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.
