摘 要：
以广玉兰幼苗为试材,采用生态学方法,研究了喀斯特地区6种不同岩性的土壤与广玉兰幼苗养分含量间的变化和影响,以期为喀斯特地区广玉兰幼苗的培育、生长和施肥提供参考依据。结果表明:在不同岩性的土壤上,土壤养分及广玉兰幼苗体内营养元素含量之间均存在显著差异;在不同岩性的土壤上,广玉兰幼苗对土壤有效养分的吸收在石英砂岩上最好,在第四纪红色粘土上最差;广玉兰幼苗在其整个生长过程中,对氮素和磷素的吸收较多,对钾素的吸收则相对较少。

摘 要：
Magnolia grandifloraseedlings were used as test materials,the ecology method was used to study the changes and effect between soil nutrient and the Magnolia grandiflora seedlings nutritive elements content on the six kinds of different lithology,it aimed to provide reference and basis for the Magnolia grandifloraseedlings cultivation,fertilization and its growth.The results showed that on the different lithology,the soil nutrient and the nutritive elements content of Magnolia grandifloraseedlings was different significantly from each other;on the six kinds of different lithology,the Magnolia grandiflora seedlings was the best to the soil available nutrient′s absorption on the silicarenite,but was the worst on the Quaternary Period red clay;through the entire growth process of Magnolia grandifloraseedlings,the absorption of nitrogen and the phosphorus element was more,and the absorption of potassium was relatively less.
