摘要
利用刺槐萌蘖力强的特性,对刺槐无性系种子园老龄化后的树体进行截干试验,促使其萌蘖形成新的树冠,并进行整形修剪,结果表明:老龄母树截干矮化,效果良好,达到预期目标。解决了原母树树体高大釆种困难的问题,为提高刺槐种子园老龄化后种子产量和质量进行了有益的探索。
Using the characteristics of vigor germination for Robinia pseudoacacia seedlings,the truncation of Robinia pseudoacacia was conducted.The new crown was formed and pruned,which solves the shortcomings of inconveniencing collecting the seeds from the mother tree,and makes a beneficial exploration to improve the seed yield and quality after aging of Robinia pseudoacaciain seed orchard.
