摘要
施用氮肥是提高小麦籽粒产量、改善品质的重要措施,但是不合理施氮会导致氮肥利用率的降低,氮肥损失的增加。本文综述了小麦-土壤系统中氮肥对土壤氮素转化和小麦氮素吸收利用的影响及氮素损失等方面的研究进展。
Nitrogen fertilizer addition is very important for improving the kernel yield and quality of wheat but the unscientific use of nitrogen will reduce the nitrogen use efficiency and increase the nitrogen loss. The review aims to summarize the advanced research achievement on the effects of nitrogen addition on soil nitrogen transformation, nitrogen uptake by wheat, and nitrogen loss in the wheat- soil system.
