昭平县茶毛发病的发生特点与防控对策
Occurrence characteristics and control strategies of horse hair blight(Marasmius equicrinis)in Zhaoping County
摘要
Abstract
To understand the occurrence characteristics and influencing factors of horse hair blight(Marasmius equicrinis)in Zhaoping County,Guangxi Province,a field survey was conducted across 15 typical tea plantation sample plots.The occurrence characteristics of tea hair diseases were recorded using the field visual assessment method.Combined with the local climate characteristics such as temperature and precipitation,the tea garden habitat environment,and the age of the tea trees,the influencing factors of tea hair diseases were analyzed.The results showed that the disease was observed in 6 sample plots,accounting for 40%of the total surveyed plots.The overall degree of damage caused by the tea aphid in tea gardens is at a moderate level,with older tea plantations(≥40 years),poorly managed,and highly shaded plantations being more severely affected.Analysis of potential factors influencing the occurrence of horse hair blight in tea gardens mainly included climatic conditions(rainy and humid climate),tea plant age(aged tea plants),shading levels in tea gardens,and soil environment(soil acidification).Based on the above findings,a control strategy is proposed,which emphasizes agricultural practices as the foundation,focuses on ecological regulation and biological control,and is supplemented by chemical pesticide application when necessary.Specific measures include strengthening garden cleaning,pruning,and balanced fertilization to improve ventilation and light penetration;establishing an ecological regulation system in tea gardens with priority given to the application of biocontrol agents such as Bacillus spp.to control the disease;and when the disease is severe and biological control is insufficient,scientifically selecting low-toxicity chemical fungicides such as bordeaux mixture,thiophanate-methyl,or tebuconazole for localized application.This study provides a reference for the research and control of horse hair blight.关键词
