摘要
樟子松幼苗从半湿润地区调运到干旱沙区栽植,在不同土壤类型下,其成活率、保存率、顶芽生长等都表现出差异性。经研究,樟子松幼苗在其原产地苗圃生长,各方面性状表现最优;在干旱沙区沙壤土、砂土上,表现尚可;而在干旱沙区盐碱地上,栽植成活率低,生长不良。
Seedings of Pinus sylvestris var.mongolica were transplanted from semimoist region onto different soils.It is different in survival percent and growth of the central bud,and so on.The appearances of the seedling on the origin soil are all the best;and better on clay and desert;but on saline-alkali soil the survival percent is low,and the growth bad.
