摘要
Centre for Chemical Application Technology(CCAT)of China Agricultural University(CAU),is one of the important parts of the National Key Laboratory of Chemicals Application of the Ministry of Agriculture.Cooperating with Hohenheim University and Julius Kuhn Institute(JKI)in Germany since 1985,CCAT of CAU was established with the help of Hohenheim University and Application Techniques Division of JKI with some key apparatus and equipment,and also financially supports from the China National'211'and'985'projects.Application techniques in practice highly influence the chemicals utilization,including the biological efficacy of chemicals,the residues of chemicals,and harms of chemicals to water bodies,biotopes and neighboring crops.Application technique is the key to chemicals manageability as well as user protection.
