摘要
在贵阳地区特定的地貌及气候条件下,秋播特高、杰威、蓝天堂3个多花黑麦草品种,生育期均达250天左右,属中晚熟品种;3个品种的分蘖均呈"S"型增加,特高、蓝天堂的分蘖能力明显强于杰威;3个品种均以1.5 g/m2和2.0 g/m2密度下的分蘖能力最强;品种×密度互作效应对分蘖具有明显的影响;适度茬次刈割对多花黑麦草的分蘖也具有明显的促进作用。
Under a particular landscape and climate conditions of Guizhou,The reproductive period of three Italian ryegrasses is Up to 250 days or more Which is autumn sowing, so they are in late - maturing varieties;their Tillers were ＂S＂ increasing complefly, Tetragold and Blueheaven were stronger than Splendor;But tillering ability is most at 1.5g/m^2 and 2.0g/m^2 ; moreover, Species × density interaction effect and Stubble times have obvious influence and promote the role on tiller. It provides a theoretical basis and technical guidance about Scientifically plant and use of Italian ryegrass,as web as it is conducive to better promote and use of Italian ryegrass in Gui zhou province.
