中文摘要:
      根据贵州省七星关区1∶5万耕地质量地球化学调查,获取了区内耕(园)地表层土壤、农作物与根系土等介质中多项元素或指标的高精度分析数据。开展了研究区耕地表层土壤养分丰缺及有害元素风险评价,以及部分农产品的安全性和富硒评价,结果显示,研究区耕地土壤养分综合质量以较丰富以上为主,土壤环境综合质量以安全利用类为主,耕地土壤综合质量整体较好,评价为中等及以上等级耕地19008万亩,占全区评价面积的9433%。全区富硒耕地资源丰富,达到优先保护、安全利用类土壤环境质量要求,且富硒的耕地16589万亩,占全区评价面积的8233%。在500亩以上坝区,达到优先保护、安全利用类土壤环境质量要求,并富硒的耕地152万亩,占坝区评价面积的9314%。已发现玉米、萝卜、白菜、马铃薯4类农产品富硒。
英文摘要:
      Guiyang 550018, Guizhou, China)According to the 1∶50000 cultivated land quality geochemical survey in Qixingguan area, Guizhou Province, the high-precision analysis data of many elements or indexes in the medium of cultivated (Garden) surface soil, crop and root soil were obtained. The results show that the comprehensive quality of soil nutrients in the study area is more than rich, the comprehensive quality of soil environment is mainly safety utilization, the overall quality of soil is better, and the evaluation is 1.908 million mu of cultivated land of medium and above grade Accounting for 94.33% of the assessed area. The area is rich in selenium rich cultivated land resources, meeting the requirements of priority protection and safe use of soil environment quality, and the selenium rich cultivated land is 1.658 9 million mu, accounting for 82.33% of the assessed area. In the flat ground area of more than 500 mu, the environmental quality requirements for priority protection and safe utilization of soil are met, and 15 200 mu of selenium rich arable land accounts for 93.14% of the assessed area of the flatland. Four kinds of agricultural products, corn, radish, cabbage and potato, have been found to be rich in selenium.
