Description

Technical Field

[0001] This utility model relates to the field of plant cultivation technology, specifically to a water and fertilizer storage and aeration structure for plant cultivation. Background Technology

[0002] With the development of science and technology, the application of plant cultivation technology is becoming wider and wider. Many crops, forest trees, fruit trees, flowers, medicinal plants, and ornamental plants can be cultivated in containers. The containers used for plant cultivation generally have a drainage hole at the bottom. During cultivation, the plant is placed directly in the container, and then soil or cultivation substrate is filled into the container. The roots of the plant are directly buried in the soil or cultivation substrate. This type of container has poor air permeability, which is not conducive to plant growth. Utility Model Content

[0003] This invention proposes a water and fertilizer storage and aeration structure for plant cultivation, which solves the problem of poor aeration of containers in related technologies, which is detrimental to plant growth.

[0004] The technical solution of this utility model is as follows: a water and fertilizer storage and air-permeable structure for plant cultivation, including a cultivation bucket, the key point being: the air-permeable structure also includes a first connecting pipe, a second connecting pipe, and an air-permeable box set inside the cultivation bucket and buried in the soil or cultivation substrate, with air-permeable holes opened on the air-permeable box, and the first connecting pipe and the second connecting pipe are both connected at one end to the inside of the air-permeable box and at the other end to the outside of the cultivation bucket.

[0005] The first connecting pipe is set horizontally, and the second connecting pipe is set vertically, with the lower end face of the second connecting pipe located above the first connecting pipe; or, both the first and second connecting pipes are set horizontally, with the second connecting pipe located above the first connecting pipe.

[0006] The breathable structure also includes a retaining net covering the outside of the breathable box. Through holes are opened on the retaining net at positions corresponding to the first connecting pipe and the second connecting pipe. The area of ​​the mesh of the retaining net is smaller than the area of ​​the breathable holes.

[0007] The connection point between the first connecting pipe and the vent box is located above the center line of the height direction of the vent box. The cavity below the first connecting pipe inside the vent box is the liquid storage cavity, and the cavity above the liquid storage cavity is the vent box.

[0008] The first connecting pipe is located at 2 / 3 of the height of the vent box.

[0009] The horizontally positioned second connecting pipe is located at 5 / 6 of the height of the vent box.

[0010] The number of breathable boxes is at least two. The width of the top of the breathable box is 18-25cm and the width of the bottom is 25-30cm. The distance between the tops of two adjacent breathable boxes is less than or equal to 20cm. Two to five breathable boxes form a breathable box group. One breathable box in the same breathable box group is connected to both the first connecting pipe and the second connecting pipe. The other breathable boxes are connected to the second connecting pipe. Adjacent breathable boxes are connected by a horizontal pipe, which is flush with the first connecting pipe.

[0011] The breathable structure also includes a water-absorbing layer at the bottom of the cultivation bucket, a water tank at the bottom of the cultivation bucket, and a water-absorbing strip whose upper end is connected to the water-absorbing layer and whose lower end passes through a hole opened on the bottom plate of the cultivation bucket and extends to the bottom of the water tank below the liquid surface. A gap is left between the upper surface of the water tank and the bottom plate of the cultivation bucket.

[0012] The working principle and beneficial effects of this utility model are as follows: A breathable box is buried in the soil or cultivation substrate inside the cultivation bucket, and a breathable hole is opened on the breathable box. One end of the first connecting pipe and the second connecting pipe are connected to the inside of the breathable box, and the other end is connected to the outside of the cultivation bucket. When the first connecting pipe is set horizontally and the second connecting pipe is set vertically, the lower end face of the second connecting pipe is located above the first connecting pipe. When both the first connecting pipe and the second connecting pipe are set horizontally, the second connecting pipe is located above the first connecting pipe.

[0013] During cultivation, when watering with nutrient solution, the solution can be poured into the cultivation container through the second connecting pipe, or it can be poured directly into the plant at the opening of the container, allowing the solution to seep into the ventilation box below. When the nutrient solution reaches the opening of the first connecting pipe, excess solution flows out of the container, stopping the pouring and positioning the first connecting pipe above the solution surface. The first and second connecting pipes work together to create air convection within the ventilation box, ensuring fresh air. This air can permeate through the surrounding soil or substrate, supplying oxygen to the plant roots. This oxygen supply method provides more oxygen to the roots than well-aerated soil, improving the permeability of the surrounding soil or substrate, meeting the oxygen requirements of the roots, promoting plant growth, and offering a simple and convenient design. Long-term trials have shown that plants grow better using this breathable structure than those grown in well-aerated fertile soil, with superior growth, yield, and product quality compared to field-grown plants.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Specific embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the plant cultivation water and fertilizer storage and aeration structure includes a cultivation bucket 1, a first connecting pipe 2, a second connecting pipe 3, and an aeration box 5 set inside the cultivation bucket 1 and buried in the soil or cultivation substrate 4. Aeration holes 6 are opened on the aeration box 5. The first connecting pipe 2 and the second connecting pipe 3 are connected to the inside of the aeration box 5 at one end and to the outside of the cultivation bucket 1 at the other end.

[0026] There are two ways to set up the first connecting pipe 2 and the second connecting pipe 3. The first way is that the first connecting pipe 2 is set horizontally, and the second connecting pipe 3 is set vertically, with the lower end face of the second connecting pipe 3 located above the first connecting pipe 2. For example... Figure 1 , Figure 2 and Figure 3 As shown; the second type is where both the first connecting pipe 2 and the second connecting pipe 3 are horizontally arranged, with the second connecting pipe 3 located above the first connecting pipe 2, as shown. Figure 4 As shown. Regardless of the method used, the key is to ensure air convection within the ventilation box 5. The advantage of vertically positioning the second connecting pipe 3 is that it facilitates watering or nutrient solution application. The advantage of horizontally positioning both the first connecting pipe 2 and the second connecting pipe 3 is that there are no obstructions inside the cultivation container 1, making operation convenient.

[0027] The ventilation box 5 is located at the bottom of the cultivation container 1. The outer surface of the ventilation box 5 is soil or cultivation substrate. The height of the ventilation box 5 is equal to half the height of the cultivation container 1. During cultivation, when watering or nutrient solution is applied, it can be poured into the cultivation container 1 through the second connecting pipe 3, or water or nutrient solution can be directly poured into the plant at the opening of the cultivation container 1, allowing the water or nutrient solution to seep into the ventilation box 5 at the bottom of the cultivation container 1. When the water or nutrient solution reaches the opening of the first connecting pipe 2, the excess water or nutrient solution will flow out of the cultivation container 1 through the first connecting pipe 2, stopping the pouring of water or nutrient solution into the cultivation container 1, and placing the first connecting pipe 2 above the liquid surface. The first connecting pipe 2 and the second connecting pipe 3 work together to achieve air convection within the ventilation box 5, ensuring fresh air inside. Air inside the ventilation box 5 can flow out through the ventilation holes 6, permeating the soil or cultivation substrate 4 outside the ventilation box 5 to supply oxygen to the plant roots. This oxygen supply method provides more oxygen to the plant roots than well-aerated soil, improving the permeability of the soil or cultivation substrate 4 surrounding the plant and meeting the oxygen requirements of the plant roots. The capillary action of the soil or cultivation substrate 4 surrounding the ventilation box 5 transports nutrient solution upwards to the plant roots, meeting the plant's needs for water and nutrients. This promotes plant growth, has a simple structure, and is easy to use. Long-term trials have shown that plants using this ventilation structure grow better than those in well-aerated fertile soil, exhibiting superior growth, yield, and product quality compared to field-grown plants. When the ventilated box 5 is filled with nutrient solution, it can be managed as a soilless cultivation method. It provides sufficient nutrition, does not burn the seedlings, and stores fertilizer in the nutrient solution, which can fully meet the nutritional needs of plant growth.

[0028] To further improve air permeability, the end of the first connecting pipe 2 located outside the cultivation container 1 can be connected to an air bladder or other inflatable component. By squeezing the air bladder or using the inflatable component, gas can be added to the air permeable box 5, increasing the air pressure inside the air permeable box 5. Alternatively, an air extraction component can be connected to the second connecting pipe 3 to extract the gas from the air permeable box 5, allowing new gas to enter the air permeable box 5 through the first connecting pipe 2, thus achieving rapid gas circulation and renewal.

[0029] As a further improvement to this utility model, the breathable structure also includes a retaining net 7 covering the periphery of the breathable box 5. Through holes are provided on the retaining net 7 at positions corresponding to the first connecting pipe 2 and the second connecting pipe 3. The mesh area of ​​the retaining net 7 is smaller than the area of ​​the breathable holes 6. For example... Figure 1 , Figure 2 and Figure 4 As shown, the retaining net 7 can prevent the surrounding soil or cultivation substrate 4 from entering the air box 5, and at the same time prevent the air holes 6 from being blocked by soil or cultivation substrate 4, thus affecting the air permeability.

[0030] As a further improvement to this utility model, the connection point between the first connecting pipe 2 and the ventilation box 5 is located above the center line of the ventilation box 5 in the height direction. The cavity below the first connecting pipe 2 inside the ventilation box 5 is a liquid storage cavity, and the cavity above the liquid storage cavity is a ventilation cavity. Preferably, the first connecting pipe 2 is located at 2 / 3 of the height of the ventilation box 5. This ensures that the lower 2 / 3 of the ventilation box 5 contains water or nutrient solution, and the upper part contains air, resulting in sufficient air storage to meet the plant's aeration needs, and sufficient water or nutrient solution storage to avoid frequent watering or nutrient solution application.

[0031] As a further improvement to this utility model, the horizontally arranged second connecting pipe 3 is located at 5 / 6 of the height of the vent box 5, so that there is a sufficiently large gap between the second connecting pipe 3 and the first connecting pipe 2, preventing water or nutrient solution from entering the second connecting pipe 3.

[0032] As a further improvement to this utility model, such as Figure 5 and Figure 6 As shown, when the cultivation container 1 is large, one aeration box 5 cannot meet the usage requirements. At least two aeration boxes 5 are needed. Gas from multiple aeration boxes 5 can supply oxygen to the plant roots through the surrounding soil or cultivation substrate 4, better meeting the plant's aeration needs. The aeration boxes 5 should not be too large, otherwise the area around the center of the top of the aeration box 5 will be relatively dry. Therefore, the width of the top of the aeration box 5 is 18-25cm, and the width of the bottom is 25-30cm. The distance between the tops of two adjacent aeration boxes 5 is less than or equal to 20cm. Two to five aeration boxes 5 form an aeration box group. One aeration box 5 in the same group is connected to both the first connecting pipe 2 and the second connecting pipe 3, while the remaining aeration boxes 5 are connected to the second connecting pipe 3. Adjacent aeration boxes 5 are connected by a horizontal pipe 8, which is flush with the first connecting pipe 2. The height of the aeration box 5 is 25-35cm, preferably 30cm.

[0033] As a further improvement to this utility model, the breathable structure also includes a water-absorbing layer 9 disposed at the bottom of the cultivation bucket 1, a water tank 10 disposed below the cultivation bucket 1, and a water-absorbing strip 11 whose upper end is connected to the water-absorbing layer 9 and whose lower end passes through a through hole opened in the bottom plate of the cultivation bucket 1 and extends to below the liquid surface in the water tank 10. A gap is left between the upper surface of the water tank 10 and the bottom plate of the cultivation bucket 1. Figure 7 As shown, the water in the water tank 10 can enter the cultivation container 1 under the absorption of the water-absorbing strip 11 and the water-absorbing layer 9, achieving the purpose of automatic water replenishment, and at the same time, it can also provide ventilation for the cultivation container 1. The water-absorbing layer 9 is preferably a layered structure made of cotton cloth, and the water-absorbing strip 11 is preferably a strip structure made of cotton cloth.

[0034] like Figure 5 and Figure 6 As shown, when watering or nutrient solution, first pour water into the ventilated box 5 connected only to the second connecting pipe 3, and finally pour water into the ventilated box 5 connected to both the first connecting pipe 2 and the second connecting pipe 3. Some water or nutrient solution will seep into the surrounding soil or cultivation substrate 4, and excess water or nutrient solution will be stored in the ventilated box 5. When the liquid level in the ventilated box 5 reaches the horizontal pipe 8, as water or nutrient solution continues to be added, water or nutrient solution will enter the adjacent ventilated box 5 through the horizontal pipe 8 until water or nutrient solution flows out of the cultivation bucket 1 through the first connecting pipe 2. At this point, stop pouring water or nutrient solution and ensure that the first connecting pipe 2 is above the liquid level.

[0035] Multiple cultivation containers 1 can also be arranged horizontally in sequence. The ventilation box 5 inside the first cultivation container 1 is connected to a water pump 13 via a water inlet pipe 12. The water pump 13 is connected to a water storage tank 15. Adjacent cultivation containers 1 are connected in series by a connecting pipe 14. Figure 8 As shown, water is supplied to the cultivation bucket 1 by water pump 13. When the water level in the cultivation bucket 1 rises above the position of the first connecting pipe 2, the excess water flows out from the first connecting pipe 2. When water flows out from the first connecting pipe 2 in all the arranged cultivation buckets 1, it proves that each cultivation bucket 1 is full of water. The water pump 13 can be stopped, and the outflowing water enters the receiving trough set on the side of the cultivation bucket 1. The water in the receiving trough flows back into the water storage tank 15.

[0036] Alternatively, cultivation containers can be arranged from high to low, with a water pump supplying water to the highest container. Once full, the water flows out through the first connecting pipe 2 to supply water to the containers below, and so on. The bottom container will return excess water to the storage tank for recycling. The water pump is connected to a timer control switch to achieve automatic water supply. This arrangement can be used on hillsides.
