翁牛特旗流动沙地扦插造林试验初报

The Influence Factors of Pinus sylvestris Planting Survival Rate in Flu Sand

在翁牛特旗选择流动沙地,按不同扦插树种、不同扦插深度和不同扦插时间进行扦插造林的试验结果表明:扦插造林以黄柳、踏郎、沙柳为最好,造林成活率分别达到97.3%、91.4%和87.0%;扦插造林深度以80 m为佳,黄柳、踏郎、沙柳的造林成活率分别达到92.8%、90.0%和86.4%;扦插造林时间以秋季为最佳,黄柳、踏郎、沙柳的造林成活率分别达到95.5%、89.8%和87.5%。

In order to find out the influence of cutting plant measures to the survival rate of planting plant,the cutting planting experiment was completed in Wongnute region by choosing different planting species,different planting depths and different planting times, the influence of cutting planting measures to planting survival rate were studied. The results showed that：（1） The survival rates of Salix gordejevii,Hedysarum mongolicum and Salix cheilophila was the biggest which could reached 97.3% 、91.4% and 87.0%,respectively.（2） 80 cm was the best planting depth,, with which survival rate of Salix gordejevii,Hedysarum mongolicum and Salix cheilophila could reach 92.8%、90.0% and 86.4%, respectively.（3） Autumn was the best planting time, with which survival rate of Salix gordejevii,Hedysarum mongolicum and Salix cheilophila could reach 95.5% 、89.8% and 87.5%, respectively. The results should provide the theory basis for the cutting planting of flu sand.
