干旱半干旱过渡区柠条造林技术试验研究

Experiment Research on Afforestation Technology of Caragana korshinskii in Arid and Semi-arid Transition Region

2015~2016年在调查基础上对柠条造林进行了试验研究,柠条植苗造林时机为春季树液流动后和秋季停止生长树叶皮层脱落后;直播造林受土壤含水量、温度及直播深度的影响出苗率变化大,在干旱区宜林沙荒地柠条直播造林造林时,在气温稳定回升到10℃以上,土壤含水量大于8%后可进行直播造林,填补植苗春夏不能造林的空隙,试验结果显示植苗结合直播补植当年可达到国家造林标准。

The article studied the afforestation technology of Caragana korshinskii on the bases of survey between 2015-2016, the appropriate time of afforestation is spring sap flow and autumn leaves after falling off cortex stop growing. Forestation is affected by soil moisture content, temperature and depth of live emergence rate change is big, when the temperatures climb above 10 ℃, soil moisture content is more than 8% then direct seeding forestation can be conducted in arid areas which can fill the gap in spring and summer seeding afforestation.
