Abstract
The degradative kinetics of pesticides on tea plant surface are characterized by an initial rapid degradation which follows a first-order kinetics, then transferred to a more slower degradative rate. The degradative process mainly consists of photodegradation, evaporation, rainfall elution and growth dilution. The influencing parameters of these processes were investigated on tea plant. The predictive model of the initial concentration, photodegradation rate constant, evaporation rate constant, rainfall elution rate, growth dilution rate and the total degradative rate was discussed and verified in four locations situated in the range of 25°-30°N latitude, and acceptable results were obtained.
期刊介绍：
The Journal of Tea Science was established in August 1964, approved by the Publicity Department, CCCPC. Its title was inscribed by Zhu De, the chairman of CCCPC. It was discontinued during the Cultural Revolution in 1966, and it was reissued in August 1984, approved by the State Scientific and Technological Commission.Academicians Chen Zongmao and Liu Zhonghuaof the Chinese Academy of Engineering served as the directors of the editorial board. The Journal of Tea Science is managed by the China Association for Science and Technology,sponsored by the China Tea Science Society and the Tea Research Institute of the Chinese Academy of Agricultural Sciences, and edited and published by the editorial office of the Journal of Tea Science. It is the only one of Chinese core journals in the field of tea science that is included in the core library of the Chinese Science Citation Database.Its Domestic Unified Serial Number is CN 33-1115/S, its International Standard Serial Number is ISSN 1000-369X and its International publication name code is CODEN-CHKEF4. At present, the Journal of Tea Science is a bimonthly publication, published in the middle of the month, with a book size of 16.
