[目的]为了研究播期、密度及氮肥运筹对淮麦21号产量和品质的影响,从而根据其品种特点确定适宜的栽培措施。[方法]采用二裂式裂区设计,进行播期、密度试验和氮肥用量及运筹试验。[结果]结果表明:播种期10月14日前后、基本苗密度240万/hm2、氮肥运筹5∶1∶2∶2及5∶1∶4时,淮麦21号的产量和品质都较好。[结论]该研究为淮麦21号的优质、高产、高效生产提供了理论依据。
[Objective] The research aimed to study the effects of sowing date, planting density and nitrogen fertilizer on the yield and quality of Huaimai 21, and to determine suitable cultivation measures according to the characteristics of its varieties. [Method] With the design of two - split split zone, sowing date, density test, nitrogen fertilizer dosage and operation test were conducted. [Result] The results showed that the yield and quality of Huaimai 21 were better when sowing date was around October 14, the basic seedling density was 2.4 million / hm2, nitrogen fertilizer operations were 5: 1: 2: 2 and 5: 1: 4 . [Conclusion] The study provided the theoretical basis for the high quality, high yield and high efficiency production of Huaimai 21.
