sylvestris var.mongolica Litv.in the whole cutting bush field was the highest,reaching 95.67%.The survival rate of young P.sylvestris var.mongolica Litv.was 95.33%by cutting and breaking bush with the 0.5 m diameter at the center of the circle.In summary,it is suggested that the small area cutting and breaking bush should be adopted in the nursery process of young P.sylvestris var.mongolica Litv.
