Embodiment 1

[0016] The composition and content of preparation are as follows in the present embodiment, contain in every 100 milliliters of preparations:

[0017]

[0018] The preparation is prepared according to the above ratio. Firstly, the melatonin and the gibberellin are dissolved in ethanol and mixed evenly, then the remaining water is added to 100 ml, and the mixture is evenly mixed.

[0019] Take 100 ml of the preparation, add 10 liters of water, mix well, and spray evenly on the surface of tea tree leaves and branches 15 days before tea picking. Spray in the evening on a sunny day, spray once every 5 days, and spray 3 times . Tests show that after the application of this preparation, the content of free amino acids in tea tree leaves increases by 18.7%, while the content of tea polyphenols decreases by 11.1%, the ratio of phenol to ammonia decreases significantly, the bitterness of finished tea decreases, and the quality of summer and autumn tea is improved.

Embodiment 2

[0021] The composition and content of preparation are as follows in the present embodiment, contain in every 100 milliliters of preparations:

[0022]

[0023] The preparation is prepared according to the above ratio. Firstly, the melatonin and the gibberellin are dissolved in ethanol and mixed evenly, then the remaining water is added to 100 ml, and the mixture is evenly mixed.

[0024] Take 100 ml of the preparation, add 10 liters of water, mix evenly, and spray evenly on the surface of tea tree leaves and branches 20 days before tea picking, spray in the evening on a sunny day, spray once every 5 days, and spray 4 times . Tests have shown that after the application of this preparation, the content of free amino acids in tea tree leaves increased by 24.1%, while the content of tea polyphenols decreased by 13.4%, the ratio of phenol to ammonia decreased significantly, and the bitterness and astringency of the finished tea decreased, improving the quality of summer and autu...

Embodiment 3

[0026] The composition and content of preparation are as follows in the present embodiment, contain in every 100 milliliters of preparations:

[0027]

[0028] The preparation is prepared according to the above ratio. Firstly, the melatonin and the gibberellin are dissolved in ethanol and mixed evenly, then the remaining water is added to 100 ml, and the mixture is evenly mixed.

[0029] Take 100 ml of the preparation, add 10 liters of water, mix well, and spray evenly on the surface of tea tree leaves and branches 15 days before tea picking. Spray in the evening on a sunny day, spray once every 5 days, and spray 3 times . Tests show that after the application of this preparation, the content of free amino acids in tea tree leaves increases by 16.7%, while the content of tea polyphenols decreases by 12.2%, the ratio of phenol to ammonia decreases significantly, the bitterness of finished tea decreases, and the quality of summer and autumn tea is improved.

Abstract

The invention discloses a functional preparation for reducing the bitterness and astringency of summer and autumn tea and its application. The invention proposes for the first time that melatonin and gibberellin at appropriate concentrations are made into a functional preparation, which is healthy and environmentally friendly, easy to use, low in cost and non-toxic side effect. After the preparation is used, it can effectively regulate the content of polyphenols and amino acids in tea tree leaves, optimize the ratio of phenol to ammonia, reduce the bitterness and astringency of summer and autumn tea, and then significantly improve the quality of summer and autumn tea. The effect is obvious, and it can be widely used in tea garden production.

Description

technical field [0001] The invention belongs to the field of agricultural technology, and in particular relates to a functional preparation for reducing the bitterness and astringency of summer and autumn tea and its application. Background technique [0002] The tea produced in summer and autumn has a bitter taste, poor freshness and poor quality, so the economic benefits of summer and autumn tea are not high. With the continuous improvement of picking costs, about 50% of the fresh leaf raw materials in the total amount of tea produced in summer and autumn will be abandoned, resulting in a waste of a lot of tea resources and seriously restricting the sustainable development of the tea industry. Therefore, it is of great significance for the sustainable development of the tea industry to develop products and control technologies that improve the taste of summer and autumn tea, reduce the bitterness and astringency of fresh leaves of summer and autumn tea, and improve the qua...
