摘要
为分析植物根际促生细菌(Plant growth-promoting rhizobacteria,PGPR)在烤烟提质增产中的作用,从攀枝花烟区优质烟株根际土壤中分离筛选出促生性好且相互之间不存在拮抗作用的产吲哚乙酸菌、溶磷菌和解钾菌,这3种细菌的混合物即为多功能PGPR混合菌剂。采用盆栽试验和大田试验,研究了多功能PGPR混合菌剂对烤烟提质增产的作用。结果表明:多功能PGPR混合菌剂可改善烤烟的农艺性状及烟叶的化学品质,降低烤烟发病率。以复合肥为底肥施加PGPR混合菌剂可使中上等烟叶比例提高22.0%;以复合肥和有机肥为底肥,施加PGPR混合菌剂可使中上等烟叶比例和产值分别提高34.5%和26.4%。
To analyze the effects of plant growth-promoting rhizobacteria（PGPR） on the quality improvement and yield increase in flue-cured tobacco, three bacterium strains, indole-3-acetic acid（IAA） producing bacteria,phosphate solubilizing bacteria and potassium solubilizing bacteria, which possessed better promoting and non-antagonism activities were isolated from tobacco rhizosphere soil in Panzhihua.The three strains were mixed to prepare multi-function PGPR microbial inoculant, pot and field experiments were carried out to study the effects of multi-function PGPR microbial inoculant on the quality improvement and yield increase in flue-cured tobacco.The results showed that the multi-function PGPR microbial inoculant improved agronomic traits of flue-cured tobacco and chemical quality of tobacco leaves, and decreased the incidence of tobacco diseases.In the treatment of compound fertilizer as base fertilizer combined with multi-function PGPR microbial inoculant, the middle and high grade proportion of tobacco leaves significantly increased by 22.0%.In the treatment of compound fertilizer and organic fertilizer as base fertilizer combined with multi-function PGPR microbial inoculant, the middle and high grade proportion of tobacco leaves and output value significantly increased by 34.5% and 26.4%, respectively.
