摘要
研究了保护地栽培条件下野生蔬菜蒌蒿的生长发育特点及其相应调控技术。结果表明 ,保护地栽培改变了蒌蒿的物候期 ,提早和延长了蒌蒿的采收供应期 ,同时个体生长受到一定的影响 ,茎秆纤细、柔弱。通过调节扦插密度和采收期 ,可以控制保护地蒌蒿群体大小和个体生长量 。
The growth characteristics and corresponding regulation techniques of Artemisia selengensis Turcz.in protected cultivation were studied.The results showed that the phenophase of Artemisia selengensis Turcz.was changed,the reaping time was earlier than expected and the supplying period was prolonged in protected cultivation.However,the plant individual growth was affected.Its stem was thin and tender.Population size and individual increment of Artemisia selengensis Turcz.could be controlled through regulating cutting densities and reaping time.Appropriately expanding cutting densities and delaying reaping are important culture techniques to achieve high yield and good quality of Artemisia selengensis Turcz.
