钙的元素符号是Ｃａ。按目前的分类方法 ,它是中量元素。钙是植物结构组分元素。1 植物对钙的吸收和转运植物以二价钙离子的形式吸收钙。虽然钙在土壤中含量可能很大 ,有时比钾大 1 0倍 ,但钙的吸收量却远远小于钾 ,因为只有幼嫩根尖能吸收钙。大多数植物所需的大量钙通过质流
The element symbol of calcium is Ca. According to the current classification method, it is the amount of elements. Calcium is a plant structural component element. Absorption and transport of calcium by plants The plant absorbs calcium in the form of divalent calcium ions. Although calcium levels in soils can be quite large, sometimes 10 times greater than potassium, the amount of calcium absorbed is much less than that of potassium because only young root tips absorb calcium. Most plants require large amounts of calcium to pass through the mass flow
