Description

Technical Field

[0001] This invention relates to the field of seedling container technology, specifically to seedling containers for ecological restoration of difficult sites. Background Technology

[0002] Container seedling cultivation is a primary method for cultivating seedlings for ecological restoration in challenging sites due to its advantages such as high survival rate, lack of seasonal limitations, and ease of transportation. However, the inherent root entanglement problem of container seedlings has always been a core bottleneck restricting their afforestation effectiveness: lateral roots grow along the inner wall of the container, forming strangler roots that prevent the root system from expanding outwards normally after planting, leading to poor long-term growth, susceptibility to lodging, and a generally low survival rate of less than 60% after planting in the wild, as well as poor ecological stability in the later stages.

[0003] To address the root system problem in container seedlings, existing technologies primarily employ the following solutions:

[0004] (1) Manual root pruning method: The seedlings are manually removed from the container and the coiled lateral roots are trimmed with scissors. This method is extremely inefficient (100-150 seedlings / person / hour) and relies entirely on manual experience. It is highly subjective and prone to accidentally cutting the main root and absorbing fibrous roots, which leads to weak seedling growth and prolonged seedling recovery period.

[0005] (2) Mechanical root cutting method: All roots are cut off from the bottom or side of the container at once using a root cutting machine. This method uses a one-cut mode and cannot distinguish the root diameter. It will cut off a large number of thick lateral roots and absorbing fibrous roots that are crucial to the growth of seedlings. The healing time after the roots are cut is as long as 10-15 days, which seriously affects the growth of seedlings. Summary of the Invention

[0006] The purpose of this invention is to provide a seedling container for ecological restoration of difficult sites in order to solve the above problems.

[0007] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0008] A seedling container for ecological restoration of difficult sites includes a water collection tray, a seedling bucket is mounted on the top of the water collection tray, an inner mesh cylinder is provided inside the seedling bucket, a through hole is opened through the bottom of the inner mesh cylinder, and a bottom support is slidably connected to the bottom of the inner mesh cylinder, with the bottom support penetrating through the through hole.

[0009] The inner mesh cylinder has several guide holes arranged in a ring. Each guide hole has a connecting slot on both sides. The inner wall of the connecting slot is provided with a stop block. An embedded ring is inserted into the guide hole. The inner diameter of the embedded ring is 3-3.5mm and the outer diameter is 5-6mm. The embedded ring has a receiving ring groove inside. Sliding openings are opened through both sides of the embedded ring. An elastic sleeve is provided inside the receiving ring groove. The inner diameter of the elastic sleeve is the same as that of the embedded ring. When the elastic sleeve is not under force, it is elliptical. Each side of the elastic sleeve is provided with a sliding rod and a driving rod. The sliding rod passes through the sliding opening and is inserted into the connecting slot. A groove is opened on the outer side of the sliding rod. When the elastic sleeve is circular, the groove corresponds to the stop block. The stop block is located between the sliding rod and the driving rod.

[0010] The bottom of the guide root mesh is provided with two sets of sliding grooves. A top block is slidably connected inside the sliding groove. The contact surface between the top block and the drive rod is an inclined surface. Several top blocks are connected by a connecting rod, which extends through to the top of the inner mesh cylinder.

[0011] Furthermore, the elastic sleeve is composed of an elastic metal inner ring and an elastic rubber sleeve. The cross-section of the elastic rubber sleeve is C-shaped. The sliding rod and the drive rod are fixedly installed on the elastic metal inner ring. Both sides of the inner wall of the elastic metal inner ring are provided with inner cutting arc blades.

[0012] Furthermore, the base support is arranged in a funnel shape.

[0013] Furthermore, a transmission column is provided on the outer side of the bottom support, and a pedal is hinged to the outer side of the water collection chassis. A transmission guide sleeve is provided at one end of the pedal near the bottom support, and the transmission guide sleeve is sleeved on the transmission column. The length of the transmission guide sleeve is greater than the diameter of the transmission column.

[0014] Furthermore, the top of the water collection chassis is provided with several supporting members in a ring shape, and the seedling bucket is mounted on the top of the water collection chassis through several supporting members. The pedal passes through the spacing between adjacent supporting members and is connected to the transmission column for transmission.

[0015] Furthermore, the cross-section of the inner mesh cylinder is arranged in the form of a regular polygon.

[0016] Furthermore, a drive ring is provided at the top of the inner mesh cylinder, and several connecting rods are fixedly connected to the bottom of the drive ring.

[0017] Furthermore, a handle is provided on the outer side of the drive ring, and the handle is arranged in a mesh pattern.

[0018] Furthermore, a mounting flange is provided at the bottom of the water collection chassis.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention utilizes the physical principle of elliptical elastic sleeves triggering locking to achieve three-level precise root screening: automatically cutting off risky lateral roots with coiled roots of 0.5-3mm, automatically retaining absorbing fibrous roots <0.5mm, and automatically allowing thick lateral roots >3mm. This completely solves the problem of the one-size-fits-all approach in existing technologies and completely eliminates the subjective error of manual root cutting.

[0021] 2. The funnel-shaped base of this invention guides the taproot to grow vertically downwards along the center, and controls the taproot length through air pruning, cultivating a composite root system with a deep taproot and dense fibrous roots. Compared with traditional flat-bottomed containers, the taproot length and the number of fibrous roots are increased, allowing it to quickly penetrate shallow soil layers in rocky desertification areas and dry soil layers in arid regions after planting, absorbing deep groundwater and improving the survival rate of planting in the field.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] Example 1, as Figures 1-6As shown, the seedling container for ecological restoration of difficult sites includes a water collection tray 1, a seedling bucket 2 is mounted on the top of the water collection tray 1, an inner mesh cylinder 3 is installed inside the seedling bucket 2, a through hole is opened through the bottom of the inner mesh cylinder 3, and a bottom support 4 is slidably connected to the bottom of the inner mesh cylinder 3, with the bottom support 4 passing through the through hole.

[0031] The inner mesh cylinder 3 has several guide mesh holes 31 arranged in a ring. Both sides of the guide mesh holes 31 are provided with connecting slots 32. The inner wall of the connecting slots 32 is provided with a stop block 33. An embedded ring 7 is inserted into the guide mesh holes 31. The inner diameter of the embedded ring 7 is 3-3.5mm and the outer diameter is 5-6mm. The inside of the embedded ring 7 is provided with a receiving ring groove. The two sides of the embedded ring 7 are provided with sliding openings 71. The inside of the receiving ring groove is provided with an elastic sleeve 8. The inner diameter of the elastic sleeve 8 is the same as that of the embedded ring 7. When the elastic sleeve 8 is not under force, it is in an elliptical state. Both sides of the elastic sleeve 8 are provided with a sliding rod 81 and a driving rod 83. The sliding rod 81 passes through the sliding opening 71 and is inserted into the connecting slot 32. The outer side of the sliding rod 81 is provided with a groove 82. When the elastic sleeve 8 is circular, the groove 82 corresponds to the stop block 33. The stop block 33 is located between the sliding rod 81 and the driving rod 83.

[0032] Two sets of sliding grooves 34 are provided at the bottom of the guide root mesh 31. A top block 35 is slidably connected inside the sliding groove 34. The contact surface between the top block 35 and the drive rod 83 is an inclined surface. Several top blocks 35 are connected by a connecting rod 36, which extends through to the top of the inner mesh cylinder 3.

[0033] The base support 4 is funnel-shaped. The funnel-shaped conical slope guides the taproot to grow naturally towards the lowest point in the center, preventing the taproot from growing horizontally or coiling against the wall. A distance of at least 5cm is maintained between the bottom of the base support 4 and the water collection tray 1, allowing the protruding taproot to naturally sever, thus controlling its length. A drive column 41 is located on the outer side of the base support 4, and a foot pedal 5 is hinged to the outer side of the water collection tray 1. A drive guide sleeve 51 is located at the end of the foot pedal 5 near the base support 4, and the drive guide sleeve 51 is fitted onto the drive column 41. The length of the drive guide sleeve 51 is greater than the diameter of the drive column 41. Several support members are arranged in a ring at the top of the water collection tray 1. The seedling bucket 2 is supported on top of the water collection tray 1 through these support members. The foot pedal 5 passes through the gap between adjacent support members and is connected to the drive column 41. The inner mesh cylinder 3 has a regular polygonal cross-section. A drive ring 6 is located at the top of the inner mesh cylinder 3, and several connecting rods 36 are fixedly connected to the bottom of the drive ring 6. A handle with a mesh-like design is provided on the outer side of the drive ring 6. A mounting flange is provided at the bottom of the water collection tray 1. The seedling containers can be fixed to the seedling rack in rows using the mounting flange, and all the pedals 5 can be connected together with a long rod, allowing multiple seedling operations to be completed simultaneously.

[0034] For 1-2 year old seedlings struggling in growing in open locations, container seedlings typically have over 95% lateral root diameters concentrated in the 0.1-3 mm range, with the thickest lateral root generally not exceeding 4 mm. Lateral roots exceeding 4 mm account for less than 1% and only appear in large containers or seedlings with a cultivation period exceeding 2 years. Although lateral roots with a diameter of 0.5-3 mm are few in number, they are the only root system prone to forming root clumps. Fibrous roots smaller than 0.5 mm are the main absorption organs, while thick lateral roots larger than 3 mm have a long healing time, and cutting them will severely affect seedling growth. Therefore, in the actual process of pruning lateral roots, selective pruning is necessary. Manual pruning is too inefficient and too subjective, easily leading to incorrect pruning.

[0035] Therefore, through the design of this invention, the seedlings are planted in the inner net cylinder 3. The root guide mesh 31 plays a horizontal guiding role, allowing the lateral roots to grow outward horizontally through the elastic sleeve 8 in the root guide mesh 31. When the lateral root exceeds 3mm, it will press the elastic sleeve 8 from an elliptical shape into a circle. At this time, the groove 82 corresponds to the stop block 33. The thickest lateral root generally does not exceed 4mm, ensuring that the elastic sleeve 8 does not excessively affect the thick lateral root. When it is necessary to prune the lateral root, by stepping on the pedal 5, the pedal 5 drives the bottom support 4 to rise. The bottom support 4 lifts the seedling relative to the inner net cylinder 3. The lateral root exceeding 3mm causes the elastic sleeve 8 and the embedded ring 7 to detach from the root guide mesh. Hole 31, the radius of the root guide mesh 31 is large enough to prevent root jamming. The elastic sleeves 8 and embedded rings 7 in the other root guide mesh holes 31 remain inside. Under the restriction of the stop block 33, the sliding rod 81 is stably inserted into the connecting slot 32 and will not disengage. Then, the drive ring 6 is pulled upward, and the drive ring 6 drives the top block 35 to rise through the connecting rod 36. The top block 35, through the drive rods 83 on both sides, causes the elastic sleeves 8 to squeeze inward. The elastic sleeves 8 clamp 0.5-3mm lateral roots, but cannot clamp thinner lateral roots. Then, the pedal 5 is pressed down, and the seedling continues to rise relative to the inner mesh cylinder 3, breaking off the 0.5-3mm lateral roots, achieving precise root cutting. During subsequent transplanting, the elastic sleeves 8 and embedded rings 7 can be cut off without affecting later survival. The embedded ring 7 is made of plastic to reduce costs. In this embodiment, the inner wall of the elastic sleeve 8 can be provided with protruding points to improve the clamping force.

[0036] Example 2, based on the above examples, further includes an elastic sleeve 8 composed of an elastic metal inner ring 84 and an elastic rubber sleeve 85. The cross-section of the elastic rubber sleeve 85 is C-shaped with a small opening, and the two ends of the opening are in contact with each other. The elastic rubber sleeve 85 is made of aging-resistant EPDM rubber with added ultraviolet absorbers, and its service life can reach more than 5 years. The slide rod 81 and the drive rod 83 are fixedly installed on the elastic metal inner ring 84. Both sides of the inner wall of the elastic metal inner ring 84 are provided with inner cutting arc blades 86.

[0037] This embodiment provides another elastic sleeve 8 structure. When the lateral root exceeds 3mm, the lateral root will press the elastic sleeve 8 from an elliptical shape into a circle. At this time, the elastic rubber ring 85 stably forms a C-shape, which wraps the inner cutting arc blade 86 inside. The elastic rubber ring 85 blocks the lateral root and the inner cutting arc blade 86, forming effective protection to prevent the lateral root from being cut. The embedded ring 7 in the other root guide mesh 31 is still there, and the lateral root is relatively thin. Pulling the drive ring 6 upward, the drive ring 6 drives the top block 35 to rise through the connecting rod 36. The top block 35, through the drive rods 83 on both sides, causes the elastic sleeve 8 to be squeezed inward. The elastic metal inner ring 84 and the elastic rubber sleeve 85 are squeezed inward together, just like when a tire is squeezed in the middle. The opening of the elastic rubber sleeve 85 increases and expands outward, so that the inner cutting arc blade 86 can press against the lateral root and cut into the lateral root. Then, continue to press the pedal 5 down, and the seedling continues to rise relative to the inner mesh cylinder 3, pulling off the 0.5-3mm lateral root, so that it can be precisely cut at the cutting position, and the root cutting effect is better.
