摘要/Abstract

摘要：

为了解施肥对蔬菜地土壤、蔬菜和地表水体中δ¹⁵N丰度的影响,选择2012至2018内施用不同肥料的28块蔬菜地（包括13块施用化肥蔬菜地、8块施用畜禽粪蔬菜地和7块施用商品有机肥加化肥蔬菜地）,采样分析表层土壤、蔬菜地上部分和地下部分及地表径流样的δ¹⁵N丰度。结果表明：施肥种类对土壤、蔬菜和地表径流中δ¹⁵N丰度均可产生显著影响,其丰度值由高至低依次为：畜禽肥>商品有机肥加化肥>化肥。蔬菜和地表水与土壤之间的δ¹⁵N丰度存在正相关。分析认为,蔬菜产品中氮同位素组成可以作为鉴定有机蔬菜的辅助依据,地表水体中δ¹⁵N丰度可作为水体中氮素污染源的指标。

关键词: 蔬菜地, δ¹⁵N丰度, 有机蔬菜, 有机肥, 化肥, 污染源识别

Abstract:

To understand the effect of fertilization on the abundance of δ¹⁵N in soil, vegetables and surface water, 28 plots of vegetable field applied with different fertilizers during 2012 to 2018, including 13 plots with chemical fertilizer, 8 plots with livestock manure and 7 plots with commercial organic fertilizer and chemical fertilizer, were selected. The surface soil, both aboveground and groundwater parts of vegetables, and surface runoff samples in the fields were collected and their abundance of δ¹⁵N was measured. The results showed that fertilizer types had significant effects on the abundance of δ¹⁵N in soil, vegetables and surface runoff, and the abundance decreased in the order of livestock and poultry fertilizer > commercial organic fertilizer + chemical fertilizer > chemical fertilizer. There was a positive correlation between the abundance of δ¹⁵N in vegetables and surface water and soil. It is concluded that the nitrogen isotope composition of vegetable products could be used as an auxiliary basis for the identification of organic vegetables, and the abundance of δ¹⁵N in surface water could be used as an indicator of nitrogen pollution sources in water body.

Key words: Vegetable Field, δ¹⁵N Abundance, Organic Vegetables, Organic Fertilizer, Chemical Fertilizer, Pollution Source Identification
