摘要
岩石的结构和成分在一定程度上决定着土壤的结构和成分,茶园土壤结构和对应岩石结构存在依存关系,茶叶、土壤和岩石中无机元素含量间也有一定关系,通过这些关系的对比分析发现:优质信阳毛尖主产区的成土母质结构较粗、硅铝钾含量高而钙钠含量低;优质茶园土壤要求成土母质粒状矿物多、硅铝钾高而钙钠低,符合这些特点的所有岩石都适合作为茶园成土母质,但S型和A型花岗岩更为优越,开辟新的茶园应该循此规则。
The texture and composition of soil partly controlled by the rock beneath it. By analysis of tex-ture relationship between soil and corresponding rock, through statistics of inorganic elements in tea, soil and soil parent material in the product area of Xingyang Maojian Tea, the author find that The coarse grain tex-ture, high content of Si, A1, K and low content of Na and Ca are considered as the major reason for which the high grade Xingyang Maojian tea mainly produced in granite area. Meanwhile, qualified soil of tea garden require the soil parent material which characterized by high content of granular mineral, SiO2, Al203 and K20, but low content of Na20 and CaO. So, S - type and A - type granite are more suitable for soil of teagarden.
