| Abstract: |
| The middle-lower reach of the Tarim river and the peacock river is one of the most dry and water shortage regions in our country.Above 95% of the water resource in this area is used in irrigation for the agriculture.Irrigation method is the inundation flooding Irrigation.The water waste is seriously.The shortage of water resources limits the economy.We conducted experiments using drip irrigation underside film for cotton in 2002.The results show as following: The appropriate drip irrigation amount underside film for cotton production in this area is 3 931.5 m3/hm2.The optimal lint cotton yield is 2 997.75 kg/hm2.Compared with the traditional irrigation way,this irrigation method can save 8 070～1 470 m3/hm2 water,increase 747.75 kg/hm2 lint cotton.It is testified that the drip irrigation underside film is one of the most saving irrigation ways for cotton production in this area currently. |
