| 摘 要： | 本试验采用大田随机区组设计研究了基施氮肥用量对皖麦36生长及产量的影响.结果表明:基施纯氮量在184kg/hm2范围内,增加氮肥用量能够促进皖麦36主茎叶片数、伸长节数、株高等生物学产量提高和有效穗数、穗实粒数增加.当基施纯氮用量超过184kg/hm2时,植株生长过旺,产量下降.因此,皖麦36基施纯氮应控制在184kg/hm2以内.

| Abstract: | By random design,effect of nitrogen fertilizer on growth and yield of WanmaiNo.36 wheat were studied.The results showed that: growth of WanmaiNo.36 was effectively promoted,the leaf number and height and biology yield increased,the ear and grain and weight increased under increaseing nitrogen fertilizer among amount of nitrogen fertilizer 184kg/hm2.The yield and growth were decreased when the nitrogen based fertilizer over 184kg/hm2 as increase nitrogen fertilizer.The optimum fertilization amount of nitrogen fertilizer for WanmaiNo.36 wheat is 184kg/hm2. |
