摘　　要：采用二因素二次回归旋转组合设计,以盆栽试验方式研究了水、氮因子对滁菊产量和品质的影响,探讨了滁菊人工栽培适宜的水氮管理模式。研究结果表明,水氮耦合对滁菊花产量、叶片水提总黄酮和氯原酸含量、滁菊花水提总黄酮和氯原酸含量均有极显著影响,水氮间存在显著交互作用。氮肥因子对滁菊花产量、总黄酮含量、氯原酸含量的影响大于水分因子。当土壤水分水平为0.284 1,氮肥水平为0.403 7时,即田间持水量80%,氮肥用量0.257g/kg时,滁菊花产量最高,达18.09g/株;当土壤水分和氮肥用量均为-1.414水平时,即田间持水量50%,氮肥用量为0g/kg时,滁菊花总黄酮含量和氯原酸含量最大。从滁菊花产量、品质角度综合考虑,滁菊生育前期水氮管理以中水中氮较为适宜,滁菊现蕾开花期以低水低氮较为适宜。According to two-factor quadratic regression rotation design,effects of water and nitrogen fertilizer coupling on yield and quality of Chuzhou Chrysanthemum morifolium were studied by apot experiment and the suitable water and nitrogen management modes were investigated.Results showed that remarkable effects of water and nitrogen coupling on flower yield,total flavonoid content of leaf or flower,chlorogenic acid content of leaf or flower of Chuzhou Chrysanthemum morifolium were displayed,and there was a significant interaction between water and nitrogen.Effects of water on flower yield,total flavonoid content and chlorogenic acid content were more significant than those of nitrogen fertilizer.When soil water and nitrogen fertilizer were at 0.284 1and 0.403 7levels,respectively,namely,keeping 80% of the field water capacity and 0.257g/kg nitrogen fertilizer,flower yield of Chuzhou Chrysanthemum morifolium reached a maximum up to 18.09 g/plant;and when both of soil water and nitrogen fertilizer were at-1.414level,namely,keeping 50%of field water capacity and 0g/kg nitrogen fertilizer,total flavonoid content and chlorogenic acid content of Chuzhou Chrysanthemum morifolium flower were maximal.Considered from the field of flower yield and quality,a suitable management mode of water and nitrogen is to keep middle level in the beginning stages of growth of Chuzhou Chrysanthemum morifoliumand low level in the squaring stage and flowering period.
