中文摘要:
      研究不同沼肥施用方式(沼液根施、喷施、涂干、随水滴灌)下的红枣光合特性及其水分利用效率变化。结果表明:不同沼肥施用方式下枣树叶片的叶绿素含量、叶面积指数以及净光合速率的变化趋势较为一致,均为沼液喷施>涂干>对照>滴施>根施;蒸腾速率和气孔导度日平均值为沼液滴施>喷施>对照>根施>涂干;胞间CO2浓度日平均值为沼液根施>滴施>对照>涂干>喷施,而气孔限制值日平均值则表现与其相反;水分利用效率日平均值为沼液涂干>喷施>对照>滴施>根施。沼肥应用效果以沼液喷施为最佳。
英文摘要:
      Study is made on photosynthetic characteristics and water use efficiency of Zizyphus Jujube under different application ways of biogas waste fertilizer(ex-root, spray, smearing, dropping). The results show that Chl content, LAI and Pn have similar variation tendency under different application ways of biogas waste fertilizer, and they show an order of spray application of liquid manure > smearing trunk > contrast with chemical fertilizer > dropping fertilization >ex-root fertilization. The daily average values of Tr and Gs show dropping fertilization of liquid manure > spray application > contrast with chemical fertilizer > ex-root fetilization > smearing trunk. The daily average value of Ci shows ex-root fer-tilization of liquid manure > dropping fertilization > contrast with chemical fertilizer > smearing trunk > spray application,but the daily average value of Ls shows spray application of liquid manure > smearing trunk > contrast with chemical fer-tilizer > dropping fertilization > ex. -root fertilization. The daily average value of WUE shows smearing trunk of liquid ma-nure> spray application > contrast with chemical fertilizer > dropping fertilization > ex-root fertilization. The effect of spray application is the best.
