    摘要:

    本文通过盆栽生物试验和室内培养试验,对大麦和小麦两种作物不同生长发育阶段的耐盐性进行了研究.结果表明,两种作物均在萌芽期、苗期和拔节孕穗期对土壤盐分最敏感.随土壤盐度增加,作物对钠的摄取量剧增,对钾的摄取量明显减少,对钙的摄取量在苗期和拔节孕穗期也有一定程度减少.此外,随土壤盐度增加,作物叶中Ca/Na比和K/Na比均降低,其中尤以K/Na比的降低最显着,表明盐分胁迫下作物吸钠对钾吸收的影响最大.本文还就盐分敏感期作物易受盐分胁迫的可能机制进行了探讨.

    Abstract:

    Excessive salt in salt-affected soil affects the growth and development of crops.Although soil salinity affects the growth and development of crops at all the growth stages,the salt-sensitiveness of some crops differ remarkably at various stages.To lerance to salinity is not a fixed property of a species but varies with the growth stages of the crop.A pot culture experiment was conducted to determine salt tolerance of barley and wheat at various growth stages.The soils tested were salinized at various stages with distilled water containing salt at four levels.After salinized,the osmotic potential of soil solution increased by 0,-0.4,-0.8 and -1.6MPa,respectively.
