The beaded high-steep slope greening method is applied to the above-mentioned high-steep slope greening structure. The greening method includes the following steps: S1. Preparation before laying: Use a cutting tool to cut the polyester geotextile 111 into squares.

After a group of vegetation balls (11) is prepared, the water diversion cotton rope (12) is wound onto the outer surface of the series rope (10), and then the series rope (10) together with the water diversion cotton rope (12) is passed through the prepared vegetation balls (11), so that a group of vegetation balls (11) are connected in series; S2, laying work: grab the anchor rod body (81) and place it on the top of the slope body (1), then use a heavy hammer to smash the lower end of the upper fixing mechanism (8) toward the inside of the slope body (1), at this time, through the cooperation of the tapered rod (82), the tapered rod (82) together with the lower end of the anchor rod body (81) can quickly enter the inside of the slope body (1), thereby completing the rapid installation of a single upper fixing mechanism (8), then the upper fixing mechanisms (8) are installed one by one according to the spacing of the pre-splitting blasthole wall groove (2), similarly, the lower fixing mechanism (9) is nailed into the slope body (1) at the lower end in sequence, then the prepared series vegetation ball (11) is placed into the inner surface of the pre-splitting blasthole wall groove (2), and then the two ends of the series rope (10) are respectively wrapped around and bound to the lower end of the upper fixing mechanism (8). The fixing mechanism (9) is used to complete the laying of the vegetation ball (11), and then the upper end of the water diversion cotton rope (12) is inserted into the interior of the butt joint (51), and then the threaded adjustment rod (553) is grasped and driven to rotate inside the fixing seat (552). At this time, the side of the threaded adjustment rod (553) is connected to the threaded connection inside the connecting seat (54), so that the fixing seat (552) drives the movable clamping plate (551) to clamp the end of the water diversion cotton rope (12). Then, through the cooperation of the positioning clamping plate (53) at the end of the fixing rod (52), the positioning clamping plate (53) and the movable clamping plate (551) firmly fix the end of the water diversion cotton rope (12) inside the butt joint (51). When all the water diversion cotton ropes (12) are docked, the overall laying work is completed; S3, maintenance work: turn on the water supply pump (6), when the water supply pump (6) starts to operate, water is pumped into the inside of the diversion pipe (4) through the water pipe (7), and then the water in the diversion pipe (4) is evenly diverted to the multiple water diversion cotton ropes (12) through the cooperation of the butt joint pipe (51), and then the water is gradually retained in the inside of the planting ball (11) through the water diversion cotton ropes (12), so as to achieve the purpose of automatic water supply, thereby increasing the growth rate of plant seeds to a certain extent.
