| Abstract: |
| 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. |
