摘要: 通过大田试验研究了不同密度和播期对大麦(Hordeum vulgare L.)品种鄂大麦263产量相关性状的影响。结果表明,播期、密度对鄂大麦263产量均有显著影响,且主要通过调控有效穗数对产量产生影响。鄂大麦263生产上实现高产的栽培技术方案为前期促分蘖、中期保成穗、后期充分灌浆,基本苗以240万苗/hm2为宜,播期以10月下旬为宜。

Abstract: The effects of planting densities and sowing dates on yield related traits of barely(Hordeum vulgare L.) variety Edamai 263 were investigated by field test. The results showed that planting density and sowing date had great effects on grain yield. And the effective tiller, regulated by planting density and sowing date, was the major factor that mostly influenced the yield of Edamai 263. To achieve high yield, the strategy should be raising the number of tiller, ensuring the panicle rate and grain filling. Based on the results, the suitable density was 2 400 thousand seedlings per hectare and the suitable sowing date was in late October.

Key words: barely(Hordeum vulgare L.), Edamai 263, sowing date, planting density, grain yield
