枇杷的不同器官中元素地球化学特征

枇杷是药用价值很高的一种经济水果。研究不同母岩类型产区的枇杷中元素的地球化学特征,发现同一品种枇杷中元素的富集部位各不相同;而不同品种的枇杷所富集的元素种类大致相同,只是富集程度有差异。有益、营养元素在叶片中的含量大多高于其他部位;有害元素不超标。与枇杷果关系较为密切的营养元素主要为N、P、K、Ca、Mg;微量营养元素为B、Zn、Cu。

GEOCHEMICAL CHARACTERISTICS OF ELEMENTS IN DIFFERENT ORGANS OF LOQUAT

Loquat is a kind of economic fruit with very high medicinal value. Researches on geochemical characteristics of elements in loquat from several areas with different mother rock types show that the elements are concentrated in different organs of loquat, and that different species of loquat are enriched in approximately the same sorts of elements, with somewhat different degrees of enrichment. Beneficial and nutritional elements are more concentrated in leaves than in other organs. Harmful elements do not exceed the standard. N, P, K, Ca, Mg, B, Zn and Cu make up the main nutritional elements for loquat fruit.
