摘要
在福建省长泰岩溪镇,研究3种养猪污水灌溉方式(浇灌法、开沟法、自排法)对森林土壤理化性质的影响。结果表明:养猪污水通过浇灌法和开沟法引入林地后,土壤通气持水性提高,土壤物理性质得到有效改良,但自排法使土壤通气持水性变差; 3种方法污灌后,土壤全氮基本持平,全钾、碱解氮、速效钾分别提高25. 62%、37. 52%、327%,而有机质含量总体呈降低的趋势,p H、全磷和速效磷受污灌方式影响较大。理化性质关联性分析表明:养猪场污水改善森林土壤物理性质、提高土壤养分状况排序为:开沟法>浇灌法>自排法,人工开浅沟引流的方式对土壤改良效果较好。
This paper studied the effects of livestock breeding wastewater on forest soil physicochemical properties by three ways（ spray,ditching and natural emissions）,in Yanxi Town,Changtai County of Fujian Province. The results showed that soil permeability and physical properties improved after sewage watering by spray and ditching. The soil permeability deteriorated after natural emissions. After sewage watering in all three methods,total nitrogen and total phosphorus constant in the soil,but total potassium,alkaline nitrogen and available potassium in the soil increased by 25. 62%,37. 52% and 327%. Organic matter declined in all soil after sewage. p H,total phosphorus and effective phosphorus were greatly influenced by different methods. Analysis of the correlation of soil physical and chemical properties indicated that the order of effect of improving soil physical and chemical properties was ditching spray natural emissions. Sewage watering by ditching is the best method to improve forest soil physicochemical properties.
