摘　　要：以KWS0143、PRESTIBEL、包育302和农大甜研4号4个甜菜品种为材料,比较不同甜菜品种钠素吸收性能的差异。结果表明:(1)不同甜菜品种植株中钠素含量最高达4.2%,其中叶丛最高为5.8%,块根中最高为1.2%;品种间最明显的差异是国外品种块根中钠素含量高于国内品种。(2)植株中钠素累积量农大甜研4号与KWS0143皆高于包育302和PRESTIBEL,叶丛中累积总量高于块根;不同品种钠素累积量分配在叶丛和块根中的差异较明显,KWS0143和PRESTIBEL分配到块根的大于叶丛,而农大甜研4号和包育302与之相反。(3)两个国外品种的最高钠素吸收速率均高于国内品种。(4)KWS0143产量较高,PRESTIBEL产量低,农大甜研4号产量与KWS0143接近,包育302产量低于KWS0143;农大甜研4号和包育302的含糖率和纯度皆高于KWS0143和PRESTIBEL。Comparative analysis was carried out on differences of Na absorbency in four sugarbeet varieties. The result showed： （1）the highest of Na contents in different varieties of sugarbeet was up to 4.2 percent, 5.8 percent in phyllome, 1.2 percent in root. Na contents of foreign sugarbeets were obviously higher than that of native ones. （2）Na accumulative content of the NongDaTianYan4 and KWS0143 were higher than that of the BaoYu302 and PRESTIBEL, the accumulative content in phyllome was higher than that in tap root. There was a significant difference between phyllome and root for the distribution of Na in different varieties; In KWS0143 and PRESTIBEL, the Na distribution in root was higher than that in phyllome, but that of NongDaTianYan4 and BaoYu 302 were contrary. （3）The Na highest absorption rate of foreign sugarbeets higher than that of native ones. （4） The yield of KWS0143 was higher and PRESTIBEL was lower. The sugar content and purity in BaoYu302 and NongDaTianYan4 were higher than that in KWS0143 and PRESTIBEL.
