杨树低温浸苗造林新技术研究

Research on the New Technique of Poplar Seedling Soaked under Low-temperature

[目的]进一步提高杨树造林成活率。[方法]对杨苗进行整株浸水、水温贮藏、延长休眠等技术处理,以推迟杨树发芽,及时补栽冬春造林已死亡的植株。[结果]造林成活率达99.9%,高于一般春季造林成活率6个百分点。[结论]杨树造林成活率大大提高,对进一步提高杨树造林数量及质量具有引导作用。

[Objective] The survival rate of poplar in the afforestation was further improved through the research.[Method] The technical treatment of whole poplar seedling-soaking,the water temperature in its storage and its dormancy-prolonging was adopted for the delay of the poplar sprouting,which could be re-planted timely in the afforestation when the poplar plant died in winter and spring.[Results] The technique could resulted in the survival rate of 99.9%,which was higher than 6% of normal survival rate in the afforestation in spring.[Conclusion] The survival rate of poplar-planting was greatly improved,which would further enhance the quantity and quality of poplar afforestation.
