| 摘要: |
| 为探讨丛植菌根真菌(AMF)在小麦生长促进及根腐病抑制方面的效果,选取当地土著优良菌种——摩西球囊霉(Glomus mosseae)作为试验材料进行小麦盆栽接种试验,对比分析了有无AMF侵染条件下,小麦的生长指标、抗逆性能以及发病指数．结果表明:摩西球囊霉可与宿主小麦形成良好互利共生体系,菌根侵染率达42.2％;小麦对菌剂摩西球囊霉具有较强的依赖性,且地下器官高于地上;AMF强化使小麦的株高、根系总表面积、地上及地下生物量分别提高了26.67％、20.33％、38.9％和82. 3％．AMF侵染植株抗逆能力显著提高,其发病率、发病指数分别降低38％、3.74,根腐病得到有效防治．小麦种植过程中,接种摩西球囊霉菌剂能够有效促进小麦的营养生长,并显著降低小麦根腐病发生的概率和病情． |

| Abstract: |
| To discuss the promotion coming from the arbuscular mycorrhizal fungi (AMF) to the wheat and the inhibitory effect of the Fusariumsolani, we selected the excellent local native species—Glomus mosseae, as the materials for the wheat potted experiment, contrasted and analyzed the infection condition, the growth of index, the resistance, and the disease index of the wheat in the case of AMF. The result indicated that the application of the Glomus mosseae would increase the infection rate of the wheat, which could reach 42.2％. The wheat got a strong dependency for Glomus mosseae, and the underground is higher than that in the air; AMF could increase 26.67％, 38.9％ 82.3％,20.33％ for the height, the total area of the root, the aboveground biomass and the underground biomass respectively. AMF could prevent the wheat from Fusariumsolani, visually optimize the stressresistance of the plant, besides, the disease incidence and the disease index decreased 38％ and 3.74 respectively. In the process of wheat, the addition of AMF could effectively promote the growth of the wheat and inhibit the Fusariumsolani. |
