Description
Technical field
The present invention relates to tobacco cultivation technical fields, are specifically related to a kind of cigarette based on conversion film and external source addition NaHS
Careless seedling raising and strengthening method
Background technique
Currently, sun light green house concentration nursery is mainly carried out in the cultivation of tobacco seedlings in China's cured tobacco production, however it is southwestward
The flue-cured tobaccos main producing region such as Guizhou, Guangxi, Guangdong and Chongqing of Sichuan, southeastern Fujian, the nursery stage of flue-cured tobacco can be different degrees of by low
The warm few influence according to weather.Meanwhile plastic film and other Insulations make under originally overcast and rainy weather that illumination is tight in greenhouse
Weight is insufficient.Tobacco seedlings hypoevolutism is thereby resulted in, nursery stage is elongated, increased costs, and seedling quality difference has also seriously affected flue-cured tobacco
Yield and quality.
Influence of the light quality to root system development is to pass through auxin (IAA) in regulation plant after light receptor receives optical signal
Synthesis and distribution realize.It has been reported and shows H2Gaseous signal molecule of the S as IAA Downstream regulatory root system development, ginseng
Caused active oxygen (ROS) oxidative pressure under degeneration-resistant stress is formed and reduced with plant lateral roots, it can be seen that, H2This gas of S
Signaling molecule is in close relations during participating in light quality regulation plant root system development.
Therefore it provides one kind can shorten growing-seedling period, the seedling raising and strengthening method for promoting seedling quality is art technology
The technical issues of personnel's urgent need to resolve.
Summary of the invention
In view of this, the present invention provides a kind of tobacco seedling strong sprout method for adding NaHS based on conversion film and external source,
To reach shortening growing-seedling period, the effect of seedling quality is promoted.
To achieve the goals above, the present invention adopts the following technical scheme:
Tobacco seedling strong sprout method based on conversion film and addition NaHS, comprising the following steps:
(1) select hidding and sunny side, miniclimate is conducive to heat preservation, and topography is flat, close to the place of source of clean water establish seedling shed and in
Conversion film is laid in seedling shed；
(2) nursery pond is built in seedling shed, nursery pond is rectangle, and depth is 5cm~20cm；Nursery bottom of pond portion is smooth
After making real, after herbicide and insecticide spraying bottom of pond, with the black thin film shop fixtures of black 0.10mm~0.12mm；Then it adopts
With single cave volume about 27ml, single alms bowl is in inverted trapezoidal shape, and the polystyrene foam lattice disk of small hole at bottom part diameter 0.5cm~0.6cm is made
It is layed in nursery pond for seedlings nursing plate；
(3) seedling medium is laid in seedlings nursing plate, seedling medium is by peat, turf, carbonization or decomposed crop residues, leech
One or more of stone and fine perlite are made；
(4) vesicle of neat and consistent is extruded in the center in each seedling cave of seedlings nursing plate with acupoint pressing plate, then uses seeder)
1~2 capsuled seed of every bunch planting, depth of planting 2-5mm, rear screen cover about 1-3cm thickness matrix carry out nursery；
(5) after nursery 40-50 days, NaHS solution is added into nursery pond within every 7-12 days, so that NaHS in nursery pond
Concentration is 20-40nM's, to get finished product tobacco seedlings after amounting to addition 3-4 times.
Further, the conversion film in above-mentioned steps (1) is to turn blue light PO film and/or turn feux rouges PO film.
Further, it is above-mentioned turn blue light PO film be convert 400-500nm blue light for 300-400nm ultraviolet light turn blue light
PO film；Turn feux rouges PO film be convert 600-700nm feux rouges for 300-400nm ultraviolet light turn feux rouges PO film.
Further, in above-mentioned steps (1) conversion film with a thickness of 10, horizontal tensile strength is 35MPa or more, horizontal elongation
It is 600% or more, indulging tensile strength is 30MPa or more, and vertical elongation is 550% or more, light transmittance 88-100%, and mist degree is
15.5% or less.
It further, further include that drip agent is added to conversion film while carrying out nursery in above-mentioned steps (4) in conversion film canopy
And/or antifogging agent.
Further, drip agent described above is polyol fatty acid ester class or alkylolamides.
Above-mentioned polyol fatty acid ester class is preferably glycerin monostearate, D-sorbite liver fatty acid ester；Abovementioned alkyl
Alkylolamides is preferably coconut acid diethanolamide.
Further, antifogging agent described above is octyl phenol polyoxyethylene ether.
Be using above-mentioned further beneficial effect: addition polyol fatty acid ester class drip agent can make water 25
DEG C surface tension 25-30mN/m can be reduced to by 72mN/m, so as to be sufficiently spread out on PO film；Add octyl phenol polyoxy
Ethylene ethers antifogging agent can further decrease the surface tension of water to 15mN/m, so that moisture film is launched into thinner water layer, more
Ground is flowed to fastly, to improve the efficiency that water layer absorbs droplet.
Further, each nursery pond NaHS concentration is 20-40nM in above-mentioned steps (5).
Compared with prior art the beneficial technical effect of the present invention lies in: the present invention using the luminous energy of different wave length by plant
In specific light receptor perceived, regulate and control the seed sprouting of plant by the signal transmitting of a series of complex, root, stem, leaf
The principle of growth, present invention facilitates the root growth in plant seedling stage, main side root long, lateral root number, dry-matter accumulation amount are all excellent
In White-Light processing, tobacco root can be promoted to develop using method of the invention, especially had significantly to tobacco lateral root
Effect, also has certain castering action for the resistance of transplanting time tobacco seedlings.

Test example
Recording different disposal method of the present invention influences as a result, being shown in Table 1-3 seedling quality, and foreign aid's auxin in table 3 is
NAA (methyl α-naphthyl acetate).
1 different disposal seedling quality of table
As can be seen from Table 1, two kinds of conversion films obviously accelerate tobacco seedlings growing process and emergence, seedling time, transfer
The feux rouges canopy film processing tobacco seedlings seedling time is most short, shortens seedling raise period 6 days compared with normal film, and tobacco seedlings plant height, stem length, stem girth, life

Table 2 does not have to influence of the processing tobacco seedlings to nursery breeding time
| Processing | Sowing time | Seedling-growing time | The small cross phase | The grand cross phase | The seedling time |
| Common canopy film | January 28 | 12 days 2 months | 14 days 2 months | 21 days 2 months | April 18 |
| Turn feux rouges canopy film | January 28 | 9 days 2 months | 12 days 2 months | 18 days 2 months | April 12 |
| Turn blue light canopy film | January 28 | 9 days 2 months | 12 days 2 months | 18 days 2 months | April 14 |
Influence of 3 different disposal of table to seedling stage seedling quality
The biological character of tobacco seedlings seedling stage turns addition 20nM in feux rouges film canopy studies have shown that compared with other processing
NaHS and the NaHS processing for turning addition 20nM in blue Light Film canopy significantly improve the plant height of tobacco seedlings, wherein turn to add in feux rouges film canopy
Add the NaHS of 20nM to handle and significantly improve tobacco seedlings overground part and root biomass, and emergence rate is 100%.
