摘要:
以福建金线莲组培苗为试材,研究不同肥料处理对金线莲的生长状态、生长量和干物质含量的影响。结果表明:组培苗定植1个月后,开始喷施花多多1号肥1 000倍液,春秋季每10d喷施1次,夏冬季每月喷施1次,植株生长良好、不易感病,生长指标综合表现最好,12个月栽培期植株的成活率为86.0%、鲜重增长率为138.1%、干重为279mg、折干率为11.2%;适宜的肥料处理有利于改善金线莲生长状态,提高生长量和干物质含量,提升品质。
Abstract:
Effect of fertilizations on the growth,yield and dry matter content of Anoectochilus roxburghii plantlets was investigated.Among various fertilization treatments,the over-all growth performance of the plantlets was best by using Peters Professional No.1in 0.1% water dilution one month after planting followed by fertilizing once every 10 days in spring and autumn,then,once a month in summer and winter.During the 12-month cultivation time period,the plantlets were not infected by any diseases,and showed the following results on the growth indices:(a)a survival rate of 86.0%,(b)a fresh weight increase of 138.1%,(c)a dry weight of 279 mg per plant,and(d)a DW/FW ratio at 11.2%.Consequently,it appeared that the selected fertilization could be recommended for the cultivation of A.roxburghii.
