Poultry Wastewater Land-Spreading Management Based on Eco-Agricultural Park: A Case Analysis of Huaning, Sichuan

The paper investigated the effects of irrigation of poultry waste water on soil fertility and biomass production of cabbage in accordance with the standard of Environmental Technical Terms for Green Food Production Area (NY/T391-2000). The results showed that irrigation of 46.88m3 per hectare every 10 days resulted in the highest production of biomass of cabbage as well best soil fertility index. When a farm garden with considerable scale is available, abatement of poultry wastewater from intensive breeding farm by internal industrial chain extension of eco-agricultural park (EAP) is a simple, feasible, economic and effective mode. At present, the internal farm garden of Huaning EAP reserves a capability of 30,000m3·a-1 in absorbing the wastewater from the breeding farm.
