| Abstract: | Based on experimental data, water saving and temperature raising effects of micro irrigation with plastic film mulch are analyzed and discussed. Comparing to border irrigation, water consumption may be reduced about 61%, soil temperature raised 3 ℃～6 ℃, and air relative humidity at near ground increased by 30%～40% under micro irrigation with plastic film mulch system. |

| Keywords: | micro irrigation with plastic film mulch water saving soil moisture and temperature raising |
