摘要
Abstract
Waste water from turtle pond is by-product from turtle production, which is a kind of nutrient resource for plant. The concentration of NH+4-N was 20～30 mg/L-1 and those of other mineral nutrients were lower. To improve the quality of waste water for vegetable in hydroponic production system, four treatments were used in vegetable hydroponic experiment, waste water, waste water with nitric acid added, waste water with nitric acid and iron added, mixture solution of waste water and commercial nutrient solution.In tomato hydroponic producing system, turtle breeding wastewater was used as nutrient resources. Four separated hydroponic systems were built in the greenhouse at Zhejiang University. The results showed that waste water could not use as nutrient solution directly in vegetable production. During the experiment, tomato grew well with improved waste water. N, P and other mineral nutrients in tomato were measured. The change of water quality was monitored during the experiment. It could provide an effective way to reuse turtle breeding waste water.关键词
