摘要
科尔沁沙地土壤贫瘠,沙层较深,气候、自然条件差,人口稀少,仅靠人工治沙远远不能满足荒漠化治理的需要。在科尔沁沙地进行的钻孔杨树植干深栽造林试验表明:钻孔深度达到1.7m以下时,采用经过24h浸水处理的杨树植干造林成活率几乎达到100%,使用深孔钻造林的效率为180棵/h。
Keerqin sandy land is characterized by barren soil, thick sandy layer, poor natural conditions and sparse population, so artificial sand control alone is far from being able to meet the needs of desertification control. The poplar deep planting afforestation tests by means of drilling in Keerqin sandy land show that when hole depth reaches more than 1.7m, the survival rate of afforestation of poplar going through 24h immersion treatment can reach almost 100%, with deep hole afforestation efficiency up to 180 trees per hour.
