研究了土壤有效磷含量对两种丛枝菌根真菌侵染及菜豆生长的影响。研究了土壤有效磷（Bray No.2）浓度为2.5 mg/100 g ~（-1）时，AM真菌的侵染受到抑制。当土壤有效磷浓度为4.1 mg/100 g-1时，菜豆生长受到抑制。多济和塞利纳接种丛枝菌根真菌没有任何影响。在土壤有效磷水平为1.0 mg/100 g-1时，接种丛枝菌根真菌能增加菜豆的粒重，并随孢子数的增加而进一步增加。接种物中，球囊霉属（Glomus sp.）(y)感染率高于Gigaspora margarita。另外，菜豆的生长量也随感染率的增加而增加，表明球囊霉在菜豆中的侵染率较高。(y)是一种较适宜菜豆栽培的接种剂。
The effects of available phosphorus (P) content of Andosol on the infection of two species of arbuscular mycorrhizal fungi and the growth of kidney bean (Rhaseolus vulgaris L.) were studied. The infection of arbuscular mycorrhizal fungi was suppressed when soil-available P (Bray No.2) at planting time was 2.5 mg 100g-1. At 4.1 mg 100 g-1 soil-available P, the growth of kidney bean cv. Dozyo and Celina was in no way affected by the inoculation of arbuscular mycorrhizal fungi. At a soil-available P level of 1.0 mg 100 g-1, the inoculation of arbuscular mycorrhizal fungi increased the grain weight of kidney bean, and further increased with increasing spore number. Among inoculants, Glomus sp.(y) had a higher infection rate than Gigaspora margarita. Moreover, the growth of kidney bean was also higher with a higher infection rate, indicating that Glomus sp.(y) is a more suitable inoculant for kidney bean cultivation.
