摘要
分析了已有中国农产品产地标准中存在的一些主要问题,认为制定全国统一的产地环境标准不仅技术难度较大,而且在实际应用过程中容易产生问题。在1∶25万尺度浙江省农业地质环境土壤地球化学调查的基础上,根据元素的地球化学组成、含量、分布状况、影响因子等因素,并考虑到对人体和生态环境产生影响的元素有效量,制定浙江省无污染农产品产地土壤环境质量标准(推荐)。虽然影响农产品质量的因素很多,如大气降尘、灌溉水、施肥等,农产品产地土壤环境质量终究是首要的。
Some main problems existent in the present standard for farm products areas of China are discussed in this paper. It is thought that the formulation of a nationwide environment standard for producing areas is not only technically difficult but also likely to give rise to lots of troubles in the course of practical application. Based on the 1：250,000 survey of earth geochemistry of the agro - geological environment in Zhejiang and the study of such affecting factors as the geochemical composition, content and distribution of el- ements and taking into account the effective quantities of elements that affect people and environment, the authors have formulated the standard of earth environment quality for the unpolluted farm products area in Zhejiang for recommendation. Although there are many factors that affect the quality of farm products, such as atmospheric fallen dusts, irrigative water and fertilizer application, the quality of earth environment in the farm products area obviously plays the most important role.
