摘　　要：近年来,随着我国农业的快速发展,全国植保体系建设逐步得到加强,植保工作为防灾保丰收、减灾保稳定做出了较大贡献.为科学地评估农业生产中的植保贡献率,本文通过田间试验对重庆地区的重要茄科经济作物——番茄Solanum lycopersicum L.进行了植保贡献率的测算.研究发现,科学的防治措施可以提高番茄病虫害防效12.36~25.08个百分点,植保贡献率可达54.84%.本研究有助于番茄植保贡献率评价体系的建设和全面掌握当地病虫害的发生与防控情况.With the rapid development of agricultural economy in China in inrecent years,the construction of a national plant protection system has been sped up,and plant protection has made great contributions to disaster prevention,bumper harvest and stability.In order to further scientifically evaluate the plant protection contribution rate of disease and pest control in agricultural production,the contribution rate of plant protection of tomato(Solanum lycopersicum L.),an important cash crop of the Solanaceae family,was measured in this paper through field trials.The results indicated that control measures,used scientifically,could improve the efficiency tomato disease and pest control by 12.36-25.08%,and the plant protection contribution rate was as high as 54.84%.This study potentially facilitates the construction of evaluation technology system of tomato plant protection contribution rate and helps to fully understand the occurrence and control of local diseases and pests.
