摘　　要：通过正弦指数模型描述黄瓜在各个生长阶段发育速率与温度的关系.以连栋温室2006—2007年3茬黄瓜生育期资料为基础,得到不同生育阶段模型所需参数.利用2008年试验资料对模型进行了验证,并进一步与有效积温法对各个试验的模拟结果进行比较.结果表明,模型能够较好的预测各个生育期的出现时间和持续天数,且预测效果要优于有效积温法.The simulation of cucumber growth stages is necessary for studying its growth in relation to environment. To explain the relationship of temperature and growth rate of each stage, the exponential sine equation has been derived. The parameters of the model in different stages were confirmed by 3 groups of data about cucumber growth stages from 2006 to 2007, while the data in 2008 was used to check the model. Finally, the model was compared with the results of the growing degree days. The result shows that the starting time and days of each development period are simulated well by exponential sine equation. Compared with the growing degree days, the forecast precision of exponential sine equation precedes.
