摘要: [目的]旨在研究不同播期对荞麦产量的影响,筛选适合青海东部农区荞麦种植的时间,[方法]以苦荞黑丰1号品种为试验材料开展田间试验,测定了5个播种时间下生育期及其构成因素等对产量的影响。试验结果表明:随着播期的延长,苦荞“黑丰1号”的产量呈现出先上升后下降的趋势,且在A3处理时理论产量达到最高,为408.9kg/亩。随着播种期的推迟,苦荞“黑丰1号”的生育期呈现出缩短的趋势,且各个阶段也表现出不同的差异性;地上部农艺性状中的主茎分支数处理间差异显著;同时与产量相关的构成要素差异性明显,最终产量在A3处理时最高。

Abstract: Objectives: Aims to study the effects of different sowing dates on buckwheat yield; select the optimum time for buckwheat planting applied to the eastern farming areas of Qinghai.Methods: Field experiments were conducted by using tartary buckwheat “Heifeng1”; the influence of the yield determined by the growth period, and the components was tested, based on 5 different sowing time. The result showed a tendency that with the extension of the sowing date, the yield of tartary buckwheat “Heifeng1” first increased and then decreased; theoretically speaking, under A3 treatment, the yield reached the highest, 408.9 kg/mu. While, with the delay of sowing date, the growth period of tartary buckwheat “Heifeng1” showed a trend of shortening; different stages displayed different performances; and also there were significant differences in the number of main stem branches among the above ground agronomic traits; meanwhile, the differences in yield components were obvious. Under A3 treatment, therefore, the final yield reached the highest.
