本文通过对酸性土壤小麦镁营养与铝及钙、钾之间关系研究,明确了土壤酸度(主要是活性铝)是小麦缺镁的诱导因素。施用镁肥可以矫治缺镁症,而施用石灰(中和土壤酸度)效果更好,不仅安全消除缺镁症,且改善小麦整体营养而大幅度增产。据此可以认为,酸性土壤小麦缺镁是铝毒的一种表现形态,文章还对钙、钾对镁的关系作了一些探讨
In this paper, we studied the relationship between magnesium nutrition and the contents of aluminum, calcium and potassium in acid soils, and clarified that the soil acidity (mainly active aluminum) is the inducing factor of wheat magnesium deficiency. Application of magnesium fertilizer can cure magnesium deficiency disease, and the application of lime (acid soil neutralization) better, not only to safely eliminate magnesium deficiency disease, and improve overall wheat nutrition and substantial increase in yield. Based on this, it can be concluded that magnesium deficient in acidic soils is a manifestation of aluminum toxicity. The article also discusses the relationship between calcium and potassium in magnesium
