不同套种模式对油桐枝和叶N、P、K含量影响

Effects of Different Interplanting Patterns on the Content of N，P，K of Branch and leaf of Vernicia fordii

摘要:

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。

Abstract:

Abstracts:To explore utilization of agroforestry patterns including Vernicia fordii+Ipomoea batatas,V.fordii+Glycine 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.
