This paper takes Platanus acerifolia,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 Platanus acerifolia were 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 Platanus acerifolia.It has a good control effect and can be applied in production.
