摘要
秋冬季节在贵阳通过塑料大棚内外不同温度和光照水平生产紫羊茅（ＦｅｓｔｕｃａｒｕｂｒａＬ．Ｐｅｎｎｌａｗｎ）地毯式草坪的协相关分析得出：光照强度（ｘ）与分蘖数（ｙ）有直线回归关系，棚内分蘖数极显著高于棚外（Ｐ＜００１），温度对分蘖数影响最大。
The carpet-lawns of Festuca rubra L. Pennlawn were placed in plastic house and natural conditions in autumn and winter.The joint relationships between tillering quantity and illumination intensity and temperature were studied.The results showed that it had a linear relationship between tillering quantity and illumination intensity.The tillering quantity in plastic house was remarkable higher than that of in natural conditions.In addition,the temperature had the greatest influence on tillering quantity.
