摘　　要：以千日红种苗为试材,根据花卉不同时期对氮、磷、钾的比率及需求量的不同,研究比较了以使用国产复合肥为主的6种施肥模式,对千日红生长的影响。结果表明:国产复合肥的施用效果与进口挪威复合肥相比差异不大,综合比较千日红开花株的外观、植株干鲜重、氮磷钾总含量等指标,用国产复合肥溶于水进行浇灌,其中苗期使用600倍液,旺盛生长期400倍液,现蕾期250倍液,开花期400倍液的效果最好。国产复合肥可取代进口复合肥用于千日红盆花的施肥,而且成本更低。Taking Gomphrena globosa L.as material,the effect of six fertilization patterns on the growth of Gomphrena globosa L.were studied according to the requirement of fertilizer at different stages.The results showed that the effect of domestic 15-15-15compound fertilizer and Normay compound fertilizer had no significant differences on the growth of blossom strains of Gomphrena globosa L.Comparison of appearance,plant fresh and dry weight,total content of N,P,K and other indicators of blossom strains,domestic compound fertilizer was dissolved in water to irrigate,the seedling use 600×liquid,vigorous growth period 400×fluid,bud period 250×liquid,blossom period 400×liquid was the best fertilization pattern.It indicated that the Norway compound fertilizer could be substitued by domsetic compound fertilizer in Gomphrena globosa L.
