Method for tissue culturing and quick propagation of sugarcane with intermittent immersion bioreactor

The invention provides to a method for tissue culturing and quick propagation of sugarcane with an intermittent immersion bioreactor, which is characterized in that: the method performs propagation culture and rooting culture by transplanting detoxicated sugarcane plants, serving as materials, cultured by generations from induced sprouts of sugarcane stem tip tissues into the intermittent immersion bioreactor. In the intermittent immersion bioreactor, a culture temperature is 29 DEG C; the illumination intensity is 1,500 Lx and the illumination time is 16 hours; an intermittent culture condition is to culture for 3min every 3h and to root for 3min every 6h; the first generation can be propagated to 40 times; after rooting is completed, a proper hardening plantlet treatment is performed; and plantlets are transplanted and the survival rate is about 85 percent. The set of system is high in automation degree, has a much higher multiplication rate than that of a traditional tissue culture method, saves labour cos
