通过 10多年来造林工作实践 ,总结出针叶树造林有关如何利用苗木的问题。油松、樟子松造林一般采用 2年生移植苗造林 ,这将有利于提高造林成活率和幼树生长量 ;采用不合格苗造林 ,将显著降低一次性造林成活率 ;苗木在出圃前要灌足“三水”即解冻水、化冻水和起苗水 ,只有提高苗木的含水量 ,才能保证造林的成活率 ,苗木的含水率与造林的成活率呈正相关 ;在造林实践中 ,不可忽视苗木的保湿 ,应尽可能做到随起苗随运输 ,随栽植 ,缩短苗木在外裸露时间
After more than 10 years of afforestation practice, summed up the coniferous afforestation on how to use seedlings. Pinus tabulaeformis, Pinus sylvestris afforestation generally use 2-year-old seedling afforestation, which will help improve the survival rate of afforestation and sapling growth; use of substandard seedlings afforested, will significantly reduce the one-time afforestation survival rate; Enough “Sanshui” that thawed water, frozen water and seedling water, only by raising the water content of seedlings in order to ensure the survival rate of afforestation, seedling moisture content and afforestation survival rate was positively correlated; afforestation practice, can not be ignored in the seedlings Moisturizing, should be as much as possible with the seedling with the transport, with planting, shorten the nursery outside exposure time
