It follows that said method is being further described in more detail:
Step 102, the more than one Nicotiana tabacum L. randomly drawed from the Nicotiana tabacum L. of farmland planting, it is defined as Nicotiana tabacum L. to be won；
Owing to tobacco leaf planting time of same farmland planting, applying fertilizer, absorption nutrient are the most unified, randomly select
More embody the science of this monitoring method, accuracy.The amount of randomly drawing is preferably based on 30-60 sheet fresh tobacco leaf.
Step 104, measures the length of Nicotiana tabacum L. to be won, obtains length value；
The length of Nicotiana tabacum L. is as the growth of Nicotiana tabacum L. and incrementally increases, and uses the length of Nicotiana tabacum L. to weigh Nicotiana tabacum L. plucking time and is
More science.
Step 106, measures the blade face breakage ratio of Nicotiana tabacum L. to be won, and obtains damaged value；
The breakage rate of Nicotiana tabacum L. can be more and more obvious along with the growth of Nicotiana tabacum L., because Nicotiana tabacum L. in early days is big due to water content, and bullet
Property relatively strong, by certain impact can with damage, but, if Nicotiana tabacum L. grows to a certain degree, owing to blade face area is big, bullet
Property weaken, water content reduce, the most destroyed by impulsive force.Therefore, breakage value is used to weigh the plucking time of Nicotiana tabacum L. more
Science.
Step 108, scans Nicotiana tabacum L. to be won and obtains scanogram；Scanogram is compared with reference to image with Mature Tobacco Leaves,
Ripe color-ratio to Nicotiana tabacum L. to be won；
Using the most superb scanning technique (such as: take pictures), and image comparison techniques, very easy extraction waits to pluck
Take the ratio of ripe color in Nicotiana tabacum L..
Along with the growth of Nicotiana tabacum L., the blade face of Nicotiana tabacum L., vein color can have greatly changed, but grow to certain phase
The blade face of Nicotiana tabacum L., vein color possess uniformity, therefore, determine Nicotiana tabacum L. plucking time more section according to ripe color-ratio
Learn.
Color includes blade face color and/or vein color.Color, with the variation tendency of Maturity, see table 1.

| 100% | Leaf color Huang entirely, master pulse, one-level offshoot are the whitest |
| 90% | Ye Sejiben Huang entirely, master pulse are the whitest |
| 80% | Leaf color 8-9 becomes Huang, master pulse 2/3 to turn white |
| 70% | Leaf color 6-7 becomes yellow, master pulse is the whitest |
| 60% | Leaf yellow skin is green |
| 50% | Leaf color is light green |
| 40% | Dark green leaf color |
| 30% | The performance of improper color is more than 10% |
Step 110, transfers the growth time of Nicotiana tabacum L.；
Owing to the growth time of Nicotiana tabacum L. is monitored and records always, therefore, the growth time of Nicotiana tabacum L. is very easy to adjust
Take.And, Nicotiana tabacum L. is along with the prolongation of growth time, progressively ripe, so, harvesting Nicotiana tabacum L. is more section to use growth time to determine
Learn.
Step 112, detects the mesophyll sedimentation of Nicotiana tabacum L. to be won；
Owing to, in Nicotiana tabacum L. developmental process, the sedimentation of mesophyll can change, the same phase grows up, reaches identical Maturity
The mesophyll sedimentation of Nicotiana tabacum L. is constant, therefore, utilizes the mesophyll sedimentation of Nicotiana tabacum L. to carry out the determination of Nicotiana tabacum L. plucking time more
Science.
Step 114, detects the elasticity of Nicotiana tabacum L. to be won；
Ibid analyzing, owing to containing substantial amounts of moisture content in Nicotiana tabacum L., during Nicotiana tabacum L. is grown up, water content can occur bigger change
Change, but, the moisture content of the Nicotiana tabacum L. of identical Maturity is essentially identical, and the elasticity hence with Nicotiana tabacum L. determines Nicotiana tabacum L. plucking time more
Science.
Mesophyll sedimentation, the elastic variation tendency with Maturity, be shown in Table 2:
Table 2 mesophyll sedimentation, the elastic variation tendency with Maturity
| Maturity (%) | Mesophyll sedimentation, elasticity |
| 100% | Ripe speckle loose, full of elasticity, a large amount of |
| 90% | Loose, flexible, have ripe speckle |
| 80% | Speckle loose, the most elastic, slightly ripe |
| 70% | Slightly loose, slightly elastic |
| 60% | Slightly loose, the hardest |
| 50% | The closeest, slightly hard, |
| 40% | The closeest, the most crisp, |
| 30% | Breakage, scab etc. are more than 20% |
According to table 2, it is also possible to determined the plucking time of Nicotiana tabacum L. by ripe speckle.
Step 116, determines the thickness of Nicotiana tabacum L.；
Ibid analyzing, Nicotiana tabacum L. can progressively thicken along with growth, Nicotiana tabacum L., but, along with Nicotiana tabacum L. is ripe by maturation to transition, cigarette
The thickness of leaf is on a declining curve.But, the moisture content of the Nicotiana tabacum L. of identical Maturity is essentially identical, thickness is essentially identical, therefore, and profit
Nicotiana tabacum L. plucking time more science is determined with the thickness of Nicotiana tabacum L..
The thickness of Nicotiana tabacum L., with the variation tendency of Maturity, is shown in Table 3
The thickness of table 3 Nicotiana tabacum L. is with the variation tendency of Maturity
| Maturity (%) | The thickness on blade face |
| 100% | Medium, substantial, shrinkage |
| 90% | Medium |
| 80% | Medium the thinnest (thick) |
| 70% | The thinnest (thick) |
| 60% | Base portion the thinnest (thick) |
| 50% | Thin (thick) |
| 40% | Light (thorn firmly) |
| 30% | Nutritional deficiency or harm influence, mechanical injury etc. are more than 20% |
Step 118, according to length value, damaged value, ripe color-ratio, the growth time of Nicotiana tabacum L., mesophyll sedimentation, bullet
Property, Nicotiana tabacum L. thickness in more than three indexs be analyzed, draw monitored results.
This monitored results includes: wins Nicotiana tabacum L. or does not win Nicotiana tabacum L..
When Nicotiana tabacum L. maturation, above-mentioned each index can keep the concordance of height, therefore, in order to determine Nicotiana tabacum L. more accurately
Plucking time, need three or more indexs is fully compared, analyzed, draw monitored results.
