    摘要:

    向含解淀粉芽孢杆菌SQR9的生物有机肥中添加山梨醇研制了新型生物有机肥，并通过黄瓜盆栽和拟南芥培养试验研究了该新型生物有机肥的促生效应与机理。结果表明，含解淀粉芽孢杆菌SQR9的生物有机肥对黄瓜具有显著促生效果，添加山梨醇有利于促进解淀粉芽孢杆菌SQR9在土壤中定殖，能进一步提高生物有机肥的促生效应。施用该新型生物有机肥能显著提高土壤中速效养分的含量以及黄瓜对养分的吸收。山梨醇能有效促进菌株SQR9分泌生长素（吲哚乙酸，IAA），进而促进野生型拟南芥根系的生长，而在使用IAA不敏感突变体时促生效果消失，说明山梨醇促进有益菌SQR9分泌IAA是该新型生物有机肥显著促进作物生长的机理之一。本研究提出了新型生物有机肥研发的新思路，为植物促生菌新应用模式的开发提供了理论依据。

    Abstract:

    Objective In this study, a novel bio-organic fertilizer was designed by adding sorbitol, which is one of the preferred carbon sources for the functional strain Bacillus amyloliquefaciens SQR9, to the normal bio-organic fertilizer rich in strain SQR9(2×108 CFU·g–1). The plant growth promotion effect was evaluated. The mechanism for elevation of plant growth promotion effect of the normal bio-organic fertilizer by sorbitol addition was studied.Method The effect of this novel bio-organic fertilizer on cucumber growth, soil biological and chemical properties was evaluated by pot experiments. The effect of sorbitol on plant growth promotion and stimulating IAA (indole-3-acetic acid) production by strain SQR9-gfp was investigated by culturing experiment using Arabidopsis.Result The pot experiment showed that the application of this novel bio-organic fertilizer could promote cucumber growth by increasing the soil nutrient availability and the colonization of strain SQR9-gfp. The addition of sorbitol could promote IAA production by strain SQR9-gfp. Comparing to the wild type Arabidopsis, the plant growth promotion effect of sorbitol addition vanished on the IAA insensitive mutant Arabidopsis pin2.Conclusion These results suggest that the application of this novel bio-organic fertilizer can promote plant growth. The addition of sorbitol can promote IAA production by SQR9-gfp and this is one of the mechanisms through which the novel bio-organic fertilizer boosted plant growth.
