In take root growth, and moisture and nutrient can be absorbed from matrix and water bed, and then can preferably realize that tobacco seedlings are cultivated.
However, tobacco floating seed rearing method of the prior art is by seedlings nursing plate hole size due to being limited, tobacco seedlings that
Spacing is too small between this, the competition for mutually fighting for light, temperature, fertilizer, gas in growth course be present, this will certainly cause part tobacco seedlings
Growing way is bad, turns into weak seedling.Although existing float seedling method has substantially increased tobacco seedlings emergence rate and planting percent, strong sprout
Rate and later stage transplant the not high phenomenon of tobacco seedlings survival rate also generally existing.
To improve strong sprout rate, the method that prior art generally uses is to carry out multiple cutting seedlings to the tobacco seedlings in same seedlings nursing plate
Processing, control seedlings, promote seedling；For the principle of leaf-cutting depending on tobacco seedlings entirety growing way, seedlings heavy pruning, medium tobacco seedlings cut half, seedling
Do not cut；1/2 to the 1/3 of the tobacco leaf area is typically cut off during leaf-cutting, it is necessary to control its partial blade leaf-cutting face of the larger tobacco seedlings of seedling
Product is no more than 2/3；Every trimming in 4~6 days once.Cutting seedlings process is needed according to the growing states of tobacco seedlings, cutting seedlings difficulty and
Human factor is bigger, careless slightly, is just likely to cause tobacco seedlings the damage that can not be made up, so as to cause tobacco seedlings strong sprout rate
Low, the later stage transplants the defects of tobacco seedlings survival rate is not high, and repeatedly thinning can also increase disease spread risk to a certain degree.
The content of the invention
Solve tobacco floating seed rearing of the prior art, due to the growth competition between tobacco seedlings, and cause seedling weak seedling to produce
It is more, the uneven phenomenon of tobacco seedlings growing way is transplanted under film.A plant film is pulled out it is an object of the invention to provide a kind of tobacco floating seed rearing to move down

Canopy epiphragma.
4th, seedling management
First, rich water quality management.The water requirement for preparing nutrient solution strictly uses well water or running water.Fertilising is 75% for the first time
Go out full stand seedling stage, water per ton adds tobacco seedling fertilizer lkg；Nutrient solution can not be splashed in tobacco seedlings when adding fertilizer, and in seedling pond, uniform design is several
Place applies simultaneously, and water level cannot be below 5cm in pond, should add water to 8~10cm when insufficient in time.Second plus fertilizer should in 3 leaf phases,
Water per ton adds nursery fertilizer 0.67kg, and application process is applied fertilizer identical with first time.
Second, epidemic disaster management.Strict Insulation should be taken from during being seeded into emergence, to obtain maximum emergence
Rate, improve Phase ofsprouting.Hygrothermograph is suspended on the middle position in hut stage casing, and suspension height is preceding away from nursery card for emergence
At 4~5cm, after emergence away from 4~5cm of tobacco seedlings top at, 10 points of every morning and at 16 points in afternoon reading twice.On germination period floating plate
Temperature control, then should be aeration-cooling such as more than 30 degrees Celsius at 28 degrees Celsius at 5~10cm, in order to avoid hyperthermal injury bud, when warm in canopy
Degree should be noted that pass canopy is warming when being less than 20 degrees Celsius, administrative staff are documented to humiture and operation requirement daily.From going out
Seedling is to the cross phase still based on insulation, and temperature should remain 25~30 degrees Celsius at 5~10cm on disk, but in fine day noon temperature
In the case of height, ventilation dewetting, supplements carbon dioxide, strengthens photosynthesis, prevents pest and disease damage from occurring and hyperthermal injury seedling, ventilation
Time can not be long.From cross phase to seedling, to avoid based on extreme temperature, paying special attention to divulge information with the rise of temperature, canopy
Interior temperature prevents burn seedlings no more than 30 degrees Celsius.Relative humidity requirement in canopy.The main original that seedbed is fallen ill when humidity is too high
Cause, forbid greenhouse stuffy for a long time.Fine day combination greenhouse takes off film ventilation dewetting, based on temperature adjusting, continuous rainy days one
As temperature it is relatively low, may be selected noon appropriate ventilation dewetting.Sowing to neat seedling stage keeps 85% or so, and the small cross phase is maintained at 75%
Left and right, grand cross phase are maintained at 55~70%.When humidity is less than normal, extension is closed the film time, reduces ventilation number；When humidity is bigger than normal
When, increase ventilation number, extend ventilation time.
Third, disease control management.Because nursery temperature of shed, humidity are higher, tobacco seedlings children is tender, when applying various medicaments
It must avoid in fine day noon medication, and suitably reduce drug concentration, avoid causing serious poisoning, cause whole canopy tobacco seedlings withered
Extremely.Before the small cross phase, it can be endangered with 1000 times of metalaxyl-mn-zn liquid foliar spray 1 time with preventing samping off and damping-off
Evil, sick seedling is rejected in time while spray, take off film ventilation.Small cross phase, the main generation for preventing tobacco root rot and card
The growth of algae, prevented by strengthening taking off film, ventilation dewetting and shining bed measure.The grand cross phase, mainly prevent tobacco virus.The
3 days before leaf-cutting, the chemical control of agricultural chemicals or the recommendation of Tobacco company is supplied with set meal.The grand cross phase into seedling stage,
Main prevention tobacco virus, anthracnose, the chemical control of agricultural chemicals or the recommendation of Tobacco company is supplied with set meal, for the second time
3 days before leaf-cutting, foliage-spray prevents virus diseases agent 1 time.Before tobacco seedlings transplanting, tobacco seedlings are sprayed with 300 times of liquid blade faces sprays of Dong Wang antivirus
The generation of 1 prevention crop field mosaic disease of mist, ensures the transplanting of disease-free tobacco seedlings.
Fourth, thinning final singling management.During floating seedlings, morbidity tobacco seedlings have been periodically checked whether, general 3~5 days
Check once.Once it was found that diseased plant will remove immediately, focus on.When seedling grows to the small cross phase, fine day is selected as far as possible, is started
Thinning, final singling, tobacco seedlings unnecessary in seedling cave are taken out, while mend to plant on hole and be short of seedling.When filling the gaps with seedlings, with pincet or other works
Tool gently takes out tobacco seedlings from matrix, is transplanted in the disk cave for needing to fill the gaps with seedlings, and ensures per the seedling of cave one.When carrying out thinning, use
Suds is washed one's hands, and is reduced contact and is passed malicious, place cleaning immediately after the completion of operations.
Fifth, leaf-cutting.General 1~2 time of leaf-cutting is transplanted under film.Before leaf-cutting, diseased plant appearance is checked for, finds diseased plant
Or doubtful diseased plant, to remove in time.When the leaf of tobacco seedlings five wholeheartedly or tobacco seedlings largely start to erect, mutually connect when taking, shading, open
Beginning leaf-cutting, trim that area is no more than SL A every time 50%, main function is " suppression promote greatly small, stay centre ", every 5~7
It is cut once, and cutting range is to cut the 1/3 of maximum blade away from 3~4cm of seedling growing point, first leaf-cutting, cuts off maximum leaf later
The 1/2 of piece, lobus cardiacus must not be damaged every time, can not excessive leaf-cutting, otherwise tobacco seedlings can turn to be yellow.Tobacco seedlings will be dried during leaf-cutting, best
Carried out afternoon in fine day, should thoroughly be cleaned after leaf shearing machine before to seedling growth greenhouse group's leaf-cutting and pull down blade in 10% bleaching powder dilution
Or 2% 100~150 times of dilutions of chlorine dioxide thimerosal in soak more than 3 minutes, clean blade with clean water after immersion,
A pond seedling has often been cut during leaf-cutting to want reasonable arrangement leaf-cutting to blade spraying disinfection, the inadequate place of leaf shearing machine with thimerosal.
Also root is suitably cut while leaf-cutting, the tobacco seedlings residuum after leaf-cutting and invalid strain are concentrated outside canopy and disinfected.
Sixth, hardening.7~15 days before transplanting, tobacco seedlings intermittent is cut off the water supply, and suitably opens epiphragma, strengthens ventilation, illumination,
External environment is adapted in advance, and wilting occurs with noon tobacco seedlings, can revert to the standard of hardening sooner or later.
Seventh, strong seedling cultivation after seedling.After seedling growth and development is the seedling that can transplant (strong sprout, its middle finger stem is high by 6~
10cm, 1~2cm of stem girth, there are 4~5 functional leafs, leaf-cutting number 1~2 time, hardening is no less than 10 days, the seedling age cigarette of 60~70 days
Seedling), it can be transplanted by the strong sprout preferentially pulled out away in seed plate, allow remaining weak tobacco seedlings to be grown 3~5 days in Miao Chizhong, keep suitable
It is suitable for into the temperature and humidity of seedling stage seedling growth and development, transplanting is pulled out away again after weak seedling grows up to strong sprout, is strengthened so as to improve tobacco seedlings
Seedling output capacity.
