A three-state planting device

Abstract

This utility model discloses a three-state planting device, including a cultivation container, a planting frame, a degradable membrane, and a hole system. The hole system includes high-level holes and low-level holes. The planting frame is set inside the cultivation container, positioned between the high-level holes and the low-level holes, dividing the interior of the cultivation container into a liquid zone, an air zone, and a substrate zone. The degradable membrane covers the air zone and the substrate zone. Plant roots can penetrate the degradable membrane from the substrate zone and extend into the air zone and the liquid zone through growth. Nutrient solution is stored in the liquid zone, allowing partial substrate immersion. The planting frame maintains the space in the air zone. The substrate zone is covered by the degradable membrane. The low-level holes located at the top of the liquid zone serve as both air intake and liquid overflow, while the high-level holes located at the top of the air zone serve as both air exhaust and liquid replenishment, forming a dynamically interactive plant growth space. This naturally regulates the plant's growth temperature, humidity, and environmental parameters, adapting to the needs of the plant throughout its entire growth cycle, and avoiding soil compaction and root growth restrictions caused by traditional physical barriers.

Description

Technical Field

[0001] This utility model relates to the field of planting device technology, specifically to a three-state planting device. Background Technology

[0002] Currently, in plant cultivation, existing technologies address the problem that planters can only cultivate a single type of plant, allowing them to grow different types. Alternatively, existing technologies can solve the problem of forgetting to water plants, which directly affects photosynthesis and can even cause plants to die from dehydration.

[0003] The common problem with existing technologies is that there is an irreconcilable contradiction between static environment architecture and dynamic growth requirements.

[0004] 1. Rigid environmental adaptation: Traditional cultivation systems (with soil / without soil) use static, fixed, and isolated structures, which are difficult to match the needs of plants throughout their entire growth cycle;

[0005] 2. Physical growth barriers: Soil compaction and physical barriers hinder the natural extension of roots;

[0006] 3. High control costs: It relies on manual labor or high-energy-consuming equipment to adjust and maintain environmental parameters and temperature and humidity.

[0007] Therefore, there is an urgent need for a plant growth and cultivation device that can autonomously match environmental parameters with the physiological needs of plants. Utility Model Content

[0027] Please see Figures 1-6This utility model provides a technical solution: a three-state planting device, including a cultivation container 1, a planting frame 2, a degradable membrane 4, and a hole system; the hole system is formed on the side wall of the cultivation container 1, including a high-position hole 301 and a low-position hole 302, wherein the high-position hole 301 is positioned higher than the low-position hole 302 in the vertical direction; the planting frame 2 is placed inside the cultivation container 1, and its position is between the high-position hole 301 and the low-position hole 302, dividing the interior of the cultivation container 1 into a liquid zone, which is used for... The container has a hollow cavity for storing nutrient solution or water, and a substrate zone for placing nutrient soil and planting plants. The area between the top opening of the cultivation container 1 and the planting frame 2 is the substrate zone, the area between the planting frame 2 and the low hole 302 is the air zone, and the area between the low hole 302 and the bottom of the cultivation container 1 is the liquid zone. The degradable membrane 4 is cut to a suitable size and placed between the air zone and the substrate zone. Plant roots can penetrate the degradable membrane 4 from the substrate zone and extend into the air zone and the liquid zone as they grow.

[0028] Here, the degradable membrane 4 can be selected from one of the following: starch-based degradable membrane, chitosan-based degradable membrane, polylactic acid degradable membrane, and starch / polylactic acid composite membrane.

[0029] The high-position hole 301 and the low-position hole 302 can be opened in pairs, and based on the symmetry of the cultivation container 1, two or more sets can be opened according to the size of the cultivation container 1 and the growth environment of the crop to be planted, so as to facilitate air circulation inside the cultivation container 1.

[0030] The planting framework 2 has a preferred shape, such as bowl-shaped, inverted bowl-shaped, or arch-shaped. The planting framework 2 has a hollow structure to connect the air zone and the substrate zone, allowing gas from the air zone to enter the substrate zone to improve soil aeration. Water from the liquid zone can also enter the substrate zone through evaporation to ensure soil moisture. Similarly, plant roots can pass through the substrate zone to directly enter the air zone and liquid zone, increasing the growth space for plant roots.

[0031] Specifically, the hollow structure can be a space formed by the rod-shaped connection of the planting frame 2 to form a closed loop, or it can be a gap hole 201 drilled through the planting frame 2. As another embodiment of this utility model, the size and spatial layout of the gap hole 201 can be designed such that the hole at the top is large and the hole extending downward is small. The purpose is to better fit the growth characteristics of the plant, that is, the main root system that grows vertically downward is thicker and can better pass through the large hole, while the roots that extend from the main root system to the surrounding area are thinner and can pass through the small hole, so that the root system has a better spatial layout and nutrient absorption method.

[0032] The high-position hole 301 is located at 3 / 4 of the distance from the bottom of the cultivation container 1 to ensure sufficient height above the top of the air zone. This allows gas from the air zone to move effectively through the substrate zone when moving towards the high-position hole 301, improving soil permeability. Similarly, when forced aeration or nutrient solution is injected through the high-position hole 301, the medium can pass through the substrate zone before entering the air or liquid zone. The low-position hole 302 is located at 1 / 4 of the distance from the bottom of the cultivation container 1 to provide sufficient storage space in the liquid zone while allowing excess liquid to overflow and drain in time, preventing excessive liquid medium from accumulating and causing root rot. This method allows for dynamic and continuous oxygen supply to the air zone. In the experiment, the root rot rate of strawberries decreased from 20% to 2%. Some plants extended their aquatic roots into the liquid zone, increasing the length of the taproot by 20% and enhancing plant growth.

[0033] Here, the space from the low hole 302 to the high hole 301 or the space to the top opening of the cultivation container 1 can form a gas exchange, that is, to use the chimney effect to improve the permeability of the soil in the substrate area, which not only prevents soil compaction, but also changes the temperature and humidity of growth.

[0034] As another embodiment of this utility model, both the high-position hole 301 and the low-position hole 302 are provided with an expansion interface, that is, a threaded connector, which can be connected to an external ventilation device or a liquid injection device to force the gas or liquid to circulate in the liquid zone, gas zone and substrate zone. Alternatively, a temperature and humidity sensor can be added to better monitor the plant growth environment.

[0035] In this invention, nutrient solution is stored in the liquid zone, allowing partial immersion of the substrate. The planting framework 2 maintains the air zone space, and the substrate zone is covered by the degradable membrane 4. The low-position hole 302 located at the top of the liquid zone serves both as an air intake and an overflow, while the high-position hole 301 located at the top of the air zone serves both as an exhaust and a replenishment, forming a dynamically interactive plant growth space. This naturally regulates the plant's growth temperature, humidity, and environmental parameters, adapting to the needs of the plant throughout its entire growth cycle. It also avoids soil compaction and the root growth restriction caused by traditional physical barriers. The dynamic coupling of the substrate zone and the liquid zone increases the root expansion space by more than 200%, and the degradable membrane 4 can be 100% converted into plant nutrients, reducing environmental pollution.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
