摘要
日本落叶松是我省东部山区的主要造林树种。本文通过日本落叶松苗木分级造林试验,表明选特级苗和Ⅰ级苗上山造林,可提高造林的成活率和保存率,加速幼林的高、径生长,确保幼林尽快郁闭成林。造林时,一定将苗木进行分级,混合苗造林不宜提倡。
Planting trial of seedling sorting to Larix kaempferi was conducted in eastern mountain rigion of Liaoning province,China. It showed that special grade and grade Ⅰ seedlings were the best to mountain planting, which could increase the survival and preserving rates, and accelerate saplings growth in height and diameter to attain a closed stand quickly.
