摘　　要：以油桐为供试植物,通过油桐+红薯、油桐+黄豆和油桐+玉米不同套种模式研究其对油桐幼林枝和叶全氮、磷、钾影响。结果表明:不同套种模式处理间油桐枝叶全氮磷钾含量差异极显著,油桐+黄豆套种模式油桐幼林枝叶全氮磷钾含量相对较高,油桐+红薯套种模式全磷钾含量相对较高,油桐+玉米套种模式油桐枝叶全氮磷钾含量相对较低。To explore utilization of agroforestry patterns including Vernicia fordii ＋ Ipomoea batatas ,V .fordii ＋Gly-cine max ,Vernicia fordii ＋Zea mays ,we investigated effects of agroforestry patterns on the total contents of N,total P and total K of branch and leaf of V .fordii in the study.The results showed that it was very significant different of the total contents of N,P,and K of branch and leaf of V .fordii interplanting with I .batatas ,G .max ,and Z .mays .The total contents of N,P,K was higher in V .fordii interplanting with G .max ,and that of P and K was higher in V .fordii interpanting with I .batatas ,and that of N,P,and K was less in V .fordii interplanting with Z .mays .
