对华北落叶松切根换床苗与留床苗的根系与造林效果研究表明,换床苗的根系发达,吸收土壤中水分、养分能力强,造林效果好。用换床苗造林是提高造林成活率和幼林生长的有效途径之一,在太行山绿化中值得推广。 Roots and afforestation effects of the cuttings and bed seedlings of Larix principis-rupprechtii were studied. The results showed that the root system of bed-replanting seedlings was well developed, absorbing water and nutrients from the soil and good afforestation effect. Afforestation with seedling transplanting is one of the effective ways to improve the survival rate of afforestation and the growth of young forests. It is worth promoting in the afforestation of Taihang Mountains.
