可溶性铝和锰有毒物质的存在和大量元素磷、钙、镁及微量元素钼的缺乏是是酸性土壤上花生生长不良和产量较低的主要原因。酸性土壤导致花生减产的主要原因是由于交换性AL对花生结荚有抑制作用。亩产165公斤花生荚果需从土壤中吸收15公斤钙。花生果发育所需要的Ca必须通过果实本身从土壤中得到,而不能从营养生长部分转移到地下 The existence of soluble aluminum and manganese toxic substances and the deficiency of a large number of elements phosphorus, calcium, magnesium and trace elements molybdenum are the main reasons for poor growth and low yield of peanut in acidic soil. Acidic soil lead to peanut production is the main reason for the exchange of AL peanut pod inhibition. 165 kg of peanut pod per acre need to absorb 15 kg of calcium from the soil. Ca required for the development of peanut fruit must be obtained from the soil through the fruit itself and not from the vegetative growth part to the ground
