Abstract

Salt-tolerant cucumber(Cucumis sativus L.)cultivar‘Jinchun No.5’and salt-sensitive cucumber cultivar‘Jinyou No.1’were used as materials.Taking NaCl(525 mg?kg-1)as salt-stress condition,the tanks are used to culture 2 different cucumber cultivars in the greenhouse.We compared the effect of growth and soil enzyme activities of these 2 different cucumbers in the root zone.The results show that the yield per plant and dry weight of salt-sensitive cucumber cultivar‘Jinyou No.1’is significantly lower than that of salt-tolerant cucumber cultivar‘Jinchun No.5’.And the leaf area of‘Jinyou No.1’after transplanting 50 d and soil dehydrogenase activity after transplanting 40 d are significantly lower than‘Jinchun No.5’.Under soil salinization condition,the inhibited urease,catalase and dehydrogenase activity of salt-tolerant varieties‘Jinchun No.5’are lighter than that of salt-sensitive varieties‘Jinyou No.1’in rhizospher after transplanting 30 d,40 d.
