The invention discloses a method for utilizing formamide deionized for promoting somatic embryogenesis of cunninghina lanceolata. Embryonic calluses with a good subculture state are inoculated to a somatic embryo inducing culture medium, dark culture is conducted in an incubator, and the somatic embryogenesis of the cunninghina lanceolata is induced and promoted, wherein a 1/2DCR serves as a basicculture medium of the somatic embryo inducing culture medium, and FD with the concentration not exceeding 0.1134 is added. According to the method, as is proved by experiments, the low-concentrationFD can accelerate the somatic embryogenesis of the cunninghina lanceolata, and the high-concentration FD can cause browning death of the embryonic calluses of the cunninghina lanceolata. When the FD concentration is 0.1134, the somatic embryogenesis time can be shortened to 35 d. The somatic embryogenesis of the cunninghina lanceolata can be efficiently and quickly promoted, and the practicabilityis very high.
