Description

Technical Field

[0001] The utility model relates to the technical field of sea lettuce seedling raising equipment, in particular to a sea lettuce seedling raising device for sea lettuce experiments. Background Art

[0002] Sea lettuce is a rare and endangered wild plant that is unique to China and is under key protection. It can only grow in water bodies with clean water quality and high transparency, and is known as the "touchstone" of water quality. Sea lettuce is propagated by seeds, and is an important edible, medicinal and waterscape ornamental plant. At present, in order to study sea lettuce, researchers have introduced and domesticated wild sea lettuce, and planted it in containers of a certain height. During the planting process, the seeds of sea lettuce will naturally fall off and sink to the bottom of the water after maturity, and germinate into seedlings after a certain period of time. The depth of the planting container of sea lettuce is usually more than 1 meter. Due to the height limitation of the planting container, it is inconvenient to transplant the seedlings of sea lettuce, and the roots of the seedlings are easily intertwined with the roots of adult plants. When transplanting, the roots of the seedlings are easily damaged and die, which seriously affects the reproduction of sea lettuce. Therefore, after long-term efforts and explorations, we have continuously improved and developed a device dedicated to sea lettuce seedling cultivation. Utility Model Content

[0011] The above technical solution has the following advantages:

[0012] (1) When the utility model is used, the hanging ears of the frame are hung on the upper end of the side wall of the planting container, and then a small planting pot filled with planting soil is placed on the bottom plate, and then the floating body is placed in the frame. The floating body can rise and fall automatically according to the liquid level of the planting container. When raising seedlings, at least one thick flower branch is selected nearby, and the flower part of the flower branch is arranged to the through hole of the floating body. When the seeds of the flower are mature, they can fall off automatically and sink into the small planting pot to prepare for seedling raising.

[0013] (2) The utility model is convenient for seedling cultivation and can effectively protect the seedlings from damage during transplanting. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The specific implementation methods of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in each implementation method of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Example 1

[0024] As shown in the accompanying drawings, a seedling raising device for sea lettuce experiments includes a frame 2 with a hanging ear 1, and a floating body 3 located in the frame 2; the frame 2 includes a bottom plate 4, a frame opening 5 located above the bottom plate 4, and four side strips 6 connecting the frame opening 5 and the bottom plate 4; the hanging ear 1 is fixedly connected to the frame opening 5; the middle part of the floating body 3 has a through hole 7.

[0025] As a specific technical solution of this embodiment, the hanging ear 1 is in an inverted U shape. Obviously, it can also be in an inverted L shape or other applicable shapes.

[0026] In order to prevent the flowers of the sea lettuce from being effectively located at the through hole 7 of the floating body 3, a plurality of protrusions 8 are provided at the upper end of the floating body 3, and grooves are formed between the protrusions 8. The grooves are used for the flower stems to pass through, so as to achieve relative fixation of the flowers. When in use, a plurality of nearby strong flowers can be selected according to the situation, and the flower stems are placed in the grooves, and the flowers are located in the through hole 7. The protrusions 8 are preferably cylindrical, and obviously can also be in suitable shapes such as rectangular parallelepiped.

[0027] As a preferred technical solution of this embodiment, the frame 2 is cylindrical in shape, and the floating body 3 is annular, and other shapes can obviously be used. The frame 2 can be integrally formed of plastic, and the floating body 3 can be made of light foam material or a cavity structure to ensure that it can float on the liquid surface of the planting container.

[0028] As a preferred technical solution of this embodiment, the bottom plate 4 is a perforated plate or a grid plate to reduce its own weight.

[0029] Obviously, in this embodiment, the number of the side strips 6 can be increased or decreased reasonably, and they can be in suitable shapes such as cylindrical strips or flat strips.

[0030] Example 2

[0031] As shown in the attached drawings, a seedling raising device for sea lettuce experiments, wherein the hanging ear 1 is in an inverted 7 shape, and is made of a deformable material, such as plastic or rubber, and the inverted 7-shaped arrangement allows the upper portion to easily accommodate the reinforced turning of the mouth of the planting container, and the lower portion can be attached to the outer wall of the planting container to provide hanging stability. The rest is basically the same as in Example 1.

[0032] When the utility model is used, the hanging ears of the frame are hung on the upper end of the side wall of the planting container, the frame is located in the planting container, and then the small planting pot 9 filled with planting soil is placed on the bottom plate, and then the floating body is placed in the frame. The floating body can rise and fall automatically according to the liquid level of the planting container. When raising seedlings, at least one thick flower branch is selected nearby, and the flower part of the flower branch is arranged to the through hole of the floating body. When the seeds of the flower mature, they can fall off and sink into the small planting pot 9 by themselves, so as to realize the seed seedling preparation. After the seed shedding period is over, the small planting pot 9 can still be placed in the planting container through the frame 2 for seedling raising, or the small planting pot 9 can be taken out and a new planting container is used to sink the small planting pot to the bottom for seedling raising.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
