农牧交错带土壤营养元素分布及其改善途径——以内蒙古自治区多伦县为例

Distribution of available soil nutrients in Duolun County located in the interlaced area of agriculture and pasture and reclaimation measure

    摘要
  • 摘要: 对农牧交错带内蒙古自治区多伦县61个表层土样测定分析表明，有32．0％ 的土样有机质含量 < lg／kg，40％ 的土样有机质含量为1～3g／kg，属中等水平，仅有28％ 的土样有机质含量为3g／kg。大量元素中32．7％ 的土壤缺N，58．9％ 缺P，19．5％ 的土壤缺K；微量元素中100．0％ 的土壤缺Mo，88．7％ 的土壤缺Zn，52．7％ 的土壤缺B，24．3％ 的土壤缺Mn等。并进行综合评价，指出不同地型各类土壤合理施肥、退耕增产及其沙化治理、改善生态环境的对策。

     

    Abstract: Sixty-one topsoil samples around Duolun County were collected and analyzed．The results show that soil organic matter content averages 3．10g／kg(0．89～13．68g／kg)，alkaline hydrolytic nitrogen 26．6mg／kg(50．1～ 1325．0mg／kg)，Olsen-P 4．89mg／kg (1．0～ 15．0mg／kg)，available potassium 126．0mg／kg，available zinc 0．68mg／kg (0．18～ 4．18mg／kg)，available manganese 12．9mg／kg(2．44～34．57 mg／kg)，water soluble boron 0．49mg／kg(0．12～0．94mg／kg)，and available molybdenum 0．05mg／kg(0．027～0．091mg／kg)．Evaluations according to the above results indicate that 32．7％ of the soil samples are deficient in available N ，58．9％ in P ，19．5％ in K ，88．7％ in Zn，52．7％ in boron，24．3％in Mn．Distribution map of the available soil nutrients are drawn and reclamation measures are recommended also ．
