不同清林和抚育方式对马尾松幼林生长的影响初报

The Effects of Different Site Clearance and Tending Methods on the Growth of Young Forest Growth of Pinus Massoniana Lamb.

以往的造林清林方式和抚育方式对原有植被破坏严重,导致水土流失,同时费时费工。针对这些问题,采用双因素裂区试验进行了不同清林方式和抚育方式试验。头两年试验结果表明:定植穴清林方式与带状清林、全面清林不炼山及全面清林并炼山三种方式均差异显著;1年刀抚一次的与刀抚二次、刀锄并用一次、刀锄并用两次之间差异显著。以砍3米留1米的清林方式和一年刀锄并用抚育二次,对马尾松生长效果最佳。

Conventional site clearance and tending method for a plantation is labor intensive and time consuming, and is also destructive to the vegetation resulting in serious soil erosion. According to these problems, an experiment with different clearance and tending methods was conducted by two - factor split - plot design. After two years, the result showed that different clearance methods and difference tending methods had significantly different result. The best growth of Pinus massoniana was gained when methods of banded site Clearance （3m to 1m） and tending twice by both hook and hoe tools were adopted.
