The invention relates to the field of healthy crayfish culturing, especially to a greenhouse graded crayfish seed rearing method, and belongs to the technical range of agriculture. The method comprises the steps including greenhouse preparation, crayfish seed throwing in, crayfish seed feeding and reinforced culturing. Artificially bred crayfish seeds in the uniform specification of 1cm are throwninto a soil pool in a greenhouse in October to November in the density of 150-200 thousands per mu, plankton in the water are cultivated, animal forages as surimi are added, food is abundant, the temperature of the greenhouse is proper, the benthophyte Hydrilla verticillata grows vigorously to provide sufficient shelters, a nanometer micropore aerator in the soil pool of the greenhouse is used cooperatively, dissolved oxygen in the water body is sufficient, and the crayfish seeds in 1cm can grow rapidly to about 3cm after 25-30 days of reinforced cultivation, the survival rate of the seeds reach more than 85%, and th
