蔬菜受污染主要来自两个方面:(1)生产基地生态环境受污染,如土壤、大气与水质遭受“三废”或重金属等污染;(2)蔬菜生产过程中化学农药、化肥的大量施用、残留与转化。另外许多蔬菜作物对某些污染因子有富集作用,增加了污染性。优质无公害蔬菜生产应采取以下主要农艺措施: 建立稳定的高标准无公害蔬菜生产基地。
The pollution of vegetables comes mainly from two aspects: (1) the ecological environment of the production base is polluted, such as soil, air and water quality suffer from “three wastes” or heavy metal pollution; (2) large quantities of chemical pesticides and fertilizers in vegetable production process, With conversion. In addition many vegetable crops have some of the pollution factors enrichment, increased pollution. High-quality pollution-free vegetable production should take the following major agronomic measures: Establish a stable high-standard pollution-free vegetable production base.
