氮肥后移促进受渍夏玉米根系形态恢复和提高花后光合性能OA北大核心CSCDCSTPCD
Postponed nitrogen application enhances root morphology recovery and photosynthetic characteristics of summer maize waterlogging stressed at seedling stage
江淮地区受梅雨影响,玉米苗期易发生渍害,如何通过合理运筹氮肥达到减灾效果值得研究.以夏玉米品种'隆平206'为试验材料,研究不同氮肥运筹方式[氮肥全部基施(N1)、基肥70%+拔节肥30%(N2)、基肥50%+拔节肥50%(N3)和基肥30%+拔节肥50%+大喇叭口肥20%(N4)]对苗期受渍夏玉米根系形态和花后光合性能恢复的影响,以期为苗期受渍夏玉米合理施肥提供理论依据.结果表明,苗期渍水7 d抑制根系生长,根重、根长度、根表面积和根直径均显著…查看全部>>
Maize is one of the main summer crops in Anhui Province. However, maize production in this region is often sub-jected to waterlogging stress at seedling stage. Nitrogen (N) is a key nutrient that influencing growth, yield and quality of maize, but what role it plays in relieving waterlogging stress on summer maize remains unclear. Thus field experiments were carried out to determine the effect of N application on the recovery of root morphology and photosynt…查看全部>>
