Abstract
The invention relates to a method for quick nondestructive detection on maturity of organic flue-cured tobacco leaves. The method is characterized in that 10-20 tobaccos are randomly selected from tobacco fields with consistent transplanting time and cultivation management measures, the color values (L*a*b* or/and L*C*h*) of 1-3 tobacco leaves in the middle (from bottom to top) are measured by a portable color difference meter, and the maturity of the organic flue-cured tobacco leaves is determined according to the color values. The method solves the difficult problem that specific indexes and specific determination methods are not given all the time during the harvesting process of the mature organic flue-cured tobacco leaves; the method is clear in index, has the objective judgment index, can quantify the maturity index and reduce visual errors, and is easy to operate and grasp; the method is used for judging the maturity of the organic flue-cured tobacco leaves, and can ensure that the harvested and flue-cured tobacco leaves are uniform in color, improved in quality, good in chromaticity and sufficient in aroma; and the method is suitable for tobacco planting and processing industries.
Description
Technical field
The present invention relates to by the method for utilizing the change color detection material, particularly the detection method of organic cured tobacco leaf maturity.
Background technology
Early 1990s at first proposes the concept of organic tobacco leaf abroad.At present, organic leaf tobacco production mainly is distributed in states such as U.S., Canada, Brazil, moral.2008, Yunnan, Guizhou began to attempt the organic tobacco leaf of plantation; 2009, the organic tobacco leaf planting of Yunnan-Guizhou part zone obtained organic authentication; Yunnan issue " organic tobacco leaf " provincial standard in 2010.At present, domestic and international organic cigarette production is being grown seedlings and facility (CN 101779593 A, a kind of method for culturing seedlings of organic cigarette seedling, China; CN 202197608 U, organic tobacco leaf floating seedlings dish, China), field cultivation management (CN 102812832 A, a kind of cultural method of organic flue-cured tobacco, China; CN 102093095 A, a kind of organic tobacco leaf bio-organic fertilizer special and preparation method thereof, China; CN 102630478 A, a kind of organic tobacco field planting and field management method, China; US74750809A, ANTAGONISTIC BACTERIA FOR PREVENTING AND ELIMINATING THE BACTERIAL WILT OF CONTINUOUS CROPPING TOBACCO AND THEIR MICROBIAL ORGANIC FERTILIZER, the U.S.), baking (CN 102640977 A, a kind of baking method that can effectively keep organic quality of tobacco, China; CN 102823933 A, a kind of baking of flue-cured tobacco method of organic tobacco leaf, China) etc. the aspect corresponding operating standard is all arranged.
Degree of ripeness is the central factor of quality of tobacco, and the field harvest maturity is the basis of cured tobacco leaf degree of ripeness, be baking process and the measure of cigarette processing technology can't remedy.But domestic and international organic tobacco leaf maturation is gathered and still is based upon on the conventional flue-cured tobacco harvesting standard at present, does not have clear and definite quantizating index and detection method.The patent that relates to the detection of tobacco leaf maturity in the Chinese patent database only has CN202110131U number " tobacco leaf degree of ripeness pick-up unit " and CN102323221A number " tobacco leaf degree of ripeness detection method and pick-up unit " two, disclosed detection method and device, it is the image that collecting unit obtains tobacco leaf to be detected, and this image handled to set up or be converted to the image of hsv color pattern, and obtain H, the S color component value of image; Go out the degree of ripeness grade MD of tobacco leaf to be detected according to given calculated with mathematical model.Be not difficult to find out that this method need be drawn great amount of images, workload is big, and still has the collimation error.Leaf color is one of important indicator of judging the tobacco leaf mature characteristic, but is subject to the influence of people's subjective factor.Therefore, only rely on people's visual determination tobacco leaf degree of ripeness, exist instability problem to a certain extent.
Summary of the invention
The object of the present invention is to provide a kind of fast non-destructive detection method of organic cured tobacco leaf degree of ripeness, adopt portable colour difference meter, detect land for growing field crops organic flue-cured tobacco ripening period tobacco leaf color value and change, according to the variation range of differing maturity tobacco leaf color value, quantize the tobacco leaf picking degree of ripeness.
To achieve these goals, the method that the inventor provides is before organic tobacco leaf normal mature is gathered, from the transplanting phase vega consistent with the cultivation management measure, select 10～20 strain cigarettes at random, use portable colour difference meter, measure the L*a*b* of 1～3 tobacco leaf of middle leaf from the bottom up or/and the L*C*h* color value is determined the tobacco leaf degree of ripeness according to color value; Specific practice is:
Use the L*a*b* color value to judge organic tobacco leaf degree of ripeness: at first, by correction plate correcting chromatic aberration meter, indexs of correlation such as colour measurement L*a*b* to be set, to measure tobacco leaf then; When 1～3 organic tobacco leaf color value L* that measures between 62～74, a* value is between-7～0, b* value then is defined as detection tobacco leaf maturation between 50～62 the time, can a picking and roasting;
Use the L*C*h* color value to judge organic tobacco leaf degree of ripeness: at first, to rectify an instrument by correction plate, indexs of correlation such as colour measurement L*C*h* are set, measure tobacco leaf then; When 1～3 organic tobacco leaf color value L* that measures between 62～74, C* value is between 50～62, h* value then is defined as detection tobacco leaf maturation between 85～100 the time, can a picking and roasting;
In the described L*a*b* color value, L* is brightness value: in vain, represent brightness, 0～100 from black; A* is red scale value: from green to red, and-A～+ A; B* is yellow value degree: from indigo plant to the Huang, and-B～+ B; In the described L*C*h* color value, L* is brightness value: in vain, represent brightness, 0～100 from black; C* represents chroma; H* represents hue angle.
The model of above-mentioned portable colour difference meter is CR-410.
In the said determination operation, every leaf should select to detect 6 points, and namely leaf tip, middle part and the leaf base of master pulse both sides blade central authorities are avoided blade master offshoot as far as possible, get its mean value then.
The inventor points out: above-mentioned L*a*b* and L*C*h* color value can be judged organic tobacco leaf degree of ripeness simultaneously, also can singlely detect judgement; The color value of above-mentioned ripe tobacco leaf is the empirical value through several expert's long-term practice.
Method of the present invention has solved in the ripe recovery process of organic flue-cured tobacco and has never had clear and definite index and the difficult problem of assay method.This method index is clear and definite, has objective judge index, can quantize the degree of ripeness index, can reduce the error that vision causes, and operates easily and grasp.Adopt this method to judge organic tobacco leaf degree of ripeness, tobacco leaf color uniformity behind the picking and roasting, quality improves, and colourity is good, the fragrance foot.Be applicable to tobacco planting and processing industry.
