摘　　要：为研究有机无机肥料配施对睡莲的影响,以热带睡莲"黄金国"为试验材料,设置4个不同的有机和无机肥比例,探讨其对"黄金国"花朵生长的影响。结果表明,随着无机肥的比例增大,"黄金国"的花朵直径、茎秆直径、花朵鲜重明显增加。与75%有机肥+25%无机肥相比,25%有机肥+75%无机肥的花朵直径、茎秆直径、花朵鲜重分别增加了3.53 cm、0.15 cm、6.35 g,增幅分别为26.15%、22.06%、61.06%;100%无机肥的花朵直径、茎秆直径、花朵鲜重分别增加了3.16 cm、0.21 cm、14.00 g,增幅分别为23.41%、30.88%、134.62%。提高无机肥施用比例有利于"黄金国"花朵的生长,其中以100%无机肥处理效果最显著,可以在生产中推荐施用。To study the effect of organic and inorganic fertilizer on water lity,taking Nymphaea"Eldorado"as experimental material,setting up four different ratios of organic and inorganic fertilizers to explore the effects on the growth of Nymphaea"Eldorado"flower.Results showed that the flower diameter,stem diameter and flower fresh weight of Nymphaea"Eldorado,,increased significantly with the increase of the proportion of inorganic fertilizer.Compared with those in the treatment of 75%organic fertilizer+25%inorganic fertilizer,flower diameter,stem diameter and flower fresh weight in the treatment of 25%organic fertilizer+75%inorganic fertilizer increased by 3.53 cm,0.15 cm and 6.35 g respectively,with an increase of 26.15%,22.06%and 61.06%respectively;and flower diameter,stem diameter and flower fresh weight in the treatment of 100%inorganic fertilizer increased by 3.16 cm,0.21cm and 14.00g respectively,with an increase of 23.41%,30.88%and 134.62%respectively.With the increase of inorganic fertilizer,Nymphaea"Eldorado"flowers grew better,and 100%inorganic fertilizer was the most effective for the growth,which can be recommended in the production.
