Seedling support frames are specialized tools used in landscaping projects to secure newly planted seedlings. Their core function is to achieve stable trunk fixation through mechanical structures. The main structure includes support rods, fixing plates, and adjustment devices.
Patent technology shows that modern support frames generally employ multi-level locking mechanisms, adjustable sliding groove systems, and spiral retractable rod designs, adaptable to the need for fixing seedlings with diameters of 20-60cm.
Support frame types include single-pillar, triangular support, and grid-like fixing, among which triangular pillars are widely used due to their strong stability. According to the utility model patent, innovative designs include key technological breakthroughs such as arc-shaped push plates to enhance clamping force, hinged support rods for adjustable angles, and telescopic rod structures that reserve growth space. In typhoon-prone areas, steel pipe reinforcement is required, with the support height typically controlled at 1/3 to 2/3 of the tree height. Removal is generally done two years after planting.
