Description

Technical Field

[0001] The present invention relates to the technical field of horticultural cultivation, and more specifically, to a three-dimensional ventilation system for plant roots based on a water-soluble PVA film and a method for using the same. Background Art

[0002] Traditional flower pots (ceramic, plastic, etc.) rely on a single air hole at the bottom, and the side walls have poor air permeability, which can easily lead to soil compaction and root hypoxia. Existing air permeable layer materials (such as perlite) can only be used as the bottom or top surface, and it is difficult to evenly fit the pot wall. The air permeability is poor, and it is easy to powder and fail after long-term use. It is difficult to balance air permeability and water retention. Excessive air permeability can easily lead to water loss, affecting plant growth.

[0003] Patent CN222216575U discloses a water-storing, breathable and draining flowerpot, which improves soil permeability by physically opening holes. However, the air holes are easily blocked by soil particles, and only partial air permeability can be achieved, and a three-dimensional circulation channel cannot be formed.

[0004] Patent CN119073121A discloses a multifunctional, environmentally friendly and energy-saving flower pot, which uses a honeycomb ceramic tube containing volcanic stone. Although it has air permeability and water retention functions, the material preparation process is complicated and costly, and the air permeability gradually deteriorates with aging of the material, making it difficult to promote on a large scale.

[0005] The existing technology is difficult to meet the dual needs of potted plants for efficient ventilation and environmental protection due to its complex structure, unsustainable materials or single function. The present invention realizes the dynamic construction of the breathable layer, the unification of environmental degradation and long-term function through the innovative combination of water-soluble PVA film and functional medium, providing a breakthrough solution for the field of horticultural cultivation. Summary of the invention

[0006] In order to solve the above problems in the prior art, one of the purposes of the present invention is to provide a three-dimensional plant root ventilation system based on a water-soluble PVA film, comprising:

[0007] At least one water-soluble breathing core packaging unit, wherein the water-soluble breathing core packaging unit is formed by wrapping air-permeable medium particles with a PVA packaging layer;

[0008] A flower pot, wherein a layer of air-permeable medium particles is laid on the bottom of the flower pot, and the water-soluble breathing core packaging unit is laid around the inner wall;

[0009] Planting soil, filled on the air-permeable medium particles and inside the water-soluble breathing core packaging unit;

[0010] A layer of air-permeable medium particles is laid on the planting soil.

[0011] The PVA encapsulation layer is a cold-water-soluble polyvinyl alcohol film with a thickness of 0.02 - 0.2 mm and a dissolution time ≤ 30 minutes at a water temperature of 25°C.

[0012] The breathable medium particles are at least one of volcanic stone particles, ceramsite, charcoal particles, or bamboo charcoal particles.

[0013] The breathable medium particles have a particle size of 3 - 20 mm and a porosity > 60%.

[0014] The breathable medium particles are mixed with one or more of slow-release organic fertilizer particles, antibacterial particles, and oxygen-increasing agent particles.

[0015] The slow-release organic fertilizer particles are at least one of compound slow-release fertilizer particles, bio-organic fertilizer particles, or coated urea particles; the antibacterial particles are at least one of microbial particles containing antagonistic bacteria, sulfur particles, nano-silver antibacterial particles, or porous carbon-based antibacterial particles; the oxygen-increasing agent particles are at least one of sodium percarbonate particles, calcium peroxide particles, or potassium monopersulfate compound salt particles.

[0016] The water-soluble breathing core encapsulation unit has a strip structure with a thickness of 1 - 3 cm and a length of 10 - 25 cm.

[0017] The bottom of the flowerpot is provided with drainage holes.

[0018] The second object of the present invention is to provide a method for using a three-dimensional breathable system for plant roots, including the following steps:

[0019] a. Lay a layer of breathable medium particles at the bottom of the flowerpot;

[0020] b. Surround and lay the water-soluble breathing core encapsulation unit on the inner wall of the flowerpot;

[0021] c. Fill the planting soil above the breathable medium particles and inside the water-soluble breathing core encapsulation unit, plant the plants, and then lay a layer of breathable medium particles on the surface;

[0022] d. Water to dissolve the PVA encapsulation layer, and the breathable medium particles fit with the planting soil to form a breathable structure, realizing the air circulation in the plant root area.

[0023] In step b, for special-shaped flowerpots, use PVA water-soluble double-sided tape to bond the encapsulation unit to the inner wall of the flowerpot.

[0024] The three-dimensional breathable system for plant roots based on water-soluble PVA film and its using method of the present invention have the following advantages:

[0025] 1. After watering, the PVA encapsulation layer of the present invention dissolves, enabling the volcanic rock particles to closely adhere to the planting soil, dynamically forming a breathable structure according to soil humidity and plant growth requirements, effectively avoiding the fixed defects of traditional breathable structures.

[0026] 2. The breathable medium particles at the bottom and surface of the present invention cooperate with the breathable medium particles in the water-soluble breathing core encapsulation unit surrounded by the inner wall, forming a three-dimensional breathable network from the bottom to the top of the flowerpot and from the inner wall to the center, greatly increasing the breathable area, improving the air circulation efficiency, and ensuring that all parts of the plant roots can obtain sufficient oxygen.

[0027] 3. The breathable medium particles of the present invention not only have good breathability, but their pores can also store a certain amount of water, playing a role in water retention. At the same time, the mixed slow-release organic fertilizer particles can provide long-term nutrients for plant growth, and the antibacterial particles can effectively inhibit harmful microorganisms in the soil, reducing the occurrence of plant diseases.

[0028] 4. The present invention combines environmental protection, adaptability and long-term effectiveness, and is applicable to home gardening and large-scale planting.

[0029] 5. After the PVA membrane dissolves, it generates water and CO2, without plastic pollution and other residues. Description of the Drawings
