摘　　要：为探明锌肥对花生叶片光合机构活性氧代谢和衰老的调控机制,通过大田和室内实验相结合的方法,研究锌肥(ZnSO_(4)·7H_(2)O)施用量对花生生长过程中衰老相关参数和产量的影响。结果表明,随着施锌量的增加,花生的叶绿素含量、净光合速率、硝酸还原酶活性、过氧化氢酶活性和产量呈现出先升高后降低的趋势,光呼吸速率、米勒反应和丙二醛含量先降低后升高。适当施用锌肥不仅可以促进活性氧的清除,而且可以抑制活性氧的产生,锌肥通过活性氧的产生和清除对花生衰老进行调控。To explore the regulatory mechanism of zinc fertilizer on active oxygen metabolism and senescence of peanut leaves,through field and indoor experiments,the effects of zinc fertilizer(ZnSO_(4)·7H_(2)O)application on senescence related parameters and yield of peanut during growth were studied.The results showed that with the increase of zinc application,the chlorophyll content,net photosynthetic rate,nitrate reductase activity,catalase activity and yield showed a trend of first increasing and then decreasing,and the photorespiration rate,Mehler reaction and malondialdehyde content showed a trend of first decreasing and then increasing.Proper application of zinc fertilizer can not only promote the removal of active oxygen,but also inhibit the production of active oxygen.Zinc fertilizer regulates peanut senescence through production and elimination of active oxygen.
