Other Abstract



Data of a field experiment carried out at Zhangye Oasis, an arid region of northwest China, were used to evaluate the evapotranspiration during the growing seasons of a field of maize for seed. The evapotranspiration was obtained by two methods: Bowen-Ratio Energy Balance(BREB) and Reference Crop E- vapotranspiration-Crop Coefficient (ETo-K,) method. The analysis results show that in a whole growing period, the total ET is 513.2 mm and a daily mean 3.2 mm/d by BREB, while a total of 486.2 mm and a daily mean 3.1 mm/d by ETo-Kc. Using the results of BREB, some conclusions were drawn as follows. The ET varied with growing stages. In initial growing stage, developmental growing stage, middle growing stage and the late growing stage, the ET were 2.3,2.9,4. land 3.0 mm/d ,and with a percentage of total ET of 13%,22%,50% and 16%, respectively. In April and May, ET maintained in a lower level about 2.1-2.3 mm/d. ET increased sharply to 3.6 mm/d in June and got the maximal value of 4.6 mm/d in July. After that, it decreased lightly in August. With the coming of late growing stage, the ET decreased rapidly to 2.8 mm/d in September.
