[0021] It should be noted that all directional indications in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture. If this specific posture changes, the directional indications will also change accordingly.

[0022] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically and clearly defined.

[0023] In the present utility model, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and may be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0024] The present utility model provides a tea garden covering device, as Figure 1 and Figure 4 shown, which includes several covering plates 1 spliced alternately. One end of the covering plate 1 is provided with symmetric inclined surfaces 2. By fitting the inclined surfaces 2 on the covering plates 1 to each other, the covering plates 1 are spliced together. Notches 3 are formed at positions corresponding to the tea tree planting on the inclined surfaces 2. When the covering plates 1 are spliced together, the notches 3 are closed to form a planting hole 4 for wrapping the roots of the tea trees. In this embodiment, each complete planting hole 4 is formed by splicing three notches 3, and each notch 3 is one-third of a circle, so that a complete circle is formed after the notches 3 are spliced together.

[0025] Since the planting specifications of tea trees are generally single row with double plants, double row with double plants, or double row with single plant, the number and positions of the notches can be opened on the inclined surfaces 2 according to different situations. In this embodiment, a notch 3 is opened at the intersection of the symmetric inclined surfaces 2, and notches 3 are also opened at the roots of the two inclined surfaces.

[0026] By splicing the covering plates one by one on the tea garden land, the effect of covering the tea garden is achieved. At the same time, it can also enable the tea trees to grow smoothly, which is beneficial to controlling the growth of weeds, preventing soil erosion, maintaining soil humidity, and increasing soil biodiversity.

[0027] As Figure 1 , Figure 2 and Figure 5 shown, in order to make the splicing effect of the covering plates 1 better, slopes 5 are provided on both opposite sides of the inclined surface 2 on the covering plate 1. The slopes 5 on both sides are rotationally symmetric, that is, the inclination directions of the slopes 5 on both sides are parallel. Therefore, when splicing the covering plates 1, adjacent covering plates 1 are fitted through the slopes 5, making the splicing of each covering plate 1 more stable, not easily misaligned up and down, and having a better use effect.

[0028] As Figure 2 and Figure 5 shown, in order to ensure that the slopes 5 do not slide relative to each other during fitting, a limiting device is provided on the fitting slopes 5. In this embodiment, a long strip-shaped limiting groove 6 is provided on one slope of the covering plate 5, and a long strip-shaped convex block 7 is provided on the other slope. The convex block 7 cooperates with the limiting groove 6 on another covering plate 5, thereby restricting the fitting slopes 5 and making the connection between the spliced covering plates 1 more stable.

[0029] As Figure 2 and Figure 3 shown, in order to make the covering plate 1 more stable when placed on the land, a wavy surface 8 is provided on the side surface of the covering plate 1 in contact with the ground, increasing the friction with the ground, making the covering plate 1 more stable when placed on the ground and not sliding by itself.

[0030] In order to save costs, the material of the covering plate 1 can be made from tea bricks, and the tea leaves can go through the following several processes.

[0031] S1: Mechanically pick fresh leaves. Use a tea picking machine or a pruning machine. The tea leaves should be picked with a specification of no more than six leaves, and the fresh leaves should be spread out in the processing factory indoors.

[0032] S2: Sort branches. Manually sort the above-mentioned fresh leaves, remove the thicker branches, and directly fix the fresh leaves without spreading them out.

[0033] S3: Sprinkle water and fill with slurry. Except for rain leaves, dew leaves, and tender bud leaves, other grades of fresh leaves need to be "sprinkled with water and filled with slurry". It is required to sprinkle water while turning the fresh leaves to make the water evenly distributed on the fresh leaf blades. The amount of water sprinkled should be flexibly controlled according to the tenderness grade and season of the fresh leaves, generally 10% of the weight of the fresh leaves, and it is appropriate if there is no dripping water.

[0034] S4: Fixing-off the green, using a drum fixing-off machine or a steam fixing-off machine. The temperature of the drum fixing-off machine is set at (280 - 350) °C, turn off the air-blowing equipment of the fixing-off machine, adjust the feeding amount of leaves, so that the temperature at the outlet of the fixing-off machine reaches (80 - 90) °C, steam comes out, the fixing-off leaves become soft, and there are no scorched leaves as the appropriate degree;

[0035] S5: Hot rolling, it is required to roll the fixing-off leaves while they are still hot, the feeding amount of leaves is a natural full barrel, the pressure application follows the principle of "light - heavy", and it can be taken off the machine after the leaves are formed into strips;

[0036] S6: Initial drying, the rolled leaves are spread on an open ground, and natural conditions such as natural wind or sunlight are used to air-dry or sun-dry the fresh leaves until the water content reaches about 15%;

[0037] S7: Pressing, steam-soften the dried tea leaves with a water content of about 18% - 20%, and use tea pressing equipment such as tea bricks and tea cakes to press them into shape. The required thickness of the finished product is 1 cm - 3 cm, and it can be picked up without breaking or falling apart.

[0038] The pressed tea bricks can be covered on the ground, which not only saves costs but also can be reused.

[0039] It should be understood that the above description of the specific embodiments of the present invention is only for explaining the technical route and features of the present invention, and its purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. However, the present invention is not limited to the above specific implementation manners.
