Abstract
In order to study the effect of film drip irrigation of different water sources on soil temperature,fertility indicator and yield of corn,by using the field contrast test method and regular observe on soil temperature,soil moisture and corn fertility indicators of the test area,the paper concluded that in the early period of corn growth,the soil temperature of surface drip irrigation treatment is higher than that of groundwater drip irrigation,and with the advance of growth period and the increase of soil layer,the ground temperature difference of two treatment decreases;the difference of two processing in moisture content is not obvious,comprehensive moisture content and temperature of two processing possess the inverse proportional relationship,but the surface water would weaken this relationship;the output of surface water drip irrigation treatment is 4.58% higher than that of groundwater drip irrigation treatment.It is visible that the surface drip irrigation under membrane has more advantages to crop growth and the increase of yield.
