小麦前氮后移的施肥效应与有效使用条件

The Effect of Nitrogen Application under Different Conditions at Late Growth Stage of Wheat

研究了高产小麦前氮后移的增产作用,指出这一技术与品种类型、土壤肥力、播种密度等条件有密切关系,在生产中运用前氮后移施肥技术必须与看苗管理、应变措施结合起来。

The effect of N application at late growth stage on yield increase of highyield- ing wheat was studied. The experiment was shown that N application at late growth stage was closely related to variety types, sowing density and soil fertility. The using N application at late in wheat production must combine with manage according seedling growth and environment.
