【摘要】 本文在田间试验资料的基础上，综合考虑了影响冬小麦农田蒸散的气象、生物学特性和土壤水分等因素，选用蒸发力、冬小麦的叶面积指数和相对有效土壤湿度建立了新疆冬小麦农田蒸散估算模型，并且检验了该模型的计算效果。更多还原

【Abstract】 In the paper,based on the measured data in field,comprehensively considering over the meteorological condition,winter wheat biological property and soil moisture state,we established the calculation model for evapotranspiration of winter wheat field with evaporative power,winter wheat leaf index and relative effective soil moisture.The result of comparing the calculated evapotranspiration of winter wheat with the measured at the experimental plot in Xinjiang is that the model has good precision. \ \更多还原
