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.

农药对茶树的影响及茶树鲜叶中农药残留的预测

农药在茶树表面的降解动力学表现为先快速降解后一级降解，然后转入较慢的降解速率。降解过程主要包括光降解、蒸发、降雨洗脱和生长稀释。在茶树上研究了这些过程的影响参数。在北纬25°~ 30°范围内的4个地点对初始浓度、光降解速率常数、蒸发速率常数、降雨洗脱速率、生长稀释速率和总降解速率的预测模型进行了讨论和验证，得到了可接受的结果。

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.
