建国三十七年来,我省小麦病虫害的发生大致经历了三个阶段。即五十至六十年代的多种病虫轻微发生,少数病虫严重危害阶段;七十年代多种病虫剧烈变化阶段和八十年代多种病虫稳定,少数病虫更趋严重的阶段。纵观建国三十七年来我省小麦病虫发生演变和消长历史,引起发生演变的主导因素是耕作制度、水肥条件、作物内在的抗逆性等麦田基本生态因素和防治技术与实施等因素,而影响主要病虫害年际间发生程度的主要是气候及病、虫源等。根据我省今后五至十年麦田生态系统的变化趋势和防治技术水平的提高等因素的分析,
Thirty-seven years since the founding of our province, the occurrence of wheat pests and diseases generally experienced three stages. That is, a small number of pests occurred in the 1950s and 1960s, and a few pests were seriously endangered. In the seventies, there were a large number of pest and disease stages and many pests in the 1980s. Some pest and disease became more serious . Throughout the thirty-seven years since the founding of our province wheat pest evolution and the history of the growth and decline, the main factors that led to the evolution of the farming system, water and fertilizer conditions, inherent stress resistance of wheat and other basic ecological factors and prevention and control technology and implementation of such factors, Affected the main pests and diseases occurred in the inter-annual degree of climate and disease, insect sources. According to the analysis of the changing trend of the wheat field ecosystem in the province in the next five to ten years and the improvement of prevention and control technology,
