[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The purpose of the utility model is to provide an underground bag-type cultivation device for high-quality tomatoes, so as to solve the problems existing in the prior art, make the substrate temperature more stable, and maintain the vitality of the crop root system.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Please refer to Figure 1 This embodiment provides an underground bag-type cultivation device for high-quality tomatoes, including a cultivation tube 7 arranged in a pit 6, the upper edge of the pit 6 corresponding to the upper position of the cultivation tube 7; a cultivation bag 5 containing a substrate 9 is arranged in the cultivation tube 7, and the upper surface of the substrate 9 is no higher than the upper edge of the pit 6; and air holes 8 are opened on the cultivation bag 5.

[0026] The working principle of this embodiment is:

[0027] Shallow geothermal energy, or shallow geothermal resources, refers to the low-temperature heat stored in the soil, gravel, and groundwater within a few hundred meters of the Earth's surface. It is primarily derived from solar radiation, with a small portion derived from heat from the Earth's core. It is a renewable energy source with a generally constant temperature. Compared to the air temperature above ground, the shallow surface temperature is lower in the summer and higher in the winter, making it closer to the ideal temperature for crop root growth.

[0028] In this embodiment, a cultivation tube 7 is placed in a pit 6 dug in the ground surface, with the upper edge of the pit 6 aligned with the upper portion of the cultivation tube 7, ensuring that most of the cultivation tube is enclosed by the pit 6. A cultivation bag 5 containing a substrate 9 is then placed in the cultivation tube 7, ensuring that the upper surface of the substrate 9 is no higher than the upper edge of the pit 6. Because the pit 6 encloses most of the cultivation tube 7, ground heat from the shallow surface is transferred through the cultivation tube 7 to the substrate 9 in the cultivation bag 5. The relatively constant ground heat from the shallow surface is used to maintain a stable temperature of the substrate 9 in the cultivation tube 7, thereby maintaining the vitality of the crop root system and ensuring the quality and yield of the crop.

[0029] Among them, the cultivation tube 7 can be made of PVC material, which has the following functions: first, preventing the inner wall of the pit 6 from falling down and causing landslides, thereby improving the strength and stability of the pit 6 structure; second, avoiding direct contact between the cultivation bag 5 and the inner wall of the pit 6 to generate friction and damage the cultivation bag 5; third, since the material of the cultivation bag 5 is relatively soft, if the cultivation bag 5 is directly placed in the pit 6, the shallow surface soil will move due to various reasons, and the matrix 9 and the soil will slowly embed into each other and gradually combine together through the cultivation bag 5, resulting in the inability to smoothly remove the cultivation bag 5 when planting or pulling seedlings in the later stage. The PVC tube has higher hardness and strength than the cultivation bag 5. A PVC tube is set between the cultivation bag 5 and the soil as an isolation layer. When the crops need to be transplanted, the cultivation bag 5 can be directly lowered and lifted upwards, which greatly reduces labor and saves labor time.

[0030] Specifically, the top of the cultivation tube 7 is higher than the upper edge of the pit 6 , preferably 1-2 cm above the ground surface, to prevent soil on the inner wall of the pit 6 from falling into the matrix 9 in the cultivation bag 5 .

[0031] At the same time, in order to facilitate the direct lifting of the cultivation bag 5 when transplanting crops, the top of the cultivation bag 5 is set higher than the top of the cultivation tube 7, preferably 5-10 cm higher than the top of the cultivation tube 7. The size of the cultivation bag 5 is preferably 20-50 cm high and 10-15 cm in diameter.

[0032] The air holes 8 provided on the cultivation bag 5 are used to ensure breathing of the plant roots and for drainage. As a preferred embodiment of this embodiment, the air holes 8 are provided on the lower sidewalls of the cultivation bag 5, for example, at a height of 5-10 cm from the bottom of the bag 5. Four air holes 8 are provided on each of the four sides of the bag, ensuring that water can be drained away smoothly without draining away too quickly, thereby avoiding the need for constant watering to ensure adequate water supply and conserving water resources.

[0033] This embodiment also includes a drip irrigation belt 1 for watering and fertilizing crops planted in the cultivation bags 5. The drip irrigation belt 1 is provided with drip irrigation ports 2 corresponding to the openings of the cultivation bags 5. In actual scenarios, one drip irrigation belt 1 can correspond to multiple cultivation bags 5 arranged in a row, and the drip irrigation belt 1 has multiple drip irrigation ports 2 corresponding one to one with the cultivation bags 5.

[0034] As a preferred solution of this embodiment, each drip irrigation port 2 on the drip irrigation belt 1 is provided with a drip arrow 4 for guiding water and fertilizer to the substrate 9 in the cultivation bag 5. The drip arrow 4 is connected to the drip irrigation port 2 through a connecting pipe 3, and a valve body for controlling the water flow size can also be provided on the connecting pipe 3.

[0035] The utility model adopts an underground bag cultivation method, watering and fertilizing are carried out through a drip irrigation belt 1 and a drip arrow 4. At the same time, a PVC cultivation tube 7 is placed underground, a cultivation bag 5 is placed in the cultivation tube 7, and a matrix 9 is contained in the cultivation bag 5. An air hole 8 is opened 5 cm from the bottom of the bag to facilitate the breathing and drainage of plant roots, while the soil is used for heat preservation. The management is convenient and there are almost no disadvantages.

[0036] Adaptive changes based on actual needs are all within the protection scope of this utility model.

[0037] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from all perspectives, the embodiments should be regarded as illustrative and non-restrictive.
