摘  要:目的:探讨滁菊人工栽培适宜的水氮管理模式。方法:采用二因素二次回归旋转组合设计,盆栽试验方式。结果:水氮耦合对滁菊花个数、产量、地上部分生物量有极显著影响,水氮间存在显著正相交互作用。水分对滁菊第一水花的产量、地上部生物量影响大于氮肥用量,而氮肥对菊花总产量的影响大于水分。结论:从鲜花产量角度考虑,盆栽滁菊水氮管理以田间持水量93%、氮肥用量(N)0.34 g/kg时较为适宜;从干花产量角度考虑,盆栽滁菊水氮管理以田间持水量75%、氮肥用量(N)0.2 g/kg时较为适宜。Objective : To discuss the suitable water and nitrogen management mode in artificial cultivation of Chuzhou Chrysanthemum morifolium. Methods : According to two factors quadratic regression rotation design experience, pot experiment was conducted. Results : There were remarkable effects of water and nitrogen coupling on inflorescence number, yield and overground part biomass of Chuzhou Chrysanthemum morifolium, and there were significant positive interaction between water and nitrogen. Effects of water on early-term inflorescence yield and overground part biomass of Chuzhou Chrysanthemum morifolium were higher than that of nitrogen fertilizer, but the effect on total inflorescence yield was opposite. Conclusion: Considering for the fresh inflorescence yield, the suitable water and nitrogen management mode is to keep 93% of the water holding capacity and nitrogen fertilizer (N)0. 34 g/kg of Chuzhou Chrysanthemum morifolium in pot experiment, and as for the dry inflorescence yield, the suitable water and nitrogen management mode is to keep 75% of the water holding capacity and nitrogen fertilizer (N)0. 2 g/kg.
