Mehlich3法在新疆棉花土壤养分分析中的应用
Applications of Analysis in Xinjiang Cotton Soil to Nutrient by Mehlich 3 Method
摘要
Abstract
[ Objective ] The aim of this study was to evaluate The feasibility of Mehlich 3 method which was used to test soil available P, K, Cu, Zn, Mn in Xinjiang Uygur Autonomous Region. [ Method ] This thesis focuses on the Mehlich 3 and other current methods used in measuring the nutrients in the cotton soil of Xinjiang. [Result]The results showed that a close correlation was found between the values determined by the Mehlich 3 and the method for P, K, Cu, Zn and Mn, and the correlation coefficient was 0.936, 0.903 2, 0.844 6, 0.785 6 and 0.977 6 respectively. In addition, the element contents determined by the Mehlich3 were three times as that determined by the referred methods on Mn, but there was little difference on Zn. Measued by ICP accurately. [ Conclusion ] It has been find that M3 is high in preciseness, so the result is reliable.关键词
