清江流域是湖北省重要的优质柑橘产业带,柑橘种植面积达到1.3万hm2,年产20万t,产值近6亿元。受立体气候和多样生态环境影响,柑橘大实蝇、蚧壳虫、潜叶蛾等常见病虫害的危害时有发生,病虫果率居高不下,损失率在10%以上,且有逐年增加的趋势。调查近10年清江流域柑橘栽培管理模式和病虫害综合防治技术,分析清江流域柑橘病虫高发的原因,并提出相应防治对策。 Qingjiang River Basin is an important high-quality citrus industry in Hubei Province, citrus acreage reached 13,000 hm2, with an annual output of 200,000 t, the output value of nearly 600 million yuan. Affected by the three-dimensional climate and diverse ecological environment, the common pests and diseases of citrus fruit fly, scale insects, leaf moth and other pests and diseases often occur, the pest rate is high, the loss rate is above 10%, and there is a year-by-year increase trend. Investigate the citrus cultivation management mode and integrated pest management techniques in the Qingjiang River Basin in the recent 10 years, analyze the causes of the high incidence of citrus pests and diseases in the Qingjiang River Basin and put forward corresponding control measures.
