The invention relates to a split nut type satellite-rocket separation seat and a satellite-rocket separation method. The split nut type satellite-rocket separation seat comprises a separation seat mounting plate, a locking assembly, a separation assembly, a pin puller and a satellite body connecting piece, the locking assembly comprises a shell, a hoop cylinder, a connecting cylinder, an unlocking spring, a limiting steel ball, a split nut assembly and a screw rod, the unlocking spring for driving the hoop cylinder to axially move downwards is arranged in the shell, and the pin puller is installed on the side wall of the lower end of the shell; when the pin puller locks the lower end of the hoop cylinder, the limiting steel balls abut against the inner side wall of the hoop cylinder and the outer side wall of the split nut assembly, so that the split nut assembly and the screw rod are matched and clamped. When the pin puller unlocks the lower end of the hoop cylinder, the limiting steel balls are located in the limiting grooves, and clamping between the split nut assembly and the screw rod is relieved; the separation assembly comprises a separation sleeve, a spring push rod and a separation spring, the separation sleeve is installed on the separation base installation plate, the upper end of the separation spring abuts against the upper end of the spring push rod, and the upper end of the spring push rod abuts against the star connecting piece.
