吉尔吉斯斯坦土壤的微量元素评价

Evaluation of Trace Elements in the Soil of Kyrgyzstan

【目的】初步探明吉尔吉斯斯坦6个州农区和草场的土壤微量元素的"丰缺"情况,并针对"丰缺"情况提出建议。【方法】对吉尔吉斯斯坦楚河州、塔拉斯州、奥什州、贾拉拉巴德州、纳伦州、伊塞克湖州等6个州52个样点,156份土壤样品中的铜、锰、锌、铁、硼5种微量元素有效性含量进行数据统计、分级评价。【结果】吉尔吉斯斯坦锰、锌元素含量极其丰富;铁、硼元素总体含量也比较丰富;而铜元素有58.14%的样品分布在低或极低水平,铜元素含量比较缺乏。【结论】根据吉尔吉斯斯坦的情况,适当施用铜肥和硼肥是改善土壤缺素状况、改良土壤肥力的有效途径,锰肥和锌肥短期内不需施用。

[ Objective ] A preliminary study of ＂the abundance and deficiency＂ phenomenon in the grass- land soil trace elements of Kyrgyzstan＇s 6 states was carried out and relevant suggestions to deal with it were made. [ Method ] Statistical data and classification evaluation of the contents of 5 kinds trace elements： cop- per, manganese, zinc, iron and boron of 156 soil samples in 52 sites of the 6 states, Chu oblast Talas, Osh State, Dezhou State, Naryn Jalalabad, Isaac of Huzhou in Kyrgyzstan were carried out, [ Result ] Kyrgyzstan was extremely rich in manganese and zinc and quite rlch in iron and boron elements; And the copper content was deficient or very low in about the 58.14% sample collected. [ Conclusion] According to the situation in Kyrgyzstan, the appropriate application of copper and boron fertilizer was an effective approach to improve soil nutrient deficiency condition, Manganese and zinc were not needed in the short term.
