Microbial water-soluble fertilizer and preparation method thereof

Abstract

The invention discloses a microbial water-soluble fertilizer and a preparation method thereof, belonging to the technical field of biological organic fertilizers. The water-soluble fertilizer comprises nutrient elements, fish protein hydrolysate, low-temperature resistant microorganisms, plant growth regulating components, a surfactant and water. The invention adds a large amount of nutrient elements such as nitrogen, phosphorus, potassium and the like and medium trace elements such as calcium, magnesium, zinc and the like, thereby providing sufficient nutrient substances for crops. According to the invention, the plant growth regulating components consisting of 5-aminolevulinic acid, trehalose and diethyl aminoethyl hexanoate are added, and the three components are used together, so that the adaptability of plants to low-temperature environments can be effectively improved; according to the invention, two strains of low-temperature-resistant microorganisms, namely new cold-resistant cladosporium and Acremonium, are screened and added, and the two strains of cold-resistant fungi act together to jointly realize the improvement of crop stress resistance. The invention can promote the low-temperature growth of tomatoes and improve the resistance and quality of crops by combining the spraying mode and the flushing mode, and has wide application prospect.
