摘　　要：用7种配方肥料,在海南省西华农场上进行了为期1年的2年生橡胶树施肥试验。结果表明:不同施肥处理对胶树径围增长效应之间有极显著的差异。其中,处理6(施氧化镁0.4kg/株)、处理8(施尿素0.6kg/株、施过磷酸钙1.2kg/株、施氧化镁0.4kg/株、施干牛粪6kg/株)与对照相比,差异极显著,分别比对照增长25.5%、26.4%;其余处理与对照相比,差异不显著,其中,单施尿素(0.6kg/株)效果最差,单施氯化钾(0.4kg/株)效果较差。Experiments were conducted for one year to study the effect of fertilizer application on two-year-old Hevea brasiliensis at Xihua Farm of Hainan Province using seven formula fertilizers. The results indicated that the effects of different fertilizing treatments on girth growth of rubber trees were very significant. Compared with CK, Treatment 6 （0.4 kg MgCI） and Treatment 8 （0.6 kg urea＋1.2 kg superphosphate, 0.4 kg MgO, 6 kg dry cow dung） very significantly increased the girth growth, respectively by 25.5% and 26.4%; Other treatments did not increased the girth growth significantly, among these treatments, Treatment 3 had the least effect, followed by single application treatment of 0.4 kg KC1.
