- 摘要:
- 对三江平原白浆土长达14年的长期定位试验得出:不施肥和施化肥处理,土壤锰、铜、锌全 量有下降趋势;除锰外,铁、铜、锌有效态含量有不同程度的增加;秸秆还田和有机肥处理,各元素含 量都相应增加。不同施肥处理,土壤 CARB-,OX-及 RES-Fe、Mn、Cu、Zn 含量均表现为减 少;施有机肥和秸秆还田,土壤中 EX-和 OM-Fe、Mn、Cu、Zn 略有增加,而 CK 与 NP 处理,两形 态含量都有减少。
- Abstract:
- The Dynamic Trend of Microelements Content and Forms in Albic Soil Under Long-term FerlitizationAbstract: This paper deals with the dynamic trend of microelements content and forms of Fe,Mn,Cu and Zn after 14 years long-term stationary under different fertilizing. The main results ob-tained from this experiment are as follows: under no fertilization and fertilizer, the total Mn,Cuand Zn in soil are decreased, but the available Fe,C,u and Zn are increased. The total and availablecontent of Fe,Mn,Cu and Zn are enlarged with application of manure and turning straw. Underdifferent fertilization, the forms of OX-,CARB-,RES- Fe,Mn,Cu and Zn are all declined.The content of EX- and OM-Fe,Mn,Cu and Zn under manure and turning straw are increased,but under no fertilization and only chemical fertilizer had the opposite effects.
