| 摘 要： | 采用深穴整地、穴底植苗、草灌覆盖的造林新方法，可有效地保持土壤水分，土壤含水率超过了水平梯田整地常规植苗造林的林地；造林2a后落叶松保存率达95．6％，常规造林仅为52．4％，对提高干旱地区落叶松造林成活率有显著作用；落叶松幼树高度和当年生长量均比常规植苗造林的高。

| Abstract: | Conducting new planting method,such as site preparations in a bottomless pit,stock planting at the bottom of the planting holes,grass and shrub coverage,can conserve the soil moisture effectively.Soil moisture exceeds forest land of normal tree planting with level terrace site preparations;preservation rate of larch reaches 95.6% after 2 years' afforestation.Preservation rate of conventional afforestation of larch is only 52.4%.This new method have significant effects on improving survival rate of larch in arid area.Tree height of sapling of larch and current annual increment are all higher than that of normal tree planting. |
