Abstract
Description
Technical Field
[0001] This utility model relates to the field of blueberry cultivation technology, and more specifically, to a planting pot. Background Technology
[0002] The health of the root system is crucial for blueberry cultivation and growth. Currently, there are two main problems encountered in blueberry cultivation and production:
[0003] First, black plastic planting pots easily absorb heat. In the summer, when the air temperature inside the greenhouse exceeds 38°C, root growth is easily affected.
[0004] Secondly, through drip irrigation, water seeps from the top to the bottom. During the blueberry growth process, the small particles of the substrate sink, which can easily lead to water accumulation at the bottom of the substrate, while the top of the substrate dries out easily, causing salt accumulation.
[0005] Some commercially available double-layered flowerpots offer some insulation due to their double-layer design, and the addition of ventilation holes enhances airflow, further reducing temperature and mitigating the impact of high summer temperatures on root growth. However, these double-layered flowerpots are primarily used for hydroponics, utilizing the double-layered structure to retain water and minimize frequent watering. This does not eliminate the problem of waterlogging at the bottom. Utility Model Content

[0009] Preferably, the bottom of the outer basin is convex at the middle position, the drain hole is located in the center of the convex part, and the bottom of the outer basin is equipped with a support foot. The support foot is a hollow structure and is equipped with reinforcing ribs inside.
[0010] Preferably, the bottom of the inner basin is recessed in the middle and rests against the bottom of the outer basin. The drain hole is centered in the recessed part, and the diameter of the drain hole at the bottom of the inner basin is smaller than that at the bottom of the outer basin.
[0011] Preferably, the bottom of the inner basin has multiple ribs distributed circumferentially around the drain hole, with the length direction of the ribs all pointing towards the drain hole. The ribs avoid the sunken parts, and the drainage groove is formed between adjacent ribs.
[0012] Preferably, multiple arc-shaped air intake channels are distributed circumferentially at the bottom of the air flow interlayer. Both ends of the arc-shaped air intake channels are connected to the side wall of the outer basin.

[0026] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Example 1:
[0028] Please refer to the following: Figures 1 to 3 This embodiment provides a planting pot, comprising: a double-layer structure consisting of an inner pot 10 and an outer pot 11, with an airflow interlayer 12 located between the inner pot 10 and the outer pot 11; the inner pot 10 is black in color, and the outer pot 11 is white in color; the inner pot 10 has internal ventilation holes 13 located at the lower side of 2 / 3 of the height of the inner pot 10; the outer pot 11 has external ventilation holes 14 located at the lower side of 2 / 3 of the height of the outer pot 11; and drainage holes 15 are located at the bottom of the inner pot 10 and the outer pot 11.
[0029] The working principle and beneficial effects of the above technical solution are as follows:
[0030] This utility model discloses a planting pot with a double-layer structure consisting of an inner pot 10 and an outer pot 11, which provides a certain degree of heat insulation. The outer pot 11 is white, which reflects sunlight and can lower the temperature by 3-5°C, reducing heat absorption and preventing damage to the root system from high summer temperatures. The inner pot 10 is black, which inhibits algae growth and promotes a light-protected environment for the roots (blueberry roots are sensitive to light). The airflow layer enhances air circulation within the pot, preventing waterlogging at the bottom of the substrate that could lead to root rot, and also preventing salt accumulation caused by dryness at the top of the substrate. Drainage holes 15 are provided at the bottom of both the inner pot 10 and the outer pot 11, allowing drip irrigation water to drain out promptly.
[0031] Salt accumulation is often caused by excessively rapid water evaporation, insufficient water replenishment, or inadequate lateral water diffusion. The internal vents 13 and external vents 14 are located at the lower two-thirds height of the inner basin 10 and the lower two-thirds height of the outer basin 11, respectively. This eliminates the need for vents at the upper two-thirds height of the inner basin 10 and the upper two-thirds height of the outer basin 11, thus reducing substrate water evaporation and consequently minimizing salt accumulation at the top of the substrate.
[0032] In this embodiment, a fixed cover plate 16 is installed at the mouth end of the inner basin 10. The fixed cover plate 16 is arranged in a ring shape, and an outward flange 17 for supporting the fixed cover plate 16 is installed at the mouth end of the outer basin 11.
[0033] The working principle and beneficial effects of the above technical solution are as follows:
[0034] The design of the fixed cover plate 16 and the outward flange 17 improves the structural stability between the inner basin 10 and the outer basin 11. On the other hand, the fixed cover plate 16 makes the airflow interlayer 12 relatively sealed, which plays a role in heat insulation.
[0035] In this embodiment, the inner vent 13 and the outer vent 14 are distributed with increasing density from top to bottom. The number of inner vent 13 and outer vent 14 in each ring is 7-12, and the vent diameter is 5-9 mm.
[0036] The working principle and beneficial effects of the above technical solution are as follows:
[0037] The internal vents 13 and external vents 14 are staggered, thus diversifying the airflow paths within the airflow interlayer 12. This enhances air circulation within the pot, prevents waterlogging at the bottom of the substrate that could lead to root rot, and also prevents salt accumulation caused by dryness at the top of the substrate.
[0038] In this embodiment, the bottom of the outer basin 11 is convex at the middle position, the drain hole 15 is centrally located at the convex part, and the bottom of the outer basin 11 is equipped with a support foot 18. The support foot 18 is a hollow structure and is provided with reinforcing ribs inside.
[0039] The above technical solution and its beneficial effects are as follows:
[0040] The bottom of the outer basin 11 is convex at the middle position and abuts against the bottom of the inner basin 10, thereby improving the structural stability between the inner basin 10 and the outer basin 11.
[0041] In this embodiment, the bottom of the inner basin 10 is recessed in the middle and abuts against the bottom of the outer basin 11. The drain hole 15 is centrally located in the recessed part, and the diameter of the drain hole 15 at the bottom of the inner basin 10 is smaller than that of the drain hole 15 at the bottom of the outer basin 11.
[0042] The above technical solution and its beneficial effects are as follows:
[0043] The bottom of the inner basin 10 is recessed in the middle to facilitate the accumulation of water, which is then discharged through the drain hole 15.
[0044] In this embodiment, multiple ribs 19 are distributed circumferentially around the drain hole 15 at the bottom of the inner basin 10. The length direction of the ribs 19 all points to the drain hole 15. The ribs 19 avoid the sunken parts, and the drainage groove is formed between adjacent ribs 19.
[0045] The working principle and beneficial effects of the above technical solution are as follows:
[0046] The ribs 19 reduce the bulk density of the substrate at the bottom of the inner basin 10, increase the flowability of water at the bottom of the inner basin 10, facilitate the drainage of water, and the formed drainage channel facilitates the concentration of water towards the drain hole 15.
[0047] Example 2:
[0048] Please refer to the following: Figures 4 to 6 Based on the above embodiment 1, multiple arc-shaped air intake channels 21 are distributed circumferentially at the bottom of the air flow interlayer 12. Both ends of the arc-shaped air intake channels 21 are connected to the side wall of the outer basin 11. An annular channel 22 is embedded in the side wall of the inner basin 10. The annular channel 22 abuts against the arc-shaped air intake channel 21. An air inlet 23 is provided in the middle of the arc-shaped air intake channel 21. An air inlet 24 suitable for the air inlet 23 is provided on the annular channel 22.
[0049] The central part of the arc-shaped air intake channel 21 is recessed to fit the annular channel 22. The inner wall of the annular channel 22 is densely covered with fine holes at the position where it is close to the inner basin 10.
[0050] The working principle and beneficial effects of the above technical solution are as follows:
[0051] When it is necessary to improve the evaporation of water accumulated at the blueberry root system, manually rotate the outer pot 11 so that the arc-shaped air intake channel 21 connected to the outer pot 11 slides on the annular channel 22, and the air inlet 1 23 and the air inlet 24 are connected, thereby connecting the arc-shaped air intake channel 21 and the annular channel 22. Air is sent into the bottom of the inner pot 10 through the fine holes, thereby improving the air flow at the bottom of the inner pot 10, facilitating the evaporation of water accumulated at the blueberry root system, and preventing water accumulation from causing root rot.
[0052] When it is necessary to maintain humidity around the blueberry roots, manually rotate the outer pot 11 in the opposite direction. This will cause the arc-shaped air intake channel 21 connected to the outer pot 11 to slide in the opposite direction on the annular channel 22, thus disconnecting the air inlet 23 and the air inlet 24. In this way, air cannot be delivered into the annular channel 22, and the air flow at the bottom of the inner pot 10 cannot be improved.
[0053] In this embodiment, there are 6 arc-shaped air intake channels 21.
[0054] In this embodiment, position marks are provided on the fixed cover plate 16 and the outward flange 17 to determine the communication status between the first air outlet 23 and the second air outlet 24.
[0055] The working principle and beneficial effects of the above technical solution are as follows:
[0056] The location markers facilitate visual observation of the connection status between air inlet 1 23 and air inlet 24.
[0057] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
