欧洲水仙设施栽培与露地栽培比较研究

Comparative Study on Protected Cultivation and Open Cultivation of Narcissus spp.

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。

Taking four varieties of Narcissus spp.as test material,by using the land plant in facility,potted plant and open cultivation,phenophase,the relationship between phenophase and total accumulated temperature,horticultural traits,increase of bulb perimeter and bulb number of 4varieties of Narcissus spp.were analyzed.The results showed that Narcissus spp.planted in facility possessed the following unique characteristics,such as advance each phenophase,extend the flowering period and high rates of propagation.Significant linear relationship was proven between phenophase and total accumulated temperature under protected cultivation,and significant exponential relationship was shown under open cultivation.Narcissus spp.varieties had the best performance in plant height,leaf length,stem height,increase of bulb perimeter and bulb number under the land plant in facility,which compared with potted plant and open cultivation.The culture of Narcissus spp.under protected facility was useful to the scale producing.
