[目的]研究施用缓释肥料对康乃馨产量、经济效益养分利用率和环境污染的影响.[方法]以康乃馨(Dianthus caryophyllus)为研究对象,采用田间小区试验探讨了缓释肥料在康乃馨上的施用效果与环保效应.[结果]施用缓释肥料可改善康乃馨主要的农艺性状;与Conv-F相比,缓释肥处理增加康乃馨产量达8.67%～20.83%,经济效益增加10.55万元/hm2,产投比提高达74.29%;在等NPK比例和等养分量条件下,缓释肥处理增加康乃馨产量达2.11%,经济效益增加1.48万元/hm2,产投比提高达16.2%;施用缓释肥料有效提高了康乃馨当季养分利用率,其中Opt-F-0.7%的氮、磷和钾当季养分利用率较Conv-F处理分别提高了13.88、8.57和30.14个百分点.[结论]缓释肥不但显著减少肥料资源的浪费,提高肥料利用率,而且减少了肥料养分流失造成的污染,对保护生态环境的保护和促进农业的可持续发展具有重要的现实意义.

[Objective]The aim was to study the effects of slow release fertilizer on the yield, economic benefit and nutrient use efficiency of carnation and environmental pollution.[Method]Taking carnation(Dianthus caryophyllus)as research object, the application effect and environ-mental protection effect of slow release fertilizer on carnation were discussed through field plot test.[Result]The main agronomic characters of carnation improved after the application of slow release fertilizer;compared with Conv-F treatment, the yield of carnation with slow release fertilizer increased by 18.67%-20.83%, and its economic benefit increased by 105 500 yuan/m2, while the radio of output to input improved by 74.29%;under the same NPK ratio and nutrient amount, the yield, economic benefit and ratio of output to input of carnation after the application of slow release fertilizer increased by 2.11%, 14800 yuan and 16.2%, respectively;besides, the application of slow release fertilizer improved the nutrient use efficiency of carnation, and N, P and K nutrient use efficiency in Opt-F-0.7%treatment increased by 13.88%, 8.57%and30.14%compared with Conv-F treatment.[Conclusion]Slow release fertilizer could not only reduce the waste of fertilizer resources and improve fertilizer use efficiency but also decrease the pollution caused by nutrient loss, Which had important practical significance for protecting ecological environment and promoting the sustainable development of agriculture.
