摘要
通过对福建莆田解放钟枇杷园中土壤和各器官组织中的N、P、B、K、Ca、Mg等6种元素含量的测定,应用生物地球化学分室理论分析,发现解放钟枇杷对所需的营养元素一般为主动吸收,如N、P、B、K、Ca、Mg等元素在地上活体分室中分配的总量均占整个解放钟生态系统的总储量的80.0%以上,其中最大的为B元素,活体分室分配总量占生态系统总储量的97.64%,最小的为N元素,为83.97%。各营养元素在活体分室总的分配次序为:B>K>Ca>Mg>P>N。
N, P, B, K, Ca and Mg altogether six elements in the soil, various organs and tissues of Putain ＂Jiefangzhong＂ loquat garden in Fujian province were measured in this paper,The result indicated that Putian ＂Jiefangzhong＂ loquat was forwardly absorptive to nutritive elements such as N, P, B, K, Ca and Mg through compartment theoretical analysis of biogeochemistry. The live shoot ac- counted up to 80.0% in the ecosystem, the highest was B （97.64%）, and the lowest was N （83.97%）. Nutritive elements of live shoot in descending order was B 〉 K 〉 Ca 〉 Mg 〉 P 〉 N.
