河北滨海地区地被菊引种栽培试验初报

A Preliminary Report on Introduction and Cultivation of Ground-cover Chrysanthemum in Hebei Coastal Areas

从南京和北京引进13种地被菊种苗，在河北滨海地区进行试种，观察其生物学特性、适生性、物候期、抗蚜性及耐盐性等的变化。结果表明：所引进的13个地被菊品种基本能适应河北滨海地区的自然气候条件，除金陵玉宇长势较弱、属于小花型地被菊、适宜盆栽种植外，其他品种均能在河北滨海地区田间正常生长、发育，株高、冠幅、花径基本达到原产地标准，重瓣性、花色表现正常，开花、繁殖系数高，露地越冬，萌芽早、枯黄晚，并表现出很好的适应性和抗逆性，经济性状良好。其中，北京种源地被菊品种花期早，适应性、耐盐性和越冬性等表现较佳；南京种源地被菊品种花期为10~11月，花色艳丽，花量大、自然成丛、覆盖度好，适应性和越冬性较好。除金陵玉宇外，所引进的地被菊品种均适宜河北滨海地区田间栽植，可用于城市绿化。

13 varieties of ground-cover Chrysanthemum introduced from Beijing and Nanjing were selected as observation materials to plant. Agronomic traits,adaptability,phenological phasen,insect resistance and salt tolerance were investigated under field condition in test field of Institute of Coastal Agriculture. The results showed that the height,canopy,flower diameter of all the varieties reached the standards in place of origin and the multiple corolla and the flower color showe d nor mal. Ground-cover Chrysanthemum showed very good adaptability,resistance and good economic characters in Hebei coastal areas. The Beijing plant varieties such as Golden Olympic Games,August Snow,Red Sun have the appropriate plant height,early blooming,strong adaptability. The Nanjing plant varieties such as Jinling Crown,Jinling Starlight,Jinling Zhihe,Zhongshan Dwarf Yellow, Zhongshan Purple Lotus have large amount of plant shape and gorgeous color, abundant flowers and peculiar pattern. These varieties are available application in Hebei coastal areas.
