| Abstract: | The device of the neutron microzone was applied to inspect the evaporation capacity among plants in dryland corn farmland and results showed that the device was practical.In the west region of Shanxi,the evaporation capacity among plants is 55% above and over to the rain capacity(510 mm).The ratio of evaporation and evapotranspi- ration among plants was negatively correlated with leaf area index(LAI),and yield was positively correlated with crop transpiration. |

| Keywords: | the device of neutron microzone model evaporation among plants in farmland leaf area index crop transpiration |
