不同施肥模式对黄帝菊开花株生长的影响

Effect of Different Fertilization Patterns on Growth of Blossom Strains of Melampodium paludosum

目前许多生产者都使用N-P2O5-K2O=15-15-15的进口挪威复合肥对黄帝菊进行追肥。本试验设定使用了以国产复合肥为主的6种施肥模式,对黄帝菊进行了生长比较试验。综合开花株的外观指标来看,在植株现蕾期之前用国产15-15-15复合肥添加0.1%尿素配成500倍液浇灌及现蕾期之后直接将复合肥配成500倍浇灌这种模式,与使用进口挪威复合肥的差异不大。说明对黄帝菊盆花的施肥,国产复合肥完全可取代进口复合肥,而且成本更低。

At present,many producers are using Norway compound fertilizer with N-P2O5-K2O=15-15-15 in Huangdi chrysanthemum（Melampodium paludosum）.Six fertilizer contain mainly domestic compound fertilizer were used to study the effect of fertilizer on growth of Melampodium paludosum.The results showed that domestic 15-15-15 compound fertilizer with 0.1% urea as 500 solution befere budding and domestic 15-15-15 compound fertilizer without other fertilizer after budding had the same effect on the appearance characteristic as Norway compound fertilizer.It indicates that the Norway compound fertilizer can be substitued by domsetic compound fertilizer in Melampodium paludosum.
