【摘要】 在三江平原白浆土上,采用长期定位试验方法研究了土壤中各形态Fe、Mn、Cu和Zn含量及其与有机质组分间的关系。结果表明,供试土壤全Fe、Mn含量略低于黑龙江省平均水平,而全Cu和Zn略高于黑龙江省平均水平,有效态Fe、Mn、Cu和Zn处于较高水平。各形态Fe、Mn、Cu和Zn的含量高低顺序为:RES-Fe>OX-Fe>OM-Fe>EX-Fe>CARB-Fe;OX-Mn>RES-Mn>OM-Mn>EX-Mn>CARB-Mn;RES-Cu>OM-Cu>CARB-Cu>OX-Cu>EX-Cu;RES-Zn>OX-Zn>OM-Zn>EX-Zn>CARB-Zn。白浆土中有效态铁、锰、铜和锌与易氧化碳、胡敏酸、富啡酸和松结态有机质之间呈显著或极显著正相关;除全铁外,全锰、铜、锌及有机态铁、锰、铜、锌和交换态铁、锰、铜、锌均与有机质总量、易氧化碳、胡敏酸和富啡酸等之间呈显著或极显著正相关。更多还原

【Abstract】 The various form contents of the iron, manganese, copper and zinc and the relationship between the organic matter and the various forms in the lessive was studied in this paper with the long-term position test method in the Sanjiang plain. It shows that the full content of the iron, manganese in the test soil is slightly lower than the average level and the full content of the copper, zinc is slightly higher than the average level of the soil in Heilongjiang Province. It also shows that the effective forms of the iron, manganese, copper and zinc are on a high level. The forms content order of the iron, manganese, copper and zinc is RES-Fe>OX-Fe>OM-Fe>EX-Fe>CARB-Fe, OX-Mn>RES-Mn>OM-Mn>EX-Mn>CARB-Mn, RES-Cu>OM-Cu>CARB-Cu>OX-Cu>EX-Cu, RES-Zn>OX-Zn>OM-Zn>EX-Zn>CARB-Zn. It is the significant or highly significant positive correlation between the effective forms of the iron, manganese, copper and zinc and the readily oxidizable carbon, humic acid, fulvic acid, pine Junction organic matter in the lessive. In addition to the full form iron, it is the significant or highly significant positive correlation between the full forms of the manganese, copper, zinc, the organic forms of the iron, manganese, copper, zinc, the exchangeable forms of the iron, manganese, copper, zinc and the total organic matter, the readily oxidizable carbon, humic acid, fulvic acid and so on.更多还原
