Description
Technical field
The present invention relates to tobacco seedling technical field, particularly relate to a kind of tobacco floating seed rearing method.
Background technology
Tobacco seedling is the important step in leaf tobacco production process.Under the background of China's tobacco monopoly system, tobacco planting carries out in strict accordance with the purchase of contract planting scheme, and tobacco planting belongs to multi-form agriculture and produces, it is easier to be subject to amblent air temperature impact, how to guarantee that the supply that tobacco seedling can be guaranteed both quality and quantity is always up the problem that tobacco business is paid much attention to.The quality of tobacco seedling quality directly determines the quantity of tobacco planting then, finally affects the number of acquisition and the quality of Nicotiana tabacum L..
At present, floating seedlings be China's tobacco seedling frequently with a kind of mode.According to statistics, tobacco floating seed rearing accounts for more than the 80% of the whole nation tobacco seedling gross area.Tobacco floating seed rearing has the advantages such as concentration is high, quantity is big, but there is also and need to improve and perfect place, such as problems such as seedbed phase disease spread risk controls.
The farming operation of seedbed phase is the main path that tobacco diseases is propagated, and how effectively to reduce seedbed phase disease spread probability and becomes the key issue that current leaf tobacco production nursery link necessarily solves.
The Relatively centralized of leaf tobacco production nursery, creates favorable conditions for disease spread, also challenges for seedbed management.Nursery centrostigma behavior adjustment management is not in place, causes that seedling raising process operation is lack of standardization, and environmental health condition is not good, using appliance sterilization is not thorough, all become the source point of cause of disease invasion nursery point, go out to infect offer condition for seedbed phase tobacco seedlings, for instance: nursery water source, operator's sterilization are thorough etc..
In tobacco seedling process, owing to tobacco seedlings seeding quality is not high, cause emerging uneven, hole or many, cave tobacco seedlings phenomenon occur, finally affect concordance and the seedling quality of tobacco seedling growth.Therefore, in practice process, (two panels true leaf is close with cotyledon size to need to reach the little cross phase in tobacco seedlings, intersect in crosswise) time, by manually taking out unnecessary Seedling, a Seedling is mended in hole, to guarantee every cave one Seedling, accomplish to go greatly little, prevent or cure a disease weak, make whole dish tobacco seedlings uniformity as far as possible.But, now tobacco seedlings is younger tender, it is easy to hinder Seedling, and manual operation adds disease spread probability.Between the Seedling mended need certain time to recover regrowth due to mechanically damaged so that the speed of growth is slower than the tobacco seedlings of normal Seeded growth, and ultimately resulting in the weak Seedling quantity of single-deck during seedling increases.It addition, for guaranteeing to have sufficient amount tobacco seedlings to fill the gaps with seedlings, often will at seeding time at single many seeds of bunch planting kind, this cigarette kind usage quantity increases, and during also adding seedbed, the recruitment cost of Seedling puts into.
Difference due to tobacco seedling growth speed, at tobacco seedling growth to after to a certain degree, grow tobacco seedlings faster easily slower tobacco seedlings to be caused and block, at present, how production carries out leaf-cutting operation when tobacco seedlings " closing disk takes shade " (when the 3rd true leaf of tobacco seedlings occurs), to reach to control tobacco seedling growth, promote tobacco seedlings resistance, regulation and control are for the Seedling time, the tobacco seedling growth do not cut is very fast, can cause that tobacco seedling growth is inconsistent, but now carry out leaf-cutting, not only mechanical difficulties, and easily fall to cutting, additionally, tobacco seedlings is too small, still have growing space, need repeatedly to carry out leaf-cutting, and increase seedbed phase leaf-cutting number of times, also fundamentally increase leaf-cutting and operate the disease spread probability brought.
Leaf-cutting operation be in current floating seedlings process frequently with a kind of technical measures, its Main Function has control big short little, improves tobacco seedlings regularity and seedling quality, meanwhile, controls transplanting time and improves production efficiency.But in nursery production practices, it is usually present leaf-cutting attention degree is inadequate and the irrational phenomenon of leaf-cutting degree.Leaf-cutting is improper can affect seedling cane length, increase the probability infecting stem black rot and delay tobacco seedlings grown in field speed, as leaf-cutting too gently or not leaf-cutting tobacco seedlings plant can be made too high, form high foot Seedling, root system is relatively small, not easily transplant survival.Leaf-cutting is overweight also can make that tobacco seedling growth speed is slow, seedling quality is weak.There are some researches show, leaf-cutting operation is the technical operation that Nicotiana tabacum L. seedbed phase virosis and bacterial disease propagate that risk is the highest.In the seedbed phase once there is disease in Nicotiana tabacum L., spread speed is very fast, it is easy to cause Nicotiana tabacum L. seedling of low quality, and lazy weight directly results in planting number and the reduction of yield of tobacco quality.
At present, tobacco floating seed rearing is based on workshop nursery, and leaf-cutting, as requisite technical operation in the floating seedlings process of workshop, is completed by leaf shearing machine.When tobacco seedlings carries out leaf-cutting in standard nursery pond, the leaf-cutting residue storage bag that leaf shearing machine carries at random needs to topple in time, and in the process toppling over residue, leaf shearing machine decommissions, originally the juice of machine run absorption drips under gravity, the juice of drippage causes the tobacco seedlings of wound directly to contact with leaf-cutting, promote the direct propagation of tobacco seedlings virus disease, serious harm tobacco seedlings seedling quality, even cause the generally generation of land for growing field crops tobacco virus, tobacco production and value and economic well-being of workers and staff are produced significant impact.

The effect that the present invention is arranged between sterilization pool, cleaning pond, sterilization buffering shows: one is on passageway, must play the effect entering personnel's Compulsory sterilizing in entering nursery place and booth；Two is arrange twice disinfection apparatus, it is possible to plays and strengthens the consciousness entering personnel decontamination diseases prevention；Three is to entering the hands of personnel and foot plays disinfective action.
In tobacco seedling is put into practice, the determination of sowing time is mostly based on transplanting time and carries out the calculating sowing time of retrodicting, normal conditions, the sowing time of pelleted seed can be retrodicted 60～65 days with transplanting time and be determined, can retrodict 50～55 days and be determined in little transplantation of seedlings area.To guarantee that tobacco seedlings is in time for transplantation of seedlings.According to the rule of effective temperature summation, (namely biology completes the growth promoter in a certain stage and must absorb certain heat from environment, total amount of heat required for each stage of development is a constant) and tobacco seed sprouting minimum temperature (7.5-10 DEG C) requirement, the determination of tobacco seedling concrete sowing time, will meet the temperature conditions that tobacco seed is sprouted.And how routine is retrodicted the seeding and growing seedling phase by experience or foundation transplanting time in producing, when have ignored sowing, in canopy, whether actual temperature meets the objective condition of cigarette kind germination and growth.The inventive method is while the seeding and growing seedling phase of retrodicting in conjunction with transplanting time, thermometer is adopted to measure seedling growth greenhouse inherent 8 points, 14 points, 20 points, the temperature of 24 periods, in seedling growth greenhouse, temperature measuring can according to 5 algoscopys, calculate meansigma methods and obtain mean daily temperature, METHOD FOR CONTINUOUS DETERMINATION, until when within continuous 7 days, mean daily temperature is higher than 10 DEG C, being just defined as the concrete sowing time.
In the present invention, after planting do not carry out substrate covering, it is prevented that cover substrate uneven, affect the concordance of tobacco seedlings germination and growth, stop hands in conventional production and spread substrate and cause covering uneven operation.
In the present invention, nursery pond put in time by tobacco seedlings drift dish after planting, interval time must not exceed 2h, prevent the seedling medium in drift dish air-dry in its natural state, affect seedling medium water suction and tobacco seedlings is sprouted, stop that conventional production carries out unifying drift after whole sabots again to put and cause seedling medium air-dry seriously, be unfavorable for the operation that substrate absorbs water in time.
In the present invention, owing to cigarette kind germination process does not need Fertilizer nutrient supply, therefore, after planting during Seedling neat to tobacco seedlings, do not carry out Term Fertilization, chlorella growth around here can be prevented, reduce the impact on the sprouting of cigarette kind and subsequent growth, stop many in conventional production is apply fertilizer after planting at once, provides the material energy for chlorella growth before seed germination.
The present invention is by adopting seeding technique accurately, and regularity and germination percentage that cigarette kind is sprouted all improve a lot, it is ensured that tobacco seedlings once survives quantity, fundamentally reduces workload of filling the gaps with seedlings between thinning link, reduces seedbed phase farming number of operations, reduces disease spread risk；Avoid because adopting many sowings in conventional production, and cause that single cave Seeding Quantity is more than 2, increase thinning workload, also result in the waste of cigarette kind.In production practices of the present invention, according to the height that seeding quality is actual, it is possible to carry out in single-deck limit row sowing two, to ensure to fill the gaps with seedlings source.But, by the tobacco seedlings filled the gaps with seedlings, because of operation subject to damage, affect tobacco seedling growth, cause tobacco seedlings growing way of filling the gaps with seedlings relatively weak and growth is slow, serious reduction seedling quality.
The method for expressing of leaf age actually occurs number according to true leaf, occurs simultaneously for young leaves, but the true leaf of curtailment 0.5cm is defined as 0.5, more than 0.5cm, be defined as 1 true leaf.
Pattern is planted in conjunction with current little hole depth, the high-quality seedling of pattern is planted for cultivating suitable little hole depth, when tobacco seedlings is in 4.4.5-5.5 leaf age, tobacco seedlings makes full use of drift disk space, carry out leaf-cutting operation, can substantially can not accomplish Seedling, it is ensured that the concordance of tobacco seedling growth, give full play to the effect of the short tobacco seedlings neat and consistent of leaf-cutting, also lay the first stone for later stage tobacco seedling growth neat and consistent and reduction leaf-cutting number of times.
4.5-5.5 leaf age Leaf cutting compares 4.5 leaf age Leaf cutting tobacco seedlings, when seedling, stem stalk height, thick two item data of stem are all of a relatively high, leaves number is basically identical, and in transplanting latter 10 days, leaves number is higher than 4.5 leaf age Leaf cuttings, and is above 4.5 leaf age Leaf cuttings at group's phase, the plant height of the phase of calming down cigarette strain, leaves number, maximum leaf length and width.
In tobacco seedling process, can control nursery link leaf-cutting number of times in 4.5 leaf age leaf-cuttings in period is 1-2 time, control the tobacco seedlings that leaf-cutting number of times is 1 time to carry out transplanting (as Chongqing Yan Qu transplants on April-30 on the 26th in relatively early stage, April 26 days the earliest, and when transplanting at the beginning of 5 months, need to carry out the 2nd leaf-cutting and could control its growth), and carry out leaf-cutting period at 4.5-5.5 leaf age, it is possible to achieve whole nursery Absent measures leaf-cutting number of times is 1 time.
The application of dreg-containing disk technology:
(1) before use, use disinfectant that dreg-containing disk is carried out spray disinfectant；
(2) in leaf-cutting process, when toppling over residue, before leaf shearing machine decommissions, dreg-containing disk is put under leaf shearing machine, above tobacco seedlings, it is ensured that leaf shearing machine end opening and residue reservoir bag are all within dreg-containing disk surrounding.
(3) turn off leaf shearing machine, after leaf-cutting residue is cleared up, and with disinfectant, leaf shearing machine is simply cleaned.
(4) open leaf shearing machine, allow leaf shearing machine dally about 1 minute, make residue residue and disinfectant under the effect of leaf shearing machine operating absorption, enter pouch.
(5) after leaf shearing machine works well, dreg-containing disk level being taken out, and brought out outside nursery pond below leaf shearing machine, this process is it is noted that steadily prevent the juice on dreg-containing disk from flowing out.
(6) leaf shearing machine starts leaf-cutting.The dreg-containing disk taking out nursery pond first rinses out residual juice with clear water, and is carried out by disinfectant, uses in order to next time.
The Main Function of dreg-containing disk:
In leaf-cutting operating process, when toppling over residue, leaf shearing machine shuts down, originally the juice of machine run absorption drips under gravity, by using the tobacco seedlings wound that the juice that dreg-containing disk technology can well stop drippage causes with leaf-cutting directly to contact, thus avoiding its disease spread brought.Meanwhile, before dreg-containing disk uses, by its disinfection, the effect to tobacco seedlings wound disinfection can be played with tobacco seedlings when dreg-containing disk directly contacts.By using dreg-containing disk technology, simple to operate, it is prevented effectively from residue low, blocks disease spread approach, reduce the seedbed phase general occurrence probability of virosis.
In the present invention, when extraneous mean daily temperature reaches 13 DEG C, just open the side form of described tobacco seedling culture canopy early be aerated printing opacity, both can better control tobacco seedlings growth rate, tobacco seedlings adaptive capacity to external world can be improved again, it is ensured that the tobacco seedlings after transplanting just has higher survival rate；Because in nursery early stage, general day temperature can reach 13 DEG C, even higher 30 DEG C, but nocturnal temperature is relatively low, therefore routine operation is all that requirement to be strictly incubated night, prevent freeze injury, cause when nocturnal temperature meets growth, still without carrying out taking off film, make the environment temperature and humidity that to be in canopy of a relatively high for tobacco seedlings, under such state, tobacco seedlings looks younger tender, adapts to land for growing field crops environment after being unfavorable for transplanting.
Detailed description of the invention
Hereinafter principles of the invention and feature being described, example is served only for explaining the present invention, is not intended to limit the scope of the present invention.
