摘　　要：为了寻求人工调控存在化感物质间作群体的理论依据,通过盆栽试验,探讨不同供水水平下(田间持水量的75%、60%和45%),小麦根系分泌物丁香酚对单作和间作蚕豆、小麦生长速率(Crop Growth Rate,CGR)及籽粒产量的影响。结果表明:在蚕豆苗期-始花期、结荚-成熟期2个生育阶段,丁香酚对蚕豆生长速率整体表现为抑制作用,但结荚-成熟期75%供水水平下的单作、60%供水水平下的间作除外,增加供水缓解了单作蚕豆的抑制作用、加剧了间作蚕豆的抑制作用,间作模式可缓解抑制;自苗期以后,丁香酚对小麦生长速率表现为抑制作用,且增加供水亦不能缓解抑制,但在开花-成熟期间作模式可以缓解抑制。在同等供水水平下,间作籽粒产量与单作籽粒产量的加权平均相比增加了24.92%-52.74%。丁香酚除对45%供水水平下小麦籽粒产量有化感促进作用以外,对两种作物的其他处理均呈现化感抑制作用。间作可弱化丁香酚对小麦、蚕豆籽粒产量的化感作用。In order to provide theoretical basis for the manual control regulation of intercropping system that existed allelochemicals, pot experiment was carried out to research the effect of eugenol on crop growth rate and grain yield of wheat fabafloean intercropping system at water application of 75%, 60% and 45% field capacity. The results showed that eugenol could inhibite the crop growth rate （CGR）of fava bean in the seedling-beginning flower and pod setting-mature period of faba bean, except sole faba bean with 75% water supply level and the intercropped faba bean with 60% water supply level, increased water supply can alleviate the inhitory action of eugenol on the sole faba bean, but the inhitory action of eugenol on the intercropped fava bean exacerbate, intereropping planting pattern can alleviate the inhitory action; eugenol could inhibite the wheat CGR after seedling period, increasing water supply can not alleviate the inhitory action of eugenol, intercropping planting pattern can alleviate the inhitory action of eugenol on the wheat CGR at the stage of flowering to maturity. Compared to weighted average sole grain yield, intercropped grain yield was increased by 24.92%-52.74% under the same water supply. Other treatments showed that allelopathy has inhibitory effect on the grain yield of two crops except 45%water supply level. Intercropping planting pattern can alleviate the allelopathy of eugeno on the wheat, fava bean grain yield.
