发展热带作物是我国国民经济计划的一项重要任务。建国以来,天然橡胶、剑麻、咖啡、热带水果等热带亚热带作物,品种增多,面积扩大,生态环境变化。病虫发生为害日益严重,防治方法还较保守,亟须研究优化防治对策。在综合治理〔IPM〕理论指导下,根据热带区域的生境以及人们经济活动等情况,实践体会,必须注重解决几个主要问题: 1.要更新观念,进一步提高对综合治理的重要性、迫切性的认识。彻底改变过去认为“治虫就是打药”、“有虫无虫打几遍”的旧观念,树立“预防为主,综合防治”的思想,提高综合治理的认识。
The development of tropical crops is an important task for our national economy plan. Since the founding of the People’s Republic of China, tropical and subtropical crops such as natural rubber, sisal, coffee and tropical fruits have increased in variety, expanded in area and changed in ecological environment. Pests and diseases are becoming more and more serious, and the methods of control are still more conservative. It is imperative to study and optimize the prevention and control measures. Under the guidance of the theory of comprehensive management (IPM), based on the habitats of tropical regions and the economic activities of people, we must pay attention to solving several major problems: 1. To update our concepts and further enhance the importance and urgency of comprehensive management Understanding. In the past, we thoroughly changed the old concept of “fighting pests and killing insects and fighting insects and fighting several times” and established the concept of “prevention as the mainstay and comprehensive prevention and control” to raise awareness of comprehensive management.
