Abstract

The invention discloses a cultivation method of flue-cured tobacco small strong seedlings. The cultivation method is finished by the following steps of: (1), selecting a site, (2) manufacturing a compartment surface, (3) manufacturing a seedling growing shed, (4) paving a film and injecting water, (5) manufacturing a seedling growing disc, (6) feeding into the disc and sowing seeds, (8) covering a film, (9) managing temperature and humidity, (10) shearing leaves, (11) airing the disc and domesticating, (12) preventing and treating plant diseases and insect pests, (13) reaching small strong seedling standards and (14) preparing before transplanting. According to the cultivation method disclosed by the invention, the air temperature at a seedling growing stage of one part of a tobacco-growing area is too low so that the current situation suitable for transplanting tobacco seedlings of tobacco lands and the like at a transplanting stage is achieved; compared with the existing seedling growing manner, a seedling growing period is shortened; the problem that the difficulty of cultivating common strong seedlings is great, caused by weather reasons, can be solved; and the small strong seedlings are suitable for a flue-cured tobacco film or a well cellar type transplanting manner. Compared with the existing seedling growing manner, the links of conventional float seedling growing including a plurality of times of leaf shearing are reduced, so that the labor is reduced and the cost is reduced. The times for shearing the leaves are reduced and the occurring of diseases is reduced.

Description

The little strong seedling cultivation method of flue-cured tobacco
Technical field
The present invention relates to a kind of little strong seedling cultivation method of flue-cured tobacco, belong to Flue-cured Tobacco seedling technical field.
Background technology
The cigarette seeding cultivating method of under also not having special flue-cured tobacco film at present or well cellar for storing things formula transplanting method.It is short and strong that two kinds of transplanting methods all require to transplant cigarette seedling, the process employs the seedling-cultivating tray that aperture is less, both decreased the consumption of matrix, economized on resources, protection of the environment, and when being beneficial to again seedling, root system wraps up matrix completely, is easy to get seedling; Enrich paclobutrazol in the grand cross phase simultaneously, solve cigarette height of seedling but not strong problem; Method adopts the mode of booth cover hut epiphragma more in addition, solves low temperature in seedling stage, the problem such as slow of emerging.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of little strong seedling cultivation method of flue-cured tobacco be suitable for under flue-cured tobacco film or well cellar for storing things formula transplanting method, can overcome the deficiencies in the prior art.
Technical scheme of the present invention is: flue-cured tobacco little strong seedling cultivation method is completed by following step:
(1), place election: select clean water quality, have abundant water resources, physical features is smooth, landform is open, irrigation and drainage are convenient, leeward, face south, not contaminated, be easy to management, traffic convenience, level land, hot measured region as nursery place;
(2), face, railway carriage or compartment makes: according to local circumstance, form is made into water bed to take to follow closely wooden a tree, used in making timber for boats, plank, lay bricks etc., and water bed ridge height is 8-10cm; Seedling growth greenhouse two stays 50cm to make sterilization pool, and 35cm is stayed on both sides, centre stays more than 40cm as management channels, stays 35cm to manage row between railway carriage or compartment and railway carriage or compartment;
(3), seedling growth greenhouse makes: take booth or middle canopy to overlap the mode of hut (ridge type), in booth or middle canopy, a ridge type hut is installed in face, each railway carriage or compartment.
(4), plastic film mulch water filling: the necessary whole thin leveling of bed surface, confirms without repaving water bed film after tip and hard object, surrounding compression, then water filling enters bed, depth of water 4-6cm, and water injection time is the first day of sabot sowing;
(5), seedling-cultivating tray makes: be made up of polystyrene foam plastics, specification is 68cm × 34cm × 6cm, hole count 200 hole or 288 holes;
(6), sabot is sowed: fluffy for matrix hand rubbing scattered again evenly loaded in disk hole, make matrix tamp hole, draw together flat with wood (bamboo) sheet, behind acupoint pressing plate pressure cave, namely available seeder is sowed, and seeding quantity controls at every hole 1-2 grain; Finish kind of rear wood (bamboo) sheet and draw together flat matrix lid kind, can put down gently and coil in water bed;
(7), epiphragma: covered again by floating plate with mulch film, film is from floating plate 2 ~ 3cm, and the compacting of mulch film surrounding, prevents moisture from evaporating too fast, take off film in time after sprouting;
(8), temperature and humidity management: sow to the seeding stage to be incubated management, it is aeration-cooling that temperature should take off film immediately higher than 30 DEG C; Emerge to the little cross phase based on controlled humidity management, the sense of dish humidity one finger touch matrix water stain-free is as the criterion; Little cross, to becoming seedling stage in case high temperature is main, will be taken off film when the outer temperature of fine day canopy is more than 16 DEG C and ventilate.
(9), rich water quality management: fertilization principle is that first time is sufficient, second time is sufficient, third time is few, and the grand cross phase enriches paclobutrazol, and spray amount drenches with cigarette seedling and matrix and is advisable; Duty looks into water level, and water level of guaranteeing to try to get to the heart of a matter is 1-1.5cm;
(10), leaf-cutting: only cut a leaf, carry out when cigarette seedling envelope dish, to blade straight snips about 1/2;
(11), dish hardening of drying in the air: because air humidity causes greatly soil humidity excessive after emerging, suitably dry in the air dish, and dried in the air dish every 3-5 days once, each 2-3 days, allows cigarette seedling grow under the environment of alternation of wetting and drying;
(12), the extermination of disease and insect pest: sprout term disease mainly to prevent virus diseases, stem rot, anthracnose; Insect pest is mainly to prevent snail, slug, aphid;
(13), little strong sprout standard: seedling age about 45 days, color is light green-green, stem girth 1.5-2cm, stem height 3-5cm, and number of sheets 5-6 sheet is got seedling matrix and do not fallen apart, and without damage by disease and insect, growth potential is strong, neat and consistent;
(14) prepare before, transplanting: must sell at reduced prices in afternoon on the previous day of transplanting suctions liquid manure into pond, can transplant.
compared with the prior art, the present invention has the following advantages:
1, because part cigarette district nursery stage temperature is on the low side, when causing arrival to be suitable for transplanting time, cigarette seedling can not meet transplanting requirement, waits the present situation of cigarette seedling with causing cigarette.The relatively existing seedling raising manners growing-seedling period of this method shortens, and solves and cultivates the large problem of routine difficulty in strong sprout because climate reasons causes, under being suitable for flue-cured tobacco film little strong sprout or well cellar for storing things formula transplanting method.
2, relatively existing seedling raising manners, decreases the link of the conventional floating seedlings such as repeatedly leaf-cutting, thus subtracts work and fall this.
3, decrease leaf-cutting number of times, reduce the generation of disease.
4, seedling-cultivating tray aperture is less, decreases the consumption of matrix, economize energy, protection of the environment; Also be easy to get seedling when transplanting simultaneously.
5, the mode of booth cover hut epiphragma again solves the Low Temperature Problems of nursery.
6, enrich paclobutrazol and promote that cigarette seedling reaches cross growth after certain stem height, improve seedling rate in strong sprout.
7, seedling age is shorter, is conducive to part cigarette district Reasonable adjustment transplanting time.
