摘要:

为研究南安市国家级畜禽粪污资源化利用“整县推进项目”建设的可行性,以2018年各种作物产量和畜禽存栏量统计数据为基础素材,通过分析粪肥氮养分供给量和作物氮养分需求量,研究当年畜禽粪污土地承载力。结果表明,当年畜禽粪污土地承载力为659361个猪当量,比实际畜禽存栏量多153758个猪当量,全粪量肥料化当地利用是可行的。

Abstract:

In order to study the feasibility of constructing the national level "Whole County-wide Promotion Project" for the resource utilization of livestock and poultry manure in Nan'an, the land carrying capacity of livestock and poultry manure was studied by analyzing the supply of manure nitrogen nutrients and the demand for nitrogen nutrients of crops based on the statistics of various crop yields and livestock storage in 2018. The results showed that the land carrying capacity of livestock and poultry manure was 659361 pig equivalent, which was 153758 pig equivalent more than the actual stock of livestock. Therefore, using the whole manure fertilizer in local area is feasible.

Key words: livestock and poultry manure, integrated crop-livestock production, circular agriculture, green development, land carrying capacity
