| Abstract: | According to the meteorological data between the year 1999 to 2003 of Guanzhong Region in Shaanxi province,the reference crop evapotranspiration of summer maize during various growing periods is calculated out by adopting the formula of Penman-Monteith.With the comparison to the data obtained through large-scale weighing lysimeter,the variation of the crop coefficient of different growing periods is analyzed.The result implies that the average reference crop evapetranspiration during crop growing stage in G... |
