| 摘 要： | 通过根系分隔的盆栽试验，研究了地下部分隔对小麦//蚕豆间作系统中蚕豆的养分吸收和斑潜蝇发生的影响。结果表明：根系完全分隔处理蚕豆的生物量和N、P、K吸收量均高于其余2种分隔方式，在各个生育期，根系完全分隔处理与不分隔处理间差异均显著。根系分隔方式还影响了蚕豆斑潜蝇的发生，蚕豆斑潜蝇的发生均表现为根系不分隔（I）＜尼龙网分隔（M）＜完全分隔（P）。说明根系的相互作用，对蚕豆斑潜蝇的发生有一定的减轻作用。

| Abstract: | A pot experiment was conducted to study effects of root separation on fababean growth,nutrients uptake and occurrence of leafminer in wheat and fababean intercropping.The results showed that fababean shoot biomass and the amounts of N,P,K uptake were higher without root separation(I) than those with both mesh separation(M) and solid separation(P).In different growth stages,there were notable discrepancy levels between P and I at P<0.05.Root separation still affected occurrence of leafminer of wheat,and its occurance rate order.was I
