| 摘 要： | 近年我国农田有害生物暴发性灾害发生频率呈不断上升趋势,已成为制约农业高产、优质、高效益持续发展的主导因素之一。迁飞性害虫大量迁入降落、生态环境的破坏、生物多样性的降低、自然因素的不正常变化、预测和防治技术的滞后以及有害生物的入侵是导致农田有害生物暴发性害灾频发的因素。改进农田有害生物灾害预测技术、保护和改良农田生态系统、提高控制农田有害生物灾害的技术水平、加强植物检疫是控制农田有害生物暴发性灾害的途径。

| Abstract: | The outbreak frequencies of biological disasters in farmland increased in recent years, they has became one of the major constraints which restricting the productivity, quality and efficiency of agriculture. Entering of large numbers of migratory pest insects, destroyed ecological environments, decreases of bio-diversity, abnormity of natural environments, the delayed responses of forecasting and prevention and invasion of alien pests were the major factors contributing to the frequent outbreaks of biological disasters in farmland. Improving forecasting techniques for farmland pests, protecting ecological environments, enhancing controlling techniques, and strengthening plant quarantine should be the key measures to prevent the frequent outbreaks of biological disasters in farmland. |
