摘要: 2014-2016年以宁荞1号为供试品种,研究了不同密度对荞麦(Fagopyrum esculentum Moench.)农艺性状、受精结实率及产量的影响。结果表明,在生育期降雨较多的2014年,随密度的增加,株高增高,茎粗变粗,主茎节数增多,单株粒数、单株粒重和千粒重均呈下降趋势,受精结实率呈下降趋势,产量呈增加趋势;在降雨较少的2015和2016年,随密度的增加,主茎节数、单株粒数、单株粒重及千粒重随着密度增加呈先增加后降低的趋势,受精结实率随着密度的增加呈下降趋势,产量呈先增加后下降的趋势。从增产的角度看,荞麦在宁南山区的适宜播种密度为6万株/667 m2

Abstract: Buckwheat variety Ningqiao 1 was selected as material to study the effects of different planting densities in different years on agronomic traits, seed setting rate and yield of buckwheat. The results showed that in the 2014 growth season with more rainfall, with the increase of density, the plant height, stem diameter and main stem section number increased; the seed number per plant, grain weight per plant, thousand seed weight, and seed setting rate showed a trend of decrease; and the yield increased. In the 2015 and 2016 growth season with less rainfall, with the increase of density, the number of main stem section, seed number per plant, grain weight per plant and thousand seed weight increased at first, then decreased; the seed setting rate declined; and the yield increased at first, then decreased. To get a high yield, the planting density of 60 000 plants/667 m2 is suitable for buckwheat planting in the southern mountains area of Ningxia.

Key words: buckwheat(Fagopyrum esculentum Moench.), planting density, agronomic trait, seed setting rate, yield
