摘  要：
开展海南珍贵乡土树种坡垒、降香黄檀、秋枫套种南瓜、香蕉等农作物对林木保存率、生长情况及农作物产量影响的研究。结果表明:套种农作物可以显著提高坡垒、降香黄檀及秋枫的造林保存率,套种农作物3a后,3个树种的保存率均大于90%;而对照(没有套种农作物)的坡垒保存率仅为23%;套种农作物2a,坡垒、降香黄檀、秋枫的树高、胸径生长均与对照差异显著(p<0.05),其中以秋枫的生长最快,树高达3.83m、胸径达4.56cm,比对照分别提高了166.52%、228%

摘  要：
In this study,crops pumpkin(Cucurbita moschata) and banana(Musa nana) were interplanted in plantations of precious local tree species originated from Hainan island,including Hopea hainanensis,Dalbergia odorifera and Bischofia jacanica Bl aim to study the effects of interplanting crops on survival rate,growth of plantations and yield of crops.The results were summarized as follows:Interplanting crops can significantly increase survival rate of Hopea hainanensis,Dalbergia odorifera and Bischofia jacanica.After interplanting with crops for 3 years,the survival rate of the three tree species all exceeded 90%.By contrast,the survival rate of Hopea hainanensis as control without interplanting only reached 23%.After interplanting with crops for 2 years,Hopea hainanensis,Dalbergia odorifera and Bischofia jacanica presented significant differences with control at height and diameter at breast height(DBH) growth(p<0.05).Thereinto,Bischofia jacanica obtained fastest growth rate(3.83 m at height,4.56 cm at DBH),increased by 166.5%and 228.0%respectively compared with control.
