Description

Technical Field

[0001] The invention belongs to the technical field of pitaya grafting, and in particular relates to a pitaya grafting method and a cutting device thereof. Background Art

[0002] The purpose of current pitaya grafting is to transplant the branches or buds of superior varieties onto another plant (stock) so that they can grow together and form an independent new plant. The key technology is how to correctly select and utilize the stock so that the scion and stock have a strong affinity, and add favorable grafting methods to improve the grafting survival rate and the quality and yield of the later stage. At present, the grafting methods of pitaya include single bud V-shaped insertion or embedding grafting, cleft grafting, plug grafting, flat grafting, etc. Different grafting methods have their advantages and disadvantages. Different people have different operations for each grafting method, but the purpose is the same: to improve the grafting survival rate.

[0003] The advantage of the grafting method is that the contact area of the fleshy part is large and the incision is easy to heal. The disadvantage is that there are no special cutting tools, especially when processing the scion, blades are used for cutting, which has low processing efficiency. The hands are prone to fatigue and cramps after operating the blade for a long time. Therefore, the grafting method for pitaya needs to be optimized and improved and a special cutting device needs to be designed. Summary of the Invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention invents a pitaya grafting method and a cutting device thereof.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A cutting device for a pitaya grafting method comprises a base, a scion placement convex strip, a slip ring, a sliding device and a cutting line, wherein the scion placement convex strip is fixedly provided on the upper surface of the base, the slip ring is fixedly provided on the right end of the base; the sliding device is slidably provided on the slip ring; one end of the cutting line is fixedly provided on the inner side surface of the slip ring, and the other end of the cutting line is fixed on the front end inside the sliding device; the fixed positions of the two ends of the cutting line are on the same plane.

[0007] The main innovation of the present invention is to use a rotating cutting wire to ring-cut the scion so that the fleshy cut at the rear end is independent and convenient for subsequent separation, meeting the use requirements of different scions of different sizes and shapes, and achieving the purpose of fast cutting and avoiding hand fatigue.

[0008] Furthermore, it also includes a ball head seat, and the two ends of the cutting line are fixedly installed through the ball head seat. The function of the ball head seat is to prevent the cutting line from twisting itself during the rotation of the cutting line, which may cause the cutting line to be tightened and broken due to excessive twisting after long-term use.

[0009] Furthermore, the length of the cutting line is equal to the diameter of the inner side of the slip ring. The cutting line cannot be too short, otherwise the sliding device cannot rotate. If it is too long, it will cause a burden and hinder the sliding device from rotating.

[0010] Furthermore, it also includes a rotating separation device. The sliding device is provided with a rotating separation device for separating the cut meat from the wood fiber tube, so that the cutting is achieved in one step, and the cut meat is rotated and separated from the wood fiber tube during the withdrawal process.

[0011] Furthermore, the rotary separation device includes a connecting rod, a bearing, a roller, a separation rod and a rotary locker. The connecting rod is fixedly installed on the sliding device, and the front end of the connecting rod is fixedly provided with a bearing, and the bearing and the slip ring are concentric circles; a roller is rotatably provided in the bearing; three separation rods are provided in a circular array in front of the roller; the rotary locker is provided on the connecting rod, and the rear end of the roller is provided with a tooth groove for use with the rotary locker. When in use, the roller can be freely rotated or locked as needed. When locked, the separation rod will cause the cut meat to rotate to separate it from the wood fiber tube.

[0012] A pitaya grafting method using a cutting device comprises the following steps:

[0013] (1) Select a rootstock with a well-developed root system and strong growth. Use a cutting knife to cut the top horizontally, and then insert a round hollow tube along the wood fiber tube to dig a cylindrical hole;

[0014] (2) Collecting strong branches that are mature in the current year, have full buds, and are free of quarantine diseases and insect pests from high-quality and high-yield mother plants as scions, placing the scions on the cutting device, rotating the sliding device, and using the cutting line to cut the fleshy ring 1.5 to 2.0 cm at the rear end of the scion, and then locking the roller on the rotating separation device when withdrawing the line. During the withdrawal process, the cut fleshy flesh is separated from the wood fiber tube, and finally the separated fleshy flesh is removed;

[0015] (3) Disinfect the cuts of the stock and scion with 75% alcohol. After disinfection and drying, apply a layer of 20-30% aminoethyl hexanoate on the cuts, and then ventilate and let stand for 15-20 minutes.

[0016] (4) Use a cotton swab to absorb the liquid in the cylindrical hole on the rootstock, and then insert the wood fiber tube exposed at the rear end of the scion into the cylindrical hole on the rootstock;

[0017] (5) Use sterilized transparent plastic film to fix the scion and wrap it tightly;

[0018] (6) Place the grafted rootstock on the seedbed for cultivation.

[0019] Furthermore, the rootstock and scion are excellent varieties with strong grafting affinity. Varieties with strong affinity will have a higher grafting survival rate, and the resulting plants will have better yield and quality.

[0020] Furthermore, the length of the scion is 6.0 to 7.0 cm, and the scion has at least three buds, so that the scion can consume enough nutrients before the incision between the scion and the stock heals and can survive on its own; at least three buds increase the survival rate of the scion.

[0021] Furthermore, the cross sections of the rootstock and scion completely match when they are grafted, which increases the contact area between the rootstock and the scion and accelerates healing.

[0022] Furthermore, the seedbed uses red soil and river sand mixed evenly in a ratio of 1:1 or coconut bran as a matrix, providing a preferential culture matrix for the grafted rootstock, facilitating the growth of the rootstock root system and the intake of nutrients.

[0023] The advantages of the present invention are: 1. The cutting device can quickly and smoothly complete the cutting and separation operation of the fleshy rear end of the selected scion, thereby accelerating the early processing efficiency of the scion; 2. The cutting device adopts a simple structural design, has low manufacturing cost, simple maintenance, strong practicality, strong promotion, and is suitable for both indoor and outdoor use; 3. The operation of the splicing method is optimized and improved, especially in the processing of the rootstock and the scion, thereby accelerating the grafting speed and improving the grafting survival rate.

[0030] The present invention is described in detail below with reference to the accompanying drawings:

[0031] In the description of the present invention, it should be noted that the directions or positional relationships indicated by "left", "right", "front", "back", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore cannot be understood as a limitation on the present invention.

[0032] like Figure 1-5 As shown, a cutting device for pitaya grafting method includes a base 1, a scion placement rib 2, a slip ring 3, a sliding device 4, a cutting line 5, a ball head seat 6 and a rotating separation device 7. The base 1 is set up in a rectangular frame. The scion placement rib 2 is fixedly set on the upper surface of the base 1. The cross section of the scion placement rib 2 is triangular and is made of a soft material with a certain elasticity. This makes it convenient to place the scion and press it stably without squeezing and injuring the scion. The slip ring 3 is fixedly set at the right end of the base 1. The two are fixed by welding or screws, and a mutually limiting position is set between each other. The center of the slip ring 3 needs to be higher than the scion placement rib 2 when installed, so that the position of the wood fiber tube of the scion after placement is basically at the same position as the center of the slip ring 3, or near the center of the circle. The slip ring 3 is slidably provided with a sliding device 4, which can slide and rotate on the slip ring 3. The slip ring 3 is provided with a limiting edge for disengaging the sliding device 4. The cutting line 5 is made of a thin, soft steel wire. The thin steel wire can more conveniently and easily cut into the flesh of the scion, and the incision will be thinner and smoother. One end of the cutting line 5 is fixed on the inner side of the slip ring 3 through a ball head seat 6, specifically fixed at the highest point of the inner side. The other end of the cutting line 5 is fixed on the front end of the inner side of the sliding device 4 through the ball head seat 6. The fixed positions of the two ends of the cutting line 5 are on the same plane, which will not hinder the rotation of the sliding device 4 and the cutting surface will be smoother. In order to ensure that the cutting line 5 is too long and affects the cutting, the length of the cutting line 5 is equal to the diameter of the inner side of the slip ring 3. The length mentioned here is the effective length of the cutting line 5, excluding the length lost by the installation of both ends. In order to complete the cutting and separation of the flesh in one operation, a rotating separation device 7 is provided on the sliding device 4 for separating the cut flesh from the wood fiber tube.

[0033] The sliding device 4 includes a sliding seat 41 , a roller 42 and a handle 43 . The sliding seat 41 is slidably arranged on the slip ring 3 via the roller 42 . The sliding seat 41 is wrapped around the slip ring 3 in a U shape. The sliding seat 41 is provided with a handle 43 .

[0034] The rotational separation device 7 includes a connecting rod 71, a bearing 72, a roller 73, a separation rod 74, and a rotation lock 75. The connecting rod 71 is fixedly mounted on the sliding device 4, specifically at a rearward position inside the sliding device 4, i.e., at the end away from the ball head seat 6. A bearing 72 is fixedly mounted at the front end of the connecting rod 71. The bearing 72 is concentric with the slip ring 3 to ensure that the position of the bearing 72 does not shift when the sliding device 4 rotates. A roller 73 is rotatably mounted inside the bearing 72, with the bearing 72 protruding from both the front and rear ends of the roller 73. In front of the roller 73, there are three separating rods 74 arranged in a circular array. The separating rods 74 are distributed in an equilateral triangle, and one of the separating rods is relatively heavy. In this way, the heavier separating rod is always at the lowest point under normal circumstances. The distribution of the three separating rods can just avoid the triangular flesh of the scion placed on the scion placement ridge 2; the front end of the separating rod 74 is 0.5 cm away from the position where the dividing line 5 is installed, which avoids the cutting line 5 being blocked by the separating rod 74 during the cutting process; the rotating lock 75 is arranged on the connecting rod 71, and the rear end of the roller 73 is provided with a tooth groove 76 for use with the rotating lock 75. The rotating lock 75 includes a slider, a front top and a magnet. A slide groove for installing the slider is provided on the connecting rod 71, and a front top is provided at the front end of the slider. After exiting the slider, the front top will be stuck in the tooth groove 76 so that the roller 73 cannot rotate; magnets for positioning the slider are provided at both ends of the slide groove.

[0035] The principle of use of the cutting device in the present invention is: first place the scion away from the cutting line and push it forward to be fixed on the roller 73, rotate the sliding device 4 to make the cutting line 5 cut the flesh of the scion in a circular shape until it cuts the wood fiber tube, then push out the rotary locker 75 to lock the roller 73, and then rotate the sliding device 4 in the opposite direction to exit the cutting line 5. At the same time as exiting the cutting line 5, the separation rod 74 will rotate the cut and separated flesh to separate it from the wood fiber tube, and finally pick up the scion and remove the separated flesh.

[0036] A dragon fruit grafting method, such as Figure 6 As shown, the cutting device includes the following steps:

[0037] (1) Select a rootstock with a well-developed root system and strong growth. Use a cutting pair of scissors to cut the top horizontally, and then use a circular hollow tube to insert along the wood fiber tube to dig out a cylindrical hole; the front end of the circular hollow tube is provided with a straight or cross-shaped dividing piece. After insertion, the circular hollow tube can be rotated to separate the flesh inside the tube. After the circular hollow tube is removed, a cylindrical hole can be formed on the rootstock.

[0038] (2) Collect healthy branches that are mature in the current year, have full buds, and are free of quarantine diseases and insect pests from high-quality and high-yielding mother plants as scions. The length of the scion is 6.0 to 7.0 cm, and there are at least 3 buds on the scion. Place the scion on the cutting device, rotate the sliding device, and use the cutting line to cut the fleshy ring 1.5 cm at the rear end of the scion (the direction of scion growth is forward). Then, when withdrawing the line, lock the roller on the rotating separation device. During the withdrawal process, separate the cut fleshy flesh from the wood fiber tube, and finally remove the separated fleshy flesh.

[0039] (3) Use 75% alcohol to disinfect the incisions of the stock and scion, sterilize the incisions, and prevent the incisions from rotting and becoming diseased due to bacteria; after disinfection and drying, apply a layer of 20-30% aminoethyl hexanoate on the incisions. Aminoethyl hexanoate can promote the cell division and growth of the scion flesh and accelerate the healing of the incisions. Then, ventilate and let it stand for 15-20 minutes. The purpose of ventilation and standing is to dry the moisture of the applied aminoethyl hexanoate, and the cells near the incision absorb the aminoethyl hexanoate more comprehensively.

[0040] (4) Use a cotton swab to absorb the liquid in the cylindrical hole on the rootstock to avoid residual moisture in the hole and rotting from the inside. Then insert the wood fiber tube exposed at the rear end of the scion into the cylindrical hole on the rootstock. During grafting, the cross-section of the rootstock and scion should completely match. The selected scion should generally be smaller than the rootstock so that the scion can completely fit on the rootstock.

[0041] (5) Use sterilized transparent plastic film to fix the scion and wrap it tightly. The function of the transparent plastic film is to fix the scion and prevent external pathogens from entering the grafting incision.

[0042] (6) The grafted rootstock is placed on the seedbed for cultivation. The seedbed uses red soil and river sand mixed in a 1:1 ratio or coconut coir as the substrate. This base has good air permeability, strong water retention and drainage, which is convenient for the growth of the rootstock root system.

[0043] In the grafting method of the present invention, the stock and scion are good varieties with strong grafting affinity. The varieties with strong affinity will have a high success rate of grafting and the quality of the fruits produced will also be better. Before operation, the cutting knives such as the cutting knife, the circular hollow tube, and the cutting device need to be disinfected with 75% alcohol.

[0044] The grafting method of the present invention only describes the grafting process. As for the grafting time and temperature, seedbed treatment, temperature and humidity management of rootstock cultivation after grafting, fertilization management, pest and disease control, etc., the treatment is not much different from that of the prior art, so no further detailed discussion will be made here.

[0045] Although the above describes and illustrates the specific embodiments of the present invention in detail, it should be noted that various changes and modifications can be made to the above embodiments without departing from the spirit of the present invention and the scope of the appended claims.
