不同播种期对黄花蒿生长发育特性的影响

为了探索黄花蒿双季栽培的可行性,对不同播种期黄花蒿的生长发育特性进行了研究.结果表明:黄花蒿春、夏、秋三季均可播种,春、秋季播种的在8月下旬花芽分化,夏季播种的在9月中旬花芽分化.春季播种黄花蒿在6月上旬进入营养生长旺盛期.夏季播种黄花蒿在8月上旬进入营养生长旺盛期,由于营养生长期短,植株矮小,叶产量低.秋季播种黄花蒿在第2年5月上旬进入营养生长旺盛期,比当年春季播种的早1个月.

The Effect of Different Sowing Periods on Developmental Characteristics of Artemisia annua L.

In order to explore the feasibility of double-cropping A rtemisia annua L.the developmental characteristics of Artemisia annua L.in different sowing periods were studied.The results show that the Artemisia annua L. could sow in spring,summer and autumn.The Artemisia annua L. sowed in spring or autumn will differentiate flower buds in late August and the Artemisia annua L. sowed in summer will differentiate flower buds in middle September.The vigorous vegetative period of Artemisia annua L. sowed in spring and summer was in early June and early August,respectively,but their leaf yield was low for the reasons that vegetative period was short and plant was dwarf.The vigorous vegetative period of Artemisia annua L. sowed in autumn was in the coming early May,which is one month earlier than the vigorous vegetative period of Artemisia annua L.sowed in the coming spring.
