通过调节土壤酸碱度,研究不同土壤pH值对多叶羽扇豆的生长发育及生理特性的影响。结果表明：多叶羽扇豆植株随着土壤pH值的降低,叶片黄花率降低,叶绿素含量升高;POD活性升高,叶片内SOD活性的影响呈升高降低的趋势,2年生植株较1年生植株影响更为明显。土壤pH对多叶羽扇豆叶绿素a/b比值及CAT活性的差异性不显著。

Infection of different pH of soil on growth and physiological characters of Lupinus polyphylla was studied.Results indicated that with the decline of pH,the rate of yellow plant decreased while chlorophyll rose in content,the activities of peroxidase(POD) increased and SOD activities increased also.The chlorophyll content a/b and activity of catalase were no significant difference with soil pH change.
