尿素转化与控制在夏玉米上的应用

Urea Transformation and Control on Summer Corn's Application

尿素在土壤中的水解速率主要受土壤脲酶活性的影响。当前控制尿素水解转化的有效技术措施有添加脲酶抑制剂、硝化抑制剂、尿素包膜以及表面膜技术的应用等。笔者从尿素包膜技术应用及在夏玉米上的施用等方面探讨提高尿素氮利用率的途径。

The hydrolysis rate of urea in soil is controlled by many factors such as urease activity,the current control of the effective conversion of urea hydrolysis technical measures have added urease inhibitor,nitrification inhibitors,as well as surface film coated urea technology applications.The author coated urea technology applications from the summer corn and the increased application of urea,and other aspects of nitrogen use efficiency.
