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.
Abstract:
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.
