【摘要】 草原虫害防治是农业部较早大规模组织开展的防灾减灾工作之一。在长期的实践工作中,草原虫害防治始终坚持"预防为主,综合防治"的植保方针,逐步建立了"以生物防治为主,化学防治为辅"的技术路线。2002年起,全国畜牧总站在全国牧区组织开展了《草原虫害生物防控综合配套技术推广应用》项目。该项目的实施带动了全国的草原害虫防治,为草原可持续发展提供了技术支撑。本文以该项目的进展为基础,简要总结介绍了草原害虫防治的实施背景、开展情况及建设成果,包括以生态系统平衡原理为指导,对虫害监测预警、生物防控和施药技术等进行集成创新与组装配套,使草原害虫密度长期控制在经济阈值以下,实现草原生态系统平衡等。更多还原

【Abstract】 Control of Grassland insect pests is an example of important early disaster prevention and mitigation work by the Ministry of Agriculture,China.The grassland insect pest control policy was based on prevention first followed by integrated control.The long-term practice was to use biocontrol as the primary means of control with chemical control used in a complimentary role.The establishment of biocontrol techniques for insect pests has been undertaken by the China Animal Industry Station since 2002.Ecosystem balance was used as the main driver of policy in the program.Insect pest monitoring and early warning,biocontrol and pesticide application technology was utilized,and insect pest density maintained below the economic threshold level during this time.The achievements of the program have been recognized in the National Agricultural Harvest Awards.The background,progress and major achievements of the program are introduced with the aim of informing people about the current status of grassland insect pest control in China.更多还原
