贵州乌江、赤水河流域引种撑绿竹试验初报

A Preliminary Report on Introduction Trials of Bambusa pervariabilis × Dendrocala mopsis grandis in Wujiang and Chishuihe Watershed of Guizhou Province

通过贵州乌江、赤水河流域引种撑绿竹四年的试验观测,造林季节在3月下旬至4月上旬可提高造林成活率;造林地在海拔700m以下可避免低温冻害,造林地属于I、II立地级,具有较高的生长量。

An introduction trials of Bambusa pervariabilis × Dendrocala mopsis grandis was conducted in Wujiang and Chishuihe watershed of Guizhou Province. The result showed that ： 1. afforestation activity in the period from late March to early April could have a higher survival rate; 2. It could be free of cold damage in the afforestation sites below 700 - meter elevation ; 3. Higher growth could be obtained in the sites of Ⅰ and Ⅱ classes.
