1. Seed harvesting: collect mature fruits from October to November every year.
2. Seed treatment:
(1) Rubbing, rinsing the peel, fishing for sunken full of seed particles, shade drying and then wind clean, it will be pure seed.
(2) break the dormancy of the bitter tea seeds. Bittering tea belongs to the physiological maturity, generally use wet sand layer method, in addition can also change the temperature treatment or to different concentrations of chemicals to break dormancy.
3. Nursery, transplanting, seedling management is the same as conventional.
4. Planting specifications: generally in November to February planting.
5. Planting specifications: to take is the degree of dense dwarfing technical measures, plant spacing 2 meters × 1.5 ~ 1.8 meters, pit specifications 1 m × 0.8 ~ 0.7 meters. Asexual reproduction generally have cuttings, compression and grafting three methods, after many experiments and practice has proved that the bitter tea, regardless of the type of propagation, the survival rate of more than 80%, is now on the local commonly used, the operation of the more convenient cuttings propagation for a brief introduction.
1. Tidy the bed and soil. The bed is 100cm wide, 30cm high, and the length is convenient for work. Soil composition and proportion according to vermiculite powder: river sand: fire soil = 3: 5: 2.
2. Spike preparation
(1) spike to young trees is good, select the current year lignification or half lignification of the good branches.
(2) scion pruning. The length of the spike, generally about 4 cm, each section of at least 2 to 3 axillary buds (latent buds), cut, the upper end of the spike to stay a leaf 1/2 or full leaf (spike to stay the number of leaves, should be determined depending on the size of the spike to facilitate photosynthesis is appropriate) the lower end of the incision close to the base of the axillary buds or the internode, and cross-cut into a vertical cross-section, it is a small cut, healing fast.
3. Plant hormone treatment. Bitter tea is difficult to root species, plant hormone treatment good or bad directly affects the growth of roots and survival rate, the use of ABT1 rooting powder, the effect is more ideal, first according to the maturity of the spike, the mother liquor diluted into the required concentration, generally: quick dip spike concentration of 500 ~ 1000 ~ 2000PPM, processing time of a few seconds to 30 seconds, slow dip spike concentration of 50 ~ 100 ~ 200PPM. Dip time is 0.5 hours ~ 1 hour ~ 2 hours.
4. Cuttings. Choose a rainy day or evening, to the extent that the leaf surface does not overlap, the spike straight into the substrate, the depth of the spike length of 2 / 3, short spike, should be deep rather than shallow.
5. Transplantation, cuttings 2 ~ 3 months later, axillary buds began to sprout 3 ~ 4 mm, proving that the spike has been rooted, continue to care for a period of cultivation, the new root grows to 1 ~ 2 cm, can be transplanted to the nutrient film bags, such as seedling height of 26 ~ 30 cm, you can get the planting of the tea garden. Withering mainly three methods:
(1) heating withering: with the help of electric heat, wood charcoal artificial heating, fast, efficient, but if the fire is not mastered, the quality is not easy to guarantee.
(2) indoor natural withering: mainly in the ventilated light room. That is, with bamboo cushions will be evenly spread tea, shall be about 15 ~ 20 hours, and evenly turned several times, so that water evaporation up to 50% ~ 60%, petiole, leaf buds soft that is completed withering. This method of evaporation is slow and easy to master.
(3) sunlight withering: the fresh leaves spread out on the bamboo mat or put into the sunlight, sunny days only 30 minutes can be, cloudy days depends on the degree of softness. In short, the standard of withering is: the shape of the leaf shrinks; the thick stalk loses water and is soft, not easy to break; the green flavor is reduced. Medicinal effect
The medicinal effect of bitter tea is obvious, Chinese medicine believes that it has the effect of dispersing wind-heat, clearing the head and eyes, and removing thirst, and can be used to treat headache, toothache, eye redness, fever and thirst, dysentery, etc. Modern pharmacological research has proved that bitter tea has the effect of dispersing wind-heat, clearing the head and eyes, and removing thirst.

Symptoms such as better prevention and treatment of the role of the disease, and is therefore much favored by the elderly. The middle-aged and elderly people are favored.
Lowering three high
Bitter tea when used as medicine, diabetes, hypertension, hyperlipidemia and other diseases have a very good therapeutic effect.
If used for lowering blood pressure, blood fat, diuresis, lowering fire, clearing the throat, treatment of gums, dental inflammation, etc., due to their physical and medical conditions, the concentration and length of time to drink is not the same, in general, the condition of the heavy, weight of the patient to drink the dosage of the corresponding relatively large, and the time to be a little longer, and vice versa. Generally speaking, the effect is faster if you drink a large concentration of the product, and slower if you drink a low concentration of the product. The effect is slow. Generally speaking, bitter tea when the concentration of medicinal use when the tea with 2-3 times, drinking method is: a day in the morning, afternoon and evening each bubble 2 ~ 3, has been drinking to no taste when chewing tea buds, through the gastric mucous membrane absorption drinking effect is more pronounced; if you feel that the condition has been alleviated, can be appropriate to reduce the concentration; such as feeling the condition has not improved significantly, can be appropriate to increase the dosage.
For patients with high blood pressure, high blood lipids, high blood sugar and other diseases, after lowering blood pressure, blood lipids and blood sugar by drinking Bittering Tea, the concentration can be reduced appropriately, but don't stop drinking it altogether, so as not to repeat the condition. If the concentration of Bittering Tea is appropriate, the blood pressure and blood fat can be lowered within 20 to 30 days. This is exactly where the value of Bittering Tea lies.
Bittering tea has a good preventive and therapeutic effect on the above mentioned diseases. Consumers usually drink bittering tea as a tea, so as to prevent the occurrence of various diseases and achieve the effect of health care.

Bittering tea can eliminate bad breath
The reason why tea can alleviate bad breath is because the polyphenols contained in tea can also kill the bacteria that cause bad breath, and the bacteria can create unpleasant volatile sulfur compounds, which is a major cause of bad breath. And the intervention of tea can inhibit this source of bad odor production. In addition to inhibiting the growth of this bacteria, the polyphenols in black tea also inhibit the unpleasant compounds made by these bacteria, a two-pronged approach that also keeps a person's mouth healthy and their breath fresh.
Tannins, tea polyphenols (catechins), tea pigments and many other biologically active components contained in tea can prevent the growth and reproduction of bacteria that cause oral odor. Whether it is black tea, green tea or oolong tea, this effect is very obvious. First of all, the tannins contained in the tea have a bactericidal effect, which can prevent bacteria from reproducing in the food residue, and can effectively prevent bad breath, so Bittering Tea is able to eliminate bad breath.
