摘要
为研究干旱胁迫环境对草地早熟禾叶片生长发育的影响,在定量的时空坐标系内建立相应的生长模型,从而预测干旱胁迫条件下草地早熟禾叶片外观形态及生理变化;通过对温室中试验植株进行干旱胁迫后得到的生长数据的观测研究,统计归纳出草地早熟禾叶片外观参数随着干旱胁迫时间增加而变化的模型。结果表明:该模型符合草地早熟禾叶片在干旱胁迫环境下的生长规律,模型能够很好的描述在干旱胁迫作用下草地早熟禾叶片的生长发育过程。
The model of determining the correlations between apparent parameters and drought stress days was established by surveying the growth data from tested Kenblue,aPoa pretensis variety,under different drought stress days to study the effect of drought stress on leaf growth and development of Poa pretensis in the quantitative space-time coordinate system.Results：The established model with meeting the natural law of leaf and environment interaction effectively reflects the leaf growth status under the water shortage condition,which can provide a certain reference for the interactive simulation between plant growth and environment change.
