Description

Technical Field

[0001] The present invention relates to the technical field of antler mushroom production, specifically to a strain genetic improvement experimental platform and improvement method in the industrialized production of antler mushrooms. Background Art

[0002] Compared with other fungi with mature cultivation techniques, the mycelial growth rate of antler mushrooms is very slow, and the activity is poor. It is difficult to maintain the varietal characteristics, and the strains degenerate quickly, resulting in a low yield in the industrialized production of antler mushrooms and being difficult to meet the market demand. Therefore, it is necessary to optimize the production technology of antler mushrooms to increase the yield of antler mushrooms.

[0003] During the process of cultivating antler mushrooms, the staff needs to place the nutrients required for cultivating antler mushrooms in a test tube according to a ratio, and then shake it manually. During the shaking process, the nutrients in the test tube are fully mixed, and then the processed antler mushroom mycelia are placed in. The unmixed nutrients are unevenly distributed in the test tube, and the nutrient components required for mycelial growth are also unevenly distributed, which may affect the growth of the mycelia.

[0004] In addition, in order to increase the yield of antler mushrooms, the experimenters need to place multiple portions of antler mushroom mycelia at different environmental temperatures. Different experimental conditions facilitate the staff to confirm the optimal temperature conditions required for the growth of antler mushroom mycelia, thereby increasing the yield of antler mushrooms.

[0005] Therefore, we propose a strain genetic improvement experimental platform and improvement method in the industrialized production of antler mushrooms, which can quickly shake the nutrients in the test tube, test the effects of different proportions of nutrients on the growth of antler mushrooms, and test the growth conditions of antler mushroom mycelia at different temperatures, so as to solve the above problems.

[0054] Further Embodiments

[0055] The method for improving the strain legacy experimental platform in the above-mentioned factory production of Pleurotus eryngii comprises the following steps:

[0056] Step 1: Culture medium preparation:

[0057] Step 1.1: Get bran, poplar sawdust, bean dregs, yield increasing agent, superphosphate, humic acid and distilled water in proportion and mix them thoroughly;

[0058] Step 1.2: Put the mixture obtained in step 1.1 into the test tube 205, start the external motor to rotate the rotating shaft 106, and indirectly make the positioning block 109 shake the mixture in the test tube 205, and the culture medium is prepared;

[0059] Step 2: Test the environment required for growth:

[0060] Step 2.1: Adding an equal amount of Pleurotus eryngii mycelium into the test tube 205 processed in step 1;

[0061] Step 2.2: Injecting mixed gases of different proportions and types into different test tubes 205 in step 2.1;

[0062] Step 2.3: placing the mycelium treated in step 2.2 in an outdoor environment at different temperatures and maintaining the temperature constant, wherein the external environment temperature ranges between 20°C and 25°C;

[0063] Step 3: Observe the growth of velvet antler mushroom:

[0064] Step 3.1: Observe and record the growth conditions of the mycelium of Pleurotus eryngii in different test tubes 205 after the treatment in step 2 within 60 days.

[0065] In step S1.1, 25 parts of bran, 25 parts of poplar sawdust, 4 parts of bean dregs, 4 parts of yield increasing agent, 1 part of superphosphate, 1 part of humic acid, and 25 parts of distilled water are included.

[0066] In step S2.2, the gas injected into the test tube is selected from two or three of carbon dioxide, nitrogen, methane and oxygen.

[0067] The working process and principle of the overall content of the above embodiment are as follows:

[0068] First, nutrients with different ratios are separately put into different test tubes 205, and marks are made on the test tubes 205. Subsequently, the test tubes 205 are placed inside the positioning ring 202, and the positioning ring 202 fixes the positions of the test tubes 205.

[0069] Subsequently, the staff starts the external motor, and the rotating shaft 106 connected to the power output shaft of the external motor will rotate under the action of the external motor. At this time, the spiral groove 114 slidably connected to the outside of the rotating shaft 106 will move accordingly, prompting the slider 301 arranged inside the spiral groove 114 to spiral downward along the track of the spiral groove 114, and the driven ring 302 fixedly connected to the slider 301 will also move accordingly.

[0070] Since the rotating block 303 is rotatably connected to the outer wall of the driven ring 302, and the connecting rod 304 is fixedly connected to the outside of the rotating block 303, the rotating block 303 and the connecting rod 304 will move along with the driven ring 302. During the movement of the connecting rod 304, under the action of the moving track fixing rod 306 arranged inside it, it will move vertically downward, prompting the limiting ring 305 fixedly connected to the other end of the connecting rod 304 to move synchronously. At this time, the fixing block 307 arranged inside the limiting ring 305, the air pipe 308 arranged inside the fixing block 307, and the piston 309 connected to the air pipe 308 will move downward accordingly, and the piston 309 will move towards the test tube 205 until it is inserted into the test tube 205.

[0071] As the rotating shaft 106 rotates, the slider 301 will drive the driven ring 302 to gradually move to the end of the spiral groove 114. During this process, the piston 309 gradually inserted into the test tube 205 will drive the test tube 205 to move downward synchronously under the action of friction, so that the fixing ring 204 arranged outside the test tube 205, through the elastic connecting piece 203 and the positioning ring 202, prompts the placement platform 201 arranged outside the positioning ring 202 to move downward synchronously.

[0072] The movement of the placement platform 201 will cause the rotating shaft 106 connected to it to move downward. While compressing the telescopic rod 105, the rotating shaft 106 will gradually move towards the rotating part 104 until it meshes with the rotating part 104. During this process, the position of the test tube 205 will also decrease as the placement platform 201 descends. When the rotating shaft 106 meshes with the rotating part 104, the bottom of the test tube 205 will be embedded into the positioning block 109.

[0073] When the rotating shaft 106 and the rotating part 104 are in the meshing state, they will rotate synchronously under the action of the external motor. At this time, the wedge block 103 fixedly connected to the rotating part 104 will rotate accordingly, causing the extrusion part 107 that fits against the outer wall of the wedge block 103 to perform a reciprocating motion of approaching and separating from the wedge block 103 under the action of the wedge block 103. While the extrusion part 107 is moving, the positioning block 109 connected to the extrusion part 107 through the connecting rod 108 will also move accordingly. During the movement process, it will perform a reciprocating motion with an elliptical trajectory under the action of the cylindrical body 110 provided at the bottom of the connecting rod 108 and the elliptical groove provided on the limiting block 111.

[0074] At this time, the bottom of the test tube 205 clamped inside the positioning block 109 will move synchronously under the action of the positioning block 109. During this process, since a fixing ring 204 is provided on the outer side of the top of the test tube 205 and an elastic connecting piece 203 is provided on the outer side of the fixing ring 204, when the bottom of the test tube 205 rotates reciprocally, the top of the test tube 205 will also swing, making it evenly distributed inside the test tube 205. While avoiding manual shaking of multiple groups of test tubes 205, it can also quickly make the paired substances inside the test tube 205 fully mixed, so that the hyphae will not have problems in the growth process due to uneven distribution of nutrients, thus achieving the purpose of shaking the nutrients inside the test tube 205.

[0075] After the test tube 205 is shaken evenly, the external motor causes the rotating shaft 106 to rotate in the reverse direction. The rotating shaft 106 will cause the slider 301 to move in the reverse direction, and other structures will also move in the reverse direction according to the above steps, causing the piston 309 to disengage from the test tube 205.

[0076] Subsequently, the staff puts the antler mushroom hyphae into the test tube 205, and then starts the external motor again to make the rotating shaft 106 rotate forward. After moving according to the above movement process, the piston 309 will re-engage into the test tube 205. At this time, the rotating shaft 106 is notified to rotate.

[0077] Subsequently, the staff injects different types of gases into different test tubes 205 through the air pipe 308 to simulate the growth conditions of the antler mushroom hyphae in different gas environments. In different gas environments, the stress resistance of the antler mushroom hyphae can be tested, such as its growth requirements for gases such as carbon dioxide, nitrogen, methane, oxygen, etc., and its adaptability to the pH value, so as to ensure the repeatability and scientificity of the experiment.

[0078] During the test process, the constant temperature chamber 401 can also be adjusted to different temperatures to test the growth conditions of the antler mushroom hyphae under different temperature conditions, so as to determine the optimal temperature required for the growth of the antler mushroom hyphae.
