玉米无膜浅埋滴灌水肥一体化模式分期追肥对产量的影响

2020年在内蒙古通辽市2个高效节水核心示范区开展无膜浅埋滴灌水肥一体化模式下耐密晚熟型玉米品种各生育时期不同追肥比例分期追肥试验。结果表明,在拔节期:大口期:抽雄前:吐丝期:灌浆期(2:5:1:1:1)进行追肥玉米产量较高。

Effect of topdressing by stages on Maize Yield under the integrated mode of irrigation and fertilizer with shallow mulch without film

In 2020, the experiment of different topdressing by stages in different growth stages of Late Maturing Maize Varieties with dense tolerance under the mode of no film shallow burying drip irrigation and fertilizer integration was carried out in two high efficiency and water-saving core demonstration zones in Tongliao City, Inner Mongolia. The results showed that the yield of the topdressing by stages maize was higher in the jointing stage: the big mouth stage: before the male pulling: the spinning stage: the filling stage (2:5:1:1:1:1).
