Description

Technical Field

[0001] This utility model relates to the field of agricultural crop cultivation equipment technology, specifically to a rice cultivation pot based on capillary self-watering and root oxygenation. Background Technology

[0002] Currently, the traditional methods widely used in rice seedling cultivation mainly include plastic seedling tray cultivation and direct seeding in the paddy field. Although these methods can meet production needs under certain conditions, they still have the following prominent problems: 1. Water management is difficult and uneven. Traditional seedling cultivation methods rely heavily on artificial irrigation, which easily leads to localized over-drying or waterlogging, affecting seed germination and seedling growth uniformity; 2. Insufficient root oxygen supply. Water easily accumulates at the bottom of the substrate in the paddy field or ordinary seedling containers, hindering air from entering the root area, resulting in root hypoxia, affecting seedling respiration and nutrient absorption, and even causing root rot; 3. Low fertilizer utilization rate. In traditional seedling cultivation, some of the fertilizer applied is lost through water seepage or evaporation, making it difficult to continuously and stably supply to the root area, which not only wastes resources but may also pollute the environment. Therefore, there is an urgent need to develop a new type of rice seedling cultivation device that can achieve automatic water supply, effective oxygenation, easy management, and simple structure to overcome the shortcomings of existing technologies and create a suitable environment for cultivating robust rice seedlings. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a rice seedling tray with a simple structure and low cost, which can realize automatic and stable water supply, and at the same time effectively increase the oxygen content in the seedling substrate, creating an ideal environment of "sufficient water and fertilizer and breathable air" for the rice seedling roots, cultivating high-quality rice and laying the foundation for high yield.

[0004] To solve the above problems, this utility model provides the following technical solution:

[0005] A rice cultivation pot based on capillary self-watering and root aeration; it includes a pot body with an open top; a partition is provided in the inner cavity of the pot body; the partition is placed horizontally and divides the pot body into an upper cultivation area for placing seedling substrate and cultivating seedlings and a lower water storage area for storing liquid fertilizer and water; several capillary fiber ropes are provided on the partition; one end of the capillary fiber rope is placed at the bottom of the water storage area, and the other end extends through the partition into the seedling substrate located in the cultivation area; the capillary fiber ropes can transport water in the water storage area to the seedling substrate in the cultivation area through capillary action; several ventilation holes are opened on the side wall of the pot body at a position above the highest water storage height of the water storage area.

[0007] The bottom of the water storage area is a sloping structure; the water inlet is located on the higher side of the slope, and a closable cleaning drain valve is also installed on the water storage area at the position corresponding to the bottom of the slope.

[0008] Preferably, the partition is a grid-like flat plate component with multiple ventilation holes; the capillary ropes are arranged by passing through the ventilation holes on the partition.

Water and fertilizer saving, convenient management: Through the automatic capillary water supply mechanism of capillary fiber ropes, water and dissolved fertilizer in the water storage area can be continuously and evenly delivered to the seedling substrate, reducing water evaporation and seepage losses and significantly improving water and fertilizer utilization efficiency. At the same time, the design of the observation window and water inlet allows users to intuitively monitor the water level and replenish water in time, reducing the difficulty of daily management.

[0013] 2.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0021] Example:

[0022] Reference Figure 1 This embodiment provides a rice cultivation pot based on capillary self-watering and root aeration. It includes a pot body 1 with an open top; a partition 2 is installed inside the pot body 1; the partition 2 is placed horizontally and divides the pot body into an upper cultivation area 11 for placing seedling substrate and cultivating seedlings, and a lower water storage area 12 for storing liquid fertilizer and water; several capillary fiber ropes 3 are installed on the partition 2; one end of each capillary fiber rope 3 is placed at the bottom of the water storage area 12, and the other end extends through the partition 2 into the seedling substrate in the cultivation area 11; the capillary fiber ropes 3 can transport water from the water storage area to the seedling substrate in the cultivation area 11 through capillary action; several ventilation holes 13 are opened on the side wall of the pot body 1 at a position above the highest water storage height of the water storage area 12. The capillary action provided by the capillary fiber ropes can continuously and evenly transport water from the water storage area to the entire substrate, achieving automatic water replenishment. The partition separates the seedling substrate from the top of the water storage area, forming an air gap. This prevents the bottom of the substrate from being constantly submerged in water, creating a moist but not wet, breathable environment for the roots. Furthermore, the vent design ensures no water leakage when the water level in the storage area is normal, while still allowing direct air exchange with the lower and middle parts of the seedling substrate. In practical applications, the capillary ropes can be made of hydrophilic synthetic or natural fiber materials to ensure long-term stable water transport performance.

[0023] The basin 1 is made of an opaque material. An observation window 14 is installed on the side wall of the basin 1 at the location corresponding to the water storage area 12, for observing the water level in the storage area 12. An inlet 15 for replenishing water into the storage area is also located at this location. The observation window and inlet are designed to determine the water level in the storage area based on actual water usage needs, allowing for timely replenishment. The opaque basin effectively prevents direct sunlight from reaching the water storage area, inhibiting algae growth and avoiding ineffective nutrient consumption. In this embodiment, the observation window is made of a transparent, wear-resistant material and embedded in the basin. A water level line is marked on the observation window for easier and more intuitive water level management by the user.

[0024] The bottom of the water storage area 12 has a sloping structure; the inlet 15 is located on the higher side of the slope, and a closable cleaning drain valve 17 is also installed on the water storage area 12 at the position corresponding to the bottom of the slope. The sloping bottom of the water storage area is designed to facilitate the filling and cleaning of the water storage area with water through the inlet and the cleaning drain valve without disassembling the basin, thereby achieving the effect of replacing different nutrients in the water storage area; this sloping structure, together with the cleaning drain valve, can also be used to periodically remove deposited impurities, which helps to maintain the cleanliness of the nutrient solution and reduce the risk of bacterial growth.

[0025] The partition 2 is a grid-like flat plate component with multiple air vents; the capillary ropes 3 are arranged by passing through the air vents on the partition 2. The partition not only serves as a physical barrier, but its grid structure also helps to increase the overall air permeability of the substrate in the culture zone, further optimizing the gas environment in the root zone and promoting healthy root development.

[0026] Several positioning plates 4 are installed on the side wall of the inner cavity of the basin 1; the partition 2 is detachably placed on the positioning plates 4. This detachable structure makes it convenient for users to install, replace or clean the partition and capillary rope, improving the maintainability and flexibility of the product.

[0027] Several overflow valves 16, whose opening and closing states can be manually controlled, are located on the side wall of the pot 1. The overflow valves 16 are positioned above the soil substrate laid in the cultivation area 11, and each overflow valve 16 has a different height. The overflow valves are used to control the water level at the surface of the soil in the cultivation area after rainfall. Different overflow valves can be set at different heights according to different growth stages of rice, thereby addressing the impact of flooding on rice growth during rainy weather. The multi-height overflow valves allow users to flexibly adjust the water level according to the flood tolerance of rice at different growth stages, enhancing the adaptability of the cultivation pot to variable climates and effectively preventing waterlogging damage.

[0028] When using the utility model device in this embodiment, the following steps can be referred to:

[0029] 1. Install the partition into the basin at an appropriate height using the positioning clips, ensuring it is placed stably.

[0030] 2. Pass one end of the capillary rope through the ventilation hole of the partition and extend it to the culture area, while the other end hangs down to the bottom of the water storage area.

[0031] 3. Fill the cultivation area with seedling substrate, level it, and then sow or transplant seedlings.

[0032] 4. Inject an appropriate amount of water and liquid fertilizer into the water storage area through the inlet.

[0033] 5. Monitor the water level through the observation window and replenish water and fertilizer regularly.

[0034] 6. Adjust the opening and closing status of the overflow valves at different heights according to the weather and growth stage to control the surface water level.

[0035] 7. After the seedlings have grown, the partition can be removed to take out the seedlings with intact root systems for transplanting.
