摘　　要：以超高产大豆辽豆14与普通大豆辽豆11为试材,研究了不同施肥水平和种植密度处理下,钙和镁在各器官的积累与分布。结果表明:大豆各器官钙百分含量依次为叶片>叶柄>荚皮>籽粒>茎秆;镁百分含量依次为叶柄>叶片>荚皮>茎秆>籽粒。随着生育时期的推移,大豆茎秆和籽粒中钙百分含量逐渐降低,叶片和叶柄中钙的百分含量始粒期以前呈下降趋势,始粒期以后呈增加趋势,荚皮中钙百分含量随着生育时期推移波动较小。大豆茎秆、叶片和叶柄中镁百分含量均在始花期最高,荚皮中镁百分含量在盛荚期最高,籽粒中镁百分含量在始粒期最高。和辽豆11相比,各肥密处理中辽豆14各器官钙和镁的百分含量均高于辽豆11。钙积累总量肥力处理间差异显著,密度处理间差异极显著。镁积累总量密度处理间差异极显著。钙和镁积累总量肥力、密度和品种间具有显著的交互作用。Ca and Mg were the essential microelements of soybean,which play an important role in its growth and yield formation. The objective of this article was to study the accumulation and distribution of Ca and Mg in super-high-yielding soybean. Comparative analysis of nutrition accumulation and distribution were carried out through 2 years experiments with super- high-yielding soybean variety of Liaodou 14 and common soybean variety Liaodou 11 under different fertilizer levels and planting densities. Results showed that the order of Ca content in the organs of soybean was leaf 〉 petiole 〉 pod 〉 grain 〉 stem ; Mg content was petiole 〉 leaf 〉 pod 〉 stem 〉 grain. As the plant growth, the Ca content of stem and grain reduced gradually,and those of leaf and petiole showed a decrease trend before initial grain filling stage and then changed to an increase trend, the Ca content of pod was invariable during the whole growth stage. The Mg content of stem,leaf and petiole at initial flowering stage were higher than those at other growth stages, Mg content in pod and grain were higher at full podding and initial grain filling stage, respectively. Compared with those of Liaodou 11, the Ca and Mg content in different organs of Liaodou 14 were higher. Difference of total Ca accumulation reached a significant level under different fertilizer and density treatments ;There was a significant difference of total Mg accumulation under different density treatments. Different fertilizer, density treatments and cultivars showed a significant interaction.
