摘要:
以一年生青钱柳(Cyclocarya paliurus)苗为试验材料,对其进行5种不同土壤水分处理,研究不同水分条件下青钱柳苗高、地径、生物量及叶片含水量、叶绿素含量、丙二醛、可溶性糖含量等生长和生理指标。结果表明:苗高、地径的增长量及地上部分的生物量随土壤含水率的降低呈现递减趋势,而地下部分生物量和总生物量表现出先升高后降低的趋势,根冠比随土壤含水率的降低逐渐增大,土壤含水量为田间持水量的50% ~ 60%时总生物量为最大,随着土壤含水率的降低,叶片含水率逐渐降低,叶绿素含量总体呈现先升高后降低的趋势;土壤含水量为田间持水量的50% ~ 60%时的叶绿素含量最大,丙二醛和可溶性糖含量随着土壤含水率的降低逐渐升高;除土壤含水量为田间持水量的15% ~ 25%的处理组的植株长势较差,株高、地径和生物量的增长极缓慢外,其它4组在苗高和地径的净增长、地上和地下部分的生物量及总生物量方面的差异性不显著,叶片的可溶性糖含量在此水分范围内变化不显著,说明青钱柳在土壤含水量为田间持水量的25%以上均能适应生长,低于此值生长将受到限制。
Abstract:
Experiments were conducted on treatment of different soil water content on height and ground diameter growth, moisture content in leaf, biomass, chlorophyll, MDA and soluble sugar in 1-year Cyclocarya paliurs seedlings. The result demonstrated that with decrease of soil water content, height and ground diameter growth and above ground biomass decreased, underground biomass and total one increased first, decreased later, and root-shoot ratio increased. The total biomass of seedlings topped in soil with 50%-60% water content of field moisture capacity. With decrease of soil water content, moisture content in seedling leaf decreased, chlorophyll content increased first, decreased later, MDA and soluble sugar content increased. Chlorophyll content in seedlings leaf reached the highest in soil with 50%-60% water content of field moisture capacity. The experiments resulted that it had no evident difference of tested items among different treatments, except the one in soil with 15%-25% soil moisture of field moisture capacity, indicating seedling could grow well except the last one.
