Low-temperature-resistant low-illumination fertilizer as well as preparation method and application thereof

The invention discloses a low-temperature-resistant low-illumination fertilizer as well as a preparation method and application thereof, and the low-temperature-resistant low-illumination fertilizer comprises the following components in parts by weight: 65-80 parts of a trash fish extracting solution, 6-8 parts of vegetable protein, 0.03-0.05 part of compound enzyme, 2.5-4.5 parts of nutrient elements and 4-10 parts of an auxiliary agent. The invention belongs to the technical field of agricultural fertilizers, and utilizes various natural plant growth regulating substances such as polypeptide and oligopeptide contained in fish hydrolyzed protein and vegetable protein to effectively regulate plant growth, enhance absorption and utilization of nutrient elements by plants under low-temperature and low-illumination conditions, help the plants to reduce adverse effects caused by low temperature and low illumination, and improve the yield of the plants. The low-temperature-resistant low-illumination fertilizer can
