叶面喷施骠马对张杂谷10号光合特性及产量构成的影响
Effects of Foliar Application of Fenoxaprop-p-ethyl on Photosynthetic Characteristics and Yield of'Zhang za 10'
摘要
Abstract
The security of application of Fenoxaprop-p-ethyl in foxtail millet was studied in the conditions of a wide vari-ety of herbicides but scarce available for foxtail millet .Field trial was carried out to study the effect of different levels of herbicides ,sprayed at the 3th or 4th leaf stages ,on photosynthetic characteristics ,chlorophyll fluorescence parame-ters and yield component of 'Zhang za 10' in experiment site of Shanxi Agricultural University .Results showed that after spraying herbicide ,photosynthetic pigment content ,the photosynthetic rate (Pn) ,stomatal conductance (Gs) , stomatal limitation value(Ls) ,Fv/Fm ,Fv/Fo ,Y(Ⅱ ) ,ETR and qP were varying decreased ;however ,the internal CO2 concentration (Ci) and NPQ were presented a tendency of opposite ,which displayed remarkable dose-response . The impact of herbicide on the photosynthetic characteristics of foxtail millet was more obvious at the initial of the treatment ,followed by a gradually slowing effect ,at the late of the treatment most of the indicators could be restored to the control level .Yield showed a trend of increasing at first and then decreasing .The above results suggested that a irreversible damage will be produced and reduce the yield of foxtail millet ,when the level of Fenoxaprop-p-ethyl exceed 900 ml·hm-2 .关键词
