Description

Technical Field

[0001] This utility model relates to the field of rock wool composites, and more particularly to a hydrophilic rock wool composite for planting. Background Technology

[0002] With the development of hydrophilic rock wool composites for planting, more and more hydrophilic rock wool composites for planting are being used in soilless cultivation in facility agriculture, seedling and cutting propagation, and planting in special environments. Reasonable application can reduce management costs, reduce planting difficulty, reduce diseases, increase yield and appearance, and overcome environmental limitations to expand planting space.

[0003] A search revealed that CN218999146U discloses a hydrophilic agricultural rock wool composite, comprising a first hydrophobic rock wool board layer, a second hydrophilic agricultural rock wool layer, and a second hydrophobic rock wool board layer. The first hydrophobic rock wool board layer is positioned above the first hydrophobic rock wool board layer, and a nutrient crystal layer is positioned above the first hydrophilic agricultural rock wool layer. The second hydrophilic agricultural rock wool layer is positioned above the nutrient crystal layer, and the second hydrophobic rock wool board layer is positioned above the second hydrophilic agricultural rock wool layer. This design solves the problem of using a corrugated lamination process in existing devices to composite rock wool. Rock wool substrates consume more material than ordinary rock wool substrates, indirectly increasing their cost. This utility model has a reasonable structure and good practicality. It can ensure the absorption of nutrients and water by plants without the need for corrugated lamination processing to form rock wool substrates. It also has good light transmittance, air permeability and water retention, and the cost is reduced by at least 20%. Existing structures and patents have problems such as insufficient structural stability, easy compaction and loss of air permeability, extensive nutrient supply and lack of targeted release. Therefore, a hydrophilic rock wool composite for planting is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a hydrophilic rock wool composite for planting, which aims to improve the problems of insufficient structural stability, easy compaction and air permeability failure, extensive nutrient supply and lack of targeted release in the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A hydrophilic rock wool composite for planting includes a base and a biodegradable protective outer layer. The top of the base is provided with the biodegradable protective outer layer, and the inner wall of the biodegradable protective outer layer is provided with an inner protective layer.

[0007] The inner protective layer contains a slow-release nutrient core sphere, and the top of the slow-release nutrient core sphere is covered with a lower layer of low-hydrophilic rock wool.

[0008] As a further description of the above technical solution:

[0009] The top of the lower low-hydrophilic rock wool layer is fixedly connected to a glass fiber support column.

[0010] As a further description of the above technical solution:

[0011] The top of the glass fiber support column is fixedly connected to an upper layer of low hydrophilic rock wool.

[0012] As a further description of the above technical solution:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a hydrophilic rock wool composite for planting, comprising a base 1 and a biodegradable protective outer layer 2. The base 1 provides bottom support for the entire rock wool composite, ensuring structural stability and bearing the weight of the upper components and planting forces. The top of the base 1 is provided with a biodegradable protective outer layer 2, which wraps around the outside of the composite to prevent rock wool fibers from scattering and polluting the environment, and is biodegradable; at the same time, it isolates external impurities from entering the interior. The inner wall of the biodegradable protective outer layer 2 is provided with an inner protective layer 10.

[0028] The inner protective layer 10 contains a slow-release nutrient core ball 9, which encapsulates nutrients and releases them slowly as water permeates, providing precise and continuous nutrient supply to match the nutritional needs of crops during their growth period and improve fertilizer utilization. The top of the slow-release nutrient core ball 9 is provided with a lower low-hydrophilic rock wool layer 3, which is located at the bottom of the composite. Its low hydrophilicity slows down the rapid loss of water and works with the upper layer to maintain water balance, providing a stable humidity environment for the roots.

[0029] Example 2:

[0030] Reference Figures 1-3The lower low-hydrophilic rock wool layer 3 is fixedly connected to the top of a glass fiber support column 4. The glass fiber support column 4 is interspersed between the upper and lower rock wool layers, providing rigid support and preventing the rock wool layer from being compacted due to pressure. This ensures the permeability of the pores and prevents root hypoxia. The upper low-hydrophilic rock wool layer 5 is fixedly connected to the top of the glass fiber support column 4. The upper low-hydrophilic rock wool layer 5 is located at the top of the composite. Its low hydrophilicity reduces water transpiration into the air, preventing the surface from drying out too quickly. It works in conjunction with the lower layer to achieve gradient water retention. The top of the upper low-hydrophilic rock wool layer 5 is equipped with hemispherical slow-release nutrient beads 6. The hemispherical slow-release nutrient beads 6 are distributed in a hemispherical shape and can slowly release customized nutrients, preventing root burn from excessive fertilization and providing continuous fertilization for the plant. The top of the upper low-hydrophilic rock wool layer 5 has a water guide groove 7 and is fixedly connected to a layered connecting rib 8.

[0031] Working principle: When using this hydrophilic rock wool composite for planting, the base 1 first provides overall support. The biodegradable protective outer layer 2 and the inner protective layer 10 together form an outer protection to prevent rock wool fibers from scattering and being contaminated by the outside world. Then, the upper low-hydrophilic rock wool layer 5 and the lower low-hydrophilic rock wool layer 3 are connected by layered reinforcing bars 8 to maintain structural stability. At the same time, glass fiber support columns 4 are inserted between the two layers to prevent the rock wool layers from being compressed by pressure and to maintain the porosity and breathability. When water and fertilizer are supplied, water is evenly distributed through the water guide channel 7. The upper low-hydrophilic rock wool layer 5 slows down water evaporation, while the lower low-hydrophilic rock wool layer 3 absorbs and stores water. Excess water is discharged along the water guide channel 7 to avoid water accumulation. The hemispherical slow-release nutrient beads 6 and slow-release nutrient core balls 9 diffuse with the water, slowly releasing customized nutrients to continuously provide nutrition for the plant roots.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 utility model should be included within the protection scope of the present utility model.
