摘要
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,以苦荞‘黑丰1号’为试验材料开展田间试验,测定5个播种时间下生育期及其构成因素等对产量的影响。结果表明:随着播期的延长,苦荞‘黑丰1号’的产量呈先上升后下降的趋势,且在A3处理时理论产量达到最高,为6133.5 kg/hm^2。随着播种期的推迟,苦荞‘黑丰1号’的生育期呈缩短的趋势,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枝数处理间差异显著;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。
The paper aims to study the effects of different sowing dates on buckwheat yield,to select the optimum time for buckwheat planting applied to the eastern farming areas of Qinghai.We conducted field experiments by using tartary buckwheat‘Heifeng 1’,and tested the influence of growth period and components on yield at 5 different sowing times.The results showed that:with the postponing of the sowing date,the yield of tartary buckwheat‘Heifeng 1’first increased and then decreased,and the highest theoretical yield was achieved under A3 treatment(6133.5 kg/hm^2);while,with the delay of sowing date,the growth period of tartary buckwheat‘Heifeng 1’showed a trend of shortening;different stages displayed different performances;and also there were significant differences in the number of main stem branches of the above ground agronomic traits among different treatments;meanwhile,the differences in yield components were obvious;the final yield reached the highest under A3 treatment.
