Study on the Inhibition Effect of “Fly Catkins One Cut Clean” on Willow Catkins

摘要: 郑州市坪安园林植保技术研究所生产的“飞絮一插净”对杨树和柳树的花絮形成有较好的控制效果，能有效达到控制飞絮的目的，且试验药剂对树体安全、无毒副作用。使用抑制剂控制杨树及柳树飞絮方法操作性强，简便易行，成本相对较低，效果显著。在中原地区，每年5月上中旬，使用“飞絮一插净”抑制杨柳树花芽形成，是一条切实可行的方法。

Abstract: The “fly catkins one cut clean” produced by Zhengzhou Ping’an Garden Plant Protection Technology Research Institute has a good control effect on the formation of poplar and willow flocculus, and can effectively achieve the purpose of controlling the flying flocs, and the test chemicals are safe, non-toxic and side effects on trees. The control method of poplar and willow catkins with inhibitors is easy to operate, low cost and remarkable effect. In the Central Plains area, it is a feasible method to control the flower bud formation of willow trees by using the “fly catkins one cut clean” in the first and middle of May every year.
