摘要
[目的]研究河套农业经济区玉米产区生态地球化学特征.[方法]通过采集河套农业经济区玉米根系土及玉米各部位样品,分析了不同土壤类型根系土及玉米各部位的微量元素含量.[结果]灌淤土中大部分元素含量相对较高;大多数元素在玉米的茎叶中相对富集;F、Mn、Co元素在根中相对富集;N元素在子实中强烈富集,Zn、F在子实中相对较富集.[结论]建议河套地区玉米种植区在今后生产中应该合理施肥,控制化肥中有害元素的施入.
Abstract
[Objective] To research the eco-geochemical characteristics of corn production area in Inner Mongolia Hetao Agricultural Economic Zone.[Method] Corn root soil and corn samples from each part were collected from the Inner Mongolia Hetao Agricultural Economic Zone.Trace element contents in root soils and different parts of corn were analyzed.[Result] Most element contents in cumulated irrigated soils were relatively high.Most elements were relatively enriched in the stems and leaves of corn.F,Mn and Co were relatively enriched in roots of corn;N was strongly enriched in grain;Zn and F were relatively enriched in grain.[Conclusion] Corn production area in Hetao should rationaly apply fertilizer in production,and control the application of harmful element in fertilizer in future.
