资料报道:施用不同量的磷矿石(含少量磷酸)表明,增加用量会提高茶树成龄叶中钙的含量,增加钾的吸收和积累.采用适量磷酸,产量最高,而施氮量高则使土壤pH下降,增加土壤和叶片的锰含量.
The data reported that the application of different amounts of phosphate rock (including a small amount of phosphoric acid) showed that increasing the amount of calcium would increase the content of calcium and increase the absorption and accumulation of potassium in mature leaves of tea plants. The soil pH decreased, increasing soil and leaf manganese content.
