| 摘 要： | 【目的】针对温度对花卉种苗生产的影响,探寻设施花卉种苗高效可持续生产方式。【方法】以矮牵牛、三色堇播种繁殖种苗为试验材料,设计了3种夜温处理进行种苗生产,测定种苗生产周期、种苗质量、加温能耗和人力投入等。【结果】表明矮牵牛YS1处理生产周期比对照长3d,生长期加温能耗降低3%,种苗生长更紧凑,质量有较为明显的提高,但生产成本略有提高,冬季将夜间温度降低2℃进行矮牵牛生产是可行的;三色堇生长周期比对照长8~17d,生产成本增加较多,降低夜间温度的生产方式并不适用于三色堇种苗生产。【结论】降低冬季夜间加热温度进行种苗生产的方法,需要根据实际情况决定是否可以采用。

| Abstract: | Objective]This study aimed to find the effect of different night temperatures on the production of plug seedlings,then explore efficient and sustainable production methods.Methods]The plug seedlings of Petunia hybrida and Viola wittrockiana were used as the test materials.Three night-temperatures were used to treat the plug seedlings,then the production cycle and quality of plug seedlings,energy consumption of heating,and human input were measured.Results] Compared to control,after YS1 treatment,the production cycle was 3 days longer,and the energy consumption of heating decreased by 3％,and the plug seedlings were more compact,and the quality increased significantly,but the production cost rose slightly.So decreasing night temperature by 2 ℃ was feasible to produce the plug seedlings of P.hybrida in winter.But for V.wittrockiana decreasing night temperature caused the increase in production cycle by 8-17 days compared to control,and the production cost rose substantially.So decreasing night temperature was not suitable for producing the plug seedlings of V.wittrockiana.Conclusion]The production method of decreasing the night heating temperature was not suitable for all kinds of plug seedlings.Using the method should be determined according to the actual situation. |
