As shown in fig. 2 and 3, the plurality of insertion tubes 1 are connected by tube tubes, and the tube openings are flush, so that the planting surface 31 can be effectively utilized, and the planting efficiency is improved.

In practical application, the direction of the planting surface 31 is consistent with the main water flow direction of tidal flat flood tide.

It should be noted that the silt filled in the cannula 1 is flush with the top end of the cannula 1, or the top end of the silt is lower than the top end of the cannula 1. 1/3-2/3 of the lower end of the embryo inserted in the cannula 1 is inserted in the cannula 1.

The insertion tubes 1 in two adjacent rows are arranged in a staggered manner, and in practical application, the heights of the insertion tubes 1 in each row can be set to be the same, partially the same or different according to practical application scenes.

When seedling removal transplantation is needed, the inserting tube 1 can be further provided with a booster 2, as shown in fig. 4, silt is filled in the inserting tube 1, the booster 2 is provided with a push rod 21 and a push plate 22 arranged at the end part of the push rod 21 and used for seedling removal when the red saplings are taken out of the garden, the red saplings can be transplanted without the inserting tube 1 by arranging the booster 2, the push plate 22 is matched with the inner diameter of the inserting tube 1, so that when the push plate 22 is pushed by applying force to the push rod 21 to move from one end to the other end of the inserting tube 1, the silt in the inserting tube 1 can be pushed out, the seedling removal operation of the red saplings is realized, and the red saplings which are removed can be bundled and transported to a destination for planting.

Specifically, the outer diameter of the push plate 22 is smaller than the inner diameter of the cannula 1 so that the push plate 22 can move freely in the cannula 1. The end of the push rod 21 is connected with the push plate 22 in a detachable or integrated manner.

Specifically, the embryos of mangrove plants are sown in the insertion tubes 1 of the tidal flat to limit the roots to grow in a spread mode towards the periphery and to be staggered, so that the purpose of not damaging the roots during seedling lifting is achieved, and the purposes of improving the quality of seedlings and improving the working efficiency are achieved.

The tidal flat is a seedling raising base selected from a tidal flat of a medium and high tide bay with flat terrain, convenient traffic and relatively weak hydrodynamic force, a planting surface 31 is arranged according to the main current direction of the flood tide, and a pedestrian passage and a transportation passage are planned, so that the main current direction of the flood tide is consistent with the length direction of the planting surface 31.

Finished pipes with proper pipe diameters are selected as the insertion pipes 1 according to the types of the produced plants, and for the types of mangroves with large plant size and developed root systems, the pipes with larger pipe diameters are selected as the insertion pipes 1, and the cutting length is longer.

Example 2:

this embodiment is a preferred embodiment of embodiment 1.

In the embodiment, kandelia candel is taken as an example for production, a PVC pipe of DN110 is taken as an insertion pipe 1, the PVC pipe is cut into lengths of 0.5cm per section, the prepared insertion pipe 1 is inserted into a tidal flat, the insertion depth is determined by the local tide level and the flooding resistant duration of the selected plant type, the pipe orifice at the top end of the insertion pipe 1 is kept flush as far as possible, and the flooding time of the upper end of the insertion pipe 1 is ensured to be less than 6 h. Two adjacent insertion tubes 1 can be connected by tube so as to improve the utilization rate of the beach land.

For the convenience of later maintenance management, the insertion tubes 1 can be inserted into the planting surfaces 31 in a row-by-row manner, each planting surface 31 is 1.1m wide, for example 10 tubes, and 30m long, for example 300 tubes, 0.3m is left between two adjacent planting surfaces 31 to serve as a pedestrian passageway, 4 planting surfaces are 1 planting unit 3, and 1.5m is left between two adjacent planting units 3 to serve as a transportation passageway.

The in-situ sand is taken to fill the cannula 1, and when the planting surface 31 is required to be higher than the local tidal flat, the in-situ sand can be collected and filled into the cannula 1 to be flush with the pipe orifice.

When the embryos are inserted, 2/3 of the lower ends of the embryos are inserted into the insertion tubes 1 for maintenance and management, whether the embryos washed away by the tidal water exist or not is observed in the first few days, and if yes, the embryos are timely replenished; the askew embryos are timely strengthened. During the cultivation process, the growing and development conditions of the seedlings are observed, whether diseases and insect pests occur or not is observed, and the diseases and the insect pests are prevented and controlled in time. And transplanting the cannula 1 and the red tree seedlings to a beach below the high level integrally when the seedlings reach the outplanting standard, so as to realize the beach below the high level.

It should be noted that the length of the cut pipe of the initial inserting pipe 1 is determined according to the tidal flat height and the tidal level of the selected manually planted mangrove forest, the top of the pipe after inserting is slightly higher than the lowest height of the mangrove plant growth, and the height of the exposed beach surface of the pipe is preferably less than about 1/3 of the total length of the pipe.

Determining the planting elevation and determining the planting density, as shown in fig. 6, the planting is carried out in a delta-shaped arrangement in the embodiment, the spacing is 0.5m, the front row and the rear row are staggered, and 3-7 rows are preferably planted.
