前言一般认为,裸根苗造林应在春季,当苗木仍旧处于休眠状态时进行Toumey和Korstian(1942)指出:“无例外地,造林的最佳时节是在造林苗木的新芽开始生长的前两周或更早一些的时候”。如果造林计划的规模允许,造林工作都应照此进行。造林成功的两个基本因素是:(1)造林苗木应具有能够适应其定植地的生境环境的生理能力;(2)在生境因子适合于苗木存活和生
Foreword It is generally believed that bare root seedling afforestation should be carried out in the spring when seedlings are still dormant. Toumey and Korstian (1942) pointed out: “Without exception, the best time for afforestation is in the first two weeks after the shoots of afforestation seedlings begin to grow Or earlier ”. Afforestation should be done if the size of the afforestation plan is allowed. The two basic factors for afforestation success are: (1) afforestation seedlings should have the physiological ability to adapt to the habitat environment in which they are planted; (2) when habitat factors are suitable for seedling survival and survival
