Description

Technical Field

[0001] The invention relates to the technical field of garden engineering, and in particular to a soil improvement brick and a preparation method and application thereof. Background Art

[0002] In garden construction projects, soil improvement plays a vital role in creating a good growth environment for garden plants and improving the survival rate and growth quality of plants. Existing soil improvement methods mainly include chemical improvement, soil replacement, biological improvement, physical improvement, application of organic fertilizers and the use of improvers. Although these methods can effectively improve soil quality in some specific cases, there are still many problems in practical applications, especially for soil improvement of planted trees and plants at different growth stages, the existing technology often cannot meet the needs.

[0003] Currently commonly used soil improvement technologies, such as large-scale excavation and application of chemical fertilizers, are suitable for large-scale improvement after the land is cleared and leveled, but there are many limitations for soil improvement of planted trees. First of all, improper soil improvement methods for planted trees, especially large-scale excavation, will not only cause great damage to the root system of trees, but may also affect the growth and stability of trees, causing tree death or slow growth. In addition, excavation is costly and has limited improvement effects on non-fast-growing tree species.

[0004] For the restoration of large trees, the current soil improvement method requires professionals to perform excavation, soil treatment, fertilizer preparation and other operations. Due to high technical requirements, high labor intensity and high labor costs, this soil improvement method cannot be widely used in large-scale garden construction, has low promotion value, and cannot meet the needs of rapidly developing garden construction. Summary of the invention

[0005] The purpose of the present invention is to provide a soil improvement brick and a preparation method and application thereof, which can effectively improve soil quality without destroying the root system of existing trees.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0007] A first aspect of the present invention provides a soil improvement brick, comprising:

[0008] A brick body, wherein a plurality of through holes are formed on the brick body;

[0009] The coating preparation is provided inside some of the through holes, and the coating preparation is used to release substances beneficial to plant growth into the soil.

[0010] Furthermore, the soil improvement bricks include the following matrix in terms of mass percentage: 25-35% coconut bran, 25-35% peat soil, and 30-50% humus soil.

[0011] Furthermore, the soil improvement brick also includes the following components: 4-7% perlite.

[0012] Furthermore, the coated preparation comprises a slow-release coating, and the interior of the slow-release coating is injected with one or a mixture of plant growth regulators, beneficial bacteria, bactericides, and insecticides.

[0013] The second aspect of the present invention provides a preparation method for preparing the soil improvement brick, comprising the following steps:

[0014] S1, mixing the three substrates of coconut husk, peat soil and humus soil in proportion and disinfecting them;

[0015] S2, adding the sterilized perlite to the three substrates and stirring to form raw soil;

[0016] S3, placing the raw soil into the mold of the soil improvement brick for stamping and forming, and punching out the through hole to form a brick body;

[0017] S4, extruding the coated preparation into the through hole.

[0018] Furthermore, after S3, the brick body is dried.

[0019] Furthermore, after S4, the soil improvement bricks are packaged with aluminum-plastic composite films, and the packaging of the soil improvement bricks is marked and coded with the corresponding information of the coating preparation ingredients.

[0020] The third aspect of the present invention provides an application, in which the soil improvement brick is applied. After the soil improvement brick is placed on the soil, coconut bran is filled in the through hole and above the coating preparation, and then the coconut bran above the coating preparation is pressed, and the pressing and filling are repeated until the coconut bran above the coating preparation is flush with the upper end surface of the soil improvement brick; the remaining through holes that do not contain the coating preparation are repeatedly filled with coconut bran and repeatedly pressed until the pressed coconut bran is flush with the upper end surface of the soil improvement brick.

[0021] Compared with the prior art, the soil improvement brick, preparation method and application of the embodiment of the present invention have the following beneficial effects: the coating preparation can continuously release substances that are beneficial to plant growth in the soil by encapsulating these beneficial substances, ensuring that the plants can continuously obtain necessary nutrients and regulatory substances for a long time, thereby improving the survival rate and growth quality of the plants; using soil improvement bricks to replace traditional excavation, fertilization, and addition of improvers can greatly reduce labor costs and construction difficulty. In addition, it also avoids the problem of frequent replenishment of fertilizers and improvers, thereby reducing maintenance and management costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] In the description of the present invention, the terms "upper", "lower", "left", "right", "front", "rear", "inner", "outer", "lateral", "longitudinal" and the like used to indicate the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only used to facilitate the description of the present invention and simplify the description, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. For those of ordinary skill in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0027] In the description of the present invention, the terms "provided with", "set", "connected", and "placed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.

[0029] The technical solution of the present invention is further described below in conjunction with embodiments and drawings.

[0030] like Figure 1-2 As shown, a first aspect of an embodiment of the present invention provides a soil improvement brick, comprising:

[0031] A brick body 1, wherein a plurality of through holes 101 are formed on the brick body 1;

[0032] Coated preparation 2: some through holes 101 are provided with coated preparation 2 inside, and the coated preparation 2 is used to release substances beneficial to plant growth into the soil.

[0033] Based on the above technical solution, the coating preparation 2 can continuously release substances that are beneficial to plant growth in the soil by encapsulating these beneficial substances, ensuring that plants can continue to obtain necessary nutrients and regulatory substances for a long time, thereby improving the survival rate and growth quality of plants; using soil improvement bricks to replace traditional excavation, fertilization, and addition of improvers can greatly reduce labor costs and construction difficulty. In addition, it also avoids the problem of frequent replenishment of fertilizers and improvers, thereby reducing maintenance and management costs.

[0034] Preferably, the soil improvement brick comprises the following matrix in terms of mass percentage: 25-35% coconut bran, 25-35% peat soil, and 30-50% humus soil.

[0035] Coconut bran has good permeability and a certain water retention capacity, which can effectively improve the air circulation of the soil, so that the roots can get sufficient oxygen supply and prevent the soil from becoming compacted; the addition of peat soil can further enhance the water retention of the soil; humus soil, as the main source of organic matter, is rich in a variety of nutrients necessary for plants, such as nitrogen, phosphorus, potassium, trace elements, etc. Humus soil is rich in organic matter, which is a food source for microorganisms, can promote the reproduction and activity of soil microorganisms, and can improve soil fertility; coconut bran and peat soil provide a breathable and moist environment for the growth of plant roots and the reproduction of microorganisms, which is more conducive to ensuring the biological activity of the soil and improving the growth efficiency and quality of plants.

[0036] More preferably, the soil improvement brick further comprises the following components: 4-7% perlite.

[0037] Perlite has a porous structure, which can effectively improve the air permeability of soil improvement bricks, allowing air to penetrate into the soil more easily, thereby providing sufficient oxygen to the plant roots and promoting the healthy development of the roots; in a humid environment, the porous structure of perlite can maintain moderate humidity without draining all the water into the soil, avoiding root rot caused by excessive soil moisture.

[0038] Preferably, the coating preparation 2 comprises a slow-release coating, and the interior of the slow-release coating is injected with one or a mixture of plant growth regulators, beneficial bacteria, fungicides, and insecticides.

[0039] Specifically, the preparation of the film-coated preparation 2 is as follows:

[0040] A cotton non-woven fabric is selected as the base layer, and then the polyamide is heated and melted and sprayed on the upper and lower end surfaces of the cotton non-woven fabric in a mesh-like staggered manner through a micro nozzle to form two layers of semi-permeable membranes with cotton non-woven fabrics spaced apart from each other. A corresponding mold is used for hot stamping according to the size of the through hole 101 to press out a sustained-release coating. During the hot stamping, an opening is made at the polyamide layer at the upper end of the sustained-release coating. After the sustained-release coating is cooled, a mixture of one or more plant growth regulators, beneficial bacteria, bactericides, and insecticides is injected into the sustained-release coating to penetrate into the cotton non-woven fabric, and then the sustained-release coating is sealed with an ultrasonic sealing machine.

[0041] A second aspect of an embodiment of the present invention provides a preparation method for preparing soil improvement bricks, comprising the following steps:

[0042] S1, mixing coconut husk, peat soil and humus soil in proportion and sterilizing under high pressure and high temperature;

[0043] S2, adding the sterilized perlite to the three substrates and stirring to form raw soil;

[0044] S3, placing the raw soil into a mold of a soil improvement brick for stamping and forming, and punching out a through hole 101 to form a brick body 1;

[0045] S4, extruding the film-coated preparation 2 into the through hole 101.

[0046] It should be noted that, since the sustained-release coating of the coated preparation 2 has a certain elasticity, after the coated preparation 2 is squeezed into the through hole 101 , it is difficult for the coated preparation 2 to fall out of the through hole 101 without external force interference along the axial direction of the through hole 101 .

[0047] The preparation method of soil improvement bricks is simple to operate, and mixing, stamping and extruding into through holes 101 are all basic industrial production methods. Soil improvement bricks can be produced in large quantities and efficiently in an assembly line manner, which greatly improves production efficiency, makes products more consistent, and also helps to reduce the cost per unit, making soil improvement bricks more competitive in the market and able to be widely used and promoted.

[0048] More preferably, after S3, the brick body 1 is dried.

[0049] The drying process helps to remove excess water from the brick body 1, reduce the water content, and maintain the ideal structural strength of the soil improvement brick in the final product. A proper drying process can ensure the dryness and stability of the brick body 1 after forming, thereby improving its compression resistance and durability, improving its actual application performance in garden construction, and reducing the breakage rate of the product.

[0050] More preferably, after S4, the finished soil improvement bricks are packaged with aluminum-plastic composite films, and the packaging of the soil improvement bricks is marked and coded with the corresponding ingredient information of the coating preparation 2.

[0051] The aluminum-plastic composite film packaging can effectively protect the soil improvement bricks from the influence of the external environment. The aluminum-plastic composite film has good air barrier, moisture resistance and moisture resistance, and can effectively prevent moisture, dust or other harmful substances in the air from entering the packaging, thereby ensuring the dryness and quality of the soil improvement bricks, and ensuring their stability and effectiveness before use; the packaging of the soil improvement bricks is marked and coded with the corresponding information of the coating preparation 2 ingredients, so that consumers can clearly understand the various nutrients, plant growth regulators, fungicides, pesticides and other ingredients contained in the coating preparation 2. Soil improvement bricks with different ingredients can be selected according to the growth conditions of trees, so that the soil improvement bricks can be disassembled and used immediately.

[0052] The third aspect of the embodiment of the present invention provides an application for soil improvement bricks. After the soil improvement bricks are placed on the soil, coconut bran is filled in the through hole 101 and above the coating preparation 2, and then the coconut bran above the coating preparation 2 is pressed and filled repeatedly until the coconut bran above the coating preparation 2 is flush with the upper end surface of the soil improvement brick; the remaining through holes 101 that do not contain the coating preparation 2 are repeatedly filled with coconut bran and repeatedly pressed until the pressed coconut bran is flush with the upper end surface of the soil improvement brick.

[0053] Coconut bran is used to fill the top of the coating preparation 2. The coconut bran serves as a buffer to avoid direct pressure on the coating preparation 2, which may easily cause the coating preparation 2 to rupture. The filling of coconut bran can also prevent the coating preparation 2 from being directly exposed to the air, which may cause the coating preparation 2 to rupture during long-term use. The coating preparation 2 is repeatedly pressed and filled until the coconut bran above the coating preparation 2 is flush with the upper end surface of the soil improvement brick, ensuring that the lower end of the coating preparation 2 is in contact with the soil, which can release nutrients to the soil evenly and stably, improve the soil structure, and meet the growth needs of plants. The application is simple, and there is no need to dig and destroy the original soil, allowing the plants to continue to grow in the native environment without being affected by soil disturbance, thereby promoting their healthy development.

[0054] In summary, the embodiments of the present invention provide a soil improvement brick and a preparation method and application thereof, wherein the coated preparation 2 can continuously release substances that are beneficial to plant growth in the soil, thereby ensuring that plants can continuously obtain necessary nutrients and regulatory substances for a long period of time, thereby improving the survival rate and growth quality of plants; using soil improvement bricks to replace traditional excavation, fertilization, and addition of improvers can greatly reduce labor costs and construction difficulty. In addition, it also avoids the problem of frequent replenishment of fertilizers and improvers, thereby reducing maintenance and management costs.

[0055] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
