高尔夫果岭土壤配方与物理性质及匍匐剪股颖草坪性状相关关系的研究

用主成分分析对草坪性状指标进行了简化，用典型相关分析和逐步回归分析了高尔夫球场果岭土壤配方与土壤物理性质和匍匐剪股颖Agrostis stolonifera ‘Penncross’草坪性状的关系。结果表明：土壤配方成分对物理性质和草坪性状作用的大小依次为泥炭、中粗沙、极细沙和粉粘粒、细沙。泥炭和中粗沙主要作用于物理性质中的容重、总孔隙、毛管孔隙、饱和导水率以及选出的所有草坪性状指标。极细沙与粉粒粘粒和泥炭主要影响空气孔隙，细沙对所有物理性质和草坪性状的影响均不显著。建立了土壤配方指标与物理性质及草坪性状指标之间的量化方程。

Study on the physical properties of different turf-bed soil formula for golf green and the relationships with turf performance of creeping bentgrass

Creeping bentgrass performance indexes were simplified with principal component analysis and the relationships between the physical properties of different turf-bed soil formula and turf performance of creeping bentgrass were studied with canonical correlation and stepwise regression analysis.The results showed that the influence ability of components in turf-bed mixture on physical properties and turf performance were peat > middle-coarse sand > very fine sand plus silt and clay > fine sand.In the turf-bed...
