[0041] Adopting the above technical solution, the present invention has the following beneficial effects: Fill the nutrient soil into the cultivation pot and plant a suitable rootstock in the nutrient soil. Generally, a Ligustrum plant with strong growth, developed roots, and a straight trunk is selected as the rootstock. Its height and thickness should be determined according to the expected height of the tall stem and the size of the scion. Then, select excellent Ligustrum lucidum branches or buds as the scion. The scion should be ensured to be healthy, free from pests and diseases, and have a certain number of plump buds. Graft the scion to the appropriate position of the rootstock, usually on the upper part of the main trunk or side branches of the rootstock. After grafting, set the lifting ring and the support ring on the rootstock, and connect the support frame to the lifting module. The lifting module can drive the lifting ring and the support ring to move synchronously by driving the support frame to move downward, which is convenient for inserting the watering component and the humidity sensor into the soil around the rootstock. Use the humidity sensor to monitor the humidity of the soil in real time. If the soil humidity is low, the watering component starts to work for watering. During the watering process, the lifting module can drive the lifting ring and the support ring to move upward. The lifting ring can adjust the working positions of the watering component and the humidity sensor by rotating on the support frame, which is convenient for uniformly wetting the soil around the rootstock and improving the watering effect. When the humidity monitored by the humidity sensor reaches the predetermined value, the watering component stops working. At the same time, the control component can loosen the soil during the watering process by driving the watering component to rotate on the support ring. Loosening the soil can improve the soil structure. The soil particle structure after loosening becomes loose, forming a good capillary system, which helps the water to uniformly penetrate into the entire root zone. Moreover, the loose soil can better retain water and reduce the evaporation loss of water. For example, in the non-loosened substrate, a large amount of water may evaporate within 1-2 days after watering; after loosening the soil, under the same conditions, the water can be retained in the soil for 3-4 days, providing a more lasting water supply for the Ligustrum lucidum grafted seedlings. Loosening the soil can also make the fertilizer better contact with the soil particles, promote the decomposition and release of the fertilizer, and at the same time, it is also convenient for the roots to contact and absorb the fertilizer ions, which is beneficial to improving the quality of the seedlings. Compared with the prior art, the present invention avoids the problems that the existing seedling raising methods often can only perform simple spraying operations based on experience, cannot accurately control the environmental parameters, are prone to large environmental fluctuations, and cause problems such as diseases caused by excessive humidity or excessive drought of the grafted seedlings, which greatly affect the success rate of seedling raising and the quality of the seedlings through the coordinated setting of the precise watering mechanism and the humidity sensor.

[0058] The present invention will be further explained and illustrated below in combination with specific implementation manners.

[0059] Please refer to Figures 1 - 11, a high-stem grafting seedling-raising device for Ligustrum lucidum var. vicaryi provided by an embodiment of the present invention, the high-stem grafting seedling-raising device for Ligustrum lucidum var. vicaryi comprising:

[0060] a base 1 and a cultivation pot 2 arranged on the base 1, wherein a plurality of water drainage holes 14 are formed in the bottom of the cultivation pot 2;

[0061] a precise irrigation mechanism, the precise irrigation mechanism comprising a lifting ring 5, a support ring 11, a support frame 6 and an irrigation assembly, a lifting module for placing the support frame 6 and driving the support frame 6 to move up and down is arranged in the cultivation pot 2, the lifting ring 5 is rotatably installed on the support frame 6, a plurality of groups of irrigation assemblies are arranged on the support ring 11, and an electric telescopic rod 27 for controlling the working state of the irrigation assembly is further arranged between the support ring 11 and the lifting ring 5, and a control assembly for driving the irrigation assembly to rotate during irrigation is further arranged on the support ring 11;

[0062] and a humidity sensor 13 for detecting soil humidity, at least one group of the humidity sensors 13 is arranged at the bottom of the support ring 11.

[0063] In an embodiment of the present invention, the device can be placed in an existing cultivation chamber. Fill the nutrient soil into the cultivation pot 2 and plant a suitable rootstock in the nutrient soil. Generally, a Ligustrum plant with strong growth, developed roots, and a straight trunk is selected as the rootstock. Its height and thickness are determined according to the expected height of the tall stem and the size of the scion. For example, if you want to cultivate a Ligustrum lucidum 'Brilliant' with a 2 - 3 - meter tall stem, a rootstock with a height of about 1.5 - 2 meters and a diameter of 3 - 5 centimeters may be selected. Then, select excellent Ligustrum lucidum 'Brilliant' branches or buds as the scion. The scion should be ensured to be healthy, free from pests and diseases, and have a certain number of plump buds. Graft the scion to an appropriate position on the rootstock, usually on the upper part of the main trunk or lateral branches of the rootstock. After grafting, slip the lifting ring 5 and the support ring 11 onto the rootstock, and connect the support frame 6 to the lifting module. The lifting module can drive the lifting ring 5 and the support ring 11 to move synchronously by driving the support frame 6 to move downward, facilitating the insertion of the irrigation component and the humidity sensor 13 into the soil around the rootstock. The humidity sensor 13 is used to monitor the humidity of the soil in real - time. If the soil humidity is low, the irrigation component starts to work for irrigation. During the irrigation process, the lifting module can drive the lifting ring 5 and the support ring 11 to move upward. The lifting ring 5 can adjust the working positions of the irrigation component and the humidity sensor 13 by rotating on the support frame 6, facilitating the uniform wetting of the soil around the rootstock and improving the irrigation effect. When the humidity monitored by the humidity sensor 13 reaches the predetermined value, the irrigation component stops working. At the same time, the control component can loosen the soil during the irrigation process by driving the irrigation component to rotate on the support ring 11. Loosening the soil can improve the soil structure. After loosening, the soil particle structure becomes loose, forming a good capillary system, which helps the water to uniformly penetrate into the entire root zone. Moreover, the loose soil can better retain water and reduce the evaporation loss of water. For example, in the non - loosened substrate, a large amount of water may evaporate within 1 - 2 days after watering; while after loosening, under the same conditions, the water can be retained in the soil for 3 - 4 days, providing a more lasting water supply for the grafted Ligustrum lucidum 'Brilliant' seedlings. Loosening the soil can also make the fertilizer better contact with the soil particles, promote the decomposition and release of the fertilizer, and at the same time, facilitate the contact and absorption of the root system with the fertilizer ions, which is beneficial to improving the quality of the seedlings. Compared with the prior art, through the coordinated setting of the precise irrigation mechanism and the humidity sensor 13, the present invention avoids the problems of the existing seedling - raising methods that often can only perform simple spraying operations based on experience, cannot accurately control the environmental parameters, easily cause excessive environmental fluctuations, and make the grafted seedlings suffer from diseases caused by too high or too dry humidity, greatly affecting the success rate of seedling - raising and the quality of the seedlings.

[0064] In one embodiment of the present invention, please refer to Figures 1 - 11, a external gear ring 25 is fixedly installed at the bottom of the lifting ring 5, and a first gear 26 meshing with the external gear ring 25 is rotatably installed on the support frame 6.

[0069] In this embodiment, the first motor can drive the external gear ring 25 to rotate by driving the first gear 26 to rotate. The external gear ring 25 can drive the lifting ring 5 to rotate forward or backward, so as to realize the adjustment of the working position of the watering assembly. The rotation angle of the lifting ring 5 can be controlled according to the number of watering assemblies, so as to avoid the watering assembly still being inserted into the original position after the lifting ring 5 rotates. If there are four groups of watering assemblies, the rotation angle of the lifting ring 5 each time is not more than 90 degrees, and the preferred range is 40-60 degrees;

[0070] The lifting plate 8 can be used to fix and support the support frame 6. The second motor can drive the threaded rod 10 to rotate, and the lifting plate 8 can drive the support frame 6 to move up and down. In the initial state, the lifting plate 8 is at the highest position, which is convenient for installing the support frame 6.

[0082] And a blocking rod 39 for blocking the watering pipe 29, one end of the blocking rod 39 is fixedly connected to the inside of the guide pipe 34, and the other end of the blocking rod 39 is slidably matched with the watering pipe 29;

[0083] The water inlet hole 38 is of a horn-shaped structure, and the opening size of the water inlet hole 38 on the side facing the water guide pipe 19 is larger than the opening size of the water inlet hole 38 on the side facing the base 1;

[0084] The water supply mechanism includes:

[0085] A first water guide ring 4 rotatably installed on the outer wall of the cultivation pot 2, and the side surface of the first water guide ring 4 is of an open structure;

[0086] A side enclosure plate 17 rotatably installed on the side surface of the first water guide ring 4, and a sealed cavity is formed between the side enclosure plate 17 and the first water guide ring 4;

[0089] and a main pipeline 3, which is communicated with the second conduit 18 through a tee joint;

[0091] The bottom of the soil loosening pipe 15 is of a conical structure, which is convenient for the soil loosening pipe 15 to be inserted into the soil;

[0092] The control assembly includes:

[0093] A second water guide ring 30 rotatably installed on one of the soil loosening pipes 15, and a through hole communicating with the second water guide ring 30 is formed in the soil loosening pipe 15;

[0094] A support shaft 31 fixedly installed on the support ring 11, a control box 21 is rotatably installed on the support shaft 31, and the control box 21 is communicated with the second water guide ring 30 through a third conduit 20;

[0095] A piston plate 43 slidably installed in the control box 21, and a second return spring 42 for elastically pressing the piston plate 43 is further arranged in the control box 21;

[0096] A push-pull rod 22 slidably installed in the control box 21, one end of the push-pull rod 22 is fixedly connected to the piston plate 43, and the other end of the push-pull rod 22 is rotatably connected to the internal gear ring 24 through a connecting shaft 23.

[0097] In this embodiment, after the soil loosening pipe 15 is inserted into the soil, the height of the lifting ring 5 and the support ring 11 can be adjusted so that part of the irrigation part is located on the soil surface, realizing irrigation at different positions. Specifically: the main pipeline 3 facilitates water supply to multiple groups of devices at the same time. The second conduit 18 can introduce water into the first water guide ring 4. Through the cooperation of the first conduit 12 and the socket 16, water can be introduced into the cavity of the lifting ring 5. Finally, the lifting ring 5 enters the water guide pipe 19. In the initial state, the blocking block 37 completely blocks the water inlet hole 38. When irrigation is required, the electric telescopic rod 27 starts to work, increasing the distance between the lifting ring 5 and the support ring 11, so that the relative sliding occurs between the water guide pipe 19 and the soil loosening pipe 15. The linkage frame 36 will drive the blocking block 37 to move away from the water inlet hole 38, creating a gap between the blocking block 37 and the water inlet hole 38. As a result, the water in the water guide pipe 19 can enter the soil loosening pipe 15 through the water inlet hole 38. The water will enter the water guide cavity 33 through the blocking plate 32. The fourth conduit 35 can introduce water into the guide pipe 34, thereby pushing the irrigation pipe 29 to move, making the irrigation pipe 29 insert into the soil. After the blocking rod 39 is separated from the irrigation pipe 29, the water in the guide pipe 34 will enter the irrigation pipe 29 and flow out through the irrigation holes 40, realizing the irrigation function. And part of the water will enter the control box 21 through the second water guide ring 30 and the third conduit 20, thereby pushing the piston plate 43 to move. The piston plate 43 can drive the push rod 22 to move. Through the cooperation of the push rod 22 and the connecting shaft 23, the internal gear ring 24 can be driven to rotate at a small angle. The internal gear ring 24 can drive the second gear 28 to rotate. The second gear 28 realizes the soil loosening function by driving the soil loosening pipe 15 to rotate and cooperating with the outwardly protruding irrigation pipe 29. By intermittently adjusting the distance between the lifting ring 5 and the support ring 11, the electric telescopic rod 27 can make the blocking block 37 intermittently block the water inlet hole 38, enabling water to intermittently enter the control box 21 and the guide pipe 34. And in cooperation with the second return spring 42 and the first return spring 41, the push rod 22 can reciprocally slide in the control box 21 (which can realize the reciprocating forward and reverse rotation of the internal gear ring 24, the second gear 28, and the soil loosening pipe 15). The irrigation pipe 29 reciprocally slides in the guide pipe 34, improving the soil loosening effect. The irrigation part located on the soil surface can spray water onto the soil surface, thereby improving the irrigation effect. By driving the irrigation pipe 29 to rotate at a small angle, the soil loosening pipe 15 can avoid affecting the root system while achieving the purpose of soil loosening, thereby improving the breeding quality.

[0098] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention.
