| 摘 要： | 以郑麦9023为材料,通过不同水肥耦合处理,研究了水肥耦合下小麦根系及根际微环境变化的差异.结果表明,在同一水分条件下,增施氮肥显著增加单位面积穗数,最终产量表现为施氮肥200 kg/hm2的处理＞施氮肥300 kg/hm2的处理＞不施氮肥的处理；同一氮肥处理下,灌水处理增加了单位面积穗数、穗粒数、千粒重和产量.从耦合...

| Abstract: | Using Zhengmai 9023 as expriment material,the effect of water and fertilizer coupling on roots and rhizosphere microenvironment of wheat were investigate.Applying nitrogen fertilizer could increase the number of spike significantly under the same water condition.The grain yield order of different nitrogen application treatment was 200 kg/hm2 > 300 kg/hm2 > control.Irrigation increased the number of spike,the grain number per spike,the biomass per 1 000 grains and the yield of wheat under the same nitrogen a... |
