| Abstract: |
| The laws of water consumption of corn and soybean were studied through the FAO Penman-Monteith method and the water balance method on the semiarid region of western Liaoning Province. Compared with that in corn monocropping and soybean monocroppiing, the actual evapotranspiration in intercropping system is 15.37 mm and 29 mm lower respectively in the whole growth period, while the quantity of water deficit is 45.54 mm and 5.68 mm less. The crop coefficient of intercropping system lies between corn monocropping and soybean monocropping, in addition, its degree of agreement between water demand and level of precipitation is better. |
