| 摘 要： | 毛乌素沙区土壤以风沙土为主,严重地影响樟子松造林的效果。因此栽植坑的大小及其坑内的土壤类型在风沙区樟子松造林中显得尤为重要。该研究进行大坑换土与小坑不换土的对比试验,测定黄绵土和风沙土的理化性质,对比樟子松的保存状况和生长状况。结果表明：黄绵土的理化性质比风沙土的理化性质更好;大坑换土处理的樟子松保存率和生长量比小坑不换土的好。因此,进行大坑栽植和把坑内的风沙土换作黄绵土处理对樟子松的保存率和生长量具有明显的促进作用,大坑换土是毛乌素沙区樟子松造林的一项有效的造林技术。 |
| 关 键 词： | 大坑 换土 樟子松 生长状况 毛乌素沙区 |

| Abstract: | Sandy soil which seriously influences the planting effect of Pinus sylvestris L.var.mongolica is the most main soil type in Mu Su Sandland.So the size of planting pit and the soil type in pit are very significant to planting of Pinus sylvestris L.var.mongolica.The comparing field experiments between changing soil in big pit and no changing soil in small pit were done.The physicochemical properties of loessial soil and sandy soil were determined.The station of survival and growth were comparing analyzed.The ... |
| Keywords: | Big pit changing soil Pinus sylvestris L.var.mongolica growth station Mu Us Sandland |
