木棉树激素注射抑絮试验初报

Flying-Catkin Inhibition of Bombax malabaricum by Hormone Injection

木棉树果实爆果形成飞絮,对道路交通安全及生态环境带来一定的负面影响。通过注射生长激素"抑花一号"对木棉树抑絮进行了试验研究。结果表明:注射生物制剂,可有效防止或减少木棉树飞絮发生,实施效果有效率达到90%以上;最佳注射时间为末花期至子房掉落期。

The fruit of Bombax malabaricum bursts into a flying catkin,which has a certain negative impact on road traffic safety&ecological environment.The method of injecting growth-hormone on Bombax malabaricum‘Yihua No.1’was used to study the inhibition of Bombax malabaricum.Result shows that the injection of biological agents can effectively prevent or reduce the occurrence of flying catkin in Bombax malabaricum,and the effective rate of implementation is over 90%;the optimal injection time is from the last flowering period to the ovary drop period.
