Description

Technical Field

[0001] This utility model relates to the field of seedling technology, and in particular to a floating seedling bed. Background Technology

[0002] Floating seedling cultivation is a method of raising seedlings by filling seedling trays with substrate and floating them in a nutrient solution in a seedling pool. Strong seedlings are cultivated by controlling the mineral nutrients in the nutrient solution and the temperature and humidity conditions within the seedling shed. Floating seedling cultivation requires a high degree of flatness at the bottom of the seedling pool to ensure the nutrient solution level is within acceptable limits during seedling growth. Furthermore, the height of the nutrient solution is also important during seedling growth. To help the seedlings adapt to the post-transplanting environment, alternating wet and dry conditions are necessary. Before transplanting, seedlings need to be hardened off to improve their adaptability. There are two main types of methods for alternating wet and dry conditions or hardening off: the first involves draining the nutrient solution from the bottom of the seedling pool, and the second involves using tools or devices to lift the seedling trays so that their bottoms are completely removed from the seedling pool. Common methods of the first type include: 1. Pumping the nutrient solution from seedling pool A into seedling pool B, thus removing the seedlings from pool A; then pumping the nutrient solution from pool B into seedling pool A, thus removing the seedlings from pool B. This process is repeated to achieve alternating wet and dry conditions or hardening off. However, this method carries the risk of cross-infection of pathogens. 2. A water storage tank connected to the seedling pond is installed to pump the nutrient solution from the seedling pond into the water storage tank, so that the seedlings in the seedling pond can be separated from the nutrient solution. However, this method also carries the risk of cross-contamination of the nutrient solution. The second method is to place a seedling tray support at the bottom of the seedling pond. The lifting mechanism repeatedly lifts and lowers the seedling tray with the seedling tray support. This method has high requirements for the strength of the support, corrosion resistance and the lifting mechanism, and has the problem of high cost. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a floating seedbed to solve the technical problems mentioned in the background art.

[0004] The objective of this utility model is achieved through the following technical solution: A floating seedbed includes a seedling pool, a seedling tray, and a water storage container. One or more hollow rectangular floats are placed in the seedling pool, and the seedling trays are placed on the floats. One or more inlet and outlet ports are provided on the floats, and pipes and water pumps are connected between the inlet and outlet ports and the water storage container.

[0005] Furthermore, protrusions are evenly distributed on the surface of the float.

[0006] Furthermore, a partition is provided inside the float, which divides the float into two or more water storage chambers, and each water storage chamber is provided with an inlet and outlet.

[0007] Furthermore, the two or more water storage chambers are divided into two rows, and the two rows of water storage chambers are evenly spaced along the length of the seedling pond.

[0008] Furthermore, the pipeline includes two main pipes, a first branch pipe, and a second branch pipe. Water pumps for pumping water and draining water are respectively installed on the two main pipes. One end of the main pipe is connected to a water storage container, and the other end is connected to the first branch pipe via a tee. The first branch pipe is connected to the water storage chamber through multiple second branch pipes. Valves are provided on the second branch pipes.

[0009] Furthermore, the number of the first branch pipes is two, located on both sides of the length direction of the float.

[0010] Furthermore, the density of the pipe is less than the density of the nutrient solution.

[0011] The beneficial effects of this utility model are: The floating seedling bed proposed in this utility model involves placing a hollow rectangular float in a seedling pond, and placing seedling trays on the float. The float has inlet and outlet ports connected to a water storage container via pipes and a water pump. When water is pumped into the float through the pipes and pump until a certain level is reached, the float sinks, and the seedling trays float on the surface of the nutrient solution, achieving contact between the seedling trays and the nutrient solution. After the water is drained from the float through the pipes and pump, the float rises, floating on the surface of the nutrient solution and supporting the seedling trays. This allows the seedling roots to detach from the nutrient solution, achieving alternating wet and dry conditions or hardening off the seedlings.

[0012] The surface of the floating block is evenly covered with protrusions. When the floating block floats up and lifts the seedling tray, it can ventilate the bottom of the seedling tray and improve the effect of alternating between dry and wet conditions or hardening off the seedlings.

[0013] A partition is installed inside the float block, which divides the float block into two or more water storage chambers. Each water storage chamber has an inlet and outlet. In this way, when the number of seedling trays above the float block is inconsistent, the float block can be leveled by adjusting the amount of liquid in the water storage chamber.

[0014] Meanwhile, this floating seedbed also has the following beneficial effects: 1. The nutrient solution in the seedling pool will not mix with the nutrient solution in other seedling pools, which can reduce the risk of cross-infection of pathogens; 2. The solution in the water storage container, pipes, water pump and water storage chamber is clean water and will not mix into the seedling pool, further reducing the probability of pollution; 3. The float is processed in the factory and has a high surface levelness. Placing the seedling tray on it can reduce the requirement for the flatness of the bottom of the seedling pool.

[0015] Other advantages, objectives, and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination and study, or may be learned from practice of this invention. The objectives and other advantages of this invention can be realized and obtained through the following description. Attached Figure Description

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0023] Example 1 like Figure 1-2 The floating seedbed shown includes a seedling pool 2, a seedling tray 3, and a water storage container (not shown in the figure). A hollow rectangular float is placed in the seedling pool 2, and the seedling tray 3 is placed on the float 1. The surface of the float 1 is evenly provided with protrusions, and an inlet and outlet is provided on the float 1. A pipe 7 and a water pump (not shown in the figure) are connected between the inlet and outlet and the water storage container. The density of the pipe is less than the density of the nutrient solution, so the pipe can also float in the nutrient solution.

[0024] The beneficial effects of this utility model are: The floating seedbed proposed in this invention uses hollow rectangular floats placed in a seedling tray. Seedling trays are placed on the floats, and inlet and outlet ports are provided on the floats. These ports are connected to a water storage container via pipes and a water pump. When water is pumped into the floats through the pipes and pump until a certain level is reached, the floats sink, and the seedling trays float on the surface of the nutrient solution, achieving contact between the trays and the solution. After the water is pumped out, the floats rise again, supporting the seedling trays and detaching the seedling roots from the nutrient solution, thus achieving alternating wet and dry conditions or hardening off. Evenly distributed protrusions on the surface of the floats allow for ventilation at the bottom of the trays after the floats rise and support the seedling trays, further enhancing the alternating wet and dry conditions or hardening off.

[0025] Meanwhile, this floating seedbed also has the following beneficial effects: 1. The nutrient solution in the seedling pool will not mix with the nutrient solution in other seedling pools, which can reduce the risk of cross-infection of pathogens; 2. The solution in the water storage container, pipes, water pump and water storage chamber is clean water and will not mix into the seedling pool, further reducing the probability of pollution; 3. The float is processed in the factory and has a high surface levelness. Placing the seedling tray on it can reduce the requirement for the flatness of the bottom of the seedling pool.

[0026] Example 2 Based on Example 1, such as Figure 3-4 As shown, a vertical partition is provided inside the float 1, dividing the float 1 into two or more water storage chambers 4. Each water storage chamber 4 has an inlet and outlet. The two or more water storage chambers 4 are divided into two rows, and the two rows of water storage chambers 4 are evenly spaced along the length of the seedling pond 2. The pipeline includes two main pipes, two first branch pipes 5, and two second branch pipes 6 (the main pipes are not shown in the figure). The two first branch pipes 5 are located on both sides of the length of the float 1. Water pumps for pumping water and draining water are respectively installed on the two main pipes. One end of the main pipe is connected to the water storage container, and the other end is connected to the first branch pipe 5 after being merged into one through a tee. The first branch pipe 5 on each side of the float is connected to the water storage chamber 4 on that side through multiple second branch pipes 6. Valves (not shown in the figure) are provided on the second branch pipes 6.

[0027] A partition is installed inside the float block, which divides the float block into two or more water storage chambers. Each water storage chamber has an inlet and outlet. In this way, when the number of seedling trays above the float block is inconsistent, the float block can be leveled by adjusting the amount of liquid in the water storage chamber.

[0028] Example 3 The difference from Example 1 is as follows: Figure 5 As shown, the floating seedbed includes two or more floating blocks 1, which work together to support all the seedling trays 3 in the seedling pool 2. Such floating blocks are small in size, making them easy to manufacture and transport.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
