本研究考察了五种细菌分离株（U、8M、36、102 和 111）对绿豆生长的影响。细菌分离物单独施用，或与磷酸锌[Zn-3(PO4)(2)中心点4H(2)O]一起施用。当幼苗接种分离株 102 时，所有植物生长参数均出现最大增加。与对照相比，具有 1 mM 磷酸锌的分离株 36 显示出幼苗长度的最大增加（35.1 厘米）。分离株 111 是最好的磷酸盐增溶剂，与 1 mM 盐结合使用时，在土壤中释放 13.29 ppm 磷 (P)，而分离株 36 显示出最大的磷吸收量，仅在土壤中留下 4.63 ppm。
This study examined the effects of five bacterial isolates (U, 8M, 36, 102, and 111) on the growth of Vigna radiata. Bacterial isolates were applied alone, or together with zinc phosphate [Zn-3(PO4)(2)center dot 4H(2)O]. The maximum increase in all plant growth parameters was seen when seedlings were inoculated with isolate 102. Isolate 36 with 1 mM zinc phosphate showed the maximum increase in seedling length (35.1 cm) as compared to controls. Isolate 111 was the best phosphate solubilizer, releasing 13.29 ppm phosphorous (P) in soil when used in combination with 1 mM salt, whereas isolate 36 showed maximum uptake of P, leaving only 4.63 ppm in soil.
