摘　　要：为客观反映粮食作物病虫害防控的成效和贡献率,2022年全国农业技术推广服务中心组织河北、吉林、河南和云南4省植保体系开展玉米重大病虫防控植保贡献率评价工作.通过统一试验方案,设置严格综防区、统防统治区、农民自防区和完全不防区,采用多点测产,经科学评估,2022年全国玉米病虫害(不包括草害和鼠害)防控植保贡献率为18.74%.统计分析表明,严格防控情况下,植保贡献率比农户自防高8.44%;统防统治条件下,植保贡献率也比农户自防高4.26%.玉米“虫口夺粮”仍有较大潜力可挖.To evaluate the result of the prevention and control of major maize diseases and pests,and objectively reflect the effectiveness and contribution rate of disease and pest control,in 2022,the National Agri-Tech Extension and Service Center organized the plant protection system of Hebei,Jiling,Henan and Yunnan to uniformly setting strict prevention and control areas,unified prevention and control areas,farmers'self-defense areas and non-control areas,using the method of multi-point test sampling.After scientific evaluation,the contribution rate of plant protection on national maize pests and diseases(excluding weeds and rodents)in 2022 was 18.74%.Statistical analysis shows that under strict prevention and control,the contribution rate of plant protection is 8.44% higher than that of farmers'self-prevention;under the condition of unified prevention and control,the contribution rate of plant protection is also 4.26% higher than that of farmers'self-prevention.The plant protection contribution still has great potential.
