不同施肥方式与施肥量对水稻产量及其氮肥利用效率的影响
Effects of fertilization methods and usage on yield and nitrogen use efficiency of rice
摘要
Abstract
[Objective]This study aimed to investigate the effects of different N application levels and nitro-gen use efficiency under artificial spreading and side-deep fertilization in paddy field.[Method]A field experi-ment was performed in Guohe town,Lujiang county,Hefei city,Anhui Province,in 2022,using Hui Liangyou 898 as the test supply variety.Four treatments were set up in the experiment,namely LN1(manual spreading+con-ventional nitrogen application),LN2(manual spreading+nitrogen reduction of 15%),MN1(side-deep fertiliza-tion+conventional nitrogen application)and MN2(side-deep fertilization+nitrogen reduction of 15%).[Result]The yields and the nitrogen use efficiency were increased by 8.04%-17.78%and 23.0%-29.4%,respectively.The differences between yields under side-depth fertilization were not significant,whereas the nitrogen use effi-ciency of the MN2 was significantly higher than MN1.[Conclusion]Side-deep fertilization significantly im-proved rice yield providing a scientific basis for the promotion of this technology.It is recommended to reduce nitrogen application by 15%to enhance nitrogen use efficiency in rice production.关键词
