The invention discloses a telescopic jack stepping rewinding type reel sprinkler control method. A telescopic jack stepping rewinding type reel sprinkler includes a machine frame, a clamping-channel type reel, a sprinkling device and a stepping drive device; the clamping-channel type reel is provided with a clamping channel which is arranged in the peripheral direction; and the stepping drive device includes a lifting cylinder, an upper caliper and a lower caliper, and the upper caliper and the lower caliper are matched to be installed at the clamping channel in a clamping mode. The telescopicjack stepping rewinding type reel sprinkler control method includes the steps that periodic lifting movement of a piston rod can be realized by driving a lifting cylinder with pressure water, therebydriving the upper caliper to vertically move to occlude the clamping channel of the clamping-channel type reel at intervals, so that a sprinkling PE pipe can be automatically collected through periodic rewinding of the clamping-channel type reel; and the lower caliper can prevent the clamping-channel type reel from reversely rewinding in the clamping-channel type reel periodic rewinding process,park vegetation can be conveniently sprinkled, uniform distribution of water in sprinkled soil and uniform irrigation can be realized under the premise of saving water resource, and the telescopic jack stepping rewinding type reel sprinkler control method is especially suitable for park sprinkling.
