盛大互娱3917李海兵教授团队ACS AST:柱芳烃主客作用实现农药液滴的铺展传递
发布时间:2023-02-21 点击率:



近日,盛大互娱3917李海兵教授团队农药铺展传递领域取得重要性研究进展,相关成果以研究论文形式在美国化学会农业领域权威期刊ACS Agricultural Science & Technology发表封面论文,该论文第一作者为硕士生张会娟,通讯作者为盛大互娱3917李海兵教授。

粮食事关国运民生,粮食安全是国家安全的重要基础。中国始终把解决人民吃饭问题作为治国安邦的首要任务。然而,保障粮食安全与农药的使用脱离不开。李海兵教授团队在中国科协一带一路专项的支持下,长期与一带一路沿线国家搭建合作型智库网络体系,致力于提升绿色农药在农业中的利用率。其中,丁硫克百威作为农业杀虫剂可防治蔬菜、玉米、棉花、水稻、小麦等多种经济作物害虫,对蚜虫的防治效果尤为显著,使用广泛。但在喷洒施药时往往因作物叶表面超疏水导致农药弹跳、飞溅和漂移等,对环境和人类健康造成重要威胁。杀虫剂农药液滴在超疏水作物表面的保留是一个卡脖子壁垒,已经逐渐成为农药领域研究与开发的主流与方向。它对提高农用化学品的利用率、减少农药浪费和环境污染等具有非常重要的意义。

李海兵教授团队长期致力于研究基于主客自组装原理的超分子铺展剂,开发了可以促进农药液滴在疏水作物上铺展沉积的超分子铺展剂。近日,该团队在国家变革性技术关键科学问题重点研发计划《超铺展液滴调控技术用于高效农药利用的基础研究》(2021YFA0716702)的项目支持下,发现了杀虫剂丁硫克百威液滴与柱芳烃液滴在超疏水小麦上通过主客结合实现了共铺展。与空白对照相比,液滴的铺展保留提62%,实现了农药的减量增效。本研究为延长农药保留期和减少农药损失提供了一种新策略。该团队接下来将继续进行超铺展技术的优化与推广。

项目支持:国家重点研究计划(2021YFA0716702)、国家自然科学基金(22071074、21772055)、高等学校学科创新引智计划(B17019)。
