摘要： 水稻完成某一生育期所需的有效积温常因环境而异，表明广泛应用的线性积温法需要修正。分析表明，日最低温度比日最高温度效应更显著，说明发育速率与温度间呈非线性关系。于是，本文提出了一个具有较好预测性的非线性温度效应模型。它较其他非线模型的优点在于其参数的生物学意义清晰。对积温的不稳定性，它解释为：有效积温

Abstract: The widely-used temperature sum approach, which assumes a linear relation between crop development rate (R) and temperature (T), needs to tbe improved, because the temperature sum required to fulfil a given phonological phase in rice varies considerably even among environments without photoperiod ef
