| 摘 要： | 该文基于种养平衡的生态模式，根据上海地区单位饲养规模畜禽场粪便产生量及其氮磷含量和各类农作物氮磷需求量，研究分析了基于氮磷养分管理的单位养殖规模畜禽场产生的粪便还田利用需匹配的三大类农作物种植面积。结果表明：在畜禽粪便作为农作物氮磷养分的来源和满足农作物氮养分需求的前提下，根据农作物对氮磷养分需求的木桶效应，各类畜禽粪便提供的磷养分总体上超过各类农作物对磷养分的需求量，具有流失污染环境的隐患。因此，提出了畜禽场粪便还田利用农田面积匹配应基于农作物磷养分需求，不足的氮养分可通过化肥氮给予补充，从而达到种养结合、环境友好的畜禽生态养殖。

| Abstract: | Based on the TN and P2O5 contents of animal manure and the TN and P2O5 demands of different groups of crops in Shanghai suburbs, the suitable areas for cropland application of animal manure was analyzed and evaluated. The results show that, the areas for cropland application of animal manure based on the P2O5 demands of crops is more than that based on TN demands of crops, and is adopted as the suitable areas for cropland application of animal manure according to the cask theory of nutrient absorption of crops, which could reduce the potential loss of phosphorus and environment pollution. |

| Keywords: | animal manure cropland application suitable area environmental safety Shanghai suburbs |
