Construction of Comprehensive Control Technology System for Disastrous Fungal Diseases in Middle and Late Stages of Sugarcane in Low Latitude Plateau
Aiming at the control problem of disastrous fungal diseases in the middle and late stages of sugarcane in low latitude plateau,on the basis of finding out the types,pathogen groups,geographic distribution,damage loss and disaster characteristics of disastrous fungal diseases in the middle and late stages of sugarcane,this paper proposed to construct a comprehensive control technology system of sugarcane disastrous fungal diseases in the middle and late stages in low latitude plateau by using"early diagnosis and early warning,disease-resistant varieties,virus-free seedlings treated by hot water,agronomic regulation,unmanned aerial vehicle(UVA)flight control,biological agents and compound high-efficiency formula agents".Meanwhile,the key technical methods to realize the construction of comprehensive control system for sugarcane disastrous fungal diseases in the middle and late stage were systematically analyzed from the aspects of dynamics accurate monitoring technology of disease epidemic,mining and utilization technology of disease resistance genes,accurate evaluation technology of disease resistance,biological agents and compound high-efficiency formula agents and their application technology,and application technology of UVA flight control.From 2021 to 2022,a total of 323000 hm2(UVA flight control 67000 hm2)was popularized and applied,which saved 3.88 million tons of cane loss,increased 497 kilotons of sucrose,increased sales by 4.209 billion yuan,increased profits by 1.324 billion yuan and increased taxes by 199 million yuan.The economic,social and ecological benefits are remarkable,which provide technical support for the sustainable and high-quality development,loss reduction and efficiency improvement of sugar industry in low latitude plateau,and makes a significant contribution to the economic development of frontier ethnic groups,the increase of farmers'income and the revitalization of rural areas.
