Description

Technical Field

[0001] The invention belongs to the technical field of seedling cultivation, and in particular relates to a mangrove plant seedling planting and cultivation device. Background Art

[0002] Mangroves are important wetland ecosystems distributed in the intertidal zones of tropical and subtropical coasts, with ecological functions such as wind and wave protection, carbon fixation and storage, water purification, and biodiversity maintenance. In recent years, with the advancement of mangrove ecological restoration projects, its seedling cultivation technology has become a key link in restoring the mangrove ecosystem.

[0003] In the existing mangrove seedling cultivation technology, in order to avoid the drift or dispersion of seedlings caused by natural factors such as tides, wind and waves, a dense planting mode is usually adopted in the seedling stage. Specifically, during seedling cultivation, the seedlings are planted at a high density in the seedbed or seedling container, and the ability of the seedling group to resist water flow impact is enhanced through the physical aggregation effect. However, during the growth of mangrove seedlings, their developed aerial roots and underground roots are entangled with each other due to the high planting density, forming an intricate root network, making it difficult to separate individual seedlings when lifting them. Forced separation can easily cause mechanical damage to the roots and reduce the survival rate of transplantation. Therefore, we proposed a mangrove plant seedling planting and cultivation device to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that when the existing cultivation device is used for seedling cultivation, due to the high planting density, the underground roots of the mangrove seedlings are entangled with each other, it is difficult to separate the individual seedlings when transplanting, and forced seedling separation can easily cause mechanical damage to the roots, thereby reducing the survival rate of transplantation.

[0048] A drainage pump 8 is fixedly installed on the support platform 1, and the input end of the drainage pump 8 is fixedly connected to a bent water inlet pipe 81. The end of the water inlet pipe 81 extends into the groove of the support platform 1. One end of the water inlet pipe 81 extends into the support platform 1 and is close to the bottom of the groove wall of the groove of the support platform 1. When water penetrates into the groove, water can be discharged to avoid water accumulation in the groove and the problem of waterlogging of the leaves of the seedlings.

[0049] The method of use of the present invention is as follows:

[0050] When in use, the mangrove plant seedlings are placed with their roots facing downward into the seedling tube 32, and then the branches of the seedlings are bound by the binding belt 64. At this time, the roots of the seedlings are located between the two semi-conical tubes 33, and the driving wheel 2 is controlled by the signal transceiver to work, and the support platform 1 is brought to an area suitable for the growth of mangrove seedlings;

[0051] After the supporting platform 1 reaches the specified position, the first motor 4 works, the threaded rod 41 rotates, and the movable plate 31 moves vertically downward under the limiting action of the limiting rod 42, and the cultivation tube 32 and the semi-conical tube 33 move downward accordingly, until the punching columns 333 at the lower ends of the two semi-conical tubes 33 are completely submerged in the underwater mud. At this time, the second motor 55 works, and the driving rod 54 drives the rotating rod 51 and the worm 52 to rotate through the bevel gear, so that the rotating disk 321 rotates, and the arc-shaped rack inside the annular groove 322 drives the fixed gear 332 to rotate, so that the two semi-conical tubes 33 rotate and unfold. When the semi-conical tubes 33 are unfolded, the movable ring 62 will be pulled downward by the pull rope 65 to squeeze the compression spring 61, and the movable ring 62 moves downward, and the pull rod 63 pulls the seedling downward through the binding belt 64, and the root of the seedling will enter the hole made by the punching column 333.

[0052] The first motor 4 continues to work, pushing the movable plate 31 and the cultivation tube 32 downward until the semi-conical tube 33 is completely immersed in the soil. At this time, the second motor 55 works in the opposite direction, so that the two semi-conical tubes 33 rotate and reset, and the roots of the seedlings and the soil at the roots can be wrapped inside to prevent the root system from being entangled during the growth of the seedlings, and enhance their ability to resist water flow impact. When the two semi-conical tubes 33 rotate and reset, the movable ring 62 returns under the elastic force of the compression spring 61, and the roots of the seedlings can be pulled upward to keep them in a vertical upward state, thereby ensuring the smooth growth of the mangrove plant seedlings;

[0053] When the seedlings grow to the point where they can be transplanted, the first motor 4 works in the reverse direction to drive the entire planting mechanism 3 to move upward, and the cultivation tube 32 and the two semi-conical tubes 33 can drive the roots of the seedlings and the soil at their roots upward together. During transplanting, the moisture and nutrients in the original soil can provide a short-term buffer for the seedlings, helping them to gradually adapt to the new environment. The entire movable plate 31 together with the cultivation tube 32 can be completely detached from the supporting platform 1, and the cultivation tube 32 can also be detached from the movable plate 31 alone, making transplanting more convenient.
