Description
Technical Field
The utility model relates to the field of mangrove forest planting devices. More specifically, the utility model relates to a planting device suitable for mangrove forests in coastal watercourses.
Background
Mangrove forest mainly grows on the tropical and subtropical coast and in the estuary intertidal zone, and because mangrove forest is immersed by periodical river and sea water, a unique intertidal growth environment is formed. The mangrove forest has important functions in preventing water loss, purifying water, resisting wind and wave, promoting silt and protecting dike, protecting biological diversity, etc.
In recent years, with the accelerated process of urbanization, the construction of coastal and coastal river projects, reclamation, over-fishing, mining and excavation and the like cause serious damage to the ecological environment of coasts and estuary intertidal zones, and the water and soil loss of the coasts and estuary intertidal zones is accelerated. The problem is solved in the engineering at present mainly through constructing ecological bank protection in the bank edge region in intertidal zone, and ecological bank protection utilizes the flourishing root system of mangrove to carry out the bank protection and consolidate soil, prevents the soil erosion in tidal zone. And the mangrove forest seedlings are directly planted in the coast or the intertidal zone of the river mouth, sediment deposition of the substrate is obstructed due to wind and wave scouring, and the planted saplings are washed down after the roots of the saplings are exposed due to loose substrate, so that the survival rate of the mangrove forest is low. Therefore, a planting device suitable for mangrove forests in coastal watercourses is needed, which can provide stable production environment for the mangrove forests and reduce the influence of wind waves on the growth of the mangrove forests.

Detailed Description
The present invention is further described in detail below with reference to the attached drawings so that those skilled in the art can implement the utility model by referring to the description text.
It is to be noted that the experimental methods described in the following embodiments are all conventional methods unless otherwise specified, and the reagents and materials described therein are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
As shown in fig. 1 to 2, the present invention provides a planting device suitable for mangrove forest in coastal river, comprising:
the slope protection bags 1 are placed on the side slopes of the coastal river channels in multiple rows; any slope protection bag 1 is filled with soil 3, and the upper surface of the slope protection bag 1 is provided with an opening 5 for planting mangrove forest 4;
and a slope protection stone 2 which is built at the lower part of the side slope.
In this kind of technical scheme, slope protection bag 1 selects the slope protection bag that the material is dacron and polypropylene fibre, the soil 3 that packs in slope protection bag 1 is local soil because mangrove is strong adaptability to local saline and alkaline soil to improve the survival rate of mangrove forest plant species. Before planting, firstly investigating the growth conditions of local mangrove such as plant density, plant height and the like, and selecting mangrove plant species with high growth rate, high survival rate and good water quality purification effect; the selected mangrove forest 4 is then planted in the opening 5 of the revetment sack 1 and the seedlings are compacted. Preferably, the mangrove forest 4 is selected from avicennia marina and tung tree, the two mangrove forest varieties have developed root systems and stronger water and soil conservation capability, the diversity and the number of the microbial communities of the plant root systems are higher than those of a non-root area, and the combined action of the microbes further enhances the water quality purification effect. And sufficient mud balls and side roots are required to be reserved in the mangrove forest 4 during seedling planting, the mud balls can be bound by new grass ropes, and some root-promoting agents can be applied if necessary, so that the root system can germinate as early as possible and grow rapidly, and the stabilizing effect of the slope protection bag 1 and the mangrove forest 4 is enhanced. The slope protection stones 2 are horizontally laid at the lower parts of the side slopes, the length of each slope protection stone 2 is larger than or equal to that of one row of the slope protection bags 1, and the upper end surfaces of the slope protection stones 2 are flush with the upper end surfaces of the slope protection bags 1 located at the lowest row. The slope protection stone 2 is used for preventing the cavity from appearing in the area of the slope protection bag 1 at the lower part of the side slope, which is contacted with water, due to water flow scouring. After the mangrove forest 4 is planted, the survival condition, the growth rate and the water quality change condition of the mangrove forest are monitored regularly, and the water and soil conservation condition in the intertidal zone is observed. And for the mangrove forest with poor local growth, timely replacing and reseeding.
In another embodiment, the revetment bag 1 has a rectangular shape with a length parallel to the bottom of the side slope. Namely, the slope protection bag 1 adopts a transverse code, and the outer side of the slope protection bag is smooth and smooth after stacking. Preferably, the size of the revetment bag 1 may be selected from 40 x 80 cm.
In another embodiment, the upper surface of the slope protection bag 1 is provided with two openings, and the distance between every two adjacent openings is 30-40 cm. So as to improve the planting density of the mangrove 4 and ensure the growth space of each mangrove.
In another embodiment, the distance between two adjacent slope protection bags in each row of the slope protection bags 1 is 3-5 cm. Plant in the bank protection bag 1 need carry out the compaction to soil behind the mangrove 4, consequently adjacent two bank protection bag 1 interval certain distance can ensure adjacent two behind the compaction soil bank protection bag 1 can end to do not produce the overlap joint.
In another embodiment, after the mangrove forest 4 is planted in the slope protection bag 1, the filling thickness of the soil 3 in the slope protection bag is 14-16 cm. After the mangrove forest 4 is planted in the slope protection bag 1, soil needs to be tamped, and the thickness of the soil 3 in the slope protection bag is kept at 14-16cm after tamping.
In another embodiment, the slope has a slope of less than 20 degrees. When the slope of side slope is too big, be located one row last slope protection bag 1 will be to being located one row next under the action of gravity slope protection bag 1 causes the extrusion, thereby influences planting device is holistic stability.
