摘要
以泰国无筋地豆为试材,在温室盆栽的条件下,分别单接种丛枝菌根真菌(AM)、单接种根瘤菌(RH)、双接种丛枝菌根真菌和根瘤菌(AM+RH),以不接种为对照(CK),研究不同接种方式对菜豆植株生长、结瘤、单株总荚质量、AM菌根侵染率、植株氮磷含量及吸收量、单株黄叶率等的影响。结果表明:双接种AM+RH能显著促进菜豆植株的生长,植株总干质量比单接种AM、单接种RH和CK分别增加34.3%、82.3%和57.9%;双接种AM+RH可提高菜豆单株总荚质量,促进菜豆植株对氮、磷元素的吸收,全株吸磷量比单接AM、单接RH和CK分别增加42.1%、314.8%和325.4%,全株吸氮量比单接种AM、单接种RH和CK分别增加36.8%、45.1%和43.4%;AM真菌与RH具有协同促进的作用,且AM真菌能有效提高菜豆的抗性,减少叶片变黄的比率,减轻了病害为害程度。
Under greenhouse condition, common bean （Phaseolus vulgaris Linn. ） ＇Taiguowujindidou＇ was sowed in pots to estimate the effects of different inoculation ways on bean＇ s plant growth, nodulation, total pod weight of single plant, AM colonization rate, nitrogen and phosphorus contents and absorption of bean plant. When seeding, the beans were inoculated with Glomus mosseae （ AM ）, rhizobia （ RH ）, Glomus mosseae and rhizobia （ AM＋RH ）, and the beans without inoculation were taken as the control （ CK ） . The results indicated that dual inoculation （ AM＋RH ） could obviously promote the plant growth of beans. Compared with inoculation with Glomus mosseae （ AM ）, rhizobia （ RH ） and none （ CK ）, the plant total dry weight of the beans inoculated with AM＋RH increased 34.3%, 82.3% and 57.9%, respectively. Besides, the dual inoculation could increase the total pod weight of single plant and promote bean＇ s absorption of nitrogen and phosphorus. The phosphorus absorption of total plant was increased by 42.1%, 314.8% and 325.4%, respectively than that by AM, RH and CK. While, the nitrogen absorption of total plant was increased by 36.8%, 45.1% and 43.4%, respectively than that by AM, RH and CK. The Glomus mosseae and rhizobia had synergistic effect on common bean, and the Glomus mosseae could effectively improve bean＇ s resistance, reduce the yellow leaf ratio, and thus decrease the occurrence of diseases.
