石灰性土壤含钙量较高,钙多为矿物态、代换态,有效态很少。偏碱性土壤钾、镁离子和硫酸根的数量增加,会抑制钙离子的吸收。受植株体从土壤中吸收钙素的特性影响和现在土壤养分中磷元素高水平都会造成钙缺乏。合理施用氮磷钾肥、平衡施用中微量元素、增加土壤有机物质和有益菌群,减少土壤中元素之间的拮抗,提高土壤的钙及其它营养元素供应能力。
Calcareous soil calcium content is high, mostly calcium mineral state, substitution, little effective. Alkaline soil potassium, magnesium and sulfate increased the number of calcium ions will inhibit the absorption. Affected by the characteristics of plants absorbing calcium from soil, and now the high levels of phosphorus in soil nutrients cause calcium deficiency. Rational application of N, P and K fertilizers, balance the application of trace elements, increase the soil organic matter and beneficial bacteria, reduce antagonism between elements in the soil, and improve the supply of soil calcium and other nutrients.
