不同药剂组合防治二球悬铃木果毛污染的研究

Study on the Prevention and Treatment of Fruit Hair Pollution of Platanus acerifolia Treated by Different Combination of Medicament

以河南职业技术学院院内道路两旁的行道树二球悬铃木(Platanusacerifolia)为研究对象,在设计不同化学药剂组合配比的基础上,通过树冠喷洒和树干注射等方式研究对二球悬铃木球果的影响,从而为其球果果毛污染的防治提供帮助。结果表明,在药剂基本试验浓度均为100 mg/L条件下,树冠喷洒和树干注射施药方式均可起到防治效果,其中树冠喷洒和化学试剂组合乙烯利︰赤霉素︰乙硫氨酸=1︰3︰1措施对二球悬铃木球果有显著的抑制球果生长和促进球果脱落的作用,起到了良好的防治效果,可在生产上推广应用。

This paper takes Platanusacerifolia,a street tree on both sides of the road in Henan Polytechni,as the research object.On the basis of the design of different chemical combinations,the effects of tree crown spraying and trunk injection on the cone of Platanusacerifoliawere studied,so as to provide help for the prevention and control of the cone hair pollution.The results showed that under the condition of the basic test concentration of 100 mg/L,Canopy spraying and trunk injection can both play a controlling role.Among them,canopy spraying and chemical reagent combination ethephon:gibberellin:ethionine=1:3:1 measures significantly inhibited cone growth and promoted cone shedding of Platanusacerifolia.It has a good control effect and can be applied in production.
