| 中文摘要: |
| 基于Meta分析，研究畜禽粪肥类型、耕作方式和施肥量对土壤中Cu、Zn、Cd和As含量的影响。结果表明：畜禽粪肥（鸡粪、猪粪和牛粪）施用会显著提高耕地土壤中Cu、Zn、Cd和As含量，其平均含量的增幅分别可达18.14%、16.44%、16.61%和14.81%；与施用鸡粪和牛粪相比，施用猪粪土壤Cu含量增加显著，且其Zn和As含量的增幅也最高；高粪肥施用量（≥60t/hm2）下土壤Cu、Zn和Cd含量的增幅均达35%以上，而低粪肥施用量（≤30t/hm2）下其含量的增幅均低于20%；旱地和水旱轮作2种耕作方式下施用粪肥土壤中金属元素含量显著增加，而水田耕作方式下其含量无显著变化。 |

| The effects of livestock manure types， tillage and fertilizer application amount on the content of Cu，Zn，Cd and As in soil were studied by Meta analysis. The results showed that the application of livestock manure(chicken manure，pig manure and cow dung) significantly increased the content of Cu，Zn，Cd and As in cultivated soil， with an average increase of 18.14%，16.44%，16.61% and 14.81%，respectively. Compared with the application of chicken manure and cow dung， the application of pig manure significantly increased the content of Cu in the soil，and the content of Zn and As also increased the most. The content of Cu，Zn and Cd in soil with high manure application rate(≥60t/hm2)increased by more than 35% while that with low manure application rate(≤30t/hm2)increased by less than 20%. The content of metal elements in the soil applied with manure increased significantly under dry farming and water-dry rotation cultivation， but did not change significantly under paddy cultivation. |
