刺槐(Robinia pseudo—acacia)是我省主要造林树种之一,为提高刺槐人工林的生长量,经几年研究已选育出一批增产效果显著的优良无性系。但是,只有研究出有效的无性繁殖方法,才能很好的推广。为此,我们在1985—1987年进行了刺槐细根段催芽育苗技术的研究.结果表明,平均发芽率77％,移植芽苗成活率89.6％。平均当年苗高1.25m,平均 Robinia pseudoacacia is one of the main afforestation species in our province. To improve the growth of Robinia pseudoacacia plantation, a number of excellent clones with significant yield increase have been bred in recent years. However, only effective method of asexual reproduction can be well popularized. For this reason, we conducted the research on germination and nursery of fine locust roots from 1985 to 1987. The results showed that the average germination rate was 77% and the survival rate of transplanted seedlings was 89.6%. The average annual height of 1.25m, average
