摘要：

为解决木棉果絮植源性污染问题，在木棉末花期开展“抑花一号”药剂的浓度处理试验，研究其对木棉飞絮和植株的影响。结果表明，在木棉末花期后施用“抑花一号”药剂对促进木棉败育落果的效果极显著，药剂浓度越高效果越明显。3 a跟踪调查发现，施用“抑花一号”后样株出现不同程度的开裂、流胶、萌枝异常、枯枝、树势削弱等情况，随时间推移，翌年成花受抑制甚至不能完成花芽分化，浓度越高此类药害表现越明显。权衡效果和药害，治理木棉飞絮如果只使用“抑花一号”化学药剂，推荐使用浓度0.5%+剂量25 mg/cm或浓度1%+剂量12.5 mg/cm。

Abstract:

In order to solve the inconvenience caused by the flying-catkins of kapok, different concentrations of “Yihua No.1” were carried out at the final flowering stage of kapok to study its influence on the formation and development of kapok fruit. Results showed that the application of “Yihua No.1” at the last flowering stage of kapok had a very significant effect on promoting abortion and fruit drop of kapok, and the higher the concentration of the drug, the more obvious the effect. A 3-year follow-up investigation showed that after the application of “Yihua No.1”, the sample plants appeared different degrees of trunk cracking, secreting gum, abnormal sprouting, dead branches, and weakened tree potential and so on. By the next year, the flower formation was inhibited, and some of them could not even complete flower bud differentiation. The higher the concentration, the more obvious such damage. Considering the effect of “Yihua No.1” and its adverse effects on trees, 0.5% concentration with 25 mg/cm, or 1% concentration with 12.5 mg/cm were recommended to use in production.
