摘要
以2个大豆(Glycine maxMerrill.)品种华春18、浙春3号为材料,设置不同浓度的铝处理进行土培,研究铝对大豆主要生长特性的影响.结果表明:适量的铝处理对大豆生长具有一定的促进作用;高浓度铝会对大豆产生不利影响,阻碍大豆株高、茎粗、叶面积、比叶重的增长.2个品种比较,浙春3号抗铝胁迫的能力大于华春18.
The study dealt with the effect of different supplementation Al on some growth characteristics of two soybean (Glycine max Merrill) varieties ("Zhechun No. 3", "Huachun No. 18"). The result showed that condign concentration of AI can promote the growth of soybean, high aluminum concentration may impede the growth of soybean result in decreasing of the plant height, soybean caudex diameter, leaf area, lamina mass per unit area etc. The tolerance capability to AI of Zhechun No. 3 was showed to be stronger than that of Huachun No. 18.
