| 摘 要： | 为了研究膜孔灌玉米农田尿素转化和分布特性，在测坑中进行了膜孔灌和畦灌施尿素试验，分析测定了施尿素后不同时间的土壤铵态氮和硝态氮含量。研究表明：膜孔灌尿素转化完全后，土壤中氮素的主要形态为硝态氮，可作为膜孔灌农田氮素水平评价的指标；基施尿素下，土壤中的硝态氮含量逐渐增大，分布范围以施肥点为中心呈大致成半圆形；灌水方式对尿...

| Abstract: | In order to study the characteristic of urea transformation and distribution in corn field with film hole irrigation,the content of ammonium nitrogen and nitric nitrogen of different time is determined.The result shows that when the urea has transformed under film hole irrigation,the form of nitrogen is mainly nitric nitrogen,which can be used as the assessment indicators of field under film hole irrigation.With urea basal dressed,the content of nitric nitrogen increases gradually and the distribution range... |
