农药在田间作物及生态环境中的降解动力学过程的研究一直是环保研究领域的一个重要课题,只有明确农药降解机制才能为有效地控制农药残留和农药污染提供理论依据。在田间实验条件下,农药在茶树新梢叶片上的消解受若干因素的影响,如阳光辐射所引起的光分解,茶树生长对农药含量的稀释,雨水的冲洗和水解,气温的变化引起的热解和蒸发及茶树体内酶活性引起的催化降解等都是农药残留降解的可能途径。通常所测定的农药在茶树叶片上的降解就是诸多因素综合作用的结果。降解只是广义地表示农药的消失,其中包括严格的 Pesticides in the field of crop and ecological degradation kinetics process has been an important issue in the field of environmental protection studies, only a clear mechanism of pesticide degradation in order to effectively control pesticide residues and pesticide contamination provide a theoretical basis. Under field experiment conditions, the digestion of pesticides on shoot tip of tea tree is affected by several factors, such as photodegradation caused by solar radiation, dilution of pesticide content by tea plant growth, irrigation and hydrolysis of rainwater, change of temperature Solution and evaporation, and the catalytic degradation caused by enzyme activity in tea plant are all possible ways of pesticide residue degradation. The commonly measured pesticide degradation on tea leaves is the result of a combination of many factors. Degradation is only a general indication of the disappearance of pesticides, including strict
