| 摘 要： | 容器苗作为主要的造林材料广泛用于林地更新和荒山的植被恢复, 但其造林成活率及生长表现常受杂草和土壤肥力的影响。指数施肥作为一种新型的容器苗培育方式, 将施肥量与植物指数生长期间的需肥量紧密结合, 并通过营养载荷在幼苗体内建立营养库, 从而降低了幼苗对种植地营养水平的依赖, 有利于提高幼苗的造林成活率。文中介绍了指数施肥的原理, 及其对苗期和种植后幼苗生长的影响, 旨在为容器苗指数施肥在我国的推广提供理论基础。

| Abstract: | Container seedlings were widely used to forest regeneration and vegetation restoration of bare mountain,and however,the survival rate and growth of outplanting seedlings were influenced by weeds and soil fertility.As a new culture method of container seedling,exponential fertilization takes an integrative account of the fertilizer applied and fertilizer needed during the exponential growth period of seedlings,and builds a nutrient reserve within seedlings via nutrient loading.In this way,seedlings will be l... |
