The invention relates to a method for recycling hemp strain-containing degumming liquid for degumming hemp, relating to a hemp degumming process method and mainly solving the problems of the traditional hemp degumming method, such as long degumming period, low fiber yield, low hemp fiber strength and large sewage discharge during retting. The method disclosed by the invention comprises the following steps of: activating strains used for degumming hemp; carrying out primary seed culturing; carrying out second-degree seed culturing; carrying out third-degree seed culturing; degumming hemp with strains; recycling hemp strain-containing degumming liquid and adding to a new hemp degumming pond, and then adding hemp stalks, sodium chloride and urea, filling clean water into the hemp degumming pond, increasing the temperature for retting and completing the degumming process when a retting terminal point is reached. By adopting the method disclosed by the invention, 50% of waste water discharge can be reduced every day, energy consumed for degumming hemp is saved by 10%-15%; meanwhile, the degumming period of the hemp stalks is shortened to 80-120h, the hemp fiber yield is improved by 3%-5%, the hemp fiber strength is enhanced to 220-280N, and the quality of hemp fiber is improved.
