摘要: 研究了总施氮量20 kg/hm2的条件下,氮肥基追比对不同穗型小麦品种产量与品质的影响.结果表明,增加追氮比例产量增加,品质改善,但不同穗型品种之间存在差异.就多穗型品种而言,少施底氮,重施追氮,产量增加较多,形成时间、评价值及曲线面积等品质指标明显改善;大穗型品种随追氮比例增大品质有所改善,但幅度较小,重施底氮,少量追氮,产量较高.试验结果显示,多穗型品种以氮肥基追比5:5或3:7为宜;大穗型品种以7:3为宜.

Abstract: An experiment is carried out that effect of N application at different rates on grain yield and qual-i ty of two wheat varieties under the totaLpure N 240 kg/hm2.The results indicate that increasing N application rate can enhance grain yield and quality but there are different between two wheat varieties.Little base N and more application N at jointing stage increase grain yield and improve development time, value and curve area sig-nificantly for mul-i spike type wheat variety.Increasing N application has little effect on grain yield of large-spike variety.Keeping more base N and little application N is benefit for large-spike variety increasing grain yield and improving quality.Considering grain yield and quality, base N 50% and application N 50% or base N 30% and application N 70% is suitable for mul-i spike variety.In the meantime base N 70% and application N 30% is suitable for large-spike variety.

Key words: Ratio of base N and application N, Wheat, Spike type, Grain yield, Quality
