摘要
通过相关性研究和校验试验表明,内蒙西部平原地区冲积土有效氮的测定,采用1.8N NaoH水解氮的方法是较好的。通过校验试验确定了土壤的肥力指标。根据土壤碱解氮测定值即可获得胡麻氮肥的建议施肥量。
A correlative research and field's calibrabive experiments confirms that, the best method for extraction of avaiable nitrogen from soil in alluvial soil of the plain area of, the west Inner Mengolia, is 1.8N NaOH hydrolytic nitrgen. From the field experiments the calibration for soil fertility can be obtained. According to the calibration of hydrolytic nitrogen, the recommendation of N-fertilizer is obtained
