摘要: 采用盆栽试验研究氮肥用量对水稻新品种“绿旱一号”生长及产量的影响。结果表明:氮肥用量对“绿旱一号”叶面积指数、分蘖数、叶绿素含量、产量因素及产量均有较大的影响,在2.3g/盆(纯氮、折合260kg/hm2)的氮用量范围内,产量随氮肥用量的增加而增加,超过2.3g/盆尿素的氮肥用量,则产量下降

Abstract: Effect of nitrogen applied fertilizer on growth and yield of rice Lv Han No 1 was studied in pot experiment .The result showed that leaf area index and tiller and content of leaf chlorophyll and yield of Lv Han No 1 influenced for nitrogen applied fertilizer. Under 2.3 gram nitrogen per pot(260kg/hm2) , rice yield increased with the raise of nitrogen applied fertilizer and rice yield decreased when nitrogen applied exceed 2.3 per pot.
