    摘要:

    选取对番茄青枯菌有明显抑制作用的产脂肽菌株XZ-173,与有机肥混合发酵制成生物有机肥。通过温室盆栽试验,评价了该生物有机肥对番茄青枯病的防治效果及对番茄的促生效用。结果表明,生物有机肥能够显著降低青枯病发病率,相对防效达56.8%。与施用化肥和未添加XZ-173的有机肥处理相比,施用该生物有机肥能显著提高番茄植株叶绿素含量、番茄地上部和地下部生物量、根际土壤细菌和放线菌数量,显著降低根际土壤中真菌数量。生物有机肥的有益效果使其在作物种植中具有广阔的应用前景。

    Abstract:

    A greenhouse pot experiment was carried out to study effects of a kind of bioorganic fertilizer (BOF) prepared out of fermentation of organic manure using as a starter strain XZ-173 lipopeptide-producing bacteria that are obviously effective in inhibiting the pathogen causing tomato bacterial wilt (TBW). Results show that the BOF effectively reduced the incidence of TBW with a relative control efficiency being 56.8%. Compared with treatments using chemical fertilizers or organic manure without using XZ-173 as starter, Treatment BOF significantly increased chlorophyll content of tomato leaves, biomasses of roots and shoots, and counts of bacteria and actinomycetes in rhizosphere soil, but reduced population of rhizospheric fungi. These beneficial effects of the BOF give it a broad prospect for application in cropping.
