Microalgae biological synergist as well as preparation method and application thereof

The invention discloses a microalgae biological synergist as well as a preparation method and application thereof, and belongs to the technical field of microbial fertilizers. The microbial synergist contains bacillus subtilis, bacillus licheniformis, arthrobacter citratus, enterococcus faecium, a chlorella sorojin extracting solution and the like, and experimental results show that the microbial synergist containing the microalgae can promote root growth of plants such as wheat, corn, cotton and the like; the disease conditions of root rot and root-knot nematode are effectively reduced, and compared with a conventional fertilizer, the yield increasing effect of crops is more remarkable. 本发明公开了一种微藻生物增效剂及其制备方法和应用，属于微生物肥料技术领域。该微生物增效剂含有枯草芽孢杆菌、地衣芽孢杆菌、柠檬节杆菌、屎肠球杆菌、索罗金小球藻提取液等，实验结果表明，本发明提供的含有微藻素的微生物增效剂能够促进小麦、玉米、棉花等植株的根系生长，有效降低根腐病和根结线虫的病害情况，与仅使用常规肥料相比，作物增产效果更加显著。
