为探讨国审小麦新品种周麦28的配套栽培技术,采用裂区试验研究了播期和种植密度对周麦28产量及其构成因素的影响。结果表明,播期和种植密度及其互作对周麦28产量的影响达显著水平;播期和种植密度对产量构成因素的影响达显著水平;周麦28的适宜播期在10月10~15日内,周麦28的最佳播量在270万/hm2左右,但可根据地力条件和整地质量适当调整。
In order to investigate the cultivation techniques of the national wheat trial Zhoumai 28, the effects of sowing date and planting density on the yield and its components of Zhoumai 28 were studied by split-plot experiment. The results showed that the effects of sowing date, planting density and their interactions on the yield of Zhoumai 28 reached significant level. The effects of sowing date and planting density on yield components were significant. The suitable sowing date of Zhoumai 28 was between October 10 and 15 Days, Zhou Mai 28 the best sowing at 2.7 million / hm2 or so, but according to the conditions of land conditions and the quality of land preparation appropriate adjustments.
