土壤pH值对盆栽大豆幼苗的影响

摘要

以大豆为试验材料,测定了盆栽大豆幼苗在酸或碱胁迫下的叶片相对电导率、可溶性蛋白含量、可溶性糖含量、含水量、株高等指标,结果表明:土壤pH为7.0 ～7.9时最适于大豆的生长发育.%This study tested the leaf relative conductivity, soluble protein content, soluble sugar content, water content and plant height of potted soybean seedlings under the stress of acid and alkali. The results showed that the soil pH ~ value of 7.0 ~ 7.9 was most suitable for the growth and development of soybean.
