我们知道,苗木失水不仅影响它的活力及造林成活率,而且影响造林后林木的生长状况。随着苗木水势、根系活力的下降,林木初期年高生长量也随之下降。许多相关分析研究表明,苗木水势、根系活力与造林后林木的初期年高生长量呈显著的线性关系。可见造林前苗木活力的高低对造林后苗木的生长状况的影响是非常深刻的。现通过对苗木的起苗相关的一系列问题的分析,阐述了如何提高造林苗木的成活率。
We know that seedling water loss not only affects its vitality and afforestation survival rate, but also affect the growth of afforestation trees. With the seedling water potential, root activity decreased, the growth rate of early age trees also will decline. Many related studies have shown that there is a significant linear relationship between seedling water potential and root vigor and the initial annual height growth of forest trees after afforestation. Shows the level of seedling before afforestation on the growth of seedlings after afforestation the impact is very profound. Now through the analysis of a series of problems related to seedling emergence of seedlings, this paper expounds how to improve the survival rate of seedlings.
