    摘要:

    根际促生细菌(PGPR)与普通育苗基质联合形成生物育苗基质，能够有效促进PGPR菌株的根际定殖，从而增强菌株促生效果的发挥。本研究以辣椒和番茄两种经济作物为供试材料，采用拌土的方式向基质中添加PGPR菌株LZ-8发酵液形成生物育苗基质，研究了该生物基质对这两种作物苗期的促生效果及种苗移栽后大田产量的增加情况。结果表明：含PGPR菌株的生物育苗基质对辣椒和番茄苗期均具有显著的促生效果，其中苗期辣椒和番茄的株高、茎粗、叶面积、鲜重和干重分别比对照高出22%、15.9%、33.6%、21.84%、31.25% 和26.8%、29.4%、62%、72.7%、83.3%；生物基质所育种苗移栽至大田后显著增加了辣椒和番茄的产量，分别比对照增产22% 和11%。

    Abstract:

    Combining plant growth promoting rhizobacteria (PGPR) with common seedling substrate to create biological matrix could enhance the root colonization ability of the strain and subsequently improve the promoting ability of the PGPR strain for plant growth. In this study, effects of novel biological matrix produced by PGPR strain Bacillus pumilus LZ-8 on the nursery growth and field yield of two economic crops, pepper and tomato, were investigated. Results showed that application of novel biological matrix significantly increased the plant height, stem diameter, leaf area, and the fresh and dry weights by 22%, 15.9%, 33.6%, 21.84% and 31.25%, respectively, for pepper, and by 226.8%, 29.4%, 62%, 72.7% and 83.3%, respectively, for tomato, compared to the control with common seedling substrate. After being transported to the field, the treatment with seedlings grown in the biological matrix showed significant increases in the yields of pepper and tomato by 23% and 11%, compared to the control with seedlings grown in the common seedling substrate.
