| 中文摘要: |
| 为了解秸秆还田条件下不同施氮方式对冬小麦干物质积累和运转的影响，以商丘市夏邑县为
试验点，研究了玉米全部粉碎还田与6 种施氮方式相结合的栽培措施对国麦301 干物质积累和运转的影
响。结果表明，不同施氮方式对国麦301 干物质积累和转运有显著影响，其中对成熟期的干物质积累影响
最大。拔节期、孕穗期、开花期、成熟期的干物质积累随施氮量的增加均呈现一元二次曲线的变化趋势，其
最高干物质的施氮量分别为269.12、277.39、260.88、269.77 kg/hm2。成熟期干重、籽粒产量、花前同化物转
化率及贡献率均以N3 处理（施氮量262.5 kg/hm2）最高。 |

| In order to known the effect of the corn straw mulching plus nitrogen fertilizer on dry matter
accumulation and transportation in wheat‘ Guomai 301’，which was studied by 6 methods of nitrogen application in
Xiayi county of Shangqiu city. The results indicated that different nitrogen application methods had remarkable effect
on dry matter accumulation and transportation in“ Guomai 301”，and the largest influence on mature stage. Jointing
stage，booting stage，flowering period and mature period of dry matter accumulation were showing change trend of
unitary quadratic equation with the increasing of application rate of nitrogen，and the nitrogen rate of the highest dry
matter of the four fertility periods were 269.12 kg/hm2，277.39 kg/hm2，260.88 kg/hm2，269.77 kg/hm2，respectively.
They were the highest of mature dry weight，grain yield，transfer percentage of dry matter and contribute percentage
in N3 treatment（ 262.5 kg/hm2 N application） |
