摘    要:以4个高产冬小麦品种为材料,在河南浚县农业科学研究所超高产攻关田研究了不同行距配置对小麦群体质量及产量的影响.结果表明,豫麦49-198、周麦22和矮抗58群体总茎数、单株成穗数、叶面积系数、干物质积累量均以宽窄行种植模式较高,而偃展4110则以等行距种植模式较高,籽粒产量及其构成因素亦表现出相似的趋势.因此,实际生产中,应根据不同穗形小麦品种选择合适的行距配置以提高产量.

关 键 词:冬小麦  行距配置  群体质量  产量

Abstract:In order to investigate effects of different row spacing on population quality and yield in winter wheat, four high-yielding wheat cultivars with different spike types,Yumai 49-198,Zhoumai 22,Yanzhan 4110 and Aikang 58 were cultivated under field condition. The experiments were carried out at the experimental farm of Xunxian Agricultural Science Institute. The results indicated that,the population total stems number,spikes per plant,leaf area index and dry matter accumulation of Yumai 49-198 and Zhoumai 22 and Aikang 58 were relatively higher under narrow and wide row spacing cropping patterns,however,Yanzhan 4110 was relatively higher under equation row spacing cropping patterns. For different row spacing cropping patterns,when under narrow and wide row spacing cropping patterns,the grains yield and its constructed component were relatively upper of Yumai 49-198 and Zhoumai 22 and Aikang 58,whereas for Yanzhan 4110,the grains yield and its constructed component were relatively greater under equal row spacing cropping patterns. Thus,in practice, suitable row spacing should be determined according to the different spike types to increase grain yield.
Keywords:winter wheat  row spacing  population quality  grain yield
