Description
Technical field
The invention belongs to agriculture field, especially a kind of breeding method of eel grass seedling.
Background technology
Eel grass (Vallisneria natans) is the heavy water herbaceous plant of Hydrocharctaceae Vallisneria, finds to share 5 kinds now
Class, including eel grass, close tooth eel grass, thorn eel grass, Asian monsoon region and big eel grass, eel grass can give birth in the water body of many types in China
Deposit, there is wider tolerance range to water environment.Eel grass is often used for cultured fishes, shrimps and crab as food resource,
It is also commonly used for the Shui nationality in addition to view and admire, eel grass is one of primary producer in aquatic ecosystem, had as high submerged plant
Purification of water quality and the ability for slowing down Nutrient release, have allelopathy to algae, can suppress the growth and breeding of algae.
Lake, Reservoir Eutrophication problem are serious in recent years, form the Water Environment In Lakes using nitrogen and phosphorus pollution as essential characteristic
Problem, it is serious to concentrate on lake and reservoir eutrophication, and water and soil resources exploitation is excessive, and ecological water is largely tied up, river
Withered, wetlands degradation, the section for flowing through city are heavily contaminated, and bio-diversity is reduced, and aquatic ecosystem is seriously broken
It is bad.Water Ecological Recovery technology is a kind of improvement body eutrophication problem forefront technology at present, wherein utilizing submerged plant bitter
It is one of key content in such technology that grass, which carries out Water Ecological Recovery,.
In addition, as the improvement of people's living standards, amusement landscape water body demand be continuously increased, substantial amounts of man-made lake and
Small-scale Landscape Water Bodies are applied in landscape construction, usually through a large amount of planting aquatic plants, the method for building aquatic ecosystem, are come
Ensure that water quality is steady in a long-term, wherein eel grass is one of primary biological material.
The acquisition modes of eel grass material have at present directly obtains from river, lake, reservoir, culture pond, or by hibernaculum,
The mode indirect gain of seed, tissue cultures, for the artificial collection of the natural eel grass that can directly gather Jing Guo long-term extensive style,
Wild resource is largely exhausted at present；And eel grass tissue culture technique cycle length, operates to require high limitation there is cost height
Property.Progressively ripe, engineering successful case with aquatic ecological technology increases sharply, the increasingly increasing of Technique Popularizing demand,
Eel grass demand will be presented blowout and increase, and the Availability of eel grass resource will be unable to meet engineer applied in the future at present.
The content of the invention
For above-mentioned deficiency, the present invention is intended to provide a kind of breeding method for the eel grass seedling that cost is low, the cycle is short.
In order to realize above-mentioned technique effect, technical scheme provided by the invention is such：A kind of cultivation side of eel grass seedling
Method, comprise the following steps：
Arrange nursery field：The nursery field is made up of at least one seedbed, seedbed is dug into deep 9cm, soil block is smashed, every square
Rice seedbed adds 0.4 kilogram of fertile soil, stirs, seedbed is arranged smooth, water, control water depth degree are then added into nursery field
For 1.5cm, bleaching powder is added to the water and carried out disinfection, control every square metre of seedbed to add 8 grams of bleaching powder, disinfecting time 4 days；
Select seedling：Plant height 18cm eel grass is selected to be put into 8 points of kinds of immersion, the sterilization pool in sterilization pool as seedling
In thimerosal be mass fraction 1% liquor natrii hypochloritis；
Transplant seedling：By seedling transplanting on seedbed, every 4 plants of seedlings are a root and stem of certain plants, are 30cm per the line-spacing of the root and stem of certain plants, arrange away from for
30cm, it is 10cm to control the depth of water in seedbed, to seedbed on spray hormone combinations liquid, the amount of the hormone combinations liquid is every square metre of seedling
0.1 liter of bed spray, then the cover film on seedling, keeps 18 DEG C of water temperature in seedbed, the hormone combinations liquid is in every liter of water
The solution that the indole-3-acetic acid of the 6- benzyls aminoadenine and 10mg that add 18mg is formed；
Manage nursery field：The water temperature for controlling nursery field is 18 DEG C, and preceding 30 days seedbeds depth of water control of transplanting kind after seedling exists
10cm, depth of water control in seedbed is in 20cm after 30 days for transplanting seedling, control ph 6.8, when seedling is transplanted into nursery field 49 days, leads to
The new eel grass seedling for crossing subterranean stem formation will be long to 10 centimetres of plant height, and the eel grass seedling density in seedbed is 295 plants/square metre；
Remove seedling：The film being covered on eel grass seedling is removed, water is added into seedbed, the depth of water is reached 29cm, is kept
11 days, seedling is removed into nursery field, that is, obtains eel grass seedling.
The present invention has advantages below compared with conventional method：The present invention utilizes the division propagation and greenhouse of eel grass itself
Eel grass seedling is cultivated in nursery field, and energy amount reproduction eel grass seedling, cost is low, and eel grass survival rate is high, and pollution is few, and insect pest is few, is adapted to big face
Product is promoted；The method of the present invention meets aquatic ecosystem structure, repaired, needed for the four seasons of regulation and control, has broken eel grass plantation
Season limit, overcome its tissue culture technique and have that cost is high, the cycle is long, operation requires the shortcomings of high, and optimized aquatic
The form of construction work of eel grass in state system engineering.
Embodiment
With reference to embodiment, the claim of the present invention is described in further detail, but not formed pair
Any restrictions of the present invention, any limited number of time modification made in the claims in the present invention protection domain, still the present invention's
