摘　　要：为客观反映病虫害防控工作对果树产量的保产效果和植保贡献率,2022年全国农业技术推广服务中心组织陕西、山西2省7县(市、区)植保站,以北方主要果树种类苹果、梨为研究对象,系统开展田间对比试验,进行了病虫害防控植保贡献率评价工作.据2省7县(市、区)多点试验测产数据,2022年北方苹果病虫害防控的植保贡献率为35.57%,其中,科学综防区、统防统治区和农民自防区的植保贡献率分别为50.91%, 37.27%和30.95%;梨病虫害防控的植保贡献率为44.38%,其中,科学综防区、统防统治区和农民自防区的植保贡献率分别为56.17%, 42.84%和36.09%.结果表明病虫害防控对果品保产植保贡献率巨大,同时仍有较大潜力可挖.In order to objectively reflect the effect of plant protection and the contribution rate of pest control on the yield of fruit trees, in 2022, National Agro-Tech Extension and Service Center(NATESC) organized plant protection stations in 7 counties(cities, districts) of Shaanxi and Shanxi provinces to systematically carry out field comparative tests and evaluate the plant protection contribution rate for apple and pear, which are the major fruit trees in the northern China as the research objects. According to the results of the yield measurement data of the multi-point experiment in seven counties(cities, districts) in two provinces, the plant protection contribution rate of apple pests control in the northern China in 2022 was 35.57%, of which the rate in the scientific comprehensive prevention area, the unified control area, and the farmers’ self-prevention area was 50.91%, 37.27%, and 30.95%, respectively. The plant protection contribution rate of pear pest control was 44.38%, of which the rate of scientific integrated control area, unified control area, and farmers’ self-control area was 56.17%, 42.84%, and 36.09%, respectively. The results showed that the prevention and control of pests contributed greatly to the fruit yield and plant protection contribution rate, and still has great potential.
