| 摘 要： | 对华北落叶松切根、换床苗与留床苗的根系与生长研究表明,切根苗的根系发达,吸收土壤中水分、养分能力强,造林效果好,在林区值得推广。每年可进行1次切根,早春土壤化冻达15 cm左右时即可作业,以切根深度10 cm、苗木密度230株/m2为宜。

| Abstract: | The study on the root system and growth of root-cut seedling,bed-changed seedling and bed-fixed seedling of Larix principis-rupprechtii was conducted.The result indicated that the root-cut seedling has strong root system and big capacity of absorbing soil water and nutrient and good afforestation effect.It can make root-cut 1 time every year and can conduct it when thawy soil depth reaches 15 cm in early spring.The root-cut depth of 10 cm and the seedling density of 230/m~2 were fitting. |
