摘要
[目的]为新麦28的推广提供理论指导。[方法]在豫北地区采用裂区试验研究播期和播量对新麦28产量及其构成因素的影响,探讨小麦新品种新麦28的配套栽培技术。[结果]播期及其与播量的互作对新麦28产量的影响达显著水平;播期对新麦28农艺性状的影响达到显著水平。推迟播期后,新麦28的成穗数和产量均有所降低,而播量对其产量及产量构成因素的影响不显著。[结论]10月12日播种新麦28的最佳播量为150 kg/hm2,晚播(10月19日)的最佳播量为187.5 kg/hm2。
[Objective] The research aimed to provide theoretical basis for the popularization of strong gluten wheat variety Xinmai 28. [Method]The effects of different sowing date and planting density on the yield and its components of Xinmai 28 were studied in north areas of Henan Province by using split-plot experiment. [Result]Sowing date and its interaction with planting density had significant effects on the yield of Xinmai 28. And sowing date had significant effects on the agronomic traits of Xinmai 28. After the sowing date was postponed,the spike number and yield of Xinmai 28 decreased,but sowing date had no significant effect on the yield and yield components of Xinmai 28. [Conclusion]The suitable planting density of Xinmai 28 sowed on October 20 th was 150 kg / hm^2 and the suitable sowing date of Xinmai 28 sowed in October 19 th was187. 5 kg / hm^2.
