Abstract
The invention discloses a method and an accelerator for improving the aroma of summer tea and a preparation method thereof. In the method, endogenous signal substances of stressed tea trees are applied in the preparation of the accelerator for improving the aroma of summer tea. The preparation method comprises the following steps of: preparing exogenous ABA and SA into high-concentration mother solution by using 50 percent ethanol, and preparing the mother solution into a spraying agent by adding water during spraying; and performing the spraying on the tea trees before tea leaves in summer are picked, picking the tea leaves a week later and processing the picked tea leaves into tea. The method can improve the content of aromatic substances in the tea leaves, and has the obvious effect of improving the content of the aromatic substances of the conventional fresh tea leave materials and the value of finished tea leaves. The method has the characteristics of simplicity, low production cost, no chemical pollution and natural quality of the tea leaves.
Description
Technical field
The invention belongs to the Tea Production technical field, especially improve the high-quality Tea Production technology of tea aroma, be specifically related to a kind of the improve method of aroma of summer tea, promoter of raising aroma of summer tea and preparation method thereof.
Background technology
Under summer high light, high temperature, super-humid conditions, growth of tea plant is vigorous, and material pained highly seasoned in the bright leaf inclusion of tea is more; Content of cellulose is high; Aromatic substance and pure and mild flavor material are less, and tea leaf quality descends, and Oolong tea, the green tea quality of processing are relatively poor; Production unit is adopted less and is not even adopted summer tea, has had a strong impact on the economic benefit in tea place.
At present to improving the summer tea Study on Quality; Be from the Crop Physiology aspect on the one hand; Mainly be the normal growth growth that the research favourable circumstance helps tea tree, be beneficial to the formation of tealeaves effective ingredient such as materials such as amino acid, Polyphenols, particularly the flavour composition is more favourable to tea leaf quality; Normally help the normal growth growth of tea tree, be beneficial to the formation of tealeaves effective ingredient such as materials such as amino acid, Polyphenols through the improvement environment; Be that prior art can be improved the summer tea flavour to a certain extent from research improves the summer tea quality from the processing technology aspect to the summer tea raw material on the other hand, tea leaf quality increases, but the low light never improvement of aroma of summer tea.
Summary of the invention
The objective of the invention is to overcome the deficiency of prior art, a kind of method that improves aroma of summer tea is provided, easy to implement, simple efficient, through improving aromatic substance content in the summer tea, thereby obviously improve the fragrance of summer tea.
Another object of the present invention provides a kind of promoter of improving aroma of summer tea.
Also purpose of the present invention provides the preparation method of above-mentioned promoter.
The present invention realizes above-mentioned purpose through following technical scheme:
The invention provides a kind of method that improves aroma of summer tea; Be summer the tea place use abscisic acid (ABA) through external source and salicylic acid (SA) mixed liquor etc. is coerced semiochemicals; Make tea tree performance and low temperature and coerce phenomenon autumn in spring, induce the formation and the accumulation of tea tree aromatic substance, improve the relevant degrading enzymatic activity of aromatic substance precursor substance simultaneously; Thereby quicken the degraded of aromatic substance precursor; Form more abundant free state aromatic substance, improve the kind and the concentration of aromatic substance in the tealeaves, finally improve tea aroma.
The present invention provides a kind of promoter of improving aroma of summer tea simultaneously, comprises abscisic acid (ABA) ethanolic solution, salicylic acid (SA) ethanolic solution and water.
The total concentration of contained said abscisic acid (ABA) and salicylic acid (SA) is preferably 50ppm～100ppm in the promoter of the present invention.
The preparation method of promoter according to the invention may further comprise the steps:
(1) calculate by weight, Exogenous ABA is made into the mother liquor of 1000ppm～2000ppm high concentration with 50% (volume by volume concentration, down together) ethanol;
Calculate by weight, external source SA is made into the mother liquor of 1000ppm～2000ppm high concentration with 50% ethanol;
(2) get ABA and SA mother liquor, be configured to mix mother liquor by 3: 2 volume ratios;
(3) get the mixing mother liquor and convert 20 times of promoter that obtain 50ppm～100ppm concentration of water dilution.
The invention provides the application of said promoter, be applied to tea tree is sprayed, improve aroma of summer tea.
Specifically can, summer tea spray promoter processing before plucking to tea tree.The best period that sprays is annual (hot stage) time in 5～September, when growth of tea plant goes out young sprout, sprays when tea tree young sprout length is to 1 bud 2 or 3 leaves in summer.
Preferred scheme is: plucked preceding 6～8 days at summer tea, during the exhibition just of tender shoot elongation to 1 bud 2,3 leaves of tea tree, select after at 4 o'clock in the afternoon at fine or cloudy day; Every mu of tea place sprays the promoter 50kg of 50ppm～100ppm concentration; After 3 days again spray once spray in back 24 hours as rainy, fill spray once; The back harvesting of one week is processed into tealeaves by the common tea processing method.According to environment environmental condition and growth of tea plant situation, carry out as stated above and can multiple batches of use improve summer tea gas.
Compared with prior art, the present invention has following beneficial effect:
Innovative point of the present invention is the fragrant high strong principle of particular surroundings formation tea in spring and autumn according to winter in spring and autumn low temperature and drought stress; Utilize plant under stress conditions; Can synthesize abscisic acid (ABA) and salicylic acid (SA) etc. rapidly and coerce semiochemicals and semiochemicals quantity and with the degree of coercing substantial connection is arranged, therefore, coercing semiochemicals to external source adds on the tea tree; Directly perhaps cause that indirectly corresponding stress physiology phenomenon appears in tea tree; Show and coerce identical physiological change naturally, thereby change tea tree internal metabolism level, finally influence the kind and the content of secondary substance in the tea tree body.Summer the tea place use abscisic acid (ABA) and salicylic acid (SA) etc. through external source and coerce semiochemicals; Make tea tree performance and low temperature and coerce phenomenon autumn in spring, induce the formation and the accumulation of tea tree aromatic substance, improve the relevant degrading enzymatic activity of aromatic substance precursor substance simultaneously; Thereby quicken the degraded of aromatic substance precursor; Form more abundant free state aromatic substance, improve the kind and the concentration of aromatic substance in the tealeaves, finally improve tea aroma.
The present invention improves tea aroma promoter and application thereof, is applicable to that the fresh leaves of tea plant of planting any kind Anywhere is a raw material, like black tea, green tea, Oolong tea etc., has wide range of applications.
The present invention has obvious effect for aromatic substance content that improves existing fresh tea leaf raw material and finished tea value, and method is simple, and production cost is low; ABA and SA are the endogenous substances of tea tree; Under the environment-stress condition, in the tea tree body synthetic and accumulate more, therefore; There is not chemical contamination in tealeaves after tealeaves after this processing is handled, has the natural quality characteristics of tealeaves.
