Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0035] To make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0036] In the prior art, after a large number of seedlings are planted on the land where sand prevention and control are required, in order to prevent the sandstorm from damaging the tree seedlings, only simple devices such as protective nets are used to block around the seedlings or outside the vegetation. If a large sandstorm occurs, losses will be caused. During irrigation, large equipment needs to be used multiple times to irrigate the planted seedlings. In case of abnormal high-temperature climate, the water loss is relatively fast, and the number of irrigation times will also increase.

[0037] In the related art, a seedling protection device is disclosed, which relates to the field of plant protection and includes: a water storage shell is provided on the top of the base, the upper half of which is a frustum-shaped structure, and the lower half is a cylindrical structure and the bottom is fixedly connected to the top of the base; a protection shell is provided inside the water storage shell, the upper half of which is a frustum-shaped structure, and the lower half is a cylindrical structure and passes through the cavity in the central part of the water storage shell, and the bottom is fixedly connected to the top of the base; a plurality of first filter meshes cover a plurality of first round holes and are arranged in a ring on the outer wall of the frustum-shaped structure of the upper half of the water storage shell; a plurality of second filter meshes cover a plurality of second round holes and are arranged in a ring on the outer wall of the frustum-shaped structure of the upper half of the protection shell. The utility model can protect seedlings from being damaged by wind and sand in the desert and store rainwater to irrigate the seedlings.

[0038] In the related art, a seedling protection device for desertification control is disclosed, belonging to the field of desertification control. A seedling protection device for desertification control includes a pair of shielding plates. Arc-shaped sheaths are fixedly connected to one end of each of the two shielding plates close to each other. A water storage tank is fixedly installed at the end of the shielding plate away from the arc-shaped sheath. A permeation tank matching the water storage tank is provided below the shielding plate. It can store a sufficient amount of water in the water storage tank by installing the water storage tank on the shielding plate, and the water permeates into the soil in the area where the seedlings are planted through the permeation tank, effectively ensuring the humidity of the soil during the initial growth stage of the seedlings, effectively avoiding the phenomenon that the seedlings die due to lack of water, improving the survival rate of the seedlings, and by arranging the permeation tank at the lower end of the shielding plate, the soil wetted by the permeation tank is shielded by the shielding plate, reducing the amount of water evaporated, and effectively supplying it for the seedlings to use.

[0039] In the above related art, although the supply of water is realized, it is usually supplied by means of permeation. For sandy soil, simple permeation supply cannot guarantee the water demand of seedlings. At the same time, irrigation with rainwater has unstable factors, and the existing device cannot stably support seedlings in sandy soil and cannot guarantee the stable growth of seedlings. Therefore, in view of the above problems, the present application proposes the following solutions:

[0040] Example 1: Refer to Figures 1-7 , the present invention provides a seedling protection device for vegetation in sandy soil, including:

[0043] A watering assembly, including a number of surface drip irrigation parts and a number of deep penetration parts. The surface drip irrigation parts are installed on the bottom plate 1 and are in limit contact with the connecting pieces for dripping water and fertilizer from the ground surface. The deep penetration parts are arranged in the connecting pieces for permeating water and fertilizer from underground;

[0044] The protection component includes a protection member and a support member. The support member is arranged on the inner wall of the main support frame 2 for supporting seedlings, and the protection member is arranged on the outer wall of the main support frame 2 for protecting the seedlings.

[0045] In an embodiment of the present application, during use, the bottom plate 1 is placed on the soil, and the connecting member penetrates through the bottom plate 1 and extends into the soil layer to ensure the overall stability of the device. Seedlings are supported in the main support frame 2 by the support member. At the same time, a part of the bottom end of the main support frame 2 is located in the soil, and the roots of the seedlings extend into the soil.

[0049] In an embodiment of the present application, by turning the knob 11 to drive the rotating rod 7 to rotate, the moving top blocks 8 at both ends are driven to move upward and downward respectively through the arranged double-threaded grooves, thereby controlling the two sides of the limit cone rods 9 to synchronously extend into the soil layer and improving the overall stability.
