水稻生态系统现场学术交流会于1984年10月在广州举行。会议受中国学会委托,由中山大学生物系和北京大学生物系主持,与会代表37人。会议根据水稻病虫害的综合防治理论、技术体系和新途径等问题展开了热烈讨论。中山大学蒲蛰龙教授提出:从稻田生态系统着眼,以农业防治为基础贯彻生物防治的各项措施,协调使用农药,把主要害虫控制在经济损失许可范围内的综合防治原则。他们研究了稻田主要害虫和益虫的相关数量动态,用血清学方法搞清了捕食和被捕食昆虫的关系,并对重要害虫诹得了27个世代的生命表资料,经过生态数学的研究,不但在理论上为综合防治提供了
Rice ecosystem on-site academic exchange was held in Guangzhou in October 1984. Entrusted by the Chinese Society, the conference was hosted by the Department of Biology, Sun Yat-sen University and the Department of Biology, Peking University, with 37 delegates. The meeting launched a lively discussion based on the comprehensive prevention and control of rice diseases and insect pests, technical systems and new ways. Professor Pu Zhechong from Sun Yat-sen University proposed: From the perspective of paddy field ecosystem, all measures of biological control should be implemented on the basis of agricultural control, coordinate the use of pesticides, and control the major pests within the limits of economic loss. They studied the dynamics of the relative quantities of the major pests and beneficial insects in the paddy fields, clarified the relationship between predators and prey insects by serological methods, and obtained life-table data of 27 generations of important pests. After studying ecological mathematics, Theoretically provided for comprehensive prevention and control
