摘要
自2011年以来在我国东北、西北、华北三大甜菜主产区的不同土壤类型和栽培方式上。设置了110余个小区试验点次，进行了甜菜土壤营养诊断技术方法的研究与验证。为了在甜菜生产实践上能更科学、准确、快速、规范的进行甜菜土壤营养诊断，本文在此基础上从取样时间、取样方法、氮磷钾三种营养元素的常规测定和速测诊断方法进行了系统规范，并形成技术规程。
Since 2011, the technical diagnosis methods of sugar beet soil nutrition at over 110 field plot trials were conducted by different soil types and various cultivation patterns in North, Northeast and Northwest China. Under the foundation of this work, and also with the aim of diagnosing soil nutrition more scientific, accurate, normative and faster, the technical regulation for soil nutritional diagnosis of sugar beet was formed systematically and specifically in the aspects of soil sampling time phosphorus and potassium in conventional and rapid , sampling method, determination procedures of nitrogen, determining method.
