Description

Technical Field

[0001] The invention relates to the technical field of seedling cultivation, and in particular to a lycopodii seedling planting bed and a seedling cultivation method. Background Art

[0002] Because Baicao Rui has certain medicinal value, more and more farmers are planting it. In actual planting, most of them use greenhouses to grow seedlings, and transplant the well-cultivated seedlings.

[0003] Among them, when raising seedlings, the crop seeds are generally placed in a seedling bed, and nutrient solution is continuously and regularly added during the seedling raising process to ensure seed germination and normal growth of the seedlings.

[0004] Nowadays, when adding nutrient solution to seeds or seedlings on the nursery bed, direct spraying nursery beds or tidal nursery beds are generally used. Tidal nursery beds are more efficient and water-saving than direct spraying nursery beds. Since the roots of the seedlings in the tidal nursery beds are directly immersed in the nutrient solution, the formation of water film on the leaves of the seedlings is avoided, which interferes with the growth of the seedlings.

[0005] However, the existing tidal seedling bed mainly discharges the liquid in the seedling bed through the liquid inlet and the liquid outlet, and supplements the nutrition by soaking the roots of the seedlings in nutrient solution. Since the surface area of ​​the seedling bed is generally large, it takes a certain amount of time for the nutrient solution entering from the liquid inlet to completely cover the entire surface area of ​​the seedling bed. Therefore, compared with the area farther away from the liquid inlet, the area closer to the liquid inlet can contact with the nutrient solution in advance, while the time for the area farther away from the liquid inlet to contact the nutrient solution will lag behind the time for the area closer to the liquid inlet to contact the nutrient solution. The existence of the time difference can easily lead to different immersion times of the two areas in the nutrient solution, and the difference in immersion time of the nutrient solution will lead to different growth states of the seedlings, which in turn affects the entire seedling cultivation cycle.

[0006] At the same time, when the liquid outlet is discharging liquid, the flow velocity of the area closer to the liquid outlet is greater than the flow velocity of the area closer to the liquid outlet, which further accelerates the differentiation of the immersion time of each area.

[0007] In summary, the existing tidal seedling beds still have the problem that the seedlings in different areas of the seedling bed cannot be in synchronous and uniform contact with the nutrient solution, resulting in inconsistent immersion time for the seedlings in different areas. Inconsistent immersion time can easily lead to different growth states of the seedlings, thereby affecting the technical problem of the entire seedling cultivation cycle. Summary of the invention

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] like Figure 1-4 As shown, a lycopodii seedling bed comprises a bed body 1, the bed body 1 is a cylindrical structure, and a liquid outlet pipe 2 is arranged on the outer side wall of the bed body 1;

[0049] The surface of the bed body 1 is provided with a plurality of mounting grooves 3, and the plurality of mounting grooves 3 are evenly spaced and distributed on the surface of the bed body 1 in the form of multi-layer circular rings to form a multi-layer mounting network;

[0050] There are several culture pots 4, and one culture pot 4 is placed in each installation slot 3; wherein the culture pot 4 is a conventional pot structure for cultivating seedlings;

[0051] There are multiple annular pipes 5, each of which is buried in the inner cavity of the bed body 1 between two adjacent layers of mounting grooves 3. A number of drainage branch pipes 6 are evenly spaced on each annular pipe 5, and each drainage branch pipe 6 is connected to the surface of the bed body 1;

[0052] The annular enclosure plate 7 is installed outside the circumference of the bed body 1 to enclose the surface of the bed body 1 into a liquid storage chamber 8;

[0053] A nutrient solution adding device 9 is installed at the bottom of the bed 1, and the nutrient solution adding device 9 is connected to each annular tube 5 through a pipeline to simultaneously introduce the nutrient solution in each annular tube 5 into each culture pot 4;

[0054] The nutrient solution collecting device 10 is installed at the bottom of the bed 1, and the nutrient solution collecting device 10 is connected to the liquid outlet pipe 2 on the bed 1 to guide and collect the excess nutrient solution stored in the liquid storage chamber 8.

[0055] Among them, a pressure equalizing mechanism is arranged between the nutrient solution adding device 9 and the annular tube 5, and the pressure equalizing mechanism can synchronously discharge the nutrient solution from the drainage branch pipes 6 connected to each of the annular tubes 5, so that each area in the liquid storage chamber 8 can be synchronously covered with the nutrient solution.

[0056] The nutrient solution adding device 9 is a common tank structure with a control switch and a pressurizing device, which can release the liquid. The nutrient solution collecting device 10 is a common tank structure with a control switch, which can collect the liquid.

[0057] Since the annular tubes 5 are arranged in a concentric circle manner, that is, the annular tubes 5 are independently arranged, the nutrient solution in each annular tube 5 is added separately through the nutrient solution adding device 9, and the speed of spraying nutrient solution in each annular tube 5 is the same during the adding process, that is, the area covered by the sprayed nutrient solution in each annular tube 5 per unit time is the same.

[0058] Specifically, Figure 1-2 As shown, a pressure equalizing seat 11 is fixedly installed at the bottom center of the bed 1, and a spherical cavity 12 is opened in the inner cavity of the pressure equalizing seat 11, and the spherical cavity 12 is connected to the nutrient solution adding device 9 through a pipeline;

[0059] The same dimensional position in the spherical cavity 12 is connected to each annular tube 5 through a plurality of pipes respectively and correspondingly, and the distance between the connection between each pipe and the annular tube 5 and the two sides of the opening of the channel 13 is the same.

[0060] That is, the connection point between the pipeline and the annular tube 5 is located at the middle position of the annular tube 5, and the connection point can divide the annular tube into two parts, and the lengths of the two parts are the same.

[0061] In this way, it can be ensured that the pressure in each annular tube 5 is the same, and the amount of nutrient solution entering the annular tube 5 per unit time is the same.

[0062] After the nutrient solution enters the annular tube 5, it will flow along the length direction of the annular tube 5. Since the drainage branch pipes 6 are evenly distributed on the annular tube 5, the nutrient solution will flow from the drainage branch pipes 6. Although the time interval between the nutrient solution flowing out of each drainage branch pipe 6 is short, it will also interfere with the immersion time of the seedlings in the culture pots 4 on the side of the annular tube 5. In order to avoid such a phenomenon, it is necessary to ensure that each drainage branch pipe 6 can spray the same amount of nutrient solution at the same time.

[0063] Specifically, Figure 1-3 As shown, the side wall of one end of the drainage branch pipe 6 extending out of the surface of the bed body 1 is provided with a plurality of liquid outlets 19 connected with the internal flow channel of the drainage branch pipe 6, and the top of the inner cavity of the drainage branch pipe 6 is slidably inserted with a limiting column 14, and the end of the limiting column 14 away from the top of the drainage branch pipe 6 is connected to a sealing block 15, and a return spring 16 is connected between the sealing block 15 and the top of the drainage branch pipe 6;

[0064] When the reset spring 16 is in the initial state, the sealing block 15 just blocks the liquid outlet 19. When the nutrient solution in the annular tube 5 is continuously pressurized, when the pressure reaches a level that can push the reset spring 16 to deform, the limiting column 14 can drive the sealing block 15 to move upward, thereby exposing each liquid outlet tube 2. This ensures that each liquid outlet tube 2 can release the nutrient solution at the same time, thereby making the entire liquid storage chamber 8 evenly filled with the nutrient solution.

[0065] At the same time, when the annular pipe 5 is depressurized, the sealing block 15 is driven to return to its original position during the resetting process of the reset spring 16, that is, the sealing block 15 can close the liquid outlet pipe 2 in the water storage state, thereby reducing the entry of mud and sand into the drainage branch pipe 6 and reducing the possibility of pipeline blockage.

[0066] Since the installation groove 3 is embedded in the inner cavity of the bed body 1, a plurality of holes will be formed on the surface of the bed body 1. Due to the existence of the holes, a plurality of independent and unconnected water tanks will be formed. After the nutrient solution in the liquid storage chamber 8 is discharged through the liquid outlet 19, the nutrient solution stored in the water tank will soak the seedlings in the nursery, resulting in excess nutrient solution. Therefore, the nutrient solution in each installation groove 3 needs to be discharged.

[0067] Specifically, Figure 1-2 As shown, the surface of the bed body 1 is provided with a plurality of annular grooves 17 which are concentric with the bed body 1; an annular groove 17 is provided between each of two adjacent annular tubes 5;

[0068] A groove 13 is provided on the bed body 1 between two adjacent annular grooves 17. Each groove 13 can divide each corresponding annular tube 5 into a gap 20, and both ends of the gap 20 are closed; each annular groove 17 is connected to each installation groove 3 in each layer.

[0069] Since the annular groove 17 connects the various mounting grooves 3, the nutrient solution entering the various mounting grooves 3 flows along the annular groove 17, and the nutrient solution after flowing passes through the groove 13 and converges at the liquid outlet pipe 2. However, the flow speed of the annular groove 17 is slow during the flow process, and even some nutrient solution may remain in the annular groove 17. In order to avoid such a phenomenon, the shape of the annular groove 17 needs to be designed.

[0070] Specifically, Figure 1-2 As shown, the bottom depth of each annular groove 17 gradually increases along one end of the groove 13 toward the other end of the groove 13, so that the bottom of the annular groove 17 forms a structure with one end high and the other end low;

[0071] The lowest ends of the bottoms of the annular grooves 17 are located on the same diameter of the bed body 1 , and the grooves 13 are correspondingly connected to the lowest ends of the bottoms of the annular grooves 17 .

[0072] The bottom of the annular groove 17 is similar to a structure of a rotating slide. The nutrient solution flows due to its own gravitational potential energy and converges at the groove 18 when it flows to the lowest point, thereby reducing the residual nutrient solution in the annular groove 17 .

[0073] Further, such as Figure 1-2 As shown, the bottom depth of each annular groove 17 gradually increases along one end of the groove 13 toward the other end of the groove 13, so that the bottom of the annular groove 17 forms a structure with one end high and the other end low;

[0074] The lowest end of the bottom of the inner ring groove 17 and the highest end of the top of the outer ring groove 17 of the two adjacent ring grooves 17 are located on the same diameter of the bed body 1;

[0075] The lowest end of the bottom of the inner ring groove 17 and the highest end of the top of the outer ring groove 17 of the two adjacent ring grooves 17 are both connected through the groove 13;

[0076] In this way, the annular grooves 17 in each layer can be connected to a complete spiral decreasing structure, and a liquid flow mode similar to a vortex can be formed at the bottom of the bed body 1 during the liquid distribution process. The vortex can increase the flow of liquid in the annular groove 17, take away the sand in the annular groove 17, and avoid the accumulation of sand in the annular groove 17. After cleaning, the sand can be concentrated at the lowest end of the annular groove 17, so as to facilitate centralized treatment. On the other hand, the vortex can also take away the sand accumulated at the bottom of the bed body 1, thereby avoiding the possibility of blockage of the drainage branch pipe 6.

[0077] The sizes of the culture pots for raising seedlings of the spatholobi are different for the seedlings at different stages, and the culture pots are mainly fixed by the mounting grooves 3, so the mounting grooves 3 should also have various sizes.

[0078] Specifically, Figure 2As shown, the installation slot 3 includes a plurality of slots 18 of different diameters, each slot 18 is connected at the end, and the diameter of each slot 18 decreases gradually from the top to the bottom;

[0079] Each notch 18 is correspondingly connected to the annular groove 17 .

[0080] A method for raising seedlings of clematis is also provided, and the method steps are as follows:

[0081] S100, inserting the culture pots 4 into the mounting slots 3 one by one and fixing them;

[0082] S200, turning on the nutrient solution adding device 9, and adding nutrient solution into the annular tube through the pressure equalizing seat 11, until the nutrient solution can completely cover the surface of the bed 1;

[0083] S300, closing the nutrient solution adding device 9, and waiting for the liquid in the liquid storage chamber 8 to be stationary for a period of time until the seedlings in the culture pot 4 fully absorb the nutrient solution;

[0084] S400, opening the nutrient solution collecting device 10, discharging and collecting the liquid in the liquid storage chamber 8 through the liquid outlet pipe 2, and the nutrient solution collecting device 10 can also be re-introduced into the liquid storage chamber 8;

[0085] S500 , repeating steps S200 - S400 until the seedlings in the culture pots 4 grow normally, and taking out the culture pots 4 in each installation slot 3 for transplanting.

[0086] The device connects the seedlings in each culture pot with a concentric annular tube through a pressure equalizing seat, so that the seedlings in each culture pot are soaked in the nutrient solution in the same amount of time, thereby ensuring the consistency of the growth and development of each seedling and improving the quality of cultivation.
