摘要：通过2年来对金叶榆容器苗生长的观测以及基质分析,了解不同基质的营养成分和理化性质对苗木生长的影响。试验结果表明,不同基质对苗木的树高和地径生长存在极显著差异,但每年各基质对苗木生长作用的排序有一定的变化。以农林废弃物为主要成分的轻型基质的理化性质会发生一定程度的变化,大多数基质的营养成分(全氮、全磷和全钾)基本是同比下降,与此有关的EC值和ECE值也呈同比下降趋势,基质的pH和密度则同比上升。经过主成分分析,基质中全氮、pH、CEC值、全磷和密度是影响金叶榆容器苗生长的主要因素。
The observation of seedling growth and media analysis during the past two years were made to understand the effect of the nutrition content of different media,physical and chemical properties on the height and diameter of Ulmus pumila container seedlings.The results show that the difference of the seedlings＇ growth in the different media was extremely remarkable,and that the role of different light media on the growth of Ulmus pumila container seedlings changed in the ranking every year.The physical and chemical nature of media,mainly formed with agricultural and forestry wastes occurred to some extent.The nutritional content（total N,total P,total K） were lower in 2009 than in 2008,so were the EC value and the ECE value,but the pH value and density were higher.By means of principal component analysis,it is found that total N,the pH value,the CEC value,total P and density played a main role in the growth of Ulmus pumila seedlings container.
