Abstract
The invention belongs to field of plant growing technology, and in particular to a kind of cultural method for improving Bruguiera conjugata tree transplanted survival rate.The cultural method provided by the invention for improving Bruguiera conjugata tree transplanted survival rate is that ripe Bruguiera conjugata plumular axis is put in homemade Nutrition Soil to cultivate to seedling, then it is transplanted in seedbed and cultivates to seedlings, seedlings bag cultivates a period of time after cutting lateral root, you can carries transplanting afforestation.The Bruguiera conjugata treelet plant height that the cultural method of raising Bruguiera conjugata tree transplanted survival rate provided by the invention is cultivated is used as 1.6m~1.8m; hat width reaches 50cm~80cm; transplanting survival rate is up to more than 96%; good salt tolerance; can be in light beach or difficult growing plants on beach afforestation; can give full play to Bruguiera conjugata shore protection disappear wave, mitigation combats a natural disaster, optimizes the multi-functional such as coastal environments, biometric safeguard diversity.
Description
Technical field
The invention belongs to field of plant growing technology, and in particular to a kind of cultivation side for improving Bruguiera conjugata tree transplanted survival rate
Method.
Background technology
Mangrove is to be grown in the torrid zone, subtropical zone seashore intertidal zone, and the woody plant community, xylium flooded periodically is soaked by seawater, its
With unique morphosis and function adaptability, such as form prop root, various forms of pneumathodiums, have many viviparous seedling with
And xeromorphy and salt resistance adaptation etc..Bruguiera conjugata is the main arbor mangrove of the South China coastal, is usually grown on Zhong Tan tops extremely
Interior beach, its flourishing root system can be not only that plant firmly stands on sandy beach, but also pneumathodium can be utilized to absorb in air
Oxygen, improve water body in appearance oxygen, and then improve water body self-purification capacity；The water surface can stablize silt again when declining, and have stream
The effect that water pulls, is the material circulation for maintaining Salt marsh ecosystem, manufactures the important element of good ecoscape.
At present, due to the sharp increase of population in the world, per capita cultivated land's resource is fewer and fewer, and agricultural production is faced with huge pressure
Power.In order to solve food problem, cultivation, deforestation cultivation, Development of Marine economy and mangrove competition beach are enclosed and cultivated on a large scale
The intensification of contradictions of painting.On the one hand deforestation cultivation causes Cultivated water nutrient laden, water hypoxia, destroy ecological environment；Mangrove face
Long-pending reduction threatens marine safety；Another aspect aquaculture products quality declines, and yield reduces, and triggers food-safety problem.
Recent studies find, mangrove multi-stage ecological system to the nutriments such as N, P in environment, heavy metal and petroleum hydrocarbon etc. have compared with
High catharsis.Therefore, construction mangrove has the function that marine ecology and raising aquaculture production important.
Patent document CN104488656A discloses a kind of structure of antipollution mangrove shelter-forest and builds method, described
Method is：It is more than 50% 1~2 year seedling mangrove thing to standard municipal sewage removal rate according to municipal sewage standard application
Kind, the mangrove species are the one or more in Bruguiera conjugata, Aegiceras corniculatum, Bruguiera conjugata, Avicennia marina, Rhizophora stylosa；It is dirty in offshore
Contaminate the annular pagatpat life in 1 year of wide 15~20 meters of plantation structure or drawing on non-beach suitable for afforestation more serious, that stormy waves is big and close wood 2 years
Raw seedling forest belt；Vacant lot plantation is red in wide 15~20 meters of endless belts of offshore after after pagatpat or drawing the wooden seed of forest in pass to plant 2~3 years
Tree plant species；Pagatpat or the spacing in the rows for drawing pass wood plantation are 1~2m, line-spacing is 1~2m；The spacing in the rows of mangrove plantation of one's native land
It is 0.5~1m for 0.5~1m, line-spacing.This method can build mangrove on non-beach suitable for afforestation more serious, that stormy waves is big is polluted
Woods, not only can plant denizen while also build autochthon mangrove, and landscape ecological is coordinated, species diversity enriches.
Then, above-mentioned mangrove shelter-forest builds time length, cumbersome, and as in mangrove family it is important into
The survival rate of member's Bruguiera conjugata is relatively low, has seriously affected the Afforestation Achievements of mangrove.Therefore, how to improve the survival rate of Bruguiera conjugata sapling is
Continue the problem solved at present.
Patent document CN102948355A discloses a kind of potting technology for mangrove forest seedling cultivation, the pot culture technology bag
Include：1) nursery is selected, selects the shale Climacteric symptoms that stormy waves is small, salinity is low, has water supply；2) nutritional bag, is seeking
Support in bag and seedling medium is housed, nutrient bag direct nursery is used to viviparous class mangrove plant；3) bag seedling turns basin, by step 2) side
Method cultivates 0.5~1 year bag after seedling, grows into seedling, which is transplanted in plastic seeding culturing basin and carries out big seedling cultivation；4) it is potted plant
The cultivation of seedlings, plastics, which educate to be placed in nursery lot after basin, in small transplantation of seedlings carries out big seedling cultivation, during big seedling cultivation plus
Strong water and fertilizer management, pruning and the prevention and control of plant diseases, pest control；5) seedlings go out garden, and the seedling of step 4) transplanting educated in basin again in plastics
After growth 1~2 year, mangrove seedlings are cultivated into.The seedlings cultivated using the cultivation technique, have stem's degree of lignification
High, the features such as root system is completely dense, compared with mangrove seedling, seedlings are stronger to the adaptability in the severe habitat of difficult beach.
Patent document CN103703978A discloses a kind of side that Canarium album fruit seedling plantation mangrove is fixed using white clay
Method, comprises the following steps：Raw material is chosen；The white clay of selection is built after mechanical deep processing to piece into bulk, among every white clay block
Perforation 2~3, by 2/3 depth in Canarium album fruit insertion white clay hole, reserves 1/3 Canarium album fruit and sees that light is breathed freely；By environmentally friendly nursery plastic bottle
Mud is filled, is sealed with the white clay of gained, 2~3 Canarium album fruits is fixed into Canarium album fruit with white clay piece；The Canarium album that white clay piece is fixed
Fruit or environmental protection bottle are overlayed in beach earth's surface.Mangrove is planted using this method, is not easy to be washed away by big wave；Between sapling and sapling
Relatively intensive, the rarefaction of air of distance, promotes the excessive end of the branch in sapling lower part and relies on the parasite of sapling existence because lacking sky
Gas is automatically dead；The end of the branch of sapling lower part is less, may advantageously facilitate tree trunk energy and concentrates to Growth In Space, is adapted to extensive people
Work is cultivated, and is also helped and is promoted coastal protecting forest-system to develop towards the compound sustainable direction of the ecological economy.
However, the cultural method of current Bruguiera conjugata is there are the defects of Bruguiera conjugata transplanting survival rate is low, and the cultivating large seedling time is long, nothing
Method adapts to planting requirement of the mangrove transplanting afforestation to Bruguiera conjugata.
The content of the invention
In order to overcome in the prior art Bruguiera conjugata cultivation technique there are the defects of.It is an object of the invention to provide one kind to improve
The cultural method of Bruguiera conjugata tree transplanted survival rate, to solve drawbacks described above.
