摘要:为了解功能菌单菌株与复合菌在蔬菜种植中的应用效果和差别,通过单菌株、复合菌与不施用菌株在黄瓜种植中的应用对比试验,观察黄瓜生长的抗病和增产效果。结果表明,与对照相比,各单菌株和复合菌对黄瓜成苗率、防病和增产效果方面均具有显著的促进作用,其中又以复合菌最佳,防病效果达60.20%,增产幅度达15.6%。由此可知,功能菌单菌株和复合菌在蔬菜中种植中均具有一定的菌肥功能,且以复合菌为佳。

Abstract: In order to understand application effects and the difference of single strain and compound bacteria in the planting of vegetables, the contrast test of application of single strain, compound bacterium and not applying strain(CK) on cucumber planting was carried out, and the effects of disease resistance and yield increase of cucumber was observed. The results showed that every single strain and compound bacterium all had promote role in cucumber seedling rate prevention and increase yield than not applying strain, and differences were significant. The compound bacterium was best, with prevention effect of 60.20%, and the increase rate of 15.6% compared with control. Therefore, single strain and compound bacterium had all certain function of bacterial manure in vegetable planting, and the compound bacterium was better.

微生物肥料又稱生物肥料、菌肥、接种剂,是指由单一或多个特定功能菌株通过发酵工艺生产的能为植物提供有效养分或防治植物病害的微生物接种剂。它不是以直接供给植物养分或农药为目的,而是通过特定菌株在土壤中的大量繁殖为植物提供养分或抑制有害菌的生产[1-5]。微生物肥料在农作物尤其是在蔬菜上的应用研究比较多[6-8],包括瓜果类[9-16]和叶菜类[17-19],应用效果主要是提高产量、品质和抗病[20]。但是,在已有文献报道中多为复合微生物肥料的应用研究,鲜有单菌株与复合菌在蔬菜应用效果的对比试验。本研究进行了单菌株与复合菌在黄瓜种植中应用效果的对比试验,以期了解复合菌与单菌株对蔬菜种植影响效果的差别。
