The application discloses a microbial water-soluble
fertilizer and a preparation method thereof, and belongs to the technical field of bio-
organic fertilizer.The water-soluble
fertilizer comprises the following components:
nutrient elements, fish
hydrolyzed protein, low-temperature-resistant microorganisms,
plant growth regulating components, a surfactant and water.The water-soluble
fertilizer is added with
nitrogen,
phosphorus,
potassium and other macronutrient elements and
calcium,
magnesium,
zinc and other
micronutrient elements, so that sufficient
nutrient substances are provided for crops.The water-soluble fertilizer is added with
plant growth regulating components composed of 5-aminoacetyl propionic acid,
trehalose and amine ester, and the three components are used in combination, so that the adaptability of plants to a low-temperature environment can be effectively improved.Two low-temperature-resistant microorganisms, i.e., new cold-tolerant
branch actinomyces and Tianshan
branch actinomyces, are selected and added, and the two cold-tolerant fungi work together to improve the
stress resistance of crops.The water-soluble fertilizer is used in combination with spraying and flushing, so that the low-temperature growth of tomatoes is effectively promoted, the
stress resistance and quality of crops are improved, and the application prospect is wide.
