太行山区绿色 有机苹果生产模式对果园环境质量的影响

采用绿色、有机生产模式,旨为生产品质安全、有良好经济效益的果品,同时优化生态环境,提高环境质量。以太行山区连续9 a采用绿色、有机生产模式的苹果园为研究对象,对其2003年和2012年的园地土壤、灌溉用水和大气环境质量进行了检测对比。结果表明：2003年和2012年该果园的园地土壤、灌溉用水和大气环境质量均符合国家绿色、有机食品生产标准。与2003年相比,2012年大气中的NOx和氟化物浓度显著增加,总悬浮物浓度显著降低;灌溉用水中总铅、总镉、总砷含量显著提高,总汞和六价铬含量显著降低,灌溉用水质量与集雨场风化岩石的重金属含量直接相关,受生产模式影响较小;土壤中重金属汞、镉、铅、铬和铜含量显著降低,与生产模式密切相关。

The Effect of Green and Organic Apple Production Models on Environmental Quality in Taihang Mountain Area

The production m6dels of green and organic could produce the fruit with safety and good economic benefits, while optimize the ecological and improve environmental quality. Taking apple orchard with green and organic production models 9 years continuously in Taihang soil, water and air in 2003 and 2012 were tested and and air in the orchard in 2003 and 2012 were accord mountain area as the research object, the qualities of analyzed. The results showed that the qualities of soil, water with national green and organic food production standards. Compared with 2003, the concentrations of NOx and fluoride in the air in 2012 were increased significandy, the concentration of total suspended solids was decreased significantly. The contents of total lead, total cadmium, total arsenic in the irrigation water in 2012 were increased significantly, the contents of total mercury and chromium （VI） were significantly reduced, the irrigation water quality directly related to the heavy metals content of weathered rock in rainfall field, and there was little effect with the production model. The contents of heavy metals mercury, cadmium, lead, chromium and copper in the soil in 2012 were reduced remarkably, and closely related with the production moldel.
