Effects of different fertilization schemes on the quality of cut lily under the condition of frame-type soilless culture

Abstract

Studies on fertilization methods for cut lilies have resulted in varying opinions on whether and when fertilization should be applied during lily cultivation, and the amount and rate of fertilization. The purpose of this paper is to study the effect of different fertilization schemes on the quality of cut lily, seek the most suitable fertilization scheme for the growth and development of cut lily, and provide a scientific theoretical basis for rational fertilization in the production of cut lily. The mainstream cut lily varieties 'Conca d'Or', 'Sorbonne' and 'Siberia' were used as experimental materials to study the effects of different fertilizers and fertilization methods on the growth and quality of lilies. The results showed that A1 (without basal fertilizer) germinated the earliest and had the highest plant height in the vegetative growth period. A2 (nitrate nitrogen compound fertilizer 2 g/plant as basal fertilizer treatment) budded the earliest. The overall best quality of ‘Conca d'Or' cut flowers is A1B3 treatment (none basal fertilizer, YaraMila Compound fertilizer 2 g/plant as topdressing), 'Sorbonne' is A2B3 treatment (Yangfeng nitrate nitrogen compound fertilizer 2 g/plant, YaraMila Compound fertilizer 2 g/plant), 'Siberia' is A2B1 treatment (nitrogen compound fertilizer 2 g/plant as base fertilizer, none top dressing); and A2B1 treatment is ranked at the forefront in the ranking of all indicators of the three varieties. In conclusion, excessive fertilization significantly reduced the quality of cut lilies. One-time fertilization can meet the nutritional needs of high-quality cut lily, of which A2B1 treatment (nitrate nitrogen compound fertilizer 2 g/plant as base fertilizer, none top-dressing) is the combination with lower cost and the best effect in one-time fertilization scheme, suitable for cut lily promotion and use in production.
