【摘要】 研究了不同阴香群落中幼苗营养元素的含量及其与土壤养分之间的关系。结果表明:阴香幼苗营养元素含量幅度分别为:N 15.3-4.1 g/kg;P 0.4-0.2 g/kg;K 4.9-2.3 g/kg;Ca 16.1-1.9 g/kg。阴香幼苗元素含量差异显著,各器官中以叶的营养元素含量最高。各元素中以Ca的变异程度最大,变异系数为61.12%,K的变异程度最低,变异系数为25.95%。阴香幼苗各元素之间相关性显著,但与土壤养分之间相关性不显著,这主要是由阴香的生物生态学特性所决定的。更多还原

【Abstract】 This paper mainly dealt with the nutrition content in different organs of Cinnamomum burmanni seedlings and its relationship with the soil fertility.Its found that nutrition content of Cinnamomum burmanni seedlings,such as N,P,K,Ca respectively rangd from : 15.3～4.1,0.4～0.2,4.9～2.3,16.1～1.9.So we consider that the nutrition content varies with different organs,the leaf has the biggest nutrition content,The variation coefficients of Ca is among the biggest(61.12%),and that of K is among the least(25.95%)(25.95%).Correlation analysis indicated that : the nutrient elements in various organs of Cinnamomum burmanni seedlings were interrelated one another mostly at the level of 0.01,but it’s not significant correlation with soil fertility,that maybe caused by the ecological characteristics of Cinnamomum burmanni seedlings.更多还原
