综述了辽宁省春玉米区主要病虫害综合防治技术体系的发展过程 ,介绍了不同发展时期玉米病虫害的综合防治策略和模式 ,评述了各时期综合防治技术体系的特点 ,认为辽宁省春玉米区的综合防治技术体系经济有效、实用性强 ,与社会发展环境相协调 ;并针对当前玉米生产上出现的次要病虫害与原来被控制的病虫害上升为主要病虫害 ,病虫害为害加重 ,病虫害灾变异常爆发时缺乏有效的应急防治措施等问题 ,从玉米生产可持续发展的角度 ,提出了加强主要病虫害中长期预警技术研究 ,增强自然控制力量 ,监测病原菌生理分化和潜在危险性病虫害发展动态的治理对策。
The development of comprehensive pest control technology system in spring maize area of Liaoning Province was reviewed. The integrated control strategies and patterns of maize pests and diseases in different development stages were introduced. The characteristics of comprehensive control technology system in each period were reviewed. The prevention and control technology system is economical and effective, practical and coordinated with the social development environment. In view of the current emergence of minor diseases and pests in maize production and the original control of pests and diseases as the main pests and diseases, the pests and diseases are aggravated, and pests and diseases are abnormally erupted. From the perspective of sustainable development of maize production, the paper put forward some countermeasures to strengthen the research on long-term early warning technology of major pests and diseases, enhance the natural control power, monitor the physiological differentiation of pathogenic bacteria and the development of potentially dangerous pests and diseases.
