金荞麦在北京地区引种栽培，生长期１８０天左右，株高１．３－１．５米，分枝６－１６个。地上部枯萎在霜冻前，同期植物各部位的干物质积累重及有效成分含量都达到了高峰，此时期为最佳采收期，收获期各部位双聚原矢车菊甙元含量，根７．４－８．７％，茎３．９－４．３％，叶２．９－３．４％，花３．８－４．５％，地下部根与地上部茎、叶、花之比为１：２．９～１：３．４，全草具有较好的开发利用价值。 Golden buckwheat introduced in Beijing cultivation, growth period of 180 days, plant height 1.3-1.5 meters, branches 6-16. Before the frost, the dry matter accumulation weight and the active ingredient content of all parts of the plant reached the peak during this period, which was the best harvesting period. The content of the bilum procaridin in each part of the harvest period, .4-8.7%, stems 3.9-4.3%, leaves 2.9-3.4%, flowers 3.8-4.5%, roots and shoots aboveground stems, leaves, flowers Ratio of 1: 2.9 ~ 1: 3.4, the whole plant has a good value of development and utilization.
