s7, spraying and planting a base material: firstly, spraying and planting a base layer, placing a ground fixing plate (1) on the slope top ground after the base layer is sprayed and planted, fixing the ground fixing plate by using a balancing weight (5) or directly fixing the base layer on the ground by using a bolt, placing a transverse plate (201) and a vertical plate (202) on a slope surface, connecting the transverse plate (201) and the vertical plate (202) by using a transverse connecting block (203), fixing a guide rail (301) and a screw rod supporting seat (302) of a moving mechanism on the slope surface fixing plate, and the like, simultaneously spraying a base material of a surface layer into a rectangular block (6) on the ground, dividing the base material of the surface layer into independent units, then placing a plurality of rectangular blocks (6) into a rectangular block placing frame (4), and then placing the rectangular block placing frame (4) onto the moving mechanism, namely inserting limiting rods (402) at the bottoms of connecting blocks II (401) at two ends of the rectangular block placing frame (4) into limiting grooves (306) on connecting blocks I (305) of a sliding block (304);
before the rectangular block placing frame (4) is placed on the moving mechanism, the telescopic rods (308) are in a retraction state, the baffle (309) does not extend into the notch of the side wall of the rectangular block placing frame (4), after the rectangular block placing frame (4) is placed on the moving mechanism, the two telescopic rods (308) corresponding to the two ends of the telescopic rod fixing plate (307) up and down extend outwards, when the baffle (309) extends into the notch, the upper baffle (309) clamps the bottom of the rectangular block (6) located above, and the lower baffle (309) clamps the bottom of the rectangular block (6) located below;
the screw rod (303) is driven by a motor to rotate, the sliding block (304) is driven to move forwards, when the screw rod moves to the position above one rectangular block placing groove (206), the baffle (309) positioned below is contracted, the bottom of the rectangular block (6) positioned below is not limited, and the screw rod can fall into the rectangular block placing groove (206), the lapping edges of two ends of the rectangular block (6) are lapped on the edge of the rectangular block placing groove (206), at the moment, the baffle (309) positioned below outwards extends into the groove opening, the baffle (309) positioned above is contracted, the bottom of the rectangular block (6) positioned above is not limited, and the rectangular block (6) positioned above can fall into the baffle (309) positioned below, when the screw rod moves to the position above the next rectangular block placing groove (206), the baffle (309) positioned below is contracted, the bottom of the rectangular block (6) positioned below is not limited, and the screw rod can fall into the current rectangular block placing groove (206), and the process is repeated;
the time interval between the spray planting of the base material and the placement of the rectangular blocks (6) of the surface layer is less than 4 hours, and the slope surface is fully soaked before the spray planting of the base layer;
s8, maintenance management: and (4) performing seedling maintenance management for at least 60 days after the spraying of the base material, wherein the content comprises covering and soil moisture conservation, irrigation, local defect repair and the like.
