5. A construction method for a modular anti-lodging drip irrigation fixing net for roof gardens according to any one of claims 1 to 4, characterized in that: It includes the following steps: Step 1: Design and manufacture the fixed net (1) components: First, build the planting pool on the roof. Then, design the shape, size and grid size of the fixed net (1) according to the size of the planting pool, the number, size and location of the trees and shrubs to be planted, and the irrigation range factors. The grid that frames the main trunk of the tree is larger than the ground diameter of the seedling and smaller than the diameter of the soil ball (7) of the seedling root system. For trees that are easy to fall or seedlings with small specifications, add diagonal poles (11.2) locally to make the overall grid design economical. Make the fixed net (1) components according to the design. Step 2: Install the structural connector (35) inside the planting pool wall (4) according to the design method; Step 3: Lay the roof garden base layer (9) according to the conventional roof garden construction steps. The specific steps are as follows: perform roof waterproofing treatment, lay root-blocking waterproof membrane, set up drainage layer, and lay filter layer in sequence. After the roof garden base layer (9) is laid, fill the planting substrate to the height of the connecting structure and completely bury the soil balls (7) of the trees and shrubs to be planted in the planting substrate. Step 4: Assemble the fixed net (1): With drip irrigation function: According to the design of the fixed net (1), connect the fixed rods (11) with drip irrigation function into a net shape through the fixed joint (12), lay it on the planting substrate, then set the vertical pipe (25) and micro-sprinkler (21) on the fixed rod (11), and connect the fixed net (1) to the main water pipe (23), and then connect the main water pipe (23) to the controller (22) and the water source (24); Without drip irrigation function: According to the design of the fixed net (1), connect the fixed rods (11) into a net shape through the fixed joint (12), and lay it on the planting substrate; Step 5: Connect the connecting ring (31) on the fixing joint (12) at the corner of the fixing net (1) to the connecting buckle (33) on the connecting buckle sleeve (34) using the connecting strap (32). Each corner needs to be connected. The specific operation is as follows: fix one end of the connecting strap (32) on the connecting ring (31), pass the other end through the connecting buckle (33) and tighten it. Then use a D-ring or screws to fix the length to ensure that the entire fixing net (1) is tensioned. Step 6: Lay down the remaining top layer of planting substrate and plant shallow-rooted herbaceous plants and low shrubs; Step 7: If you need to replace the plants or make other modifications, first clean the upper planting substrate, disassemble the fixing net (1) and connecting buckle sleeve (34) components, and reassemble them according to steps 3-6 above after the replacement or modification is completed.

6. A construction method for a modular anti-lodging drip irrigation fixing net for roof gardens according to claim 5, characterized in that: The specific installation method of the structural connector (35) in step 2 is as follows: When the structural connector (35) is connected to the planting pool wall (4), the structural connector (35) and the connecting sleeve (34) are fixed on the inner wall at each corner of the planting pool. The fixing height is 10-15cm below the design height of the planting substrate layer (6). First, the base (351) of one structural connector (35) is fixed to the inner wall of one side of the planting pool with expansion bolts. When fixing, a gasket (354) is placed between the planting pool wall (4) and the base (351). Then, the connecting sleeve (34) is screwed into the connecting rod (353). Then, the connecting rod (353) of the other structural connector (35) is screwed into the connecting sleeve (34). After adjusting the overall length, the base (351) of the second structural connector (35) is fixed to the inner wall of the other side of the planting pool with expansion bolts to form a stable triangular structure and ensure that the connecting sleeve (34) is horizontal. When the structural connector (35) is connected to the roof structure layer (5), the anchor construction method is used to vertically fix the connecting anchor (355) on the roof structure layer (5). The construction steps are as follows: first, drill holes at the fixed position of the connecting anchor (355). The depth of the hole is adjusted according to the overall length of the connecting anchor (355). The longer the length, the greater the depth of the hole. Then, insert the connecting anchor (355) and place it in the center of the hole. Insert the grouting pipe to inject grout. After the grout solidifies, the fixing of the connecting anchor (355) is completed. After the fixing is completed, waterproofing treatment should be done at the anchor hole. Screw the connecting buckle sleeve (34) into the connecting anchor (355) so that the connecting buckle (33) is placed 10-15cm below the designed height of the planting substrate layer (6).
