在田间试验基础上 ,采用常规气象与土壤湿度资料 ,运用数理统计方法建立了南疆棉田实际蒸散量的计算模式。结果表明 :土壤湿度系数Kw与相对有效土壤含水率Aw具有直线相关性 ;计算值与实测值相比较 ,计算效果较好。
On the basis of field experiments, using conventional meteorological data and soil moisture data, the mathematical model was established to calculate the actual evapotranspiration of cotton field in southern Xinjiang. The results show that there is a linear correlation between the soil moisture coefficient Kw and the relative effective soil water content Aw. Comparing the calculated value with the measured value, the calculated result is better.
