Abstract:

Jianghuai region is one of the main grain producing areas in China,which is rich in temperature, light and water resources. The region is located in the northern and southern climate transition zone, in which the types of diseases, insect pests and weeds are different. Therefore, it is very important to explore the green prevention and control technology of diseases, insect pests and weeds to ensure grain safety production. There are various crop planting patterns in the Jianghuai region, in which the rice-wheat rotation cropping system is the most important one. According to the occurrence regularity and damage characteristics of the main targets pests and weeds in rice-wheat rotation system, the agricultural ecological technology and comprehensive application technology of green inputs, pesticides and machinery were integrated to form the green prevention and control technology for diseases, insect pests and weeds. This technology has been successfully demonstrated and applied in Jianghuai region in recent years. The present study introduced this technology mode in detail in order to provide technical support for sustainable development of regional grain production.

Key words: rice-wheat rotation cropping system, diseases,pests and weeds, green prevention and control technology, Jianghuai region

摘要：

江淮地区温光水资源丰富,是我国重要的粮食主产区之一。该地区地处南北气候过度地带,病虫草害类型复杂,病虫草害绿色防控是确保粮食安全生产的重要保障措施。江淮地区作物周年种植,模式多样,其中以稻-麦轮作种植模式为主。本研究根据安徽粮丰项目试验示范成果,结合江淮稻-麦周年生产实际,针对稻-麦周年生长不同生育期主要靶标病虫草害发生规律和为害特点,集成了以农业生态技术措施为前提、绿色防控投入品综合应用为基础、药械联用精准减量高效防控靶标生物技术为突破口的绿色防控技术模式,并成功示范推广。本文就该技术模式进行了详细介绍,以期为区域粮食绿色安全可持续生产提供技术支持。
