在近几年流行于世的洋兰中,大花蕙兰的供应量和价位始终居高不下。也就是说,它有很大的市场潜力,值得人们下大力去研究和生产。试验材料和方法1.材料及来源大花蕙兰常见栽培和用作杂交亲本的约有20种。1996年自清华大学引进两个品种(最初从日本引入),即‘索非亚’和‘梦露’,前者为中小花型,砖红色,后者为大花型,粉红色。1997年自广州、深圳引进2号、5号和6号,2号为大花型,浅绿色,下萼边缘有一道玫瑰红色痕迹;5号为大花型,粉红色;6号为大花型,黄色。其生长发育主要以连续三个年周期的观察记录为依据,结合气象观测分析,总结出年生长发育规律。温湿度因子是根据长春仪表厂生产的自计钟 QXZ 测出的数据。2.实验方法组培繁殖法春季用消毒的利刃将长3～10厘米的嫩芽从母株上切下,剪去上部叶片,留长为2～4厘米,并把最外面的1～2
In recent years the prevalence of ocean blue, Cymbidium supply and price remains high. In other words, it has great market potential, it is worth undergoing research and production. Test materials and methods 1. Materials and sources Cymbidium cultivated and used as hybrid parents about 20 species. In 1996, Tsinghua University introduced two varieties (originally introduced from Japan), namely ’Sofia’ and ’Monroe’. The former is small and medium-sized, with brick red and the latter with large flowers and pink. 1997 from Guangzhou, Shenzhen, the introduction of No. 2, No. 5 and No. 6, No. 2 for large flowers, light green, with a red rose scarlet edge of the lower calyx; 5 large flowers, pink; Type, yellow. Its growth and development are mainly based on observation records of three consecutive years, combined with meteorological observation and analysis, summed up the law of annual growth and development. Temperature and humidity factor is based on the Changchun Instrument Factory production meter QXZ measured data. 2. Experimental methods Tissue propagation method Spring disinfection of the blade will be 3 to 10 cm long buds cut from the mother plant, cut the upper leaves, leaving the length of 2 to 4 cm, and the outermost 1 to 2
