以小麦新品种扬辐麦4号为试验材料,设置了4个氮肥用量和4个种植密度,分析其对扬辐麦4号产量结构和群体性状的影响。结果表明：1)扬辐麦4号产量随着氮肥用量的增加呈先增加后降低的趋势；2)在中低种植密度条件下,穗数随着氮肥用量的增加呈增加趋势；在较高种植密度条件下,穗数随氮肥用量的增加表现为先增加后降低的趋势；3)氮肥用量为240 kg·hm-2,种植密度为300万株·hm-2时扬辐麦4号产量最高,穗数最多；4)成熟期茎蘖数和干物重随着氮肥用量的增加呈先增加后降低的趋势,随着种植密度的增加呈增加趋势。

Reasonable nitrogen level and planting density are better to explore the yield potential of new wheat varieties.To study the effects on Yangfumai 4 yield component and group structure,four nitrogen levels and four planting densities were set.Results show that with the increase of nitrogen amount,yield and spike increased first and then decreased in lower and medium planting density level,the spike number increased with the using of nitrogen fertilizer;in higher planting density level,the spike number first increase then decreased;in lower and medium planting density level,the spike number increased with the using of nitrogen fertilizer;in higher planting density level,the spike number first increase then decreased with the increase of nitro-gen fertilicer while the amount of nitrogen fertilizer is 240 kg·hm-2 and the planting density is at 300 million·hm-2 ,Yangfumai 4 is at its highest yield.
