连南县杉木幼林抚育比较试验

采用5种不同类型的抚育管理方式，对立地条件和造林质量均相同的新造杉木幼林进行抚育，并对8年生杉木林各项生长指标进行了测定。结果表明，与对照清除杂草抚育方式相比，林农间作、松土埋青、树盘覆草3种抚育方式的杉木高生长与径生长均存在显著或极显著差异。结合投资净现值考虑，树盘覆草抚育方式投资小，又能显著促进杉木高、径和材积生长，达到了“省工节资增效”的目的。

Study on the Tending Ways of Young Chinese Fir Plantations in Liannan County, Guangdong

Chinese fir plantations were tended on 5 different ways in Liannan county, Guangdong province, and the tending effect was compared on growth performance of 8 years old plantations. The results shows that, compared to the control, the tending ways of interplanting crops in forest, lossening the soil and bury grass, pile up the grass around tree all can increase the growth of young plantations significantly. Considering the cost, pile up the grass around the tree is the best.
