| 摘 要： | 对樟子松进行切根育苗试验，结果表明，机械切根苗苗木质量优于移植苗和留床苗。切根２０ｃｍ的苗高、地径分别比移植苗高９４ｃｍ和粗０２ｃｍ，大于１ｍｍ的侧根数量，平均比移植苗多１１８条，比留床苗多１０条。机械切根可使２年生樟子松产苗量，比人工移植提高２４２９％～３７１４％，每公顷增加收入１５２８５～３０１１１元。

| Abstract: | Cutting root is a measure to insure good quality seedling during seedling cultivation. In this paper, experiment of Mongolian scotch pine indicates that quality of root cutted seedlings is better than those of transplant and non transplant. The mean height and basal diameter of root cutted plants had an increment of 9 4 cm and 0 2 cm respectively than those of transplants in average. Root cutted seedling had 11 8 more bilateral roots bigger than 1 mm than that of the transplant and 10 than that of the non transplant in average. Moreover,this measurement resulted in 24 29%-37 14% increment of two year old seedling production than transplant,raising income of 15 285-30 111 Chinese yuan per hactare. |
