Evaluation of Soil Nitrate Nitrogen and Ammonium Nitrogen in Rice Fields of Qiandongnan Prefecture
摘要
Abstract
[Objective] To study soil nitrate nitrogen and ammonium nitrogen content in rice fields of Qiandongnan Prefecture.[Method] Nitrate nitrogen,ammonium nitrogen content of 146 soil samples collected from Qiandongnan Prefecture were measured,and the content of nitrate nitrogen,ammonium nitrogen,and the classification and distribution of available nitrogen were analyzed and compared among counties.[Result] The soil nitrate nitrogen,ammonium nitrogen content had obvious difference between the counties,the average concentration of nitrate nitrogen from Zhenyuan County was the highest,while that from Cengong County was the lowest;the average concentration of ammonium nitrogen from Sansui County was the highest,while that from Majiang County was the lowest.Available nitrogen distributed from 3 to 6 grades,mostly in the 5 and 6 grades in Qiandongnan Prefecture.[Conclusion] More than 90％ rice field soil is deficient in soil available nitrogen.关键词
