摘要
对益母草 L eonurus artemisia(L our.) S.Y.Hu开展不同物候期的界定试验 ,研究不同播种期和收获期对益母草生物学性状、单位产量和总生物碱含量影响的表现效应。结果如下 :1)低温春化处理促进秋播或冬播的益母草抽苔和开花。 2 )播种期的温度决定着益母草种子的出苗期 ,播种期和收获期决定着益母草的单位产量 ,建立了能常年供应鲜益母草原料的播种期和收获期。 3)播种期和收获期的界定对益母草总生物碱含量的影响 ,与播种期的温度和益母草生长周期长、短密切相关。
To study the phenological influence on the growth of Leonurus artimisia (Lour.) S.Y.Hu, to obtain an optimum yield of total alkaloid per unit area for the purpose to provide the fresh herbal drug all the year round.The biological characteristics for the sprouting and blooming of L.artimisia were investigated after sowing and harvesting at 8 different periods of the seasons and the yield of total alkaloids determined. Results showed that vernalization at low temperature can promote sprouting and blooming of L.artimisia sown in Autumn and Winter.The temperature during sowing is the main determining factor influencing the growth of the plant and yield of alkaloids.
