| 摘 要： | 樟子松自1975年在山西省北部半干旱风沙区引种栽植成功以来，造林翌春幼树大量死亡已成为造林屡屡失败的关键，究其原因，是幼树遭受生理干旱所致。1996年-1997年进行了造林当年不同越冬保护措施效果调查结果表明：幼树当年越冬采用地膜覆土法比单纯覆土法翌春保存率提高28.5%，每公顷成本节省921元。

| Abstract: | Pinus sylvestris var.mongolica has been successfully introduced and grownin semi arid wind sand area since 1975,however,if Pinus sylvestris var. mongolica trees afforest,most trees usually die of physiologic drought next spring,this has become the key problem in Pinus sylvestris var. mongolica silviculture.From 1996 to 1997,we studied the effect of protection against winter freeze damage on Pinus sylvestris var. mongolica first year plantation,the results showed that the survival rate of Pinus sylvestrisvar.mongolica seedlings covered with thin plastic film and soil increased by 28 5% over those covered with soil,and the cost save 921 yuan per hectare. |
