Abstract
Description
Technical Field
[0001] This utility model relates to the field of seedling planting technology, and in particular to a root protection device for improving the survival rate of seedlings. Background Technology
[0002] Seedlings are tree seedlings with root systems and trunks. All seedlings cultivated in a nursery, regardless of age, are called seedlings before they are harvested. Seedling types include seedlings grown from seed, vegetatively propagated seedlings, transplanted seedlings, and seedlings left in the nursery bed. Seedlings can also be classified as trees or shrubs; generally, there are more tree seedlings in the north and more shrub seedlings in the south, mainly due to differences in climate. During planting, seedlings often require moisture retention treatment to prevent wilting caused by excessive sun exposure, ensuring growth quality and improving survival rates. However, existing root protection devices for tall seedlings still have the problem of needing to be removed during planting and not effectively supplying water to the seedling roots.
[0003] Therefore, it is essential to invent a root protection device to improve the survival rate of seedlings. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a root protection device for improving seedling survival rate. This solves the problem that existing root protection devices for seedlings still require dismantling during planting and cannot effectively supply water to the seedling roots. The root protection device for improving seedling survival rate includes a root protection frame, a water supply protection frame, a trunk tie, a lower root tie, a support frame, and a soil collection net. The root protection frame and water supply protection frame surround the outside of the seedling's root system, and the trunk tie fixes them to the seedling's trunk. The lower root tie fixes them below the seedling's root system. The support frame is contracted and wraps around the outside of the root protection frame and water supply protection frame, and the soil collection net is fixedly installed between two sets of support frames and wraps around the outside of the root protection frame and water supply protection frame.
[0005] The water supply protection frame includes a water pipe, a root canal, a water inlet, a sealing head, and a water outlet. The root canal is fixedly installed below the water pipe, and the water inlet is fixedly installed at one end of the water pipe. The sealing head is fixedly installed at the other end of the water pipe, and the water outlet is opened on the water pipe and the root canal.
[0006] The root protection frame uses several polyhydroxyalkanoate soft rods, and the root protection frame completely wraps the root system of the seedling after bending itself. The inside of the root protection frame is filled with granular slow-release fertilizer particles. The root protection frame can completely degrade within 40 to 50 days, releasing the slow-release fertilizer particles to the outside.
[0007] The water supply protection frame uses a polylactic acid pipe, and both its inner and outer surfaces are coated with a layer of beeswax. This water supply protection frame works in conjunction with the root protection frame to enclose the roots of the Chinese privet. The water supply protection frame can be connected to an external water supply pipe through its internal water inlet, and the water inside the water protection frame can be output from the water outlet. The outside of the water outlet is wrapped with a starch composite film. The water supply protection frame can be completely degraded within 60 to 70 days.
[0008] The soil collection net uses a strip structure made of carboxymethyl cellulose, and it seals the gap between the root protection frame and the water supply protection frame, and dissolves within 1 to 3 days after contact with water.
[0009] Compared with the prior art, the present invention has the following beneficial effects:
[0010] This utility model's root protection frame uses a flexible polyhydroxyalkanoate rod to wrap around the seedling roots, providing mechanical support and pressure resistance to prevent root deformation or pest and disease attack. The slow-release fertilizer granules inside are released simultaneously with the degradation of the frame, achieving precise fertilization. The degradation of the root protection frame guides root expansion and works in conjunction with the water supply protection frame and soil collection net to ensure uniform water penetration and soil fixation. Ultimately, it completely degrades into harmless substances, providing root protection, growth guidance, and ecological improvement functions. The water supply protection frame uses water pipes and root canals to construct a water delivery network around the roots, achieving precise irrigation through outlet holes. The water supply protection frame, through its own dissolution, ensures both rapid initial water supply and long-term slow-release moisture retention. Working in conjunction with the root protection frame, it creates a humid growth environment, and with the support frame for positioning, it completely degrades without residue, achieving a perfect match between high water efficiency and root growth. The soil collection net is used to temporarily fix the soil around the roots, preventing soil erosion in the early stages of planting. Attached Figure Description

[0018] This utility model provides a root protection device for improving the survival rate of seedlings, including a root protection frame 1, a water supply protection frame 2, a trunk tie 3, a root lower tie 4, a support frame 5, and a soil collection net 6. The root protection frame 1 and the water supply protection frame 2 surround the outer side of the seedling's root system, and the trunk tie 3 fixes the root protection frame 1 and the water supply protection frame 2 to the main trunk of the seedling. The root lower tie 4 fixes the root protection frame 1 and the water supply protection frame 2 below the root system of the seedling. The support frame 5 is contracted and wrapped around the outer side of the root protection frame 1 and the water supply protection frame 2, and the soil collection net 6 is fixedly installed between the two sets of support frames 5 and wrapped around the outer side of the root protection frame 1 and the water supply protection frame 2.
[0019] The water supply protection frame 2 includes a water pipe 21, a root canal 22, a water inlet 23, a sealing head 24, and a water outlet 25. The root canal 22 is fixedly installed below the water pipe 21, and the water inlet 23 is fixedly installed at one end of the water pipe 21. The sealing head 24 is fixedly installed at the other end of the water pipe 21, and the water outlet 25 is opened on the water pipe 21 and the root canal 22.
[0020] The root protection frame 1 uses several polyhydroxyalkanoate soft rods, and the root protection frame 1 completely wraps the root system of the seedling after bending itself. The root protection frame 1 is filled with granular slow-release fertilizer particles. The root protection frame 1 can completely degrade within 40 to 50 days and release the slow-release fertilizer particles to the outside.
[0021] The water supply protection frame 2 uses a polylactic acid pipe, and both the inner and outer surfaces of the water supply protection frame 2 are coated with a layer of beeswax. The water supply protection frame 2 works in conjunction with the root protection frame 1 to wrap the roots of the Chinese privet inside. The water supply protection frame 2 can be connected to an external water supply pipe through its internal water inlet 23, and the water inside the water protection frame 2 can be output from the water outlet 25. The outside of the water outlet 25 is wrapped with a starch composite film. The water supply protection frame 2 can be completely degraded within 60 to 70 days.
[0022] The soil collection net 6 uses a strip structure made of carboxymethyl cellulose, and the soil collection net 6 seals the gap between the root protection frame 1 and the water supply protection frame 2, and dissolves within 1 to 3 days after contact with water.
[0023] This seedling protection device works synergistically using a phased degradation principle: the soil collection net dissolves and stabilizes the soil and improves it within 63 days; the water supply frame 2 achieves precise irrigation through biodegradable pipes; and the root system frame 1 gradually degrades and releases fertilizer. Each component decomposes sequentially, protecting the seedlings while promoting root growth. After 2-3 months, it completely degrades into soil nutrients, significantly improving the survival rate.
[0024] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
