摘　　要：研究了不同种植制度对农田土壤和蔬菜NO3--N含量的影响。结果表明,由于管理方式不同,土壤NO3--N含量依次为:大棚蔬菜地>露天蔬菜地>传统菜地;不同种类蔬菜硝酸盐含量绿叶菜类>豆类>瓜类>茄、果类>食用菌。叶菜类中硝酸盐含量均超过一级标准,污染指数高达3.50,污染最重;豆类,瓜类,茄、果类,食用菌样品中硝酸盐没有超过一级标准的,污染较轻。The effects of different cropping systems on content of nitric nitrogen in soils and vegetable were studied. The results indicated that, there is more nitric nitrogen in vegetable soils in green-houses, followed by opened vegetable soils, and then traditional vegetable soils; there is more nitric nitrogen in greenery vegetable in green-houses, followed by leguminous vegetable, and then melon vegetable, the lowest nitrates were found in nightshade vegetable. Nitric nitrogen in greenery vegetable exceed level I standard, pollution index is up to 3.50; Nitric nitrogen leguminous, melon and nightshade vegetable is below level I, which indicates these vegetable are light polluted.
