摘要:
针对扦插过程中不同菊花品种的生根速度不一致问题,以14个观赏大菊品种进行扦插试验,测定径粗、根长、根系直径、根数等的动态变化,研究不同品种根系生长规律。对大菊品种扦插生根试验研究表明,不同菊花品种的生根速度不一致,有的品种扦插后只需4~8 d即能开始生根,有的品种却要10~12 d才能开始生根,生根快和中速的品种,在4~8 d内,生长速率逐渐提高,扦插后9~12 d生长速率陆续处于顶峰;生根慢的品种在扦插后13~14 d 生长速率出现高峰。生根慢的品种生长速率峰明显低于生根快和中速的品种。所有大菊品种在出现生长峰期后,生长速率逐渐下降,然后生长速率在0.25 cm/2 d附近趋于集中。在根系生长过程中,根系直径越大,径粗越粗,对植株的生长越有利。
