播期与品种对荞麦生长发育及产量的影响

The Influence of Varieties and Sowing Date on Buckwheat Growth and Yield

[目的]研究播期与品种对荞麦生长发育及产量的影响。[方法]研究3种播期水平,4种品种下荞麦生长和产量的变化。[结果]随着播期的延迟,荞麦生育时期延迟,单株鲜重呈下降趋势,成熟期单株(根、茎、叶)干物质重量、株高、主茎节数、主茎分枝、单株粒数、单株粒重、千粒重亦呈下降趋势。B1与B2之间产量差异不显著,B4与B3相比增产极显著。[结论]该研究为荞麦高产栽培品种选择及适期播种提供了科学依据。

[ Objective] To study the influence of sowing date and varieties on buckwheat growth and yield. [ Method] The buckwheat growth and yield were studied under three level of sowing date, four varieties. [ Result ] As the detention of sowing time delay, buckwheat growth pe- riod was delayed correspondingly, fresh weight per plant, dry matter weight and plant height of mature plant, etc were on the decline. No sig- nificant difference between B1 and B2 production. B4 production increased significantly compared with B3. [ Conclusion] The study offered a scientific basis for buckwheat high - yielding varieties selection and suitable sowing.
