摘　　要：为解决猕猴桃生产中使用鸡粪是否造成重金属污染等问题,以施用和未施用鸡粪堆肥的猕猴桃园土壤为研究对象,探讨施用鸡粪堆肥对猕猴桃园土壤氮(N)、磷(P)、钾(K)、钙(Ca)、镁(Mg)、锰(Mn)等矿质养分和铜(Cu)、锌(Zn)等重金属含量的影响,以期为鸡粪等畜禽粪便的科学再利用提供理论依据。结果表明,重金属Cu和Zn含量在施用鸡粪堆肥的猕猴桃园土壤中显著上升,但远低于重金属污染标准,并未造成土壤重金属污染。施用鸡粪堆肥显著影响猕猴桃园土壤养分含量,其中大量元素P、K含量显著提高,但N含量显著降低;中量元素Ca、Mg含量显著增加;微量元素Mn含量显著提高,但B元素含量差异不显著。鸡粪堆肥可以为土壤提供充足的养分,施用充分发酵后的鸡粪不会造成土壤重金属污染;施用鸡粪堆肥时应适当配施氮肥以保障养分均衡。In order to resolve the controversial questions of the heavy metal pollution that chicken manure composting was used in kiwifruit production,the contents of heavy metal such as copper(Cu)and zinc(Zn)and nutrients such as nitrogen(N),phosphorus(P),potassium(K),calcium(Ca),magnesium(Mg),manganese(Mn)on the soils of kiwi orchards with and without chicken manure composting were dis⁃cussed,in order to provide a theoretical basis for the scientific reuse of chicken manure.The heavy metal Cu and Zn content increased signifi⁃cantly after the application of chicken manure composting,but it was far below the heavy metal pollution standard and did not cause heavy met⁃al pollution in the soil.The chicken manure composting affect remarkably contents of soil nutrients,which the macro elements P and K contents were significantly increased by the application of chicken manure composting but the N content was significantly decreased,the medium ele⁃ments Ca and Mg contents were significantly increased,the micro elements Mn contents were significantly increased but B contents were no clear difference.Our results indicated that chicken manure composting can provide sufficient nutrients for the soil,while application of fully fer⁃mented chicken manure will not cause heavy metal pollution in soil,and nitrogen fertilizer should be properly applied at the same time to ensure nutrient balance.
