Microbial composition and complex microbial inoculant for improving quality and increasing yield of crops and application of microbial composition and complex microbial inoculant

The invention relates to the technical field of microorganisms, in particular to a microbial composition for improving quality and increasing yield of crops, a complex microbial inoculant and application of the microbial composition and the complex microbial inoculant. The microbial composition is prepared from the following raw materials in parts by viable count: 40 to 70 parts of rhodopseudomonas palustris, 20 to 40 parts of rhodopseudomonas sphaeroides and 5 to 20 parts of rhodospirillum rubrum. The product has disease-resistant, anti-freezing and quality-improving effects, can significantly promote photosynthesis of plants, especially green onion, ginger and garlic, and has a significant yield-increasing effect. 本发明涉及微生物技术领域，具体而言，涉及一种用于作物提质增产的微生物组合物、复合菌剂及其应用。该微生物组合物，按活菌数计，包含40～70份的沼泽红假单胞菌、20～40份的球形红假单胞菌以及5～20份的深红红螺菌。本产品具有抗病、抗冻、提质的效果，能显著促进植物，特别是葱、姜、蒜的光合作用，增产效应显著。
