| Abstract: | A water saving and high efficiency irrigation procedure adopting a "ridge filmed and furrow irrigation"that is the "ridge which is covered with plastic film and furrow irrigation"technique is obtained for winter wheat under local climatic condition,based upon the experiment data of four experiment stations in 1998 and 1999,regarding the maximum output per m 3 water is regarded as the objective.In addition,it is compared with the border irrigation procedure under the same watering condition.The results show that by the "ridge filmed and furrow irrigation",the water of 29.7% can be saved,the yield of 633kg/hm 2 is increased,namely,the yield of 0.44kg and the output value of 0.53 RMB Yuan are raised for per m 3 water,and net income of 530 Yuan/hm 2 is improved,as compared with the border irrigation. |
