摘  要：
以柴达木盆地2种果型黑果枸杞所生长的土壤为试材,分别以pH计、电感耦合等离子体质谱仪(ICP-MS)、半微量凯氏定氮法、钼锑钪比色法、火焰光度计法、重铬酸钾—外加热法、质量法测定2种土壤中的pH、微量元素、大量元素、有机质以及全盐量的含量,分析二者间的差异。结果表明:2种不同果型黑果枸杞土壤中的pH表现为"圆球型"黑果枸杞土壤>"蟠桃型"黑果枸杞土壤,但不存在显著性差异(P>0.05);微量元素中Fe元素在2种果型黑果枸杞土壤的0~20、40~60cm土层存在显著性差异(P<0.05),表现为"圆球型"黑果枸杞土壤中的含量>"蟠桃型"黑果枸杞土壤中的含量;大量元素中全磷在20~40cm土层存在极显著差异(P<0.01),在0~20、40~60cm土层存在显著性差异(P<0.05),皆表现为"蟠桃型"黑果枸杞土壤中含量>"圆球型"黑果枸杞土壤中含量;全盐量在20~40cm土层存在极显著差异(P<0.01),在0~20、40~60cm土层存在显著性差异(P<0.05),皆呈现为"蟠桃型"黑果枸杞土壤中含量>"圆球型"黑果枸杞土壤中含量。

摘  要：
Taking two kinds of fruit type of Lycium ruthenicum Murr.soil in Qaidam basin as research materials,pH,the contents of trace elements,major elements,organic matter,total salinity of the soil were respectively determined by the equipments of pH meter and inductively coupled plasma mass spectrometry,and the method of semimicro-kjeldahl determination,Mo-Sb colorimetric method,flame photometry,dichromate method and mass method.The differences between two kinds of soil were analyzed.The results showed that‘Spherical type'of Lycium ruthenicum Murr.soil pH> ‘Peach type'of Lycium ruthenicum Murr.soil pH,but there was no significant difference(P>0.05).Among trace elements,Fe was the only one that had significant difference(P<0.05),which showed in 0-20 cm and 40-60 cm layers,and the content in ‘Spherical type'of Lycium ruthenicum Murr.soil>the content in‘Peach type'of Lycium ruthenicum Murr.soil;for total phosphor,there was a very significant difference(P<0.01)in the 20-40 cm soil layer,and significant differences in 0-20 cm and 40-60 cm soil layers(P<0.05),all showed that the content in‘Peach type'of Lycium ruthenicum Murr.soil>the content in ‘Spherical type'of Lycium ruthenicum Murr.soil;for total salinity,there was a very significant difference(P<0.01)in 20-40 cm soil layer,and significant differences(P<0.05)in 0-20 cm and40-60 cm soil layers,all showed that the content in‘Peach type'of Lycium ruthenicum Murr.soil>the content in‘Spherical type'of Lycium ruthenicum Murr.soil.
