- Abstract:
- The device of the neutron microzone model was applied to inspect the evaporation capacity among plants in dryland corn farm land.The results showed that the device was practical.In the west ernregion of Shanxi province the evaporation capacit yamong plants accounts for more than 54% of the annual precipitation rain capacity(510mm).The ratio of evaporation to transpiration among plants was negatively correlated with leaf area index,and yield was positively correlated w ith crop transpiration.
