摘要
为了应对冬季冻害问题,湖北柑桔生产中温室大棚栽培得到了一定程度推广和应用,但大棚栽培柑桔煤烟病发生日趋严重.通过连续 3 年的观察和试验,发现温室大棚柑桔煤烟病的发生、发展与栽培管理、通风透光条件、棚内温湿度及蚜虫、吹绵蚧、黑刺粉虱等虫害发生等有密切关系,在柑桔煤烟病发生初期开始整株喷洒针对蚜虫、吹绵蚧、黑刺粉虱的杀虫剂与杀菌剂混剂两次的防治效果可达 80%以上,采用高压水枪冲洗树冠可收到"立竿见影"的效果但易复发.提出了采用农业防治、生物防治、适时运用针对性杀虫剂混合广谱性杀菌剂防治的综合防控方案,在生产中推广应用实现了对柑桔煤烟病的有效控制.
Abstract
To deal with the issue of winter freezing injuries,the protected cultivation of citrus has been widely promoted and applied in Hubei.However,the occurrence of citrus sooty mold disease is becoming more and more severe.Through three years of continuous observation and experiment,it was found that the occurrence and development of citrus sooty mold disease was closely related to cultivation management,ventilation,lighting conditions,indoor temperature and humidity,and the incidence of pests such as aphids,mealybugs,and black scale insects.The control efficiency could reach over 80%by spraying a mixture of insecticides and fungicides targeting aphids,mealybugs,and black scale insects at the initial stage of citrus sooty mold disease occurrence.High-pressure water gun could be employed to clean the tree canopy with'immediate control effects',but the efficiency was very limited because of easy recurrence of disease.A comprehensive control measure involving agricultural control,biological control,and timely use of targeted insecticides mixed with broad-spectrum fungicides was proposed.The promotion and application of this measure in production achieved effective control of citrus sooty mold disease.
