[0002] Test tube inoculation for morel cultivation refers to the process of using test tubes as culture medium containers to inoculate morel strains into the culture medium in the test tubes for subsequent mycelial growth and reproduction. During the inoculation process, you first need to prepare sterile test tubes and culture media. Commonly used culture medium formulas may include potato boiled juice, glucose, agar, etc. These ingredients can provide the nutrients needed for the growth of morels. Then, pour the prepared culture medium into the test tubes, seal them with cotton plugs or silicone plugs, and perform high-temperature sterilization to kill the microorganisms therein.

[0003] In the prior art, when performing the morel inoculation operation, the operator generally holds the test tube in the left hand and inoculates above the flame of the alcohol lamp. Due to the instability of the hands during manual operation, it is difficult to ensure that the flame of the alcohol lamp can always tightly seal the mouth of the test tube. Continuous operation can easily cause hand shaking and cause the mouth of the test tube to leave the protection range of the flame, increasing the risk of contamination. At the same time, it may also cause safety hazards to the operator. Therefore, the existing test tube inoculation operation method has great challenges in terms of sterility and safety.

[0019] Example 1

[0020] refer to Figures 1 to 3 The test tube inoculation device for cultivating morels described in this embodiment includes a supporting base plate 1, a column 2 is fixedly connected to one side of the upper end of the supporting base plate 1, the height of the column 2 is 20 cm, and a cross column 3 is fixedly connected to the upper end of the column 2, and the cross column 3 is tilted, specifically tilted downward from left to right, so that the mouth of the test tube is close to the alcohol lamp. The length of the cross column 3 is about 13 cm, which is suitable for placing all common test tubes with a diameter of less than 25 mm. Support brackets 4 are fixedly connected on both sides of the cross column 3. The support bracket 4 is a U-shaped structure, and the semicircle diameter of the support bracket 4 is 25 mm. Side frames 7 are fixedly connected on both sides of the column 2, and the side frames 7 are also tilted, specifically tilted downward from left to right to prevent the rubber band 8 from slipping. The vertical column 2, horizontal column 3, bracket and side frame 7 are connected by welding. One side of the side frame 7 and the horizontal column 3 is connected with a rubber band 8. The rubber band 8 is common on the market, has good elasticity and durability, and reduces the cost of use. The test tube can be fixed by being tied to the side frame 7 and the horizontal column 3 to prevent shaking or displacement caused by external factors. A placement groove 11 is opened on one side of the vertical column 2 on the supporting base plate 1, and positioning components 12 are provided on both sides of the placement groove 11. Through the above arrangement, the left hand of the staff is freed, ensuring that the flame of the alcohol lamp on the inoculation rack can always seal the mouth of the test tube, reducing the risk of hand shaking and detaching from the flame, improving the success rate of inoculation, and ensuring the safety of the inoculation process.

[0021] refer to Figure 1 A rubber pad 5 is fixedly connected to the inner wall of the support bracket 4, and a convex strip 6 is fixedly connected to one side of the rubber pad 5, and a plurality of convex strips 6 are provided; by fixing the rubber pad 5 on the inner wall of the support bracket 4 and fixing the convex strips 6 made of rubber material on the rubber pad 5, the friction force of the contact surface between the test tube and the support bracket 4 can be increased, so that the test tube is not easy to slide after being placed on the support bracket 4, thereby providing a guarantee for the stable placement of the test tube.

[0022] refer to Figure 3 The outer surface of the side frame 7 is provided with anti-slip grooves 9, one side of the rubber band 8 is in contact with the anti-slip grooves 9, one end of the side frame 7 is fixedly connected to a limiting block 10, and one side of the limiting block 10 is an arc-shaped surface; by providing the anti-slip grooves 9, the friction force of the contact surface between the rubber band 8 and the side frame 7 can be increased to prevent the rubber band 8 from sliding on the side frame 7, and by providing the limiting block 10, the rubber band 8 is limited when sliding on the side frame 7 to prevent the rubber band 8 from jumping out of the side frame 7.

[0023] refer to Figure 1The positioning assembly 12 includes a screw 123, which is threadedly connected to both sides of the placement groove 11, one end of the screw 123 is fixedly connected to an adjustment block 124, and the other end of the screw 123 is rotatably connected to a positioning plate 121 through a bearing 122, and the positioning plate 121 is slidably connected to the inside of the placement groove 11, and a protrusion 125 is fixedly connected to the outer surface of the adjustment block 124, and both sides of the placement groove 11 are fixedly connected to a screw sleeve 126, and the screw 123 is threadedly connected to the screw sleeve 126; by setting Positioning assembly 12, after the alcohol lamp base is placed on the placement groove 11, rotate the adjustment block 124, and the adjustment block 124 drives the screw 123 to rotate. Since the positioning plate 121 is connected to the screw 123 through the bearing 122, the screw 123 can drive the positioning plate 121 to move horizontally, so that the alcohol lamp can be fixed in the placement groove 11, which is conducive to the flame generated by the burning alcohol lamp to be aligned with the test tube mouth. By fixing the screw sleeve 126 on both sides of the placement groove 11, it is convenient for the screw 123 to be threaded on the placement groove 11.

[0024] Principle and advantages of use: Pour the prepared culture medium into the test tube, seal it with a cotton plug or a silicone plug, and then place it on the support bracket 4 to prevent the test tube from moving forward and backward. The rubber pad 5 and the convex strip 6 on the inner wall of the support bracket 4 can increase the friction force to prevent the test tube from sliding left and right. Then one side of the rubber band 8 passes through the limit block 10 and enters the side frame 7, and the other side passes through the support bracket 4 to contact the test tube, so that the test tube can be pressed on the support bracket 4 to prevent the test tube from sliding horizontally. The alcohol lamp is placed in the placement groove 11, and the rotating drive block drives the screw 123 to rotate on the screw sleeve 126, so that the screw 123 pushes the positioning plate 121 to move through the bearing 122. The two positioning plates 121 slide in the placement groove 11 to clamp and fix the base of the alcohol lamp to prevent the alcohol lamp from shaking and ensure that the flame is stably aligned with the test tube mouth, thereby freeing the staff's left hand and ensuring that the flame of the alcohol lamp on the inoculation rack can always seal the test tube mouth, reducing the risk of hand shaking and detaching from the flame, improving the inoculation success rate, and ensuring the safety of the inoculation process.
