Method for continuously breeding turbellarian worms at low cost

The invention discloses a method for continuously breeding turbellarian worms at low cost and a breed conservation method for obtaining genetic progenies at low cost. The method is used for feeding nematodes, and comprises the following steps: S1, placing a plurality of nematodes and/or nematode eggs in a solid culture medium for breeding and culturing; s2, a turbellarian worm breeding tank is arranged below the solid culture medium, the release amount of nematode bait in the solid culture medium in the breeding tank is controlled through a slow-release adjusting body, and the bait feeding interval time is prolonged. The method has the obvious advantages of being easy to operate and low in cost, a solid culture medium-nematode-turbellarian worm circulating culture mode is achieved, dynamic balance is achieved by optimizing the number of nematode and turbellarian worm groups, a three-stage ecological culture system for culturing nematode and culturing turbellarian worm through the culture medium is achieved, a
