In detail, first vega can be sorted out, and can also be classified in units of different farmers, then
Field investigation is carried out to all kinds of vegas.
The classification of vega must carry out after topping after more than 80% vega cigarette strain dome；Vega is divided at least one
A vega classification, the criteria for classification of vega can be classified according to the growing state of vega, can be divided into " greatly strong cigarette ", " in
In strong cigarette ", " cigarette on the weak side " and " excessively prosperous cigarette " at least two or be divided into " good ", " in ", at least two classes in " poor ".It needs
Illustrate, if after vega is divided into Ganlei, can by the area of all kinds of vegas, unit area cigarette strain plantation amount and point
Situations such as cloth, is inserted in the registration form made in advance, such as table 1.
1 ×× year of the table ×× baking all kinds of vega area ratio registration forms (pattern) in section
It should be noted that the criteria for classifying of above-mentioned " cigarette strong greatly " can be：Cigarette strain 115 ± 5cm of plant height, stem girth 9.5 ±
0.5cm, 20 ± 1, the effective leaf of single plant；The top long 60-70cm of 3 leaf, wide 20-24cm；3 leaf of waist leaf long 75-85cm, wide 26-
30cm；The lower two canopy long 65-75cm of 4-5 leaves, wide 28-32cm；Dolioform-near tubular of plant type, dark green leaf color normally fall Huang." in
The criteria for classifying of strong cigarette " can be：Cigarette strain 105 ± 5cm of plant height, 9.0 ± 1.0cm of stem girth, single plant leaves number 18 ± 1；Top
The portion long 50-60cm of 3 leaf, wide 16-20cm；3 leaf of waist leaf long 65-75cm, wide 22-26cm；The lower two canopy long 55-65cm of 4-5 leaves, it is wide
24-28cm；Dolioform-near tubular of plant type, dark green leaf color normally fall Huang.The criteria for classifying of " partially prosperous cigarette " can be：Cigarette strain stem is thick
" cigarette strong greatly " is typically larger than with tobacco leaf length, and leaf color is dark green, falls yellow slow.The criteria for classifying of " cigarette on the weak side " can be：Cigarette strain
Highly, stem is thick and tobacco leaf length is significantly less than " in strengthen cigarette ", and leaf color is light green, falls yellow too fast.It should be further noted that this
Described effective leaf refers to can be used in the Mature Tobacco Leaves for making flue-cured tobacco in invention.Above-mentioned effective leaf refers to that every plant of cigarette strain can
It picks to prepare the leaf of flue-cured tobacco.
Above-mentioned dome refers to that cigarette strain is grown for (10-15 days) after topping by certain time, and upper leaf is fully deployed, in
Portion's leaf size approaches, and cigarette strain appearance is in the state to finalize the design almost.
In at least one representative monitoring field of the field division of each classification, 1-2 representative prison can be usually divided
Field is surveyed, and the slotting board marked or slotting rod mark are inserted into each representative monitoring field.It is it should be noted that different
The mark of the representative monitoring field of vega classification or record, can be identified according to specific geographic position with reference to vega classification
And differentiation.
Divided in selected all kinds of representative monitoring fields it is at least one represent sampling point, usually each representative monitoring field
The quantity for representing sampling point of block is 1-2.It should be noted that the selection for representing sampling point preferably may be located remotely from field side, go deep into
Field is chosen.In detail, the 8-12 plants of cigarette strains for investigation can be included as investigation cigarette strain in each sampling point that represents, and
This 8-12 plants of investigation cigarette strain can continuously be grown on the cigarette strain in field, i.e., above-mentioned 8-12 plants of investigation cigarette strain can be planted in
The cigarette strain of same plantation row；It should be noted that the selection of investigation cigarette strain can be carried out according to the trait expression of vega entirety
Selection, enables investigation cigarette strain to represent the whole growing state of tobacco leaf in sampling point.Further, in investigation cigarette strain selection
Afterwards, you can investigation cigarette strain is marked, such as：Can first plant as investigation cigarette strain cigarette strain top indicator, and
In top indicator of last plant as the cigarette strain of investigation cigarette strain, and then can facilitate to representing all investigation cigarette strains in sampling point
It is tracked investigation.Above-mentioned mark is for example：Can on the top bolt of cigarette strain brightly painted rope etc..
From first round tobacco leaf also prematurity when, proceed by the field investigation of Maturity of Tobacco Leaf.In detail, the maturation of tobacco leaf
It is ripe from below to up, and then in the ripe number of sheets of every plant of cigarette strain of counting, can starts counting up, and press from the lower part of cigarette strain
It is counted according to the ripeness standard of leaf position residing for tobacco leaf and (blade quantity and weight etc. can be included), and can be by each field class
The field investigation of other all kinds of Maturity of Tobacco Leaf is recorded in record sheet, such as table 2.
Table 2XX toasts all kinds of tobacco leaf maturation situation field investigation record sheets in section
Note：1. A is ×× class tobacco leaf at ××, B is ×× class tobacco leaf at ××, and C is that ×× class tobacco leaf, D are at ××
×× class tobacco leaf at ××.(such as：A is " cigarette strong greatly "；B is " in strengthen cigarette "；C is " partially prosperous cigarette "；D is " cigarette on the weak side ")
The average picking leaves number of the current each point of " 2. adopting feelings remarks " essential record or the remaining number of sheets.
3. related number of sheets record, only remains into one decimal place.
It should be noted that when carrying out every plant of climax leaves counting number for investigating cigarette strain, the number of climax leaves can be only counted
Amount can also count the quantity of climax leaves and count the total weight of climax leaves simultaneously；If the number of blade of climax leaves is counted simultaneously
Amount and total weight, then needed before field investigation is carried out, that is, need before current tobacco leaf closes on maturation, in the generation of representative field
Table sampling point nearby carries out, and using the cigarette strain near representative sampling point as simulated object, the Mature Tobacco Leaves of simulated object are taken,
It weighs；If only calculate climax leaves blade quantity, then can according to plantation each mature leaf of empirical estimating weight,
Further according to the weight per leaf of the mature leaf of estimation, calculate the total weight of climax leaves, can also be it is random win Partial mature leaf into
Row is weighed, and estimates the gross weight of all climax leaves.It should be further noted that the different baking round Mature Tobacco Leaves of flue-cured tobacco cigarette strain
The calculating of weight per leaf will especially carry out before the first a heatable brick bed baking of each wheel hypo-tobacco leaf, choose 100 tobacco leaves, calculate average weight
Amount.
It should be further noted that according to the climax leaves quantity of all investigation cigarette strains counted in the manner described above, total
Weight and average climax leaves amount and the specific strain number for investigating cigarette strain also represent quantity, the number of representative monitoring field of sampling point
Amount and the cigarette strain plantation amount of the quantity of field (all kinds of vegas) considered, area and unit area is needed to calculate every class cigarette respectively
Effective tobacco leaf in field and/or the total quantity and total weight of Mature Tobacco Leaves match somebody with somebody a heatable brick bed so as to carry out homogeneity in time to similar vega,
And the ripe harvesting of timely and appropriate discovery.
In detail, can be multiplied by with the ripe number of sheets for the average each investigation cigarette strain for representing sampling point the generation represented where sampling point
Table monitors total cigarette strain quantity of field, obtains the representative monitoring field climax leaves amount of band, then ripe with representativeness monitoring field
The vega of classification where leaf amount is multiplied by representative monitoring field and the area ratio of representativeness monitoring field, you can obtain each cigarette
The suitable of field classification adopts tobacco leaf amount；It can also be where directly calculating the investigation cigarette strain with the ripe number of sheets of average each investigation cigarette strain
Total ripe number of sheets of the vega of classification, i.e., classification cigarette where being multiplied by the investigation cigarette strain with the ripe number of sheets of average every plant of investigation cigarette strain
Total cigarette strain quantity in field；Further, can also be intended to be multiplied by tune with the ripe number of sheets for representing the average each investigation cigarette strain of sampling point
The mu cigarette strain plantation amount of the vega of classification where cigarette strain is looked into, obtains the climax leaves per mu yield of category vega, then with climax leaves mu
The gross area of classification vega where yield is multiplied by investigation cigarette strain.
Further, it is since the lower part of cigarette strain to hold above-mentioned and tobacco leaf ripe and picking, counts every plant of cigarette strain
The methods of climax leaves can include：The blade of each cigarette strain is divided into inferior leads, middle leaf and upper leaf, and to inferior leads,
Middle leaf and upper leaf count lower part climax leaves, middle part climax leaves and top climax leaves respectively.
It should be further noted that judge whether tobacco leaf is ripe, first, grasping leaf color and vein color comprehensively
Variation degree；Second is that seeing whether tobacco leaf base portion has shown mature characteristic clearly, judge whether inferior leads, middle leaf and upper leaf are ripe
It can be distinguished according to following characteristics：
The feature of lower part climax leaves includes：The green middle yellowing in green and blade face is moved back to yellow green in blade face, and master pulse has the length of 1/2-2/3
Degree bleaches, and offshoot substantially bleaches mostly, such as the offshoot that can have no less than 50% bleaches, and the offshoot chlorisis positioned at base portion turns
Huang, when the offshoot of above-mentioned base portion can refer to that tobacco leaf is grown on mobile jib, close to the offshoot of mobile jib on blade.
The feature of middle part climax leaves includes：Blade face is in yellow green or green-yellow, and the length that master pulse has 3/4-4/5 bleaches, and is propped up
Arteries and veins bleaches shinny mostly, and yellow bright, auricle yellowing is presented in the offshoot of base portion；Cauline leaf angle is close to 90 °.
The feature of top climax leaves includes：Blade face turns yellow (yellow is presented in more than 90% blade face) corrugation with patch (spot
Block is more) (during upper leaf maturation blade face with patch quantity can be more than middle leaf maturation when middle part leaf surface with spot
Number of blocks), auricle turns yellow, and master pulse is substantially all to bleach (ratio can be in 95%-100%)；Offshoot bleaches mostly, and (ratio can be with
More than 85%), and the offshoot presentation of leaf base is yellowish-white shinny；Blade tip, which rises, to be hooked, and has withertip and focus side phenomenon.
It needs further to illustrate, when distinguishing by position and grasping tobacco leaf mature characteristic, it should be noted that cigarette strain
Nutrition condition and the influences such as the weather in maturity period.Wherein, the ripe fast resistance to maturity of tobacco leaf is poor, shows when being mature on the whole feature
It should just harvest；Ripe slower tobacco leaf is more resistance to ripe, and after the feature that is mature on the whole is shown, when weather is preferable can delay 2-3 days adopts
It receives, to further improve the ratio of tobacco leaf picking maturity and roasting rear first-class cigarette.
Tobacco leaf amount (fresh tobacco leaf weight) is adopted according to suitable for filling smoke requirement and fitting, determines that single list a heatable brick bed tobacco leaf is fitted the phase of adopting, and
Tobacco leaf, which fits the definite of the phase of adopting, to be carried out respectively for the vega classification marking off in advance, growing state is different.In detail, from
First round tobacco leaf moves back green, will enter the climax leaves quantity and again that baking start counting up each classification vega before not yet ripe again
Amount etc., until the total amount on the same day of climax leaves can complete the tobacco flue-curing of single list a heatable brick bed or can complete one in second day
The tobacco flue-curing of secondary single list a heatable brick bed is that tobacco leaf is fitted the phase of adopting at this time, i.e., the suitable of tobacco leaf adopts phase beginning.
It should be noted which day after being on the day of investigation in the weight (quantity) for judging climax leaves can reach single
During the suitable dress smoke of secondary list a heatable brick bed baking, Mature Tobacco Leaves total amount in each classification field that the same day is investigated and calculates can also be used
Divided by baking climax leaves standard of plucking, it obtains the suitable of the present invention and adopts tobacco leaf amount, further, baking climax leaves standard of plucking (P)
During to toast, the 80-90% of the total amount of whole tobacco leaves of picking should be accounted for per the quantity of a heatable brick bed Mature Tobacco Leaves, is calculated in aforementioned manners
If the suitable suitable dress smoke adopted tobacco leaf amount and disclosure satisfy that single list a heatable brick bed, be exactly that the suitable of tobacco leaf adopts the beginning second day of investigation
Phase；It needs further to carry out Maturity of Tobacco Leaf if the tobacco leaf amount calculated is not met by the suitable dress smoke of single list a heatable brick bed
Field investigation.
The total amount of above-mentioned climax leaves can refer to that each classification vega each toasts total suitable of all cigarette strains of round and adopts cigarette
Ye Liang, the suitable calculating for adopting tobacco leaf amount are carried out according to preceding method.
It should be noted that different roasting modes has different suitable dress smoke requirements, such as：
(1) comb cigarette folder baking：Often bake 310~350 folders.(fresh cigarette is often pressed from both sides suitable for fresh cigarette gross weight 3500kg~4500kg
11.0~13.5kg).
(2) fast cage type tobacco clamp toasts.Often bake the dress folder of cigarette 280 left and right.It is (every suitable for fresh cigarette gross weight 3600kg~4500kg
Press from both sides fresh 13.0~16.0kg of cigarette).
(3) pole baking is hung.Per 400~530 pole of a heatable brick bed pole number (per pole 130-150 pieces), suitable fresh cigarette gross weight 3000kg~
4000kg (per pole fresh cigarette weight, inferior leads per 7~8kg of pole, in, upper leaf is per 9~10kg of pole).
Therefore, when whole suitable of all cigarette strains of more each round adopts tobacco leaf amount and the suitable dress smoke of single list a heatable brick bed,
It should also be taken into account that the mode of tobacco flue-curing.
It should be further noted that described above suitable for filling in the range of smoke, the preferably appropriate more dresses of resistance to flue-cured tobacco are (more
Adopt), preferably suitably fill (adopting less) less intolerant to roasting leaf；The preferably appropriate more dresses (more adopting) of the small tobacco leaf of moisture, the big tobacco leaf of moisture are preferably appropriate
Few dress (adopting less).Therefore, the resistance to roasting property of tobacco leaf and water content are also that all the suitable of cigarette strains whole of more each round adopt tobacco leaf amount
With factor needed to be considered during the suitable dress smoke of single list a heatable brick bed.
Preferably, when compared with being fitted with Tanaka with tobacco leaf demand of the different parts tobacco leaf with a heatable brick bed and adopt tobacco leaf amount, to adopt
Top climax leaves, middle part climax leaves and the lower part climax leaves amount taken should also reach following ratio (P), baking climax leaves picking
Standard P：
When toasting lower tobacco leaf, the 80-85% of the tobacco leaf total amount under picking should be accounted for per the quantity of a heatable brick bed Mature Tobacco Leaves；Such as：
80%th, 81%, 82%, 83%, 84%, 85%.
During the tobacco leaf of baking middle part, the 85-90% of the tobacco leaf total amount under picking should be accounted for per the quantity of a heatable brick bed Mature Tobacco Leaves；Such as：
85%th, 86%, 87%, 88%, 89%, 90%.
When toasting upper tobacco leaf, 90% or so of the tobacco leaf total amount under picking should be accounted for per the quantity of a heatable brick bed Mature Tobacco Leaves；Example
Such as：88%th, 89%, 90%, 91%, 92%.
It needs further to illustrate, in the suitable of the i.e. each all cigarette strains wholes of baking round of total amount for calculating climax leaves
Can be that single tobacco leaf planting peasant household individually calculates when adopting tobacco leaf amount, it at this time can be according to same a heatable brick bed tobacco leaf homogeneity principle tissue
Tobacco leaf picking, with a heatable brick bed, to fill an a heatable brick bed " homogeneous (tobacco leaf inserted part is consistent, maturity is consistent) " tobacco leaf, 1-2 can be shifted to an earlier date
Its certain estimated class vega adds up that area, calculating formula must be adopted：It is expected that vega (mu)=barn must be adopted suitable for filling smoke (kg) ÷ classes
The Mature Tobacco Leaves total (kg/ mus) that vega can be picked per acre × adopt the total accountings of after ripening Ye (baking climax leaves standard of plucking, P),
The computational methods of certain above-mentioned class vega climax leaves sum per acre are carried out with reference to the suitable computational methods for adopting tobacco leaf amount；Can also be multiple
Tobacco leaf planting peasant household calculates jointly, you can be that the peasant household (rich and influential family) of single tobacco leaf planting individually carries out " homogeneity is with a heatable brick bed " baking
Or can be that multiple peasant households " homogeneity is with a heatable brick bed " are toasted.
It is used to determine that the Maturity of Flue-cured Tobacco field investigation of tobacco leaf suitable collection period to be determined to the present invention with reference to embodiments
Amount Forecasting Methodology is described in further detail.
