摘要
采用盆栽试验,研究了4株核桃根际促生菌(PGPR)X12、X65、X95、X128对核桃苗的促生作用。结果表明,各菌株均能促进核桃苗根系生长,提高根系活力及叶片光合特性,其中X95、X128菌株对核桃主要生长指标有明显的促进作用,而X128的促进作用最明显。综合分析,以X128在核桃微生物肥料的生产与研制中具有较大应用潜力。
The growth-promoting effects of 4 plant growth -promoting rhizobacteria （ PGPR） strains, X12, X65, X95 and X128, on walnut seedlings were studied by pot experiment .The results showed that the 4 PGPR strains all could promote root growth , increase root activity and leaf photosynthetic characteristics .A-mong which , X95 and X128 had obvious promoting effects on main growth indexes of walnut , and X128 had the most.In conclusion , X128 had great application potential in the production and development of microbial fertilizers of walnut .
