摘　　要： 以控释复合肥CRF(N∶P2O5∶K2O=20∶8∶10)和普通复合肥CCF(N∶P2O5∶K2O=15∶15∶15)为材料,在大田条件下,研究等氮素用量控释复合肥和普通复合肥对杭白菊产量、品质和养分利用率的影响。结果表明:与普通复合肥相比,控释复合肥能够改善植株农艺性状,提高经济产量,增加水溶性浸出物、可溶性糖、蛋白质、总黄酮类化合物在花中的含量。由于控释复合肥与普通复合肥的养分配比不同,等氮素条件下,控释复合肥的肥料施用量比普通复合肥减少25%。从综合性状看,以施肥量为900 kg/hm2的CRF2处理最佳,节省肥料,提高经济效益,减少环境污染。 Field experiments were conducted to study the effect of controlled release compound fertilizers （CRF） on the yield and quality of Chrysanthemum morifolium Ramat. and nutrient use efficiency. The result showed that controlledrelease compound fertilizer treatments CRF improved the agronomic characteristics of C. morifolium Ramat. and in CRF increased economic yield. CRF1 Utilization of nitrogen,phosphorus and potassium increased 6.61% ,0.95 % and 16.72% than CCF1, CRF2 was higher than CCF2 7. 71 %, 2.00 % and 17.72 %, respectively. In addition, CRF also showed a beneficial result on the quality,i, e,improved the contents of Hydrophilic extract＇ soluble sugar, protein and total flavonoids in flower compared to CCF： Under,the same nitrogen conditlons,CRF amount of fertilizer： was 25 0% iess than CCF. Synthetically, the optimum fertilizer amount was CRF2,900 kg/hm^2 , improving economic efficiency, reducing environmental pollution.
