摘要
研究重度践踏下草坪草匍匐翦股颖新品系38号坪用性状的变化过程,包括自然高度、叶片长度、密度和地上植物量,结果表明,践踏末期,新品系38号自然高度低于对照品种28号(P<0.05),叶片长度差异不显著(P>0.05),密度高于对照品种28号(P<0.05)。灰色关联分析法综合评分结果表明,新品系38号的坪用性状好于对照品种28号。
The response of phenotypic traits of new train Yue Xuan No. 38 to heavy trampling was conducted. The results showed that turf height of Yue Xuan No. 38 was higher than that of control Yue Xuan No. 28, and there was no significant difference （P〉0.05） in tiller density and dry biomass between Yue Xuan No. 38 and Yue Xuan No. 28 at the last stage of heavy trampling. The weight of Yue Xuan No. 38 was heavier （P〈 0.05） than that of Yue Xuan No. 28 during the whole experimental period. Turf traits of the new strain Yue Xuan No. 38 was better than control Yue Xuan No. 28 based on grey correlation analysis.
