莲(Nelumbo nucifera Gaertn.),为多年草本水生植物,既是艳丽的名花,又是重要的经济植物。莲也称荷花、莲藕,属睡莲科莲属;莲属共2种,我国种植的莲是其中的一种。人们根据不同的需要,长期进行人工选择,形成了现今的花莲、子莲、藕莲三种不同类型的品种。本实验对这三种类型的品种的主要经济性状进行了初步观察。 材料和方法 选有代表性的3个不同类型品种为观察材料:‘红千叶’为红花、半重瓣、色姿俱美的花莲品种;‘湖南泡’为高产、优质、中熟的藕莲品种;‘红建莲’为高产、优质的子莲品种。栽植于缸中,缸口径70厘米,高60厘米。1980年3月10日装藕田肥泥,装泥深度50厘米,其上10厘米灌水。每个品种栽一缸,每缸栽1支藕(取顶芽和其下1节间)。‘湖南泡’、‘红千叶’、‘红建莲’分别于4月9、12、17日移植。移植后3天观察一次,单缸花期每天观察一次,单朵花期1日观察3次。
(Nelumbo nucifera Gaertn.), A herbaceous aquatic plant for many years, is both a beautiful and famous flower and an important economic plant. Lotus also known as lotus, lotus root, is a genus of Nymphaeaceae; lotus genus 2 kinds of lotus plants in China is one of them. According to different needs, people make long-term artificial selection and have formed three different types of varieties, namely Hualien, Zilian and lotus root lotus. The experiment conducted preliminary observation on the main economic traits of these three types of varieties. MATERIALS AND METHODS Three representative varieties of cultivars were selected as observational materials: ’Chuanqian’ was a Hualien variety with safflower, semi-double petal and color appearance; ’Hunan bubble’ was a lotus with high yield, good quality and medium maturity Lotus varieties; ’Red Jianlian’ for high yield, high quality seed lotus varieties. Planted in the cylinder, cylinder diameter 70 cm, 60 cm high. March 10, 1980 loaded Outian fat mud, loading mud depth of 50 cm, 10 cm of water on it. Each species planted a cylinder, planted a lotus per tank (take the top bud and the next section). ’Hunan bubble’, ’red Chiba’, ’red Jianlian’ were April 9, 12, 17 transplant. Observed 3 days after transplantation, single-flowering observed once a day, single flowering observed on the 1st 3 times.
