The invention provides a cold-resistant microbial liquid fertilizer which comprises, by weight, 0.5-1.5 parts of alginic acid, 1-2 parts of low-temperature-resistant microbial agent, 12-25 parts of a macroelement fertilizer and 30-40 parts of an organic waste liquid. Also provides a preparation method of the cold-resistant microbial liquid fertilizer. Compared with the traditional liquid fertilizer, the cold-resistant microbial liquid fertilizer can effectively improve the cold resistance of crops, improve the ecological environment of the rhizosphere of the crops and promote the growth of the crops. |
