| 英文摘要 | Vegetables provide an important source of selenium (Se) for many regions of China. Excess nitrogen (N) fertilizers are commonly used for vegetable production. In this regard, the effect of inorganic N-fertilizer application on the Se content in soils and plants was evaluated in vegetables produced in a polytunnel greenhouse vegetable system. Vegetables were continuously cultivated for 6 years in a microplot field experiment and treated annually with conventional N fertilizer (870 kg ha(-1) inorganic fertilizer) and 0 kg N ha(-1) as control treatment in polytunnel greenhouse vegetable system in the Taihu Lake region of China. Both treatments included 234 kg ha(-1) N provided by manure. After each harvest, soil and vegetable samples were collected, and analyzed for soil NO3-N, Olsen-P, Se, phosphate extractable S and Se and vegetable Se. Six years of continuous application of inorganic N-fertilizer resulted in a significant accumulation of NO3-N, Olsen-P and extractable S in the soil over the course of the experiment. Soil NO3-N concentration accumulated up to 600 mg kg(-1) with application of inorganic N-fertilizer, while soil phosphate extractable Se and vegetables Se concentration were significantly lower than that those grown in control treatments. The negative effect of continuous application of inorganic N-fertilizer on vegetable Se concentration may be a consequent of excessive accumulated soil NO3-N. When NO3-N concentration was greater than 300 mg kg(-1), vegetable Se concentration was negatively correlated with soil NO3-N. The negative effect of continuous application of inorganic N-fertilizer on vegetable Se concentrations was likely the result of soil nitrate's competitive or antagonistic effect on Se uptake by vegetables grown in an intensive polytunnel vegetable cultivation system. |
