Equipped with discharge outlet 8.The height of barricade is higher than matrix 30cm.Matrix surface layer is laid with vegetable layer, and vegetable layer is by Alocasia ordora A, crinum asiaticum B
It is formed with emerald green tri- kinds of plant mixed plantings of Lu Li C；Alocasia ordora, crinum asiaticum and kingfisher Lu Li are planted in respectively in non-woven fabrics planting bag 3, plantation
Bag is laid immediately in matrix, paving mode such as Fig. 2, and Alocasia ordora and crinum asiaticum are alternately planted, and in phase by horizontally-arranged and vertical setting of types
Intersection region plantation kingfisher Lu Li between adjacent sea taro and adjacent crinum asiaticum.
The building method of strand vertical current constructed wetland provided by the utility model：
1) plant cultivation：The plant of vertical-flow wetland need to carry out slow seedling in advance；
Method is as follows：
Matrix is configured：The discarded raw oyster shell of seafood market or the generation of Sheng Hao processing factories is made full use of, without rinsing, directly
It crushes, making grain size, obtained raw oyster shell slag carries out decomposed in 15mm or so；The mud of attachment black and odorous water is acquired, is added in
The deadwood broad-leaved (after crushing, grain size is in 15mm or so) generated during gardens pruning, mix decomposed；Acquire sea sand and mistake
The sieve of 15mm；Raw oyster shell slag, mud, garden mould and sea sand are according to 2:3~5:3~5:3~5 ratio is configured.
Planting：Buy Alocasia ordora (thick 30mm of stem or so), crinum asiaticum (thick 30mm of stem or so), emerald green Lu Li (plant height 20cm
Left and right) and non-woven fabrics planting bag, interim Alocasia ordora and crinum asiaticum planted with the non-woven fabrics planting bag of bore 30cm, each bag plants 2
~3, emerald green Lu Li is planted with the non-woven fabrics planting bag that bore is 10cm, each 1~2, bag.
2) Production Zones Suitable is chosen
It is required that artificial swamp elevation is more than local mean sea level line, salinity is less than 20 ‰ during inwelling.
3), site preparation
It levels land, removes the sundries in weeds and upper soll layer, to obtain the level ground bed of one piece of suitable for plant growth.Level land
Tilling depth should be in more than 30cm, so that plant takes root growth.
Vertical-flow wetland matrix bottom is filled using rubble or cobblestone, is filled parallel with sea level to surface；
It is laid with again using coarse grain gravel and raw oyster shell slag, thickness is laid with non-woven fabrics on surface in 30cm or so, and prevention fine sand is lost in；
Then the sandstone of relatively fine particle, thickness 30cm or so are laid with, is finally laid with surface layer, is laid with using the non-woven bag for having planted seedling,
After the arrangement of plant is as shown in Fig. 2, be laid with, one layer of cobblestone can be laid on planting soil surface layer, to reduce flow to table soil
Wash away.Barricade barricade is built in matrix side to pour for mixed mud, highly higher than stromal thickness about 30cm, barricade and rubble or
The position of person's cobblestone connection, sets osculum, facilitates water outlet, each layout layer figure setting such as Fig. 1.
4) drainage ditch is built
Growing area terrain and tide flow direction are observed, plans the trend in gutter.According to the area scale of growing area, if
Put width, depth and the quantity in gutter.Antiseepage film used for aquiculture is laid in ditch.
5), standardized planting
Implantation time selects in winter or spring, to choose that specification is consistent, well-grown non-woven bag seedling is planted as possible
It plants.It if non-woven bag seedling, can also take bare-root seeding, carry out live matrix configuration.Piecemeal is planted, and Alocasia ordora, kingfisher Lu Li are suitable
Close piece plant or avenue system, crinum asiaticum both can piece plant, avenue system, also can isolated planting interspersed as decorative flower.
6) conventional maintenance
Routinely park maintenance level carries out pipe and supports, and maintenance and watering can be reduced after the success of plant slow seedling.Three kinds of plants
Old leaf yellow leaf only need to be wiped out.
