Description

Technical Field

[0001] The utility model relates to the technical field of plant maintenance, in particular to a culture dish for plant grafting. Background Art

[0002] Plant grafting is a horticultural technique that involves attaching a part of one plant (usually a branch or bud) to another, allowing them to grow together and form a new plant. Grafting can be done by branch grafting or bud grafting. Grafting utilizes the ability of plants to heal after injury.

[0003] In plant biology experiments, it is sometimes necessary to conduct grafting experiments on seedlings of herbaceous plants, such as Arabidopsis thaliana and rapeseed. However, in the existing technology, there are limited dedicated instruments for plant grafting, and most of them are completed directly on the plant rootstock or covered with ordinary transparent glass covers for experiments. As a result, the grafting process lacks suitable auxiliary props, leaving room for improvement. Utility Model Content

[0004] The utility model aims to solve the above-mentioned technical problem of lack of suitable auxiliary props in the process of herbaceous plant grafting, and provides a culture dish for plant grafting.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is as follows: a culture dish for plant grafting, comprising an inner box, an outer box, and a cover plate; the inner box and the outer box are both provided with openings;

[0006] The inner box can be placed in the outer box, the inner depth of the outer box is greater than the height of the inner box, and a sealing ring is provided at the upper end of the inner box, the inner side of the sealing ring contacts the inner box;

[0007] A base is provided at the lower end of the inner box, and the upper end surface of the base is arc-shaped; a grille plate is provided vertically inside the inner box and higher than the base, and the grille plate is located at the middle end of the inner box;

[0008] The outer side surface of the inner box is provided with a plurality of circular grooves, and the circular grooves all pass through the inner box.

[0009] Furthermore, the cover plate can cover the opening of the outer box, and a limiting ring capable of entering the inner box is provided on one side of the cover plate, and the limiting ring is fixedly connected to the cover plate.

[0010] Furthermore, the inner box, outer box, and cover plate limiting ring are all made of transparent glass.

[0011] Furthermore, the end of the base is located at two-thirds of the bottom surface of the inner box.

[0012] Furthermore, the circular grooves are all arranged on the outer side surface of the inner box near the upper end; and the inner diameters of the circular grooves gradually decrease from the outside to the inside.

[0013] The advantages of this utility model compared with the prior art are:

[0014] It has a double-layer structure. When water or nutrient solution or other agents that are beneficial to the healing of the stock incision are injected into the cavity in the double-layer structure, the mixed liquid can evaporate naturally and slowly evaporate into the inner box through the circular groove, thereby maintaining the moisture in the inner box and evaporating and penetrating the agent, which is beneficial to the growth and development of the stock and scion.

[0015] In addition to being placed vertically for grafting culture, it can also be placed sideways for breeding on the grid plate. The corresponding culture medium can be placed under the grid plate to provide nutrients for the seed roots. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will be described in further detail below with reference to the accompanying drawings.

[0021] Example 1, combined with the attached Figure 1 A culture dish for plant grafting, comprising an inner box 1, an outer box 2, and a cover plate 3; both the inner box 1 and the outer box 2 are provided with openings; the dish has two usage modes: the opening is upward for grafting culture; the opening is to one side for breeding culture, and the dish is suitable for laboratories and has strong practicality;

[0022] Combined with attachment Figure 2 The cover plate 3 can cover the opening of the outer box 2. A limiting ring 4 that can enter the inner box 1 is provided on one side of the cover plate 3. The limiting ring 4 is fixedly connected to the cover plate 3 so that the cover plate 3 can completely cover the inner box 1 and the outer box 2, preventing external moisture from entering during cultivation, protecting the seedlings and the grafted parts, and preventing mold or rooting;

[0023] The inner box 1, outer box 2, cover plate 3 and limit ring 4 are all made of transparent glass, which is convenient for observation and recording during laboratory use;

[0024] Combined with attachment Figure 2, the inner box 1 can be placed in the outer box 2, the inner depth of the outer box 2 is greater than the height of the inner box 1, the inner box 1 and the outer box 2 enclose a cavity, thereby forming a double-layer structure, which has better heat preservation and is less affected by the external environment temperature, making it easier for the rootstock and scion to heal and grow;

[0025] Combined with attachment Figure 2 、 3 , a base 6 is provided at the lower end of the inner box 1, and the upper end surface of the base 6 is arc-shaped; the end of the base 6 is located at two-thirds of the bottom surface of the inner box 1, so that when used vertically, there is a distance between the upper end of the base 6 and the upper end of the inner box 1. During grafting and cultivation, the herbaceous plant body is placed on the culture medium, and the part below the base 6 can be used to place the culture medium, and the part above the base 6 is used for the growth of the grafted part, so as to avoid the grafted part from contacting the culture medium, thereby avoiding the scion from growing roots and affecting the grafting; in addition, the provision of the base 6 reduces the internal space in the inner box 1, saving the amount of culture medium used; in addition, when used vertically, the arc-shaped surface of the base 6 reduces the amount of culture medium used as the height increases, so that the culture medium at the upper end is light in weight and not easy to collapse after long-term use, thereby avoiding the grafted part from contacting the culture medium or being buried when collapsing.

[0026] Combined with attachment Figure 2 , a grid plate 7 is vertically provided inside the inner box 1 and higher than the base 6, and the grid plate 7 is located at the middle end of the inner box 1; when used horizontally, the grid plate 7 can be used to lay culture soil for breeding experiments, and the culture medium is placed under the grid plate 7 so that the roots of the seeds enter the culture medium, forming a closed, moist and warm environment as a whole, which can improve the breeding survival rate; it is worth mentioning that when used vertically, since the grid plate 7 is also in the same direction, it will not affect the placement of herbaceous plants and the normal operation of stock and scion;

[0027] Combined with attachment Figure 2 , a sealing ring 5 is provided at the upper end of the outer box 2, and the inner side of the sealing ring 5 is in contact with the inner box 1; a plurality of circular grooves 8 are arranged on the outer side of the inner box 1, and the circular grooves 8 all penetrate the inner box 1; the circular grooves 8 are all arranged at the outer side of the inner box 1 near the upper end; the inner diameter of the circular grooves 8 gradually decreases from the outside to the inside; during the grafting experiment, water or nutrient solution and other experimental reagents are added to the outer box 2, such as growth agents such as gibberellins that can promote the healing of the grafted part. Under the action of the double-layer structure insulation, the mixed liquid will slowly evaporate and enter the inner box 1 through the circular grooves 8, which is convenient for the healing and growth of the grafted part. It should be noted that the liquid level needs to be lower than the circular grooves 8 of the lowest layer to avoid direct injection of the mixed liquid; when used for breeding, adding water to the cavity between the inner box 1 and the outer box 2 can maintain a suitable temperature in the inner box 1 and avoid some experimental species from losing activity due to increased temperature.
