| 摘 要： | 采用分期播种的方法，研究了秋播紫羊茅的株高生长动态和分蘖动态，并建模拟模型。研究结果表明，温暖的气候有利于紫羊茅株高生长，而凉爽的气候可促进其分蘖。但炎热与低温气候均不利于紫羊茅幼苗生长。秋播紫羊茅在生育期１５ ～３５ 天时株高生长较快，３５ 天之后，株高生长速率减慢，分蘖速率加快。秋播紫羊茅的株高生长动态可用 ｙ ＝ ａ ＋ ｂ／ ｘ 模型模拟，分蘖动态可用逻辑斯谛模型模拟。

| Abstract: | The dynamics on growth in plant height and tillering of Festuca rubra in autumn planting were studied and established its simulation models. The result showed the temperate weather was beneficial to growing in plant height of fole Festuca rubra , and cool weather could promoted Festuca rubra tillering. However, both burning hot and cold weather were not advantageous to growth of Festuca rubra seedling. The dynamics on growth in plant height of Festuca rubra in autumn planting could be simulated by y=a b/x model, that of its tillering could be simulated by Logistic model. |
