1.采收时间。通常在夏秋季采收。灯盏花有效成分含量最高的是叶片,其有效成分含量为初花期最高,盛花期次之,种子成熟期最低,因此,初花期采收灯盏花最为合理。2.采收方式。灯盏花属全草类药材,传统采收是连根部一起采挖,但由于根部有效成分灯盏花素含量低下,同时采挖后杂质含量较多,因此,人工栽培条件下常通过采割的方式采收。采收前在灯盏花苗长至20厘米左右高 Harvest time Harvest usually in summer and autumn. Erigeron is the highest active ingredient content of leaves, the active ingredient content of the highest initial flowering, full bloom, followed by the lowest seed maturity, therefore, early flowering erigeron harvest most reasonable. 2. Harvest methods. Erigeron is a whole herb medicine, the traditional harvesting is even with the roots excavation, but due to the root active ingredient Breviscapine content is low, while digging more impurities, therefore, under artificial cultivation conditions often by cutting way Harvest. Before harvest, the erigeron seedlings grow to about 20 centimeters tall
