The invention discloses a method for delaying the hatching of F1 hybrids of incubated silkworm eggs in hatching. The F1 hybrids of silkworm eggs in hatching are subjected to three-section type low-temperature preservation, and graine embryos of the F1 hybrids of silkworm eggs of mulberry silkworms are grown through the hatching processing to a body pigmentation stage, and then are continuously preserved at the certain environment temperature; 10 silkworm eggs boxes are bundled by a plastic rope, and put in a double-layered black cloth bag wrung after being soaked in water, and the silkworm eggs in the 10 silkworm eggs boxes are uniformly shaken and horizontally placed; and the black cloth bag wrapping the silkworm eggs boxes is put in a certain temperature environment for preservation, and then is transferred in a refrigerator for refrigeration. Under the condition of not influencing the hatching rate and the growth of the F1 hybrids of hatched silkworm eggs, the gathering data of newly hatched silkworms is delayed by 1 to 25 days so as to be favorable for adjusting the production data of silkworm cocoons, and to reduce the influence of the natural disaster and the temperature anomaly on the growth of mulberry leaves and the influence of the silkworm poisoning and the silkworm disease and other disasters on the growth of the silkworm cocoons, and the method disclosed by the invention is a safe emergency disposal technology for sericulture, and has the hatching rate of more than 95%.
