由于樟子松苗木出圃期间,苗木活力容易降低,人工造林难以成功,从而影响了这一优良树种大量发展.为解决这一问题,我们对樟子松(2-1)型苗木越冬贮藏方法和越冬期间苗木水势、可溶性糖和淀粉含量的动态变化规律,以及越冬后造林成活率和初期生长量等进行了试验研究,从而筛选出樟了松苗木以原床覆土越冬、早春随起随栽造林效果最佳,只要在出圃期间保护好根系和顶芽,在大兴安岭适生立地条件下人工造林是完全可以成功的.
As the seedlings of Pinus sylvestris var.mongolica are easy to be reduced during the nursery period, the seedling vigor is easily reduced and the success of artificial afforestation is difficult, which will affect the development of this fine tree species.In order to solve this problem, The dynamic changes of seedling water potential, soluble sugar and starch content during winter, and the afforestation survival rate and initial growth after overwintering were studied in order to screen out pine seedlings to cover the soil overwintering, The effect is best. As long as the roots and the top buds are protected during the nursery, plantation in the setting of the Greater Khingan Range is completely successful.
