【摘要】 本文是在托克托县毡匠营村盐渍化土壤分布区,通过对主要盐生植物生长的根系土壤与对照土壤理化性状、含盐量及盐分组成比较研究。结果表明:该地几种盐生植物红砂、白刺和骆驼蓬生长的土壤环境性状与裸地对比研究中发现,土壤物理性状差异影响不明显。在土壤化学性状中,土壤总碱度差异明显;在可溶盐方面,几种盐生植物生长的土壤盐分类型是属于含氯化物为主的盐分类型。通过对几种盐生植物的体内含盐特点研究发现,红砂的生长环境要求土壤中含有氯化钠盐分类型为主。白刺生长的土壤环境中主要以氯化钠与硫酸钠为主的混合盐,骆驼蓬体内以氯化钠和碳酸氢钠成分为主。更多还原

【Abstract】 This article is in the county of TuoKeTuo ZhanJiangYing village salinification soil distribution area,through root system soil and comparison soil physics and chemistry character,salt content and salinity composition comparison research which grows to the several halophyte.Holds in the soil environment character and the bare land contrast research which the county five assorted hometown Zhanjiang camp village main halophyte Reaumuria songarica(Pall.) Maxim, Nitraria tangutorum Bobr and Peganum harmala L.grows discovered that,the soil physics character difference influence is not obvious.In the soil chemistry character,the soil total alkalinity difference is obvious;In the soluble salt aspect,the soil salinity type which several kind of halophytes grows is belongs contains the chloride primarily salinity type.Through to several kind of halophytes’ in vivo characteristic research discoveries,Reaumuria songarica(Pall.).Nitraria tangutorum Bobr.grows in the soil environment so long as by the sodium chloride and the sodium sulfate primarily compound salt.Peqanum harmala L.in vivo as are most take the sodium chloride and the sodiumbi carbonate ingredient.Artemisia capillaries.becomes wormwood in vivo by the sodium bicarbonate primarily.更多还原
