The invention discloses a biological
fertilizer based on fruit
fermentation, and relates to the technical field of fertilizers, the biological
fertilizer is prepared by fermenting the following raw materials by weight: 2-4 parts of brown
sugar, 6-12 parts of fruit, and 0.06-0.12 part of EM
bacteria. The preparation method comprises the following steps: S1, respectively weighing the brown
sugar, the fruits and the EM
bacteria in parts by weight; s2, adding water, stirring to completely melt the brown
sugar, adding EM
bacteria, continuously stirring to fully mix the EM bacteria in the solution with the brown sugar, and sealing and standing; and S3, adding fruits, uniformly stirring, enabling the fruits to be in full contact with the solution, and sealing and fermenting. The biological
fertilizer prepared by the invention contains various beneficial microorganisms and rich nutritional ingredients, such as macroelements of
nitrogen,
phosphorus,
potassium and the like, various microelements, organic acids and the like; the growth and development of plants can be promoted, the yield of crops can be increased, and the preservation time of fruits can be prolonged.
