17个蝴蝶兰品种在广州和林芝的种植表现

The planting performance of 17 Phalaenopsis varieties in Guangzhou and Linzhi

调查了17个蝴蝶兰品种在广州和林芝两地种植的株高、株幅、叶数、花色等15个性状。结果表明,两地间同一品种的花色一致,且抽梗率和开花率两地间差异不显著;与林芝地区相比,各品种的花枝长、花朵数和花径在广州表现更好,分别平均多出21.0 cm、3.1朵和1.7 cm,但花梗数表现稍差,比林芝平均少0.2个;就始花期而言,两地间除个别品种一致外,在广州平均比林芝早10～60 d;冬、春季节,林芝的气温比广州低很多,蝴蝶兰容易发生冻害,应加强保温。

15 characters of plant height, plant width, leaf number, flower color, etc. on 17 Phalaenopsis varieties in Guangzhou and Linzhi were observed and investigated. The results showed that the colour of the same variety was consistent and there was no significant difference in stalk rate and flowering rate between Guangzhou and Linzhi. Compared to Linzhi, the flowering branch, flower number and flower diameter in Guangzhou were 21.0 cm, 3.1 flowers and 1.7 cm larger than that of Linzhi, but the peduncle number in Guangzhou was 0.2 less than Linzhi. On the terms of early flowering period, it was 10-60 days earlier than Linzhi except that individual varieties were consistent between two places. In winter and spring, Phalaenopsis plants were easy occurrence of cold injury because the temperature in Linzhi was much lower than Guangzhou, thus the measures of heat preservation should be strengthened in Linzhi.
