Description

Technical Field

[0001] This application relates to the technical field of agricultural seedling raising, and particularly to a degradable seedling raising pot and a preparation method thereof. Background Art

[0002] In agricultural and forestry production, it is usually necessary to first raise seedlings through a seedling tray and then transplant them. When the existing vegetable and flue-cured tobacco transplanting machines in our country are working, seedlings are taken manually and then transplanted through a series of transmission devices.

[0003] Common seedling taking methods include manual seedling taking and mechanical seedling taking. During the seedling transplanting process, degradable seedling raising pots are usually used and pressed into the soil to save the use of transplanting devices. However, the traditional seedling raising pots are not strong enough, which easily causes damage to the pot body during seedling transplantation, resulting in damage to the seedlings. Summary of the Invention

[0004] To solve or partially solve the problems existing in the related art, this application provides a degradable seedling raising pot.

[0005] To achieve the above object, this application is implemented through the following technical solutions:

[0006] A degradable seedling raising pot, the degradable seedling raising pot includes:

[0007] A pot body;

[0008] A number of bionic convex hulls, provided on the inner wall of the pot body;

[0009] Among them, the pot body is formed by combining a waterproof film made of grease and a degradable layer made of biological materials. The waterproof film uses the hydrophobic molecular structure and low surface tension characteristics of grease to avoid water penetration. The bionic convex hulls reduce the actual contact area between water and the inner wall of the pot body to reduce water adsorption, so that the pot body remains dry during seedling raising and transplantation.

[0010] Indentations are provided on the side wall of the pot body along its height direction.

[0011] A number of ventilation holes arranged in a linear array are opened on the indentations.

[0012] Leakage holes are opened at the bottom of the pot body.

[0013] The ventilation holes and leakage holes outside the pot body are covered with a waterproof film.

[0014] A handle is provided at the upper end of the pot body.

[0015] The biological material is waste paper, straw, bagasse or coffee grounds.

[0016] The grease is vegetable grease or animal grease.

[0017] A preparation method of a degradable seedling-raising pot, comprising the following steps:

[0018] S1, crushing the biological material and soaking it until it becomes mushy, and obtaining biological material pulp after precipitation;

[0019] S2, using a mold to press the biological material pulp into a pot body with a thickness ≥ 1 mm;

[0020] S3, naturally drying the pot body in the air, and immersing the dried pot body entirely in grease to form a waterproof film, and the immersion time is one second;

[0021] S4, drying the pot body again to obtain the finished product.

[0022] Advantages of the present application: In the present application, through the action of the bionic convex hull and the waterproof film, it is prevented that water enters the pot body during seedling raising and seedling transplanting, resulting in a decrease in its strength and stiffness, ensuring that the pot body remains dry during seedling raising and transplanting, thereby ensuring that the pot body has a relatively high strength, and further avoiding damage to the seedlings during the seedling transplanting process.

[0023] The pot body of the present application is composed of fermented degradable substances. When the pot body enters the soil, it will degrade, thereby realizing the normal use of the seedling-raising pot during seedling raising, and it can be directly transplanted as a hole-pressing device during transplanting. After transplanting, with the growth of plants, it degrades, which is an environmentally friendly production process and avoids soil pollution.

[0024] In the present application, indentations and ventilation holes are provided on the pot body, so that after the pot body enters the soil, the root system of the seedlings will expand the indentations. The ventilation holes on the traditional seedling-raising pot are usually fine and have a small pore diameter. Compared with the traditional seedling-raising pot, the pore diameter of the ventilation holes 2 in the present application is set larger. In this way, it is more convenient for the soil to contact the root system of the seedlings through the ventilation holes, enabling the root system of the seedlings to grow rapidly towards the soil, thereby facilitating the pot body to be expanded and broken, and facilitating the rapid infiltration of water. Furthermore, after transplanting, the seedling-raising pot does not hinder the growth of the root system, maintains the integrity of the root system, and can also be rapidly degraded.

[0038] In order to make the purpose, technical solutions and beneficial effects of this application clearer, the preferred embodiments of this application will be described in detail below in conjunction with the drawings to facilitate understanding by those skilled in the art.

[0039] Embodiment 1:

[0040] See Figure 1 , a degradable seedling raising pot, the degradable seedling raising pot comprising:

[0041] A pot body 1;

[0042] A number of bionic convex hulls 5, provided on the inner wall of the pot body 1;

[0043] Among them, the pot body 1 is composed of a waterproof film 7 made of grease and a degradable layer 8 made of biological materials. The waterproof film 7 utilizes the hydrophobic molecular structure and low surface tension characteristics of grease to avoid water penetration. The bionic convex hull 5 reduces the actual contact area between water and the inner wall of the pot body 1 to reduce water adsorption, so that the pot body 1 remains dry during the seedling raising and transplanting processes.

[0044] Specifically, the outer shape of the pot body 1 is the same as the inner cavity of the existing seedling tray (available in the market). The pot body 1 has an inverted pyramid structure with an open upper end to facilitate the entry of soil, seeds, etc. The degradable layer 8 of the pot body 1 is made of biological materials, making it easy to degrade after entering the soil. The waterproof film 7 is made of grease. The grease molecules are mainly long-chain non-polar hydrocarbon chains, and the proportion of polar groups (such as hydroxyl groups and ester groups) is extremely low. This structure makes it impossible to form hydrogen bonds with water molecules, resulting in difficulty in the spreading of water on the surface of the grease. The surface tension of the grease is much lower than that of water. According to the capillary penetration formula, the penetration height of a liquid in a material is proportional to the surface tension. Therefore, using grease for the waterproof film 7 can significantly inhibit the penetration of water. A number of bionic convex hulls 5 are provided on the inner wall of the pot body 1. The surface of the bionic convex hull 5 has protrusions, enabling water to only contact the tips of the convex hulls. The contact angle of water on the surface of the convex hull can reach more than 150°, forming bead-like rolling and reducing retention. At the same time, the gaps between the convex hulls store air, forming a hydrophobic barrier.

[0045] In the traditional seedling transplanting process, degradable seedling pots are usually used and pressed into the soil to eliminate the use of transplanting tools. However, the strength of traditional degradable seedling pots is usually small, easily causing damage to the pot body during seedling transplantation, thus causing damage to the seedlings. In this application, through the action of the bionic convex hull 5 and the waterproof film 7, water is prevented from entering the pot body 1 during seedling raising and transplanting, which causes its strength and stiffness to become smaller, ensuring that the pot body 1 remains dry during the seedling raising and transplanting processes, thereby ensuring that the pot body 1 has a high strength and further avoiding damage to the seedlings during the transplanting process.

[0046] In addition, in this application, the pot body 1 is composed of fermented degradable substances. When the pot body 1 enters the soil, it will degrade, thus realizing the normal use of the seedling pot during seedling raising, directly transplanting as a hole pressing tool during transplantation, and an environmentally friendly production process of degradation as the plant grows after transplantation, avoiding soil pollution.

[0047] Embodiment 2:

[0048] See Figures 1 to 3 Based on Embodiment 1, indentations 3 are provided on the side wall of the pot body 1 along its height direction.

[0049] A number of air holes 2 arranged in a linear array are opened on the indentations 3.

[0050] A water leakage hole 6 is opened at the bottom of the pot body 1.

[0051] The air holes 2 and the water leakage holes 6 outside the bowl body 1 are covered with a waterproof membrane 7 .

[0052] A handle 4 is provided at the upper end of the bowl body 1 .

[0053] Specifically, a handle 4 is processed at the upper end of the pot body 1 to facilitate picking up or placing by a robot or other clamping device; a leakage hole 6 is processed at the same position as the leakage hole in the plug tray at the bottom of the pot body 1; an indentation 3 is processed at an appropriate position around the pot body, and the thickness at the indentation 3 is thinner than that of a normal pot body; at the same time, an air hole 2 is also opened along the indentation 3, and the indentation 3 and the air hole 2 are provided to ensure normal growth of the root system after transplantation.

[0054] The working process is as follows: the seedling pot is used in conjunction with a plug tray. In the early stage of seedling cultivation, the seedling pot is placed in the inner hole of the plug tray by a manipulator or manually, and the substrate, sowing, and covering with soil are performed according to the normal seedling cultivation process; at this time, since there is a layer of waterproof film 7 on the outside of the pot body 1 (including the air vents 2 and the water leakage holes 6), the pot body is dry and maintains a certain strength; when the seedlings are transplanted, a manipulator or other clamping device can be used to clamp the handle 4, and the pot body 1 itself can be used as a hole presser to directly press the pot body 1 with the seedlings into the field. At this time, since the soil contacts the seedling roots through the air vents 2, the seedling roots will quickly grow into the soil, and the root system will expand during the growth process. When the roots expand to a certain extent, the pot body 1 will be stretched open from the indentation 3, and the pot body 1 will rupture; since the waterproof film 7 is damaged at the rupture, moisture will penetrate into the pot body 1, and the pot body 1 is usually composed of fermented degradable substances, which will degrade rapidly if moisture penetrates.

[0055] In the present embodiment, an indentation 3 and air holes 2 are provided on the pot body 1 so that the seedling roots will expand the indentation 3 after the pot body 1 is buried in the soil. The air holes 2 on the traditional seedling pot are usually fine and small in diameter. Compared with the traditional seedling pot, the air holes 2 of the present application are set larger in diameter. In this way, it is more convenient for the soil to contact the seedling roots through the air holes 2, so that the seedling roots can grow quickly into the soil, which is conducive to the pot body 1 being expanded and broken, and facilitating the rapid infiltration of water, thereby achieving the goal that the seedling pot does not hinder the growth of the root system after transplantation, maintains the integrity of the root system, and can also be quickly degraded.

[0056] Embodiment three:

[0057] Based on the above embodiment, optionally, the biomaterial is waste paper, straw, bagasse or coffee grounds.

[0058] Specifically, waste paper, straw, bagasse or coffee grounds are easy to degrade and will not pollute the soil after degradation; straw contains nitrogen, phosphorus and potassium, and coffee grounds contain nitrogen, which continuously release nutrients during degradation, reducing the use of chemical fertilizers, turning waste into treasure, saving energy and protecting the environment, and reducing carbon emissions.

[0059] Optionally, the oil is vegetable oil or animal oil.

[0060] Specifically, while vegetable oils or animal fats have excellent waterproof properties, their degradation products are fatty acids and glycerol, with no microplastic residues; animal fats contain natural sterols, and vegetable oils contain vitamin E, which promote root growth and increase soil organic matter when degraded.

[0061] Example 4:

[0062] A method for preparing a degradable seedling-raising pot, comprising the following steps:

[0063] S1, crushing the biological material and soaking it until it becomes mushy, and obtaining biological material pulp after precipitation;

[0064] S2, using a mold to press the biological material pulp into a pot body with a thickness ≥ 1 mm;

[0065] S3, naturally drying the pot body in the sun, and immersing the dried pot body entirely in oil to form a waterproof film, and the immersion time is one second;

[0066] S4, drying the pot body again to obtain the finished product.

[0067] Specifically, the pot body 1 can use other existing degradable materials, such as straw, bagasse or coffee grounds, etc., and the waterproof film 7 uses vegetable oil or animal fat. Its preparation method (taking the pot body 1 as waste paper and the waterproof film 7 as vegetable oil as an example) is as follows:

[0068] Crush the waste paper, soak it until it becomes mushy, precipitate to obtain pulp, and use a mold (including a handle 4, ventilation holes 2, water leakage holes 6 and bionic convex hulls 5) to press it into the pot body 1; the thickness of the pot body 1 is not less than 1 mm to ensure strength; after natural drying in the sun, immerse it entirely in liquid vegetable oil for 1 second, and the time cannot be too long, otherwise the waterproof film 7 will be too thick and affect the subsequent degradation time; take out the soaked pot body 1 and dry it again, and the finished product is obtained after drying.

[0069] In addition, the pot body 1 can also use other existing degradable materials, and it is necessary to re-conduct experiments to determine the thickness. The waterproof film 7 can also use natural degradable materials such as rosin and paraffin, and its thickness needs to be determined through experiments.

[0070] It should be noted that the structures and / or installation methods not elaborated in this application can be known to those skilled in the art by combining common general knowledge and / or existing technologies, and are not the key points of disclosure in this application, so no further elaboration will be made here.

[0071] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present application and not to limit them. Although the present application has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and details without departing from the scope defined by the claims of the present application; the dimensions of the drawings have nothing to do with the specific physical objects, and the physical object dimensions can be arbitrarily changed.
