贵阳市无公害中药材基地农业环境质量监测与评价

Monitoring and evaluation on agricultural environmental quality at the production bases for pollution-free traditional Chinese medicinal materials in Guiyang City

基地环境质量是影响无公害中药材生产的关键因子。对贵阳市修文县小箐乡中药材种植基地大气、土壤和农用灌溉水的监测结果显示,该基地大气各污染指数均达清洁水平;14个土壤监测点的单项污染指数均小于1,综合污染指数在0.36～0.74之间,有11个点综合污染指数小于0.7,属清洁水平,其余3个点属尚清洁水平;农用灌溉水质单项污染指数均小于0.5,综合评价指数在0.06～0.28之间,属于清洁水平。说明小箐乡中药材种植基地的土壤、灌溉水、大气环境质量良好,符合《绿色食品产地环境技术条件》NY/T391-2000规定的基地环境质量标准,可以满足无公害中药材的生产要求。

The environment quality of production base is one of the key factors for producing pollution-free Chinese medicinal materials.The present study was conducted to monitor the atmospheric,edaphic and irrigation water quality in production bases of Chinese medicinal materials in Xiaoqing Town,Xiuwen County,Guiyang.The results showed no atmospheric pollution at the bases.The individual pollution index of 14 soil monitoring sites was all less than 1,the comprehensive pollution index was between 0.36-0.74,and 11 sites of them scored less than 0.7,which were at clean level,while the other 3 sites were just clean.The individual pollution index of agricultural irrigation was less than 0.5,and the comprehensive pollution index was between 0.06-0.28,which was at clean level.As a whole,the soil and agricultural irri-gation,and atmospheric environment quality in plant production bases of Chinese medicinal materials in Xiaoqing Town found in healthy conditions,which were in accordance to the environmental quality standard rules,NY / T391-2000（Environmental Quality Condition of Green Food Producing Area）,and completely in accordance with the production requirement of pollution-free traditional Chinese medicinal materials.
