| 摘 要： | 根据不同方式计算鸡粪施用量,进行连续6茬蔬菜施用鸡粪田间试验,研究农田土壤中磷的累积特征。结果表明:土壤中全磷、树脂态磷、碳酸氢钠提取态磷、氢氧化钠提取态磷和稀盐酸提取态磷含量均随着鸡粪用量的提高而显著提高,且含量增幅随着种植茬数的增加而提高,故在生产实践中以作物需磷量配施鸡粪较优,否则由此所引起的土壤盈余磷素流失或淋失对地表水和地下水水质的潜在影响风险较大。

| Abstract: | Six successive vegetable field trials were conducted to investigate the phosphorus accumulation in soils fertilized with chicken manure(CM).The application rates of CM were determined by the P-based and N-based requirement of vegetables respectively.The results showed that total P,Resin-P,NaHCO3-P,NaOH-P,diluted HCl-P in soils increased with the increase of chicken manure application rates,and with the increase of crop cultivation times.Therefore,the application rate of chicken manure should not be too high... |
