The invention relates to the technical field of plant nutrient solution, in particular to an algae-bacteria composite nutrient solution and a preparation method and application thereof. An algae-bacteria compound nutrient solution is prepared from raw materials including the following parts by mass: 800-1200 parts of a Chlamydomonas debacillus solution, 10-50 parts of a Bacillus compound solution, 10-50 parts of a Pseudomonas solution, and a photosynthetic solution. Bacterial liquid 10 to 50 copies. The invention can not only significantly improve the yield, quality and resistance of crops, especially the growth potential of pepper and tomato seeds and the growth-promoting effect of seedlings, but also reduce the use of chemical fertilizers and pesticides, killing two birds with one stone. |
