在2003年和2005年期间，测试了两种芽孢杆菌菌株OSU-142（固氮）和M3（固氮和解磷）单独或组合对有机种植的根蘖果树莓（cv.在土耳其埃尔祖鲁姆省，从产量、生长、叶片营养成分和土壤营养元素组成的变化方面对传统植物进行了研究。结果表明，芽孢杆菌M3处理促进了植株生长，并导致显著的产量增加。树莓根系和根际接种M3和/或OSU-142 + M3，与对照相比，产量分别增加33.9%和74.9%，茎长分别增加13.6%和15.0%，单茎丛数分别增加25.4%和28.7%，单茎浆果数分别增加25.1%和36.0%。有机栽培条件下，OSU-142 + M3处理的树莓叶片N、P、Ca含量以及M3和OSU-142 + M3处理的树莓叶片Fe、Mn含量均显著提高。施用细菌对土壤全N、有效P、K、Ca、Mg、Fe、Mn、Zn含量和pH值也有显著影响。土壤有效P含量由研究开始时的1.55 kg P_2O_5/d增加到2.83 kg P_2O_5/d。M3处理的P2 O 5/d为5.36 kg，OSU-142 + M3处理的P2 O 5/d为4.71 kg。本研究的结果表明，芽孢杆菌M3单独或与芽孢杆菌OSU-142组合具有在有机生长条件下增加树莓植物的产量、生长和营养的潜力。(c)2006 Elsevier B.

During 2003 and 2005, plant growth promoting effects of two Bacillus strains OSU-142 (N-2-fixing) and M3 (N-2-fixing and phosphate solubilizing) were tested alone or in combinations on organically grown primocane fruiting raspberry (cv. Heritage) plants in terms of yield, growth, nutrient composition of leaves and variation of soil nutrient element composition in the province of Erzurum, Turkey. The results showed that Bacillus M3 treatment stimulated plant growth and resulted in significant yield increase. Inoculation of raspberry plant roots and rhizosphere with M3 and/or OSU-142 + M3, significantly increased yield (33.9% and 74.9%), cane length (13.6% and 15.0%), number of cluster per cane (25.4% and 28.7%) and number of berries per cane (25.1% and 36.0%) compared with the control, respectively. In addition, N, P and Ca contents of raspberry leaves with OSU-142 + M3 treatment, and Fe and Mn contents of the leaves of raspberry with M3 and OSU-142 + M3 applications significantly improved under organic growing conditions. Bacterial applications also significantly effected soil total N, available P, K, Ca, Mg, Fe, Mn, Zn contents and pH. Available P contents in soil was determined to be increased from 1.55 kg P2O5/da at the beginning of the study to 2.83 kg P2O5/da by OSU-142, to 5.36 kg P2O5/da by M3 and to 4.71 kg P2O5/da by OSU-142 + M3 treatments. The results of this study suggest that Bacillus M3 alone or in combination with Bacillus OSU-142 have the potential to increase the yield, growth and nutrition of raspberry plant under organic growing conditions.
