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 explore the suitable water and nitrogen management mode of artificial cultivation of chrysanthemum. Methods: Two-factor quadratic regression rotation combined design, pot test method. Results: Water and nitrogen coupling had a significant impact on the number of chrysanthemum, yield and aboveground biomass, and significant positive correlation existed between water and nitrogen. The effect of water on the yield of the first spray of Chu Ju and aboveground biomass was greater than that of nitrogen fertilizer, while the effect of nitrogen fertilizer on the total yield of chrysanthemum was greater than that of water. Conclusion: From the perspective of the yield of flowers, the nitrogen management of potted Juju water was more suitable when the water holding capacity was 93% and the nitrogen application rate (N) was 0.34 g / kg. Considering the dry flower production, , Nitrogen fertilizer (N) 0.2 g / kg is more appropriate.
