Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a rock-planting cultivation greenhouse. Background Technology

[0002] Greenhouses provide crops with a stable and suitable growing environment, allowing them to reach their full potential and improving yield and quality. Greenhouses isolate crops from the influence of external climate, providing a continuous and stable environment. This extends the growing season and increases planting opportunities. By controlling environmental factors such as light, temperature, and humidity, greenhouses promote crop growth and development, thereby increasing yield.

[0003] The existing irrigation technologies in greenhouses mainly consist of furrow irrigation and subsurface irrigation. Fertilization is mostly carried out by flushing with water and furrow or hole application, which is time-consuming, labor-intensive, and inefficient. Uneven irrigation and fertilization lead to significant waste of water and fertilizer, resulting in low utilization rates. Continuous planting leads to the accumulation of chemical fertilizer residues, and the salt concentration in the surface soil can be more than twice that of open fields, damaging the soil structure and causing soil salinization. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a rock-planted cultivation greenhouse, which solves the issues of significant soil-borne diseases, large water and fertilizer losses, and severe salinity in traditional soil cultivation. It enables year-round continuous planting and production, improving crop growth rate, quality, and annual yield.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A rock-planting cultivation greenhouse includes a greenhouse body and a nutrient solution tank. Cultivation areas are respectively set on both sides of the bottom of the greenhouse body. Multiple planting troughs are set at intervals in the cultivation areas. Planting rocks are set at the bottom of the planting troughs, and the opening of the planting troughs is covered with a planting board. The planting board is provided with through planting holes.

[0007] The side of the planting board facing away from the planting trough is provided with a nutrient solution sub-pipe, and the side of the nutrient solution sub-pipe facing the planting board is provided with a through drainage hole. Each nutrient solution sub-pipe in the cultivation area is connected to the nutrient solution tank through a nutrient solution main pipe, and the nutrient solution main pipe is equipped with a drainage pump, which is controlled by a controller.

[0008] A collection pool is provided at one end of the planting trough. The opening height of the collection pool is aligned with the height of the planting rock so that the nutrient solution overflowing from the planting rock can enter the collection pool. The collection pool is equipped with a discharge pipe.

[0009] Furthermore, the discharge pipe of the cultivation area is connected to the nutrient solution tank through a recovery main pipe, and the recovery main pipe is equipped with a water pump; the water pump is electrically connected to the controller.

[0010] Furthermore, the collection pools of the two cultivation areas are arranged opposite each other, and the ground of the cultivation area is provided with a sloping slope. The sloping slope is arranged along both sides of the shed to the middle, so that the middle of the shed ground is lower than the sides of the shed ground.

[0011] Furthermore, a nutrient solution concentration sensor is installed in the nutrient solution tank. The nutrient solution tank is equipped with a nutrient solution replenishment pipe and a water replenishment pipe. One end of the nutrient solution replenishment pipe is electrically connected to the nutrient solution tank, and the other end is connected to the nutrient solution stock storage tank. The nutrient solution replenishment pipe is also equipped with a first switching valve. One end of the water replenishment pipe is electrically connected to the nutrient solution tank, and the other end is connected to the water supply end. The water replenishment pipe is also equipped with a second switching valve. The nutrient solution concentration sensor, the first switching valve, and the second switching valve are electrically connected to the controller.

[0012] Furthermore, the nutrient solution tank is equipped with a stirring mechanism, which includes a stirring shaft and a stirring motor. At least two stirring shafts are provided. One end of the stirring shaft is located inside the nutrient solution tank and is fixedly equipped with stirring blades. The other end is rotatably connected to the top of the nutrient solution tank and extends out of the nutrient solution tank. The stirring motor is fixedly installed on the top of the nutrient solution tank and is used to drive the stirring shafts.

[0013] Furthermore, each of the planting troughs is equipped with a soil sensor, and a second switch valve is provided at one end of the nutrient solution sub-pipe near the main nutrient solution pipe. The soil sensor and the second switch valve are electrically connected to the controller.

[0014] Furthermore, the top of the shed is evenly spaced with spray pipes, each spray pipe having atomizing holes. All the spray pipes are connected through a main spray pipe, which is connected to a water supply end.

[0015] The beneficial effects of this utility model are:

[0016] 1. Using planting rock, such as perlite, as the cultivation medium allows for better oxygen absorption by crop roots, reducing the risk of root rot. It also eliminates the habitat for many soil-borne pests and diseases, significantly reducing pesticide use and pest infestations. This results in greener, safer produce that meets consumer demand for high-quality agricultural products. A drainage pump pumps the nutrient solution from the nutrient solution tank through the main pipe to the sub-pipes, where it drains through the drain holes. This ensures the nutrient solution provides essential nutrients for crop growth in each planting trough. A collection pool collects any overflowing nutrient solution from the planting rock for reuse. This solves the problems of traditional soil cultivation, such as significant soil-borne diseases, high water and fertilizer loss, and severe substrate salinization. It enables continuous year-round planting, improving crop growth rate, quality, and annual yield.

[0017] 2. The nutrient solution discharged from the main pipe is collected into the nutrient solution tank by a water pump, thus realizing continuous recycling and reuse of the nutrient solution and improving its reuse efficiency. A nutrient solution concentration sensor can obtain the nutrient solution concentration in the tank in real time. Based on the data from the sensor, the controller controls the opening and closing of the first and second switching valves to inject water and nutrient solution concentrate into the tank, ensuring the nutrient solution is at the required concentration. This guarantees that crops receive the appropriate nutrients, and eliminates the need for manual mixing, reducing labor intensity and enabling barrier-free crop rotation. Attached Figure Description

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0027] Please also see Figures 1 to 5 A preferred embodiment of the rock-planting cultivation greenhouse of this utility model includes a greenhouse body 1 and a nutrient solution tank 2.

[0028] Cultivation areas are set on both sides of the bottom of the shed 1. Multiple planting troughs 3 are set at intervals in the cultivation areas. Planting rocks 301 are set at the bottom of the planting troughs 3, and planting boards 31 are set on the openings of the planting troughs 3. Planting boards 31 are provided with through planting holes 311.

[0029] A nutrient solution sub-pipe 4 is provided on the side of the planting board 31 facing away from the planting trough 3. A through-hole 401 is provided on the side of the nutrient solution sub-pipe 4 facing the planting board 31. Each nutrient solution sub-pipe 4 in the cultivation area is connected to the nutrient solution tank 2 via a main nutrient solution pipe 41. The main nutrient solution pipe 41 is equipped with a drainage pump 42, which is controlled by a controller 6. In this embodiment, the nutrient solution is prepared using organic biogas slurry, amino acids, and trace mineral elements.

[0030] like Figure 1 and 2 As shown, a collection pool 32 is provided at one end of the planting trough 3. The opening height of the collection pool 32 is aligned with the height of the planting rock 301 so that the nutrient solution overflowing from the planting rock 301 can enter the collection pool 32. The collection pool 32 is provided with a discharge pipe 5.

[0031] Using planting rock as a cultivation medium, such as perlite, allows crop roots to breathe more oxygen, making them less prone to root rot. It also deprives many soil-borne pests and diseases of their habitat, significantly reducing pesticide use and pest and disease occurrence. The resulting agricultural products are greener and safer, meeting consumers' demand for high-quality agricultural products.

[0032] Under the action of the drainage pump 42, the nutrient solution in the nutrient solution tank 2 is discharged into the nutrient solution sub-pipe 4 through the nutrient solution main pipe 41 and then discharged through the drain hole 401, so that the nutrient solution can supplement the nutrients needed for crop growth in each planting trough 3. At the same time, by setting up the collection tank 32, the nutrient solution overflowing from the planting rock 301 can enter the collection tank 32 for collection and reuse, which can solve the problems of large water and fertilizer loss in traditional soil cultivation and serious salinity in substrate cultivation, and improve the crop growth rate.

[0033] like Figure 1 and 2 As shown, the discharge pipe 5 of the cultivation area is connected to the nutrient solution tank 2 via a main recovery pipe 51, and the main recovery pipe 51 is equipped with a water pump 52; the water pump 52 is electrically connected to a controller 6, which is a PLC controller. The nutrient solution discharged from the discharge pipe 5 is collected into the nutrient solution tank 2 by the water pump 52 through the main recovery pipe 51, thereby realizing the continuous circulation and reuse of the nutrient solution and improving the reuse efficiency of the nutrient solution.

[0034] The collection pools 32 of the two cultivation areas are set opposite each other. The ground of the cultivation area is provided with a sloping slope, which is set along both sides of the shed 1 towards the middle, so that the middle of the ground of the shed 1 is lower than the sides. Under the action of the sloping slope, the nutrient solution in the planting trough 3 can flow into the collection pool 32 more quickly under the action of gravity, which improves the return speed of the nutrient solution and further avoids the problem of severe salting.

[0035] like Figure 1 and Figure 3 As shown, a nutrient solution concentration sensor 21 is installed in the nutrient solution tank 2. The nutrient solution tank 2 is equipped with a nutrient solution replenishment pipe 22 and a water replenishment pipe 23. One end of the nutrient solution replenishment pipe 22 is electrically connected to the nutrient solution tank 2, and the other end is connected to the nutrient solution stock storage tank. The nutrient solution replenishment pipe 22 is equipped with a first switch valve 221. One end of the water replenishment pipe 23 is electrically connected to the nutrient solution tank 2, and the other end is connected to the water supply end. The water replenishment pipe 23 is equipped with a second switch valve 231. The nutrient solution concentration sensor 21, the first switch valve 221, and the second switch valve 231 are electrically connected to the controller 6.

[0036] Under the action of nutrient solution concentration sensor 21, the concentration of nutrient solution in nutrient solution tank 2 can be obtained in real time. Based on the data of nutrient solution concentration sensor 21, controller 6 controls the opening and closing of first switch valve 221 and second switch valve 231, which can inject water and nutrient solution stock solution into nutrient solution tank 2, so that the nutrient solution in nutrient solution tank 2 can be at the required concentration, ensuring that crops can obtain suitable nutrients. Moreover, it is not necessary to manually adjust the solution, reducing labor intensity and realizing barrier-free crop rotation planting production.

[0037] like Figure 3 As shown, the nutrient solution tank 2 is equipped with a stirring mechanism, which includes a stirring shaft 7 and a stirring motor 71. At least two stirring shafts 7 are provided. One end of the stirring shaft 7 is located inside the nutrient solution tank 2 and is fixedly equipped with stirring blades 701. The other end is rotatably connected to the top of the nutrient solution tank 2 and extends out of the nutrient solution tank 2. The stirring motor 71 is fixedly installed on the top of the nutrient solution tank 2 and is used to drive the stirring shaft 7. In this embodiment, the stirring motor 71 is electrically connected to the controller 6.

[0038] In this embodiment, a cover plate 24 is provided on the top of the nutrient solution tank 2. The two sides of the cover plate 24 are connected to the nutrient solution tank 2 by bolts to seal the opening of the nutrient solution tank 2. The stirring shaft 7 is rotatably connected to the cover plate 24, and a first synchronous pulley 721 is provided at one end of the cover plate 24 that protrudes outside the nutrient solution tank 2. The stirring motor 71 is fixedly mounted on the cover plate 24, and the stirring motor 71 is equipped with a reducer. The output of the reducer is provided with a second synchronous pulley 722. The first synchronous pulley 721 is connected to the second synchronous pulley 722 through a synchronous belt 723. The synchronous belt 723, the first synchronous pulley 721, and the second synchronous pulley 722 form a triangular structure to drive the stirring shaft 7, so that the stirring blades 701 can stir the nutrient solution in the nutrient solution tank 2, ensuring that the nutrient solution concentration is the same at all positions in the nutrient solution tank 2, thereby providing the crops with the required nutrients.

[0039] In this embodiment, each planting trough 3 is equipped with a soil sensor 33, and a third switching valve 43 is installed at the end of the nutrient solution sub-pipe 4 near the main nutrient solution pipe 41. The soil sensor 33 and the third switching valve 43 are electrically connected to the controller. The soil sensor 33 in this embodiment includes a soil moisture sensor, a soil temperature sensor, a nitrogen, phosphorus, and potassium sensor, and a pH sensor. The soil sensor 33 monitors the data in the planting rock 301, and at the same time, the third switching valve 43 is controlled to individually replenish the nutrient solution in each planting trough 3, thereby achieving precision cultivation.

[0040] like Figure 4 As shown, sprinkler pipes 8 are evenly spaced on the top of the greenhouse 1. Each sprinkler pipe 8 has an atomizing hole 801. All sprinkler pipes 8 are connected by a main sprinkler pipe 81, which is connected to a water supply. In this embodiment, the main sprinkler pipe 81 is equipped with a water pump. By controlling the water pump to start, water in the main sprinkler pipe 81 can enter the sprinkler pipes 8 and then be discharged through the atomizing holes 801, thereby reducing the temperature inside the greenhouse 1 and replenishing moisture for the crops.

[0041] Preferably, a lighting device for brightness control can be installed inside the greenhouse 1 to provide the crops with suitable light duration and intensity.

[0042] The rock-planting greenhouse in this embodiment uses perlite as a substrate and recycles nutrient solution, solving problems such as high water and fertilizer loss in traditional soil cultivation, root rot in hydroponics, heavy salinity in general substrate cultivation, and high energy consumption in aeroponics. It also eliminates the habitat of many soil-borne pests and diseases, significantly reducing pesticide use and producing greener, safer agricultural products that meet consumer demand for high-quality produce.

[0043] This embodiment creates optimal growing conditions for crops, enabling rapid growth and allowing for uninterrupted, barrier-free, factory-style crop rotation. Leafy vegetables can be planted more than 8 times a year, and fruit cucumbers can be planted 6 times a year, with an annual yield of 40,000-60,000 jin per mu.

[0044] This embodiment is adaptable to various planting scenarios, breaking through the limitations of traditional soil planting. It can be used for planting in barren areas and even on non-traditional farmland such as abandoned shrimp ponds. For example, a rock-planting high-efficiency smart agriculture industry demonstration project has been successfully developed in abandoned shrimp ponds in Shaluoliao Village, Guangpo Town, Gangkou District, Fangchenggang City. Another example is the rock-planting high-efficiency smart agriculture production base in the Dashishan area of ​​Tiandeng Town, Tiandeng County, Chongzuo City, which has changed the previous situation of difficulty in developing industries in the Dashishan area.
