摘要:

对都安、崇左、阳朔和融安县四个不同种源黄花蒿的生长发育状况和生物量分配进行比较,结果表明:黄花蒿的生长旺盛期是在5月底至7月初,6月中旬为生长的高峰期,这段时期内应施以重肥; 不同种源黄花蒿各功能构件生物量平均值具有相同的规律:茎构件>叶构件>根构件; 都安种源的叶构件生物量和青蒿素含量均比其它种源的高,综合表现最优,是引种栽培的好种源。

Abstract:

In this paper,the growth and biomass allocation of Artemisia annua from Du'an, Chongzuo, Yangshuo and Rong'an were studied. The results are as follows:the growth of A.annua was the fastest from the end of May to early July,the peak of growth was in the middle ten days of June. In this period,more fertilizer should be applied; the mean values of all functional module biomass in different seed sources exhibited same regularity:stem modules>leaf modules>root modules; the seed source of A.annua in Du'an which leaf module biomass and artemisinin content were highest in all seed sources,was excellent.
