| Abstract: | By less irrigation quota and less soil surface evaporation, trickle irrigation under film (TIUF) increase water use efficiency and decrease irrigation water requirement. A field experiment was carried out to study water requirement and its effect factors in cotton. It is found that TIUF not only lower irrigation water requirement, but also improve water utilization in entire cotton season. The leaf area index, yield and water use efficiency on field with TIUF increase obviously, comparing with furrow irrigation. |
