冻融作用对猪粪模拟施肥条件下东北黑土中重金属铜锌活性的影响
随着规模化养殖场的发展和饲料添加剂中Cu和Zn的添加,畜禽粪便中重金属Cu和Zn含量较高,通过畜禽粪便施肥可能造成土壤重金属污染。畜禽粪便施肥和冻融作用均可能影响土壤中重金属的活性,进而改变土壤重金属的环境效应。本文针对东北气候特点,通过实验室模拟,研究了猪粪施肥和冻融作用对黑土中重金属Cu和Zn活性（可交换态和碳酸盐结合态）的影响。结果表明：同未施肥的对照比,猪粪施肥初期,Cu和Zn的可交换态含量均明显增加,而Cu和Zn的碳酸盐结合态含量则略有下降;同低施肥量比,高施肥量下,Cu和Zn的可交换态含量略有增加,而Cu和Zn的碳酸盐结合态含量下降;同施肥初期比（1周）,随施肥时间延长（1个月）土...

| Notes | 12-1437/S With the development of large-scale farms and the addition of Cu and Zn in feed additives, high Cu and Zn contents in feces of livestock and poultry occurred, and may cause soil pollution of the heavy metal especially Cu and Zn by livestock and poultry manure fertilization. Both fertilization of livestock and poultry manure and freeze-thaw action can alter the activity of heavy metals in soil, and furthermore change the environmental effect of heavy metals in soil. This paper aimed at the influence of freezing and thawing on the activities of Cu and Zn （ exchangeable and carbonate） in black soil of Northeast China under pig manure fertihzation according to the northeast climate character- istics through laboratory simulation. The results showed that the contents of exchangeable Cu and Zn significantly increased and that of car- bonate Cu and Zn slightly decreased under pig manure fertilization initial stage comparing with the control without fertilizer. The contents of exchangeable Cu and Zn slightly |
