河北省梨树主要病虫害发生演变与综合防控技术
Occurrence,Evolution and Integrated Control Techniques of Major Diseases and Pests in Pear Trees in Hebei Province
摘要
Abstract
As a core production area for pears in China,the occurrence dynamics and evolutionary patterns of diseases and pests in Hebei Province directly impact the quality improvement and efficiency enhancement of the pear industry.This paper systematically analyzes the historical changes,occurrence characteristics and key disas-ter-inducing factors of major diseases and pests in pear orchards.It reveals the driving effects of factors such as cultivation pattern transformation,variety structure renewal,climate change and irrational pesticide applica-tion on the succession of pest populations.Several prominent issues within the existing control system are identi-fied,including significant fluctuations in pest population dynamics,growing pesticide resistance of pests,and insufficient awareness of the prevention and control of certain diseases.An integrated pest management strategy oriented towards the sustainable development of the industry is proposed,providing a theoretical basis and tech-nical support for safe production and green control of diseases and pests in the pear industry of Hebei Province.关键词
