摘要
监测了澄城苹果产区大气、土壤质量并进行评价。监测结果表明:4项大气质量指标、6项土壤质量指标均未超过国家《无公害食品苹果产地环境条件》限制,产地环境条件完全能够满足食品安全(无公害)的生产要求。评价结果示明了可悬浮颗粒物、As分别为大气、土壤的关键控制因子,提倡果园种草,增加植被覆盖,降低大气可悬浮物,减少苹果果面污染,禁止果园使用福美砷等砷制剂,以避免土壤砷的积累。
Environmental quality of atmosphere and soil in apple production base of Chengcheng County is evaluated in this paper. The monitoring results show that 4 atmosphere quality indexes and 6 soil quality indexes are all in the range of “no-harmful apple producing environmental condition”, so this area can be determined as a no-harmful apple production base. It is demonstrated that the suspending granules in atmosphere and arsenic in soil are the major controlling polluters. In order to decrease the pollution of fruit surface, it is necessary to plant grass in orchards with the purpose to increase vegetation coverage and to decrease suspending granules in atmosphere, and to forbid the application of asomate and other arsenic pesticides to avoid the arsenic accumulation in soil.
