【摘要】 为了使多叶羽扇豆能在西安露地开花,用硫磺粉调节土壤pH值,研究了不同土壤pH值对1、2年生多叶羽扇豆生长发育的影响。结果表明:1、2年生植株叶片都表现出随着pH值的升高,植株叶片变黄越早,黄化率升高和1年生植株叶片叶绿素含量降低的趋势;pH7.4的处理1、2年生植株比其他处理花期长,pH7.6的处理1、2年生植株比其他处理花数多;pH 7.4的处理1年生植株结实率、种子重、种子千粒重,2年生植株结实率比其他处理高。更多还原

【Abstract】 Infection of different pH of soil on growth and developing of Lupinus polyphylla was studied by different pH of soil with sulfur powder in order that Lupinus polyphylla can bloom on the soil of Xi an.Results indicate:there is a trend that the pH is higher,the rate of yellow plant is more and the first day of yellow leave is earlier both annual and biennial plants as well as the content of chlorophyll is less in annual plants;the day of flower and No.of bloom is more in pH 7.4 and 7.6 than others; the No.of seed,the rate of seed,the weight of thousand seeds in annual and the rate of seed in biennial in pH 7.4 plant is higher than others.更多还原
