Abstract
Description
Technical Field
[0001] This invention relates to the field of forest tree breeding and seedling technology, specifically to a cutting propagation device and method for *Sapindus mukorossi*. Background Technology
[0002] Cutting propagation has advantages such as maintaining the superior traits of the parent plant and rapid propagation speed, and is widely used in the propagation of forest trees, fruit trees and other plants. With the development of the seedling industry, traditional manual cutting propagation is difficult to meet the needs of large-scale development due to problems such as high labor intensity, low efficiency and inconsistent quality.
[0003] The duckbill-type cutting machine is a widely used cutting propagation device. During operation, the power mechanism drives the swing arm or rotation mechanism to move the duckbill-shaped openable box. When the closed box moves to near the lowest point, it is inserted into the soil. Then, the control mechanism drives the box to open and lifts the opened box, so that the cuttings that have been fed into the box beforehand fall into the soil by gravity, thus completing the cutting.
[0004] Duckbill-type cutting machines still require manual feeding of cuttings one by one into the feeding inlet in real time. The efficiency of operation is limited by the speed of manual feeding, making it difficult to achieve high-speed continuous operation. In addition, the morphology of *Xanthoceras sorbifolium* cuttings varies greatly, with cuttings of different thicknesses, lengths, and degrees of curvature mixed together, which limits the speed of manual identification and feeding. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a cutting propagation device and a cutting propagation method for *Xanthoceras sorbifolium*. The cutting propagation device is not limited by the speed of manual feeding, so as to realize continuous and efficient operation. The cutting propagation method adopts pre-filling to replace manual real-time feeding, realizes the automation of cutting operation, and improves the rooting and survival rate of cuttings.

The seedling component includes a fixed frame, an arc-shaped frame, and a limiting frame. The fixed frame and the limiting frame are connected by the arc-shaped frame. The limiting frame includes a groove. The arc-shaped frame has an indented guide groove that communicates with the groove. A soil divider is installed on the fixed frame or the arc-shaped frame.
[0007] The frame is equipped with a long strip, on which several cuttings are fixed along its length.
[0008] The seedling raising component is configured to move on the field, the soil divider is configured to insert into the soil of the field during the movement and open a continuous soil trench, and the limiting frame is configured to move within the soil trench.
[0009] One end of the long strip is configured to pass through the recessed guide groove and the groove and enter the soil trench, so that the cuttings on the long strip are inserted into the soil trench, and the growing end of the cutting with buds and leaves is kept facing upward.
[0010] As a preferred embodiment of the present invention, the limiting frame includes a first sidewall, a second sidewall, and a groove bottom wall connecting the two, wherein a depth limiting member is installed on the first sidewall facing the second sidewall.
[0011] A limiting band is fixed on the long strip and is arranged parallel to it.
[0012] Wherein, the depth limiting member is configured such that, during the process of the long strip passing through the groove, the bottom side of the depth limiting member is not lower than the top side of the limiting strip.
[0013] As a preferred embodiment of the present invention, an orientation limiting member is installed on the first sidewall facing the second sidewall.
[0014] Wherein, the orientation limiting member is configured such that, during the process of the long strip passing through the groove, the top side of the orientation limiting member is not higher than the bottom side of the limiting strip, and the distance between the orientation limiting member and the depth limiting member is equal to the thickness of the limiting strip.
[0015] As a preferred embodiment of the present invention, a rotating turntable is mounted on the fixed frame, and a detachable support member is mounted in the middle of the turntable.
[0016] The long strip is configured to be wound around the support member, and the long strip is released synchronously when the seedling component moves, so that the long strip maintains a set tension.
[0017] As a preferred embodiment of the present invention, two rotating soil covering discs are installed on the arc-shaped frame or the limiting frame. The two soil covering discs are symmetrically arranged on both sides of the soil trench. The two soil covering discs are configured to push the soil on both sides of the soil trench into and cover the bottom of the inserted cuttings.
[0018] As a preferred embodiment of the present invention, the long strip is made of plant fiber or synthetic biodegradable polymer, and the soil divider includes a wedge-shaped front end and soil dividing side plates that are inclined to both sides.
[0019] As a preferred embodiment of the present invention, the cuttings are tied to a long strip with rope, or the cuttings are glued to a long strip.
[0020] As a preferred embodiment of the present invention, the growing end of the cutting is wrapped with a waterproof layer, the cutting contains at least one bud or shoot, the bottom end of the cutting has a tapered structure, and the surface of the tapered structure is coated with a rooting agent.
[0021] As a preferred embodiment of the present invention, it includes no fewer than three seedling raising components, each of which is mounted on a frame.
[0022] On the other hand, a cutting propagation method is also provided, using any of the aforementioned *Xanthoceras sorbifolium* cutting propagation devices, including the following steps: This allows the seedling raising components to be moved across the field.
[0023] The soil divider on the seedling assembly inserts into the soil of the field during movement, creating a continuous trench in the soil.
[0024] The limiting frame on the seedling assembly and located behind the soil divider enters and moves along the soil trench.
[0025] After passing one end of the long strip through the recessed guide groove and the groove, it is sent into the soil ditch.
[0026] The cuttings on the long strip are inserted into the trench one by one, with the growing end of the cutting with buds and leaves facing upwards.
[0027] Compared with the prior art, the beneficial effects of the present invention are: 1. The *Xanthoceras sorbifolium* cutting propagation device of the present invention uses long strips to fix the cuttings at equal intervals in advance. During the cutting operation, the cuttings are automatically released and continuously enter the soil trench. The operation speed is only limited by the walking speed of the device and the strength of the long strips, and is no longer limited by the speed of manual feeding, thus achieving continuous and efficient operation.
[0028] 2. In the example of the *Xanthoceras sorbifolium* cutting propagation device of the present invention, the depth limiting component ensures that after the long strip enters the groove of the limiting frame, the depth of the cuttings inserted into the soil trench is similar. After the cuttings leave the groove of the limiting frame, the error in the insertion depth of the cuttings is small, which meets the requirements of the cuttings for insertion depth and provides the best soil environment for the rooting of the cuttings.
[0029] 3. In the Xanthoceras sorbifolium cutting propagation device of this invention, the distance between the orientation limiting member and the depth limiting member is equal to the thickness of the limiting band, so that the Xanthoceras sorbifolium cuttings are inserted into the soil in a vertical posture, avoiding the cuttings from being crooked or tilted. After the cuttings take root, the root system develops symmetrically, forming a balanced radial root system, laying a solid foundation for the later growth of Xanthoceras sorbifolium seedlings.
[0030] 4. In the example of the *Xanthoceras sorbifolium* cutting propagation device of the present invention, two soil-covering discs roll and cut the soil as they move forward, and push the soil on both sides of the soil trench towards the middle through the inclined disc surface. The soil is evenly covered at the bottom of the cutting, avoiding uneven local soil covering thickness, so that the cutting is buried at a consistent depth in the soil, and the soil and cutting are in close contact, which is conducive to the cutting absorbing water and rooting.
[0031] 5. The cutting method of the invention example uses a pre-filled long strip to replace manual real-time feeding, which solves the problems of inconsistent orientation and limited cutting efficiency in the cutting operation, realizes the automation of the cutting operation, and improves the rooting and survival rate of the cuttings.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0035] Example 1: Please see Figures 1-6 This embodiment discloses a cutting propagation device for *Vernicia fordii*, including a frame 1. At least three seedling components 2 are installed on the frame 1. Each seedling component 2 includes a fixed frame 201, an arc-shaped frame 202, and a limiting frame 203. The fixed frame 201 and the limiting frame 203 are connected by the arc-shaped frame 202. The limiting frame 203 includes a groove. The top side of the arc-shaped frame 202 has an indented guide groove that communicates with the groove. A soil divider 211 is installed on the bottom side of the fixed frame 201 or the bottom side of the arc-shaped frame 202.
[0036] The fixing frame 201 is provided with a flexible strip 4, and several cuttings 6 are fixed on the strip 4 along its length. The virtual connection line at the bottom of all the cuttings 6 is parallel to the length direction of the strip 4.
[0037] Among them, the seedling component 2 is configured to move on the field, the soil divider 211 is configured to insert into the soil of the field during the movement and open a continuous soil ditch, and the limiting frame 203 is configured to move within the soil ditch.
[0038] One end of the long strip 4 is configured to pass through the recessed guide groove and groove and enter the soil trench, so that the cutting 6 on the long strip 4 is inserted into the soil trench, and the growing end of the cutting 6 with buds and leaves is kept facing upward.
[0039] Furthermore, the long strip 4 is made of plant fiber material or synthetic biodegradable polymer material, or it can be made of paper, hemp rope netting or biodegradable plastic film.
[0040] Furthermore, the soil divider 211 includes a wedge-shaped front end and soil-dividing side plates that are inclined to both sides.
[0041] Furthermore, the cuttings 6 are tied to the long strip 4 with rope, or the cuttings 6 are glued to the long strip 4.
[0042] Furthermore, the growing end of the cutting 6 is wrapped with a biodegradable plastic film or waterproof paper, the cutting 6 contains at least one bud or shoot, and the bottom end of the cutting 6 has a tapered structure, the surface of which is coated with a rooting agent.
[0043] The working process and principle of this embodiment are as follows: The frame 1 is mounted on a traction vehicle via a three-point suspension device, and the traction vehicle moves the seedling component 2 via the frame 1; or the frame 1 is equipped with no fewer than three rotating wheels, and the frame 1 is equipped with a motor or fuel engine that drives at least one wheel to rotate.
[0044] During operation, the frame 1 drives the seedling raising component 2 to move forward on the field. The soil divider 211 first contacts the soil, and its wedge-shaped front end is inserted into the soil. The soil dividing side plate pushes the soil to both sides to form a continuous soil trench with uniform depth. The limiting frame 203 enters the soil trench with the soil divider 211 and moves in the soil trench. The limiting frame 203 maintains the shape of the soil trench and prevents the soil from collapsing on the one hand, and provides a guiding path for the long strip 4 on the other hand.
[0045] Workers guide one end of the long strip 4 through the recessed guide groove and groove into the trench, allowing a portion of the cuttings 6 on the long strip 4 to be inserted into the trench, with the growing end of the cuttings 6 with buds and leaves facing upwards. As the seedling component 2 moves forward, the long strip 4 on the fixing frame 201 is continuously released, and the cuttings 6 enter the trench one by one. Workers manually or mechanically cover the roots of the cuttings 6 in the trench with soil.
[0046] The recessed guide groove of the arc-shaped frame 202 and the groove of the limiting frame 203 make the cutting 6 stand upright. Combined with the positioning function of the long strip 4, the cutting 6 can maintain an upright posture in the soil trench, and the growth end of the cutting 6 is exposed on the ground.
[0047] The crown fruit cutting propagation device in this paper uses long strips 4 to pre-fix the cuttings 6 at equal intervals. During the cutting operation, the cuttings 6 are automatically released and continuously enter the soil trench. The operation speed is only limited by the walking speed of the device and the strength of the long strips 4, and is no longer limited by the manual feeding speed, so as to achieve continuous and efficient operation.
[0048] When the staff fixes the cuttings 6 on the long strip 4, they can easily ensure that the bottom of the cuttings 6 are fixed on the long strip 4 with the same orientation, so that the cuttings 6 can be correctly inserted into the soil.
[0049] Furthermore, the staff tilled the soil in the field before planting the cuttings.
[0050] Furthermore, the trenching depth of the soil divider 211 is adjustable.
[0051] The crown-shaped cutting propagation device described in this article can also be used for propagating other seedlings through cuttings.
[0052] The crown fruit cutting propagation device described in this article can propagate various cutting materials such as hardwood and softwood. Before the cutting operation, the bottom of the cutting branch 6 of the crown fruit cutting propagation device is buried in wet sand or soaked in water.
[0053] The work of fixing the cuttings 6 to the long strip 4 can be shifted to the off-season or indoor environment, thereby achieving pre-filling, which can be completed by seasonal surplus labor or unskilled workers, reducing labor costs.
[0054] The crown-shaped cutting propagation device described in this article can also be used for root cutting propagation.
[0055] Example 2: like Figure 5 and Figure 6 As shown, this embodiment discloses a cutting propagation device for *Xanthoceras sorbifolium*, whose structure is roughly the same as that of Embodiment 1. The difference is that the limiting frame 203 in this embodiment includes a first side wall, a second side wall, and a groove bottom wall connecting the two. A depth limiting member 204 is installed on the first side wall facing the second side wall.
[0056] A limiting band 8 is fixed on the long strip 4 and is arranged parallel to it.
[0057] Among them, the depth limiting member 204 is configured such that during the process of the long strip 4 passing through the groove, the bottom side of the depth limiting member 204 is not lower than the top side of the limiting strip 8.
[0058] Furthermore, the limiting band 8 can be a flexible paper tube, a soft paper strip, or a biodegradable plastic strip.
[0059] The working process and principle of this embodiment are as follows: In the existing technology, the optimal depth for cuttings of *Xanthoceras sorbifolium* is 3.0cm-5.0cm. If the depth is too shallow, the cuttings will easily dry out and die. If the depth is too deep, the oxygen supply to the bottom of the cuttings will be insufficient, which is not conducive to the rooting of the cuttings.
[0060] The depth limiting component 204 ensures that after the long strip 4 enters the groove of the limiting frame 203, the cuttings 6 are inserted into the soil trench at similar depths. After the cuttings 6 leave the groove of the limiting frame 203, the error in the insertion depth of the cuttings 6 is small, which meets the requirements of the cuttings 6 for the insertion depth and provides the best soil environment for the rooting of the cuttings 6.
[0061] Furthermore, the depth limiting member 204 is tilted upwards near the arc frame 202, or the bottom of the depth limiting member 204 near the arc frame 202 is arc-shaped, so that the limiting band 8 can pass under the depth limiting member 204.
[0062] Example 3: like Figure 5 and Figure 6 As shown, this embodiment discloses a cutting propagation device for *Xanthoceras sorbifolium*, whose structure is roughly the same as that of Embodiment 2. The difference is that in this embodiment, an orientation limiting member 205 is installed on the first sidewall facing the second sidewall.
[0063] In this configuration, the orientation limiting member 205 is arranged such that during the process of the long strip 4 passing through the groove, the top side of the orientation limiting member 205 is not higher than the bottom side of the limiting strip 8, and the distance between the orientation limiting member 205 and the depth limiting member 204 is equal to the thickness of the limiting strip 8 in the vertical direction.
[0064] The working process and principle of this embodiment are as follows: The distance between the orientation limiting member 205 and the depth limiting member 204 is equal to the thickness of the vertical direction of the limiting band 8, so that the cuttings of *Xanthoceras sorbifolium* 6 are inserted into the soil in a vertical posture, avoiding the cuttings 6 from being crooked or tilted. After the cuttings 6 take root, the root system develops symmetrically, forming a balanced radial root system, laying a solid foundation for the later growth of *Xanthoceras sorbifolium* seedlings.
[0065] In existing technologies, cuttings taken manually or mechanically using the duckbill cutting method often fail to achieve the desired vertical position, resulting in skewed cuttings. After rooting, the skewed cuttings develop asymmetrical root systems, affecting the upright growth of the seedlings and their later resistance to lodging, which inconveniences subsequent field management such as fertilization, weeding, and pest and disease control.
[0066] Workers can ensure that the limiting band 8 always passes through the gap between the orientation limiting member 205 and the depth limiting member 204 by changing the orientation limiting member 205, the depth limiting member 204, or the limiting band 8 of different widths, which is suitable for cuttings 6 of different thicknesses.
[0067] Example 4: like Figures 2-6 As shown, this embodiment discloses a cutting propagation device for *Vernicia fordii*, whose structure is roughly the same as that of Embodiment 1. The difference is that in this embodiment, a rotating turntable 3 is installed on the fixing frame 201, and a support member 5 is snapped or bolted to the middle of the turntable 3.
[0068] The working process and principle of this embodiment are as follows: The long strip 4 is wrapped around the support 5. When the seedling component 2 moves, the long strip 4 is released synchronously, so that the long strip 4 maintains the set tension.
[0069] Furthermore, the turntable 3 is mounted on the fixed frame 201 via a damping bearing, and the tension of the long strip 4 is adjusted by replacing the damping bearing with a different damping coefficient.
[0070] Example 5: like Figures 1-6 As shown, this embodiment discloses a cutting propagation device for *Xanthoceras sorbifolium*, whose structure is roughly the same as that of Embodiment 1. The difference is that in this embodiment, two rotating soil covering plates 7 are installed on the arc-shaped frame 202 or the limiting frame 203. The two soil covering plates 7 are symmetrically arranged on both sides of the soil trench. The two soil covering plates 7 are configured to push the soil on both sides of the soil trench into the soil trench and cover the bottom of the inserted cuttings 6.
[0071] Furthermore, the two soil-covering discs 7 are arranged in a V-shape, wider at the front and narrower at the back, in the direction of travel.
[0072] The working process and principle of this embodiment are as follows: As the seedling component 2 moves forward, the two soil-covering trays 7 roll and cut the soil, and push the soil on both sides of the trench towards the center through the inclined tray surface. The soil is evenly covered at the bottom of the cutting 6, avoiding uneven local soil thickness, so that the cutting 6 is buried at a consistent depth in the soil. The soil and the cutting 6 are in close contact, which is conducive to the cutting 6 absorbing water and rooting.
[0073] Furthermore, a soil compaction wheel is also installed on the arc-shaped frame 202 or the limiting frame 203 to compact the soil covering the two soil covering discs 7.
[0074] Example 6: like Figure 1As shown, this embodiment discloses a cutting propagation device for *Xanthoceras sorbifolium*, whose structure is roughly the same as that of Embodiment 1. The difference is that the soil divider 211 is replaced by a rotating trencher in this embodiment. The rotating trencher includes a rotating cutter disc and a power mechanism. The power mechanism drives the rotating cutter disc to rotate, and the rotating cutter disc cuts trenches in the untilled soil.
[0075] The power source is either an electric motor or a fuel engine.
[0076] Example 7: like Figures 1-6 As shown, this embodiment discloses a cutting propagation method, applied to any one of the cutting propagation devices of *Xanthoceras sorbifolium* from Embodiment 1 to Embodiment 6, comprising the following steps: Move the seedling component 2 on the field.
[0077] The soil divider 211 on the seedling component 2 is inserted into the soil of the field during the movement, creating a continuous trench in the soil.
[0078] The limiting frame 203, located on the seedling component 2 and behind the soil divider 211, enters and moves along the soil ditch.
[0079] After passing one end of the long strip 4 through the recessed guide groove and the groove, it is sent into the soil ditch.
[0080] The cuttings 6 on the long strip 4 are inserted into the trench one by one, with the growing end of the cuttings 6 with buds and leaves facing upwards.
[0081] This cutting method uses pre-filled long strips to replace manual real-time feeding, which solves the problems of inconsistent orientation and limited cutting efficiency in cutting operations, realizes the automation of cutting operations, and improves the rooting and survival rate of cuttings.
[0082] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
