Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the drawings, but the scope of protection of the present invention is not limited in any way by the embodiments.
Example 1
A wind wave and salt resistant plant ecological floating bed suitable for river mouths is shown in figures 1-3 and comprises a planting plate, a fixing strip 1, a frame 2, a fixing body and a pendant, wherein the planting plate is made of light materials, planting holes are formed in the planting plate, and the planting holes are through holes perpendicular to the planting plate; the fixed body is used for the centre gripping planting seedling, and the centre gripping has the fixed body of planting the seedling to fill in planting downtheholely, is equipped with half hole of seedling on the fixed strip, and half hole of seedling on two fixed plates is fixed a seedling together, and the frame is fixed in the outside of planting the board, and the pendant setting is in the below of frame. Four angles reuse of frame puts an oblique batten 3 to one side fixed, simultaneously and add a horizontal batten 4 in the intermediate position of frame, fixed with T font steel sheet, increase the firmness. Two holes are arranged on the fixing strips at two sides of the horizontal wood strip and used for penetrating the rope system below the floating bed and connecting a heavy object.
The fixing strips are made of thin wood plates, semicircular holes with the diameter smaller than 2cm are formed in one side of each fixing strip, a circular hole is formed in each fixing strip of the two plates oppositely, the upper side of each fixing strip penetrates through a planted salt-tolerant emergent aquatic plant, and the lower layer of each fixing strip penetrates through the root of the salt-tolerant emergent aquatic plant.
The planting plate is made of polyethylene foam materials. Planting holes (with the aperture of 2.8 cm) are arranged on the planting plate at certain intervals for planting seedlings of salt-tolerant emergent aquatic plants, sponges with the diameter of 3.2cm are respectively arranged as fixing bodies, and a gap is reserved from the center to the edge of each sponge, so that the seedlings can be clamped and fixed on the planting plate.
The frame is made of Korean pine wood strips. The upper and lower fixing strips are fixed from both ends. The pendant is hung from 4 corners by four 1-meter ropes, is combined at the center position and then fixed and is connected with a heavy object. Meanwhile, a nylon rope with the diameter of 10mm penetrates through the two holes 6 on the two sides of the horizontal wood strip and is connected with the seabed heavy object. So as to lower the center of gravity and avoid being overturned by sea waves.
Example 2
The embodiment is a method for planting salicornia bigelovii by using the floating bed in embodiment 1, and the method comprises the following specific steps:
seedling collection: a shovel is used for collecting well-grown froggrass seedlings from a river beach, and the damage to roots is reduced as much as possible in the collecting and transporting process.
Planting: removing root soil of the collected salicornia seed seedlings, clamping plant bases by using a sponge fixing body, plugging the plant bases into holes of a planting plate, forming a fixing hole with the diameter smaller than that of the fixing body by using wood fixing strips in a pairwise opposite mode on the planting plate, enabling main stems of the planted seedlings in the fixing hole to be just opposite, clamping a row of planted seedlings by using the fixing strips in a pairwise opposite mode, fixing the periphery of the planting plate by using a frame after planting is finished, and pressing the fixing strips in the frame. Four angles reuse of frame puts a stuff to one side fixedly, simultaneously and add a horizontal stuff in the intermediate position of frame, fixed with T font steel sheet 5, increase the firmness.
Temporary culture: firstly, putting the fixed salicornia bigelovii into water with the salinity of 10 and the nutrient salt added, temporarily culturing for about one week, observing that white new fibrous roots grow out at the roots, then gradually increasing the salinity until the salinity is increased to 25 degrees every week, and enabling the salicornia bigelovii to gradually adapt to the high-salinity growth environment.
Laying: the temporarily cultured salicornia bigelovii is placed into a estuary sea area with salinity of 26-27, and the pendant is hung around the frame to reduce the gravity center and avoid being overturned by sea waves. Meanwhile, a nylon rope with the diameter of 10mm penetrates through two holes 6 on two sides of the floating bed cross wood strip to be connected with the seabed heavy object.
In the control group 1, the fixed froggrass and suaeda salsa seedlings were directly distributed in the estuary area.
The contrast group 2 is prepared by distributing fixed Salicornia Bigelivii seedling with salinity of 10, temporarily culturing in water containing nutritive salt for about one week, observing the growth of white new fibrous root at root, and directly culturing in river mouth with salinity of 26-27.
After 20 days, the survival rate of the salicornia bigelovii with the salinity gradually increased by temporarily culturing the salicornia bigelovii with low salinity water reaches over 80 percent, new branches and leaves grow at the top of the plant, while the survival rate of the directly distributed control group 1 is only 20 percent, the survival rate of the control group 2 is 61 percent (figure 4) and the plant does not grow obviously.
During the whole cultivation period, the ecological floating bed is not turned over by wind waves, and plants and the fixed bodies do not fall off from the planting plates.
