Abstract:

种间根系或根际的相互作用对玉米/蚕豆和玉米/小麦间作体系中磷的吸收以及间作体系生产力有重要的影响.通过调控玉米根系的生长是否能影响间作体系的养分吸收和作物生长以及间作系统的生产力尚不清楚.本研究选用2个遗传背景相近的玉米根系近等基因型(大根的T149和小根的T222),在不同供磷条件下,分别与蚕豆和小麦进行间作.结果发现,大根系的T149显著增强了玉米/蚕豆和玉米/小麦间作体系中玉米对磷的竞争能力.在高磷条件下,T149可以增加玉米/蚕豆间作体系的生产力.在玉米/小麦体系中,2个磷水平下小麦均显著抑制玉米生长和磷的吸收.与T222相比,T149显著减轻了这种抑制作用.在低磷条件下,小麦/T149间作的总生物量显著高于小麦/T222.这些结果表明,玉米根系的遗传改良能够显著增强玉米/蚕豆以及玉米/小麦间作体系中玉米的生长和对磷资源的竞争能力,而间作体系生产力是否提高依赖于土壤磷有效性的高低.
