通过对青阳黄石溪茶场黄壤和黄褐土钾含量以及茶树钾含量的分析研究,探讨土壤各形态钾与茶叶钾相关性。结果表明:黄壤土和黄褐土中的全钾含量主要与母质发育有关,而受生物及施肥的影响较小;速效钾和缓效钾的含量皆显现表层高下层低的规律,其中黄褐土中钾水平低于黄壤;黄壤和黄褐土的各形态钾含量与茶叶钾的相关性中,速效钾与茶叶钾含量的相关性最大。
Based on the analysis of potassium content in yellow soil and yellow cinnamon soil and potassium content in tea plantation in Yellowstone Creek green tea field in Qingyang, the correlation between various forms of soil potassium and tea potassium was discussed. The results showed that the content of total potassium in yellow loam soil and yellow cinnamon soil was mainly related to the development of parent material, but less affected by organisms and fertilization. The contents of available potassium and slow-acting potassium all showed the low surface layer, Potassium levels were lower in yellow soil than in yellow soil. Among the correlations between potassium content and potassium content in yellow soil and yellow cinnamon soil, the correlation between available potassium and potassium content in tea was the highest.
