| 摘 要： | 在选取的4种土壤上 ,用甲鱼温室排放的富含营养物的养殖废水和商品营养液作对比进行了生菜栽培试验。试验表明,不同的土壤对甲鱼废水显示出不同的适应性 ,土壤对甲鱼废水中的铵氮和磷的去除率较高 ,4种土壤中以红壤为最 ,分别达95.3 %和96.8 %。甲鱼废水既能够提高土壤中有效态K、Ca的含量 ,促进植物的生长 ,还能减少因甲鱼废水的任意排放而造成的环境污染。

| Abstract: | The paper studied on an integrated production system that included the rich nutrient wastewater drained from industrial Chinese-turtle pond and vegetable irrigated with this in plastic greenhouse. Lettuce cultivating experiments were engaged in selected four soils controlled with commercial nutrient solution. Various soils had different adaptability to turtle pond wastewater, alluvial soil was better than that of others. Soils had a high eliminating rate for ammonium nitrogen and phosphorous. Red soil was higher than that of others and the removal rate was 95.3% and 96.8% respectively. It has been shown Chinese-turtle pond wastewater can improve pH of red soil and increase the available calcium and potassium and it can promote vegetable growth and decrease the environmental pollution caused by drainage of Chinese-turtle pond wastewater arbitrarily. |
