【摘要】 盆栽试验研究不同根系分隔方式蚕豆/玉米间作接种AM真菌和根瘤菌对其吸收有机磷影响结果表明,接种AM真菌均显著促进玉米和蚕豆吸收有机磷,与对照相比吸P量分别增加138.1%和82.3%;接种AM真菌和根瘤菌对蚕豆吸收有机磷有协同促进作用,蚕豆根瘤数、根瘤重和菌根侵染率显著增加,并改善与其间作玉米的营养状况,明显促进玉米生长。更多还原

【Abstract】 Pot experiments with different root separations were conducted to study the effect of inoculation of arbuscular mycorrhizal(AM) fungi and Rhizobium on the organic P uptake in faba bean[KG-*2]/maize intercropping system.The results show that P uptakes by faba bean and maize inoculated with AM fungi are increased by 138.1% and 82.3% compared with the control.Symmetrical effect on organic P uptake is observed when faba bean is inoculated with AM fungi and Rhizobium. The number of nodules,weight of nodules and mycorrhizal colonization of faba bean are significantly increased.At the same time the growth of the associated maize is significantly facilitated due to the improvement of nutrition condition.更多还原
