| Abstract: | An evapotranspiration model suitable to Guangxi condition is chosen firstly.And by using phenological and experimental data,we determine crops coefficients of rice,maize and sugarcane every ten days of a month within their growth period,and calculate average water requirement,extreme maximum watre requirement and extreme minimum water requirement of the three crops.It can be taken as a basis of agriculture department defining optimum irrigation time and rational irrigation requirement. |

| Keywords: | evaportranspiration crops coefficient crops water requirement |
