唐菖蒲(Gladiolus gangavensis Houtt.)是鸢尾科的球根花卉,繁殖法分播种和分球茎两种,在生产栽培上一般均用后者。 作者在1951年于复旦大学花卉试验场和1959年在大连地区,先后对一般品种的唐菖蒲球茎进行以下几种机械法处理的繁殖试验,目的在提高分球茎法的繁殖系数:(1)对切:剥去球茎外层褐色带纤维质的外皮,其顶部显露出两个略带三角形的顶芽,用刀片在两顶芽间把球茎平均对切成两块;(2)除顶芽:把球茎顶部两三角形顶芽用刀刻除;(3)对切并除顶芽:即从对切处理后的球茎,再按除顶芽法剥除顶芽(在进行以上三种处理后,伤口均用草灰涂抹,借以防止腐烂)。(4)对照:球茎不经处理,完整地栽入土中。 以上四种处理法各用球茎15个(其中对切和对切并除顶芽则均按半个球茎计算),分
Gladiolus gangavensis Houtt. Is a bulbous flower of the Iridaceae, which is divided into two types according to propagation and sub-bulb propagation. The latter is generally used in production and cultivation. In 1951 Fudan University flower test site and 1959 in Dalian, the author has carried out the following varieties of gladiolus corm on the following mechanical processing of breeding experiments, the purpose is to improve the coefficient of multiplication bulbs method of propagation: (1) Cut: stripped of the outer layer of brown stem with fibrous outer skin, the top reveals two slightly triangular top buds, with a blade between the two buds average corm cut into two; (2) In addition to the top bud: (3) cutting and removing the top bud: that is, after cutting the treated stem, then removing the top bud by removing the top bud method (after performing the above three treatments, The wounds were smeared with straw to prevent decay). (4) Control: Bulbs untreated, planted into the soil intact. The above four kinds of treatment methods each with 15 corms (which cut and cut and in addition to the top buds are calculated by half a bulb), points
