　　针对冀西山区石灰性土壤施用磷肥后易形成难溶性磷的特点，以不施用菌肥为CK，以5种不同的解磷溶磷菌肥为研究对象，分析了施用不同菌肥对土壤速效磷含量、植株全磷含量、籽粒全磷含量和籽粒产量的影响。结果表明：施用不同菌肥对玉米苗期的土壤速效磷含量影响不大，对大喇叭口期的土壤速效磷含量影响变大但差异未达到显著水平；收获期所有施用菌肥的土壤速效磷含量均＞CK，其中处理Ⅳ与CK差异达到了显著水平。本研究条件下，施用不同菌肥对植株和籽粒的全磷含量影响不显著。参试菌肥均能够提高玉米产量，除处理Ⅴ外，其他菌肥处理的产量均＞9000 kg/hm2，增产幅度（15.6％～24.2％）明显。

In the light of calcareous soil easily formed sparingly soluble phosphorus after applied phosphate fertilizer in west mountain regions of Hebei Province , taking 5 kinds of different phosphorus dissolving microbial fertilizer as research objects, without applying microbial fertilizer as control, the effects of different microbial fertilizers on soil available phosphorus content, plant total phosphorus content, grain total phosphorus content and grain yield of maize were analyzed.The results showed that applied different microbial fertilizers had little effect on soil available phosphorus content at seedling stage of maize , had a little effect on soil available phosphorus content at big flare stage of maize and was not obvious.The soil available phosphorus contents of all applied microbial fertilizers at mature stage were higher than CK, and there was significant difference between treatment Ⅳ and CK.In the experiments, the effects of total phosphorus contents of plant and grain were not significant after applied the microbial fertilizers.The the yields of maize applied 5 kinds of microbial fertilizer were increased , in addition to treatment V, the yields of others treatments were higher than 9 000 kg/hm2 and increased significantly (15.6%-24.2%) .
