摘要: 随着耕地质量保护与提升、化肥零增长行动项目在全国各地的普及推广,了解耕地养分状况就成为必不可少的工作。杭锦旗作为一个全国耕地质量保护与提升项目旗,2007-2009年共分析化验了5248块地块的养分含量,结果表明,全旗耕地的有机质、全氮、碱解氮含量属于低等水平;有效磷含量属于中等水平;缓效钾、速效钾含量属于较高水平;土壤偏碱性;除了有效硅属于极低水平外,有效硫、有效硼、有效锌、有效铜、有效铁、有效锰的均值都大于临界值,含量比较丰富。耕地质量总体上比1980年二次土壤普查的结果有所提高。

Abstract: With nationwide popularization and promoti on of projects of farmland soil quality conservation and elevation as well as zero growth action in fertilizer use, understanding farmland soil fertility status has been an essential work. Haggin banner is a project area of farmland soil quatily conservation and elevation. 5248 farmland soil samples were obtained in this area from 2007 to 2009 and nutrents data have been analyzed. The results showed that farmland soil organic matter, total N and alkalystic N in this area were at a relatively low level. Available P was at a middle level. While Available K and slowrelease K were at a relatively high level. In this area, farmland soil was alkaline. Except soil available Si, all soil available micronutrient content including S, B, Zn, Cu, Fe and Mn were higher than the critical value. Compared with the findings of second soil survey, farmland soil quality of Haggin banner has been improved.
