从世界范围来看,对于无公害蔬菜的基本概念,先后出现过许多相似的提法,诸如清洁蔬菜、健康蔬菜、无农药污染蔬菜、天然食品等等,至今尚未对无公害蔬菜的概念形成统一的说法。笔者认为:以国家颁布的《食品卫生标准》为衡量尺度,农药、重金属、硝酸盐、有害生物(包括有害微生物、寄生虫卵等)等多种对人体有毒物质的残留量均在限定的范围或阀值以内的蔬菜产品,可统称为无公害蔬菜。本文主要阐述无公害蔬菜培植的技术要素以及生产现状。

This paper mainly describes the technical elements of pollution-free vegetable cultivation and production status quo.
