Increasing N application amount and/or the ratio of topdressing N after elongation stage could raise grain yield, protein content, wet gluten content, sedimentation, falling number, development time and stability time. To produce strong-gluten and medium-gluten wheat, the suitable ratio of basis : tillering : elongation : booting N fertilizer was 3:1:3:3or5:1:2:2 with 180 - 240 kg N ha-1. To produce weak-gluten wheat, the ratio of basis : tillering : elongation N fertilizer should be 7 : 1 : 2 with 180 kg N ha-1 and 240×104 ha-1 seedlings.展开更多
