| Abstract: | Compared with main grain crops,the leaf area indices and the rates of sunlight energy utilization of alfalfa(Medicago sativa L) in different growing periods in Tianshui of Gansu Province were calculated and analyzed by field experi-ments. The superiority for utilization of alfalfa on the sunlight energy to the main grain crops was quantitatively described. |
| Keywords: | Alfalfa(Medicago sativa L) Grain crop Leaf area index Rate of sunlight energy utilization |
