| 摘 要： | 对重庆地区水稻土胶膜及基质土壤中某些元素含量情况及相互之间的关系进行了研究。结果表明:胶膜的pH值、有机质含量均明显高于基质土壤,且有机质含量差异极显著(P<0.01);胶膜中全氮、全磷含量高于其基质土壤且差异均达到极显著水平(P<0.01),全钾在胶膜与基质土壤中含量无明显变化,胶膜中铜、锌含量总体上高于其基质土壤,二者间锌含量差异达到显著水平(P<0.05);供试胶膜中全铁含量极显著高于基质土壤(P<0.01),全锰含量无一致性规律,胶膜中全锰含量总体上较基质土壤高,但二者差异不显著(P>0.05);供试胶膜中全磷与全铁含量显著相关(r=0.606*,n=12),具有较好的伴生关系,胶膜中铜与铁、锰含量均极显著相关(r铜铁=0.792**,r铜锰=0.737**;n=12),但铜与锰伴生关系较好,而锌与铁的伴生关系较好。

| Abstract: | The paper studied on the content of some elements and the correlation in cutans and matrix of paddy soils in Chongqing area. The results showed as follows: (1)The pH and the content of organic matter of tested cutans were both higher than the matrix soils. And the difference about the content of organic matter reached a greatly obvious level(P<0.01); (2)The content of total nitrogen and total phosphorus in cutans were significantly higher than the content of matrix soils(P<0.01). The content of total potassium in cutans and matrix soils was not obviously different. The total copper and total zinc content of soil cutans were also higher than the content of matrix soils, and the difference of total zinc content was remarkable (P<0.05); (3)The total iron content of cutans were significantly higher than the content of matrix soils (P<0.01). Generally speaking the contents of total manganese were higher than the content of matrix soils (P>0.05). (4) The content of total phosphorus was remarkable correlated with the content of total iron in tested cutans(r =0.61*,n=12).Thecoppercontentofcutanswasremarkablecorrelatedwiththeironandmanganesecontent(r铜铁=0.79**,r 铜锰 =0.74**;n=12). Generally speaking, the copper and manganese have the better symbiotic relationship, while the zinc and iron have the better symbiotic relationship. |
