The performance of two bio-inoculants either in single or in combined applications with organic fertilizer was tested to determine their effect on plant growth and yield under normal and unfavorable field conditions such as low pH value and low content of P. Arbuscular Mycorrhiza Fungi (AMF; three species of ) and the plant-growth-promoting bacterial strain were applied to barley in a two-year field experiment with different soil pH levels and available nutrients. Grain yield; contents of P, N, K, and Mg; and soil microbial parameters were measured. Grain yield and the content of nutrients were significantly increased by the applications of mineral fertilizer, organic fertilizer, AMF, and , and the combined application of organic fertilizer with AMF and with over the control under normal growth conditions. Under low-pH and low-P conditions, only the combined application of the organic fertilizer with and organic fertilizer with AMF could increase the grain yield and content of nutrients of barley over the control.
对两种生物接种剂单独施用或与有机肥料混合施用的效果进行了测试，以确定它们在正常和不利田间条件（如低pH值和低磷含量）下对植物生长和产量的影响。在一项为期两年的田间试验中，将丛枝菌根真菌（AMF；三种）和促植物生长细菌菌株施用于不同土壤pH水平和有效养分的大麦。测量了谷物产量、磷、氮、钾和镁的含量以及土壤微生物参数。在正常生长条件下，施用矿物肥料、有机肥料、AMF和该细菌菌株，以及有机肥料与AMF和该细菌菌株的混合施用，与对照相比，显著提高了谷物产量和养分含量。在低pH和低磷条件下，只有有机肥料与该细菌菌株的混合施用以及有机肥料与AMF的混合施用能够比对照提高大麦的谷物产量和养分含量。
