摘要:

为明确栽培措施对优质专用小麦品种‘渭麦9号’产量及品质的影响,开展播期、播量、氮肥三因素试验。于2021—2022年在田间采取裂区和随机区组试验设计,施氮量分别为210 kg/hm2 (A1)、105 kg/hm2 (A2)、不施肥(A3),播期分别为10月2日(B1)、10月18日(B2)、10月27日(B3),播量分别为180×104 苗/hm2 (C1)、270×104 苗/hm2 (C2)、360×104 苗/hm2 (C3)。结果表明:氮肥施入量对产量影响不显著,播期和播量对产量影响显著。‘渭麦9号’在10月18日,270×104 苗/hm2和360×104 苗/hm2均可以达到合理的群体结构,从而达到高产水平。以氮肥用量105 kg/hm2、播期10月18日、播量360×104 苗/hm2时,产量最高。相同施肥和播量水平下,以10月2日的品质最佳,除最大拉伸阻力外均达到(中)强筋小麦标准。本次试验结果表明,适期播种可以达到‘渭麦9号’的最高产量,适期早播可以提高其品质性状。

Abstract:

To explore the effects of sowing date, planting density and nitrogen application on population structure and grain quality of high-quality wheat variety ‘Weimai 9’, a split-plot and randomized block design was adopted in the field from 2021 to 2022. The nitrogen application rates were 210 kg/hm2 (A1), 105 kg/hm2 (A2) and 0 kg/hm2 (A3), and the sowing dates were October 2 (B1), October 18 (B2) and October 27 (B3), the seeding rates were 180×104 seedlings/hm2 (C1), 270×104 seedlings/hm2 (C2) and 360×104 seedlings/hm2 (C3). The results showed that the effect of nitrogen application rate on yield was not significant, but the effect of sowing date and planting density on yield was significant. On October 18, seeding rates of 270×104 seedlings/hm2 and 360×104 seedlings/hm2 of ‘Weimai 9’ could reach a reasonable population structure, so as to achieve high yield level. When the amount of nitrogen application was 105 kg/hm2, the sowing date was October 18, and the seeding rate was 360×104 seedlings/hm2, the yield was the highest. Under the same fertilization and sowing rate levels, the quality of sowing date of October 2 was the best, which reached the standard of (medium) strong gluten wheat except the maximum tensile resistance. The results of this experiment showed that the highest yield of ‘Weimai 9’ could be obtained by sowing at an appropriate time, and early sowing at the right time could improve its quality traits.
