以4个欧洲水仙品种为试材,采用设施地栽、设施盆栽和露地栽培3种种植方式,对其物候期、物候期与总积温的关系、园艺性状、母球周径增长量及种球繁殖系数进行比较研究。结果表明:设施栽培与露地栽培模式相比,欧洲水仙品种物候期提前,花期延长,种球繁殖系数提高;设施栽培的欧洲水仙品种物候期与总积温呈显著线性关系,露地栽培呈显著指数关系;设施地栽较设施盆栽与露地栽培,欧洲水仙品种植株高、叶片长、花葶高、母球周径增长量及种球繁殖系数表现较好。因此,采用设施种植有利于欧洲水仙的规模化生产。
Four European narcissus cultivars were used as materials to study the relationship between their phenological stage, phenological stage and total accumulated temperature, horticultural traits, growth rate of cusps and seed bulbs Breeding coefficient for comparative study. The results showed that the phenophase of European narcissus was earlier, the flowering period was prolonged, and the propagation coefficient of bulbs was increased compared with that of open field cultivation. The phenological period of European narcissus cultivars showed a significant linear relationship with total accumulated temperature and the open field cultivation showed a significant exponential relationship Planting facilities were compared with potted plants and open field cultivation facilities. European Narcissus cultivars had higher plant height, longer leaves, higher flower height, better growth of cystern circumference and higher coefficient of propagation of bulbs. Therefore, the use of facilities planting is conducive to the large-scale production of European narcissus.
