Description

Technical Field

[0001] This invention relates to the field of vegetable seedling cultivation technology, specifically to a vegetable seedling cultivation device and method based on sponge blocks and hydroponic facilities. Background Technology

[0002] With the development of society, the application of hydroponics for vegetables has become more and more widespread. Hydroponic vegetables refer to vegetables that are grown with most of their roots growing in a nutrient solution layer, and are provided with water, nutrients and oxygen only by the nutrient solution. This is different from the traditional soil cultivation method. Hydroponic vegetables have a short growth cycle and are rich in a variety of vitamins and minerals that are essential to the human body.

[0003] Chinese Patent CN101263777A discloses a method for hydroponic cultivation of vegetable seedlings using a sponge-like substrate. This method utilizes a sponge-based hydroponic seedling facility in conjunction with a specialized seedling nutrient solution, enabling year-round hydroponic production of vegetable seedlings. The growth process eliminates the need for traditional seedling substrates, overcoming the drawbacks of traditional plug seedlings being susceptible to the physicochemical properties of the substrate and unsuitable for hydroponic vegetable cultivation. The seedlings cultivated under this patent receive their necessary nutrients through a specialized nutrient solution, resulting in uniform seedling growth, no slow-release period, short seedling cycle, and a high rate of robust seedlings.

[0004] In actual use, the seedling facilities described in the above patents have a simple structure, limited functionality, and a single adjustment method in the actual cultivation environment. Summary of the Invention

[0005] The purpose of this invention is to provide a vegetable seedling cultivation device and method based on sponge blocks and hydroponic facilities, which solves the problems mentioned in the background art that the seedling cultivation facilities have a simple structure, few functions, and a single adjustment method in actual cultivation environment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vegetable seedling cultivation device based on sponge blocks and hydroponic facilities, comprising a hydroponic seedling box, a fixed partition, and a nutrient solution storage tank. The fixed partition is installed below the hydroponic seedling box, a lifting frame is installed above the fixed partition, three auxiliary cultivation plates are installed above the lifting frame, a sponge cultivation block is installed inside the fixed partition, and a cultivation port for vegetable seedling cultivation is provided inside the sponge cultivation block. The nutrient solution storage tank is located below the sponge cultivation block.

[0007] Preferably, the hydroponic seedling box has an integrally formed sliding groove inside, the lifting frame is slidably connected to the hydroponic seedling box through the sliding groove, and an air pressure valve is installed at the lower end of the hydroponic seedling box to adjust the air pressure inside the sliding groove.

[0008] Preferably, both ends of the auxiliary cultivation plate are welded to connecting plates, and the connecting plates are connected to the lifting frame by fixing bolts. The auxiliary cultivation plate is used to adjust the root and stem angle of the vegetable seedlings.

[0009] Preferably, a squeezing block is installed at the lower end of the auxiliary culture plate. The squeezing block is connected to the auxiliary culture plate by fixing screws, and a fixing pressure plate is welded to the lower end face of the squeezing block. The fixing pressure plate is used to squeeze the water out of the sponge culture block.

[0010] Preferably, lifting cylinders are installed on both sides of the fixed partition, and connecting lifting blocks are welded to the outside of the lifting frame. The two ends of the lifting cylinders are fixedly connected to the connecting lifting blocks and the fixed partition, respectively.

[0011] Preferably, the fixed partition is connected to the nutrient solution storage tank by fixing screws, the sponge culture block is embedded inside the fixed partition and sealed to the fixed partition, the fixed partition is provided with an integrally formed liquid guiding channel inside, and a diverter is provided between the liquid guiding channel and the sponge culture block.

[0012] Preferably, the lower end of the culture port is provided with a nutrient solution inlet, and the lower end of the nutrient solution inlet is provided with a diversion channel, and the diversion head is connected to the diversion channel and the liquid guiding channel respectively.

[0013] Preferably, the nutrient solution storage tank has a circulation pipe running through it, the middle of the circulation pipe is connected to the liquid guiding channel, and a circulation pump is installed at both ends of the circulation pipe. The circulation pump is used to draw nutrient solution into the liquid guiding channel, and a filter element is installed inside the nutrient solution storage tank.

[0014] The cultivation method for vegetable seedling cultivation devices based on sponge blocks and hydroponic facilities includes the following steps:

[0015] Step 1: Place the sponge culture block inside the upper part of the fixed partition, and put the vegetable seedling seeds to be planted into the culture port;

[0016] Step 2: Introduce nutrient solution into the circulation pipe through the circulation pump. The circulation pipe then feeds the nutrient solution into the liquid delivery channel, which is then transferred to the sponge culture block through the diversion head and diversion channel to ensure full contact with the vegetable seedlings and seeds.

[0017] Step 3: Adjust the length of the telescopic lifting cylinder and the position of the lifting frame. The lifting frame will move the auxiliary cultivation plate, the squeezing block and the fixed pressure plate up and down. The auxiliary cultivation plate will keep the vegetable seedlings in the correct growing position. The fixed pressure plate will press the sponge cultivation block to squeeze the water from the side of the sponge cultivation block into the vicinity of the vegetable seedlings to carry out the cultivation work.

[0018] Step 4: Use a circulation pump to draw water from inside the hydroponic seedling box into the nutrient solution storage tank, and use the circulation pipe and filter cartridge to circulate and filter the nutrient solution for reuse.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention, during use, introduces nutrient solution into the circulation pipe via a circulation pump. The circulation pipe then inputs the nutrient solution into the liquid guiding channel, which is then transmitted to the sponge culture block through the diverter and diverter channel, ensuring full contact with the vegetable seedlings. The length of the telescopic lifting cylinder is adjustable for easy operation. Adjusting the position of the lifting frame causes the auxiliary cultivation plate, the squeezing block, and the fixed pressure plate to rise and fall. The auxiliary cultivation plate maintains the growth position of the vegetable seedlings, while the fixed pressure plate presses down on the sponge culture block, squeezing the water from the side of the sponge culture block into the vicinity of the vegetable seedlings for cultivation. This invention is adaptable to different types of cultivation, provides good cultivation results, facilitates continuous cultivation, and has good functionality, adapting to different types of vegetable seedlings.

[0021] 2. The cultivation facility of the present invention uses a combination of sponge culture blocks and hydroponic seedling boxes to introduce nutrient solution for cultivation. A circulation pump draws water from inside the hydroponic seedling box into the nutrient solution storage tank. The nutrient solution is then circulated and filtered using circulation pipes and filter cartridges, allowing for reuse. This saves on nutrient solution consumption, improves environmental protection, and facilitates long-term use. Attached Figure Description
