摘要
为提高沙地人工造林成活率,开展了不同的整地方式、苗木类型、保水措施对冀北山区沙地人工造林成活率影响的试验。结果表明:在冀北山区沙地植被恢复中采用樟子松容器苗造林,提前开沟整地,栽植后覆膜保水效果明显,成活率较高。结合分析结果,构建了成活率与苗木类型、整地方式、保水措施等三项的回归模型,有效解释成活率的88.9%变化原因。
In order to improve the survival rate of artificial afforestation in sandy land,the experiments on the effects of different land preparation methods,seedling types and water conservation measures on the survival rate of artificial afforestation in sandy land in northern Hebei mountainous area were carried out.The results showed as follows:the container seedlings afforestation of Pinus sylvestris var.mongolica was used in the vegetation restoration in sandy land of the northern Hebei mountainous area,and the trenching and land preparation were carried out in advance;after planting,the water retention effect of film mulching was obvious and the survival rate was high.Combined with the analysis results,a regression model of survival rate with seedling type,land preparation method and water conservation measures was constructed,which effectively explained the reasons for 88.9%change in survival rate..
