摘    要:为了解打顶对甜荞产量的影响,进行了晋荞麦3号打顶栽培试验。结果表明:与不打顶(CK)相比,盛花期主茎、侧枝顶端均打的甜荞产量提高17.9%;株高降低12.8cm;一级分枝增加0.8个、二级分枝增加3.6个;单株花减少297.5朵,单株粒数增加41.6粒,单株结实率提高9.2个百分点,单株粒质量提高53.57%。

关 键 词:甜荞  打顶  产量  产量构成因素

Abstract:The effect of topping on the yield of buckwheat variety Jinqiaomai 3 was investigated.The results showed that the grain yield increased by 17.9% when the main stem and side branches were all topped at full flowering stage,compared to CK(not topping).Topping could reduce the plant height by 12.8 cm,increase the first and secong branch number by 0.8 and 3.6,decrease the flower number by 297.5,increase the seed number by 41.6,increase the spikelet fertility by 9.2 percent points and increase the grain weight by 53.57% per plant.
Keywords:common buckwheat  topping  yield  yield componets
