| Abstract: | Combined with the method of dry crops test pit and field and by the three different irrigation modes,which is the sprinkler irrigation,furrow irrigation and no irrigation,the water requirement law of main dry crops in Poyang Lake basin is researched in order to find the sensitive period of water shortage and provide the theoretical basis for the critical water. At the same time, the crops water requirements coefficient was analyzed and the crops water utilization efficiency under the different irrigation modes was proposed. |
