Application Status, Problems And Countermeasures Of Green Prevention And Control Technology Of Citrus Pests And Diseases In Gangnan District Of Guigang City, Guangxi

Taking the Guangxi citrus main producing area-Gangnan as an example,the thesis makes a comprehensive analysis and research on the application status,capital investment and technical training of Citrus green control in this area,so as to provide scientific basis for the application and popularization of the green control technology of Citrus diseases and pests in Gangnan and Guangxi.In recent years,the agricultural sector(Plant Protection Station)of Gangnan has vigorously promoted green control technology in the prevention and control of Citrus Diseases and insect pests,and achieved initial results.In 2017,the application area of Citrus pest control technology was 2271 ha,accounting for 68.3%of the total planting area of citrus.The survey found that 80%of citrus growers used green control technology to control citrus pests and diseases to a varying degree in a year.After the using of green control technology,the orchard reduces the use of chemical pesticides 2-5 times a year,saving about 30 yuan per mu,and the citrus growers are satisfied with the green control;technology,which has produced better economic,ecological and social benefits.At the same time,the popularization and application of green prevention and control technology for Citrus.Diseases and insect pests still exists some problems.For instance,the farmers can not clearly understand the green prevention and control technology;the government doesn’t pay enough attention to it;the insufficient promotion of it;the un sound promotion system of it;the lack of the professional service organization of it,cause the undesired degree of propogation intensity of green prevention and control technology.The green prevention and control technology of citrus pests and diseases has not been fully promoted.In view of these existing problems,this paper puts forward the corresponding countermeasures from seven aspects:1.strengthening leadership,forming a work force;2.increasing publicity,changing the concept of farmers;3.strengthening efforts,accelerating the development of moderate scale management;4.strengthening demonstration,promoting technology popularization on a point to area;5.integration of resources and increasing technical subsidies 6.to strengthen the integration of technology and increase the investment in research and development of green prevention and control technology;7.adhere to the two sticks to promote green prevention and control and professional rule of prevention and control to go hand in hand.This paper also discusses the application of green prevention and control technology in different crops,how green prevention and control technology serves agricultural modernization,and how to solve the bottleneck which affects the application and popularization of green control technology.
