沙地低产林开发改造主要技术环节分析

Analysis on the Main Technique Link for Exploiting and Transforming the Low-yield Forest in Sandy Land

沙地“小老树”的开发与改造是当前林业生产中亟待解决的问题。为提高出材率 ,可采用挖根采伐的方式 ,在改造中要使规划具备整体性 ,渠路一体化。渠路边单行栽植杨树。不营造片林采用大行距、密株距带状造林形成林农间作的混农林业 ,从而可提高经济效益。

The problem demanding prompt solution in current forestry production is to develop and transform the small aged trees in sandy land. Felling pattern of grubbing root can be adopted in order to increase the rate of recovery. Poplars should be planted in single line by the canal road. Belt planting is adopted in wide row ledge and close space density. It can increase the economic benefits to form the agroforestry with alternation of forest and agricultural crop.
