李楠1,杨洋1,申逸男2,张秀双1,王紫1,郝鹏1 . 氮肥用量对优质粳稻产量、品质及氮肥利用率的影响[J]. 中国稻米, 2019 , 25(5) : 66 -68 . DOI: 10.3969/j.issn.1006-8082.2019.05.014
A field experiment was carried out to study the effects of nitrogen application rate on yield, nitrogen use efficiency and grain quality of rice by using Shennong 315 and Shendao 11 as materials. The results were as follows: when nitrogen application rate was 210 kg/hm2, the effective panicles, grain number per panicle and yield of the two varieties were both the highest, the yield were 9.82 t/hm2 and 9.15 t/hm2 respectively; when nitrogen application rate was 180 kg/hm2, the nitrogen use efficiency of the two varieties was 38.78% and 39.65% respectively, which was significantly higher than that of other treatments. The protein content, amylose content and taste value of rice were significantly affected by nitrogen application rate; the protein content, fatty acid content and taste value were significantly influenced by the interaction between variety and nitrogen application rate.
Key words： nitrogen application rate; nitrogen use efficiency; yield; grain quality
