不同施肥水平对东方百合鳞茎糖分积累规律研究

Study on Bulb Sugar Accumulation of Oriental Lily at Different Fertilizing Level

以荷兰进口的东方百合杂种系Sorbonne为材料,选用青海大学高原花卉研究中心多年筛选的自配三号营养配方,研究了4种施肥水平下东方百合生长期间鳞茎还原糖及可溶性糖积累及变化规律。结果表明:100%和50%2种施肥水平下鳞茎还原糖的积累显著高于其它2种施肥水平(P<0.05);而200%、150%、50%施肥水平下鳞茎可溶性糖含量显著高于100%(P<0.05)。因此,认为50%施肥水平对切花生产及鳞茎繁育来说是最经济的。

Selected oriental hybrids（Sorbonne） as material from Holland, No. 3 nutrition supply from Plateau Flower Research Center of Qinghai University to study the changes of bulb sugar accumulation of oriental lily at different fertilizer level during the growing stages. The results showed that the fertilizer level of 100% and 50% were high significantly than that of 150% and 200% on bulb reducing sugar aeeumulation（p〈0. 05）; the fertilizer level of 200%, 150% and 50% were high significantly than that of 100%（p〈0. 05）. From the viewpoint of fresh flowers and bulb breeding, the most economical fertilizer level was 50%.
