| 摘 要： | Based on full consideration of the winter wheat biological characters,an agrometeorologicalmodel of physiological thermal index of winter wheat including vernalization and photoperiodresponse is established,in which the influence of diurnal variation of temperature,effectivetemperature and daylength on the development of winter wheat during the period from emergenceto elongation are comprehensively considered.Validation of the model using the data taken fromthe experiments of wheat ecology in China shows that the model behaves well with mean error lessthan 3 days.
