近日从山东农业大学植保学院获悉,由该院牵头完成的玉米重大病虫害发生机制及防控关键技术研究与示范项目取得重大成果。据介绍,病虫草害一直是影响我国玉米产量和品质的重要因素,每年导致玉米减产15%~20%,给我国玉米生产、粮食安全和农民增收造成了威胁。因为全球气候变暖、种植结构和栽培模式改变等因素的影响,玉米病虫草害的种类和发生规律也发生了明显变化。粗缩病、灰飞虱、穗部害虫等常年处于高发状态,顶腐病、二点委夜蛾等新病虫不断出现,原来的次要病虫褐斑病、瘤黑粉病、蓟马等危害上升,给玉米病虫
Recently learned from the Shandong Agricultural University Plant Protection Institute, led by the hospital to complete the major maize pests and diseases mechanism and prevention and control of key technologies research and demonstration projects have made significant achievements. According to reports, pests, weeds and weeds have been an important factor affecting the yield and quality of maize in China. Each year, it leads to a 15% to 20% reduction in corn production. This has posed a threat to China’s corn production, food security and peasants’ income growth. Because of the global warming, planting structure and cultivation mode changes and other factors, the types and occurrence of maize pests and diseases also occurred significant changes. Nodules such as Rough, Slug, and Spike pests are in high status all the year round. Top pests such as Newcastle disease (SSW) And other hazards rise, to corn pests
