| 摘要: |
| 在选择出适宜广西蒸散模式的基础上,利用广西物候资料及实验资料,确定了水稻、玉米、甘蔗生长期内逐旬作物系数,并计算了几种作物的平均需水量、极端最大需水量、极端最小需水量,为农业部门确定最佳灌溉期和合理的灌溉量提供依据。 |

| 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. |
