缓释肥料与速效肥料对鸡冠花盆栽肥效对比研究

Effects of Slow-release Fertilizer and Fast-release Fertilizer on Celosia cristata L.by Pot Experiment

采用盆栽试验的方法,研究了缓释花卉肥与速效花卉肥在平均苗高为10 cm的盆栽鸡冠花上的应用效果。结果表明:各施肥处理与对照CK相比,在株高、冠幅和生物量上均有明显提高;缓释肥料与速效肥料相比,缓释肥料更能促进鸡冠花根、花、生物量总重的增加以及花重比的提高。其中,花鲜重在肥料全量水平和2/3量水平上分别提高61.95%和71.57%,花重占其生物量总重的比例分别提高29.67%和76.51%;可以看出,在相同施氮量水平下,2/3量缓释肥处理(T2)优势最明显。施用专用缓释肥料对于提高鸡冠花的品质和观赏质量有明显作用和意义。

A pot experiment was used to study the effects of slow-release fertilizer and fast-release fertilizer on Celosia cristata L.with average height of 10 cm.The results showed that contrast with CK,the stem length,biomass and crown of cockscomb were improved obviously by fertilization treatments.Compared with fast-release fertilizer,the slow-release fertilizer enhanced Celosia cristata L.root growth,flower growth,total biomass and flower weight ratio,with the flowers fresh weight of full amount fertilizations and 2/3 amount fertilizer treatments were increased by 61.95%and 71.57%respectively,and the flower weight ratio increased by 29.67%and 76.51%respectively;we found that 2/3 amount of slow-release fertilization(T2) with pure N 0.37 g/pot was the best application rate.Finally we concluded that the application of slow-release fertilizer plays a significant role in improving the quality and ornamental value of Celosia cristata L..
