与常规农业相比，有机农业是实现农业可持续发展与食品安全的有效途径之一。而与常规农产品相比，有机农产品是否更加富有营养尚存在争议。对有关有机农产品与常规农产品营养价值的差异性研究进行了概述，结果表明尽管经过统计分析有机果蔬农产品矿物元素、维生素C（VC）与酚类次生代谢产物的含量显著高于常规农产品（P < 0.01），但不能简单判定有机农产品品质高于常规农产品。施肥方式，特别是有机肥氮素持久而缓慢的释放特征是有机果蔬营养品质较高的主要原因，但同时也是限制有机农产品产量的关键因素。如何在提高作物高产的同时，使农产品营养品质与口感最优化，将是今后研究的一个重要领域，需要开展广泛深入的研究。
Organic farming is recognized as an effective approach for agricultural sustainability and food safety. However, whether organic agricultural products contain more certain nutrients than conventional ones is still unclear. This paper summarized the differences in certain nutrients between organic and conventional agricultural products. Statistically, nutrients in organic products are significantly higher than that in conventional products, especially for vitamin C (VC), mineral compounds and secondary metabolites (P < 0.01). However, it is not reasonable to conclude that the quality of organic agricultural products is higher than conventional products only based on the content of a few nutrients. The possible mechanism of agricultural system and fertilizing pattern on products quality was discussed. The nutrient contents higher in organic products primarily results from the fertilizering pattern and the slow and long-term release pattern of plant nutrients, especially for N content in fertilizers. Therefore, further research should be conducted to improve nutritional quality and taste of crop products besides high yield.
