Abstract

The invention relates to a preparation method of an efficient liquid biofertilizer, comprising the following steps: (1) using organic wastewater as a culture medium, adding nutrients essential for growth and reproduction of microbes, carrying out sterilization, and fermenting after sterilization so as to obtain an initial fermentation broth; (2) cooling the initial fermentation broth to room temperature, and adjusting pH of the solution to 5.5-6.6 by adding a pH buffer agent into the fermentation cylinder; (3) inoculation: pouring a bacterial strain which accounts for 5-10% of mass of the pH-regulated fermentation broth into the pH-regulated fermentation broth obtained in the Step (2), and culturing for 120-160 h so as to obtain a microbial agent, wherein mass ratio of the bacterial strainto the fermentation broth is as shown in the specification; and (4) adding a nitrogenous fertilizer, a phosphate fertilizer, a potash fertilizer and a plant regulator into the microbial agent, and filling to obtain the efficient liquid biofertilizer. The efficient liquid biofertilizer of the invention can help improve soil structure and treat soil hardening, thus changing waste into valuable things.
