| Abstract: | In Horqin sandland,the maize(Zea mays) leaf transpiration rate,sap flow,and soil evaporation were measured by using Li-6400 portable photosynthesis system,heat balance Dynamax packed sap flow measuring system,and micro-Lysismeters,respectively.The results of this study showed that during measuring period,the leaf transpiration rate ranged from 0.9 to 3.6 mm,the sap flow was about 7.3-29.8 g/h,the average soil evaporation occupied 20% of the total water utilization,but could increase up to 30% after irrigati... |
