| Abstract: |
| Based on the experiment data of summer maize in Irrigation Experimental Station of Northwest A&F University during 20012004,a normalized model between leaf area index(LAI) and accumulated temperature was developed.By using the data of LAI in 3 years,the equation is greatly authentic.It may provide an accurate technique for monitoring the growth of crops and estimating the yields in loess areas. |
