Golden tea cultivation summary:

1, to create a suitable environment, the golden tea was born in the semi-shade, semi-cool, humid environment, and the need for regular ventilation, especially in the north need to do this. In addition to the glass heated cellar equipped with heating boilers, heaters, but also added a homemade fog machine, ventilation fans and other facilities.

2, the use of proportional preparation into the pine needle soil, and gradually remove the south to bring the "yellow mud".

3, watering flowers with water must be added every time 1% of ferrous sulfate, so that the water always maintain a certain weak acidity.

4, in addition to a well-ventilated environment, but also to give it a regular "physical exercise", every 2 weeks to blow the wind, blowing the wind to wind evenly. The purpose is to promote its metabolic balance through "exercise", normal development.

5, temperature control, the temperature difference should be 7 ℃ to 10 ℃, cellar temperature at 20 ℃, four or five hours after the shade cloth down, then ventilation.

6, fertilizer, a diluted sour milk, this method does not have to be fermented can be used directly, another traditional method is fermented soybean cake water. Fertilizer can be applied once a month.

Propagation:

1, seed propagation: the golden tea fruit is generally ripe in early to mid-October, cracked in late October, the seed is ripe with no post ripening dormant period. Seed propagation to autumn sowing is appropriate, in early to mid-October, the harvested fruit placed in the indoor ventilation in the shade, to be the capsule dehiscence to take out the seeds, and then immediately sowing. If you can not fall sowing, need to store the seeds in wet sand, until the following February for spring sowing.

2, cuttings reproduction: golden tea cuttings reproduction in April to early May, can also be carried out in September in the middle and late. Spike selection of the crown of the external tissues full, complete leaves, leaf buds full and free of pests and diseases of the year half-mature branches. Spike length is generally 15 cm, the apex left 2 leaves, the base with the heel. With IBA 300ppm treatment of branches 5 hours, according to the plant spacing 10 ~ 14 cm × 3 ~ 4 cm specifications cuttings in the seedbed, spike into the soil depth of 3 cm or so. The key to the survival of tea cuttings is to maintain sufficient humidity in the pre-seedling period, avoid direct sunlight, and control the temperature at about 25 ℃. Spray water diligently, so that seedlings are often covered with a thin film of water. 1 month later, when the new roots grow, gradually increase the sunlight, accelerate the lignification of tea seedlings.

3, grafting reproduction: the golden tea grafting reproduction is divided into bud seedling rootstock grafting and semi-mature branch grafting. Bud seedling rootstock grafting. Rootstock can choose ordinary single petal camellia and oil camellia. First, the rootstock seed sown in the sand bed, when the seedling grows to 4 ~ 5 cm can be grafted. Before grafting, dig the rootstock buds, remove the sand, in its cotyledon above 1 ~ 1.5 cm short cut, and cut off the root tip part, so that its total length of 6 ~ 7 cm; select the growth of good semi-woody branches for scion, cut it into a wedge shape, and put it into a wet towel to keep it moist. When grafting the bud seedling along the cotyledon suture line will stem longitudinal split a cut, the depth of the scion cut by the slope of the same, will cut the scion quickly inserted into the rootstock split, aligned with the rootstock on one side of the formation of the layer, with a plastic film band tied tightly. Then the grafted seedlings will be connected according to 8 × 2 cm spacing planted in fertile, loose sandy soil seedbed. After planting in the seedbed trellis with plastic film insulation. General 10 ~ 15 days grafted seedlings interface began to heal, 20 ~ 25 days or so can be uncovered at night film. Subsequently, gradually strengthen ventilation, increase light, to the new buds sprouting later, all remove the film.

Semi-mature branch grafting. Usually the use of coarse species of camellia or oil tea adult seedlings as rootstock. Diameter of 1 cm or more rootstock branches, the use of pulling the skin, that is, in the appropriate part of the rootstock, on the left, right each carved a knife, deep to the xylem, and pull down the skin, the scion will be attached to the rootstock pulling the skin on the inside, and then pull the skin on the scion, wrapped in a plastic band tied, revealing the tip of the buds, covered with a plastic bag to keep wet. 1 month later, to be scion draws out a new branch, and gradually lignification, lifting the tie. If the thickness of the rootstock and scion is similar, it is appropriate to use the abdominal method. The success of half-ripe branch grafting depends mainly on the control of the temperature of the seedbed and the choice of grafting period. Grafting suitable temperature of 25 ~ 30 ℃, grafting appropriate period of May to August, when the rootstock skin is easy to pull open, grafted seedlings interface healing fast, high survival rate.

4, tissue culture: gold tea embryo culture, cotyledon culture, stem tip and single bud culture has been successful. The results of the study showed that the test tube seedlings induced bud production and rooting with the location of the material taken, inorganic salt concentration, vitamins, sucrose, growth regulators, light and other factors. Embryo culture. Embryos were taken at the immature stage of young fruits and cultured in ER and MS medium with additional components such as 0.5-1 mg/L 6-BA, 0.01 mg/L NAA, 6%-8% sucrose, and 500 mg/L hydrolyzed lactic protein, etc. Roots grew in about 1 week, and the epimeric axes sprang up and drew new shoots after 2 weeks. Cotyledon isolation culture. The cotyledons of Camellia sinensis are good materials for inducing embryoid bodies, especially the part close to the hypocotyl, with a high frequency of 15% to 25%. The cotyledons were cut into 0.5 mm size at the time of induction, and the induction medium was 1/2 MS with additional 0.2 mg/L 6-BA and 0.2 mg/L NNAA components. During the induction process, both adventitious buds and pseudobulbs appeared. Pseudopearl buds have a strong ability to hyphalize, and by using pseudopearl buds, embryos, indeterminate buds and pseudopearl buds can be induced to produce again. Stem tip and single shoot culture. Stem tip and single bud culture is an important way of rapid propagation of Camellia sinensis, which is easy to take, has a high proliferation rate and is genetically stable. The young stem tips and single buds of the current year were used for exoculture, and the medium was MS with additional 6-BA or KT.It was shown that the proliferation number of stem tips and single buds increased with the concentration of 6-BA, but the malformed seedling rate was high and poor when the concentration of 6-BA was up to 5.0 mg/L.6-BA 2.0 mg/L was used in conjunction with KT 0.5 mg/L, and the in vitro seedlings had a robust growth and low malformed seedling rate, which was the best way for inducing the growth of Aurelia. It is an ideal growth regulator ratio for inducing proliferation.

Flowering management:

Golden tea is usually planted 3 to 5 years before flowering, usually in July to August each year, yellow buds, this time you can remove some of the weak buds, inward buds, too dense buds and deformed buds, so that you can focus on nutrients, so that the distribution of flowers is reasonable, bloom larger, and prolong the flowering period. By November when the Golden Flower Tea is fully open, until March of the next year, the blooming period of 1 to 2 months.

Pest control:

The common diseases of adult Camellia sinensis are anthracnose, sooty disease, leaf blight, bud blight, etc. Anthracnose is a common disease of Camellia sinensis, and the disease spot starts from the tip of the leaf or the edge of the leaf, and the spot is irregular, and there is often a black dot on it, and the boundary between the disease and the healthy part of the disease is obvious. Usually use 70% metribuzin 800 times diluted solution in the early stage of the disease for foliar spraying, 5 ~ 7 days once, three times in a row. Spraying amount is 60 kilograms per mu. Sooty disease symptoms manifested as a coal stain on the leaves, the disease also harms the branches and shoot tips, serious branches and leaves covered with a black layer of coal stains, preventing the plant from normal photosynthesis. The disease-inducing pests are mainly aphids, which can be prevented and controlled by spraying with 50% of Lego emulsion 1000 times. Tea budworm, leafrollers, tea moths and other common pests of Camellia sinensis, tea aphids and leafrollers can make Camellia sinensis leaves curl and shrivel, unable to stretch. Tea poisonous moth will bite the leaves into the missing pieces, or all eaten, seriously affecting the growth of the plant, in the prevention and control should be carried out early, you can use high-efficiency low-toxicity and low-residue chrysanthemum emulsion 800 times for spraying.

Extended information

Golden tea belongs to the family Camelliaceae, Camellia sinensis, with tea, camellia sinensis, Camellia sinensis, oil tea, tea plums and so on for twins, is one of the national level of protection of plants . Golden flower tea flowers golden yellow, dazzling, as if coated with a layer of wax, crystalline and oily, seems to have a translucent feeling. Golden tea is born singly in the leaf axils, when the flowers bloom, there are cup-shaped, pot-shaped or bowl-shaped, delicate and colorful, beautiful and elegant. Previously, people have not seen the species with golden flowers. Golden tea by the Chinese botanist Zuo Jinglie in July 29, 1933 in Guangxi Fangcheng County, Arthraxon Township, A Lei Ai first found in 1948 by China's botanist Chi Jingwen officially named "Camellia nitidissima C.W. Chi". Foreign countries called the magic of the Oriental magic tea, known as the "plant giant panda", "tea queen".

The discovery of the Golden Flower Tea filled the gap of the tea family without golden yellow flowers. Its waxy green leaves are crystal clear, the petals are transparent, firm and smooth, spotless; buds round, gold color; petals overlap dense, bright and colorful, decorated with jade leaves and agarwood branches, elegant, golden petals and jade stamens, beautiful and pleasant, pleasing to the eye, its ornamental value is unparalleled.

Golden tea has a special color genetic DNA, its reproduction is difficult to be copied. The use of high-tech solutions for rapid reproduction of many kinds of excellent seedlings of Camellia sinensis live gene, to overcome the difficult problem of low survival; breakthroughs in the growth of Camellia sinensis slow production of low key technologies, significantly increase the production of large-scale planting of Camellia sinensis; deep development of a new generation of Camellia sinensis world-class health care products for the benefit of human health, are very important scientific research value.

According to the Chinese Center for Disease Control and Prevention of nutrition and food safety, Guangxi Zhuang Autonomous Region Center for Disease Control and Prevention, Guangxi Zhuang Autonomous Region Health Supervision and Inspection Center, Beijing Center for Disease Control and Prevention of Center for Nutrition and Food Safety, Guangxi Zhuang Autonomous Region Center for Analytical Testing and Research Center, Guangxi College of Traditional Chinese Medicine, Guangxi College of Agriculture Experimental Center and other authoritative institutions test shows that: goldenseal tea is a non-toxic level, Contains more than 400 kinds of nutrients, no toxic side effects. Rich in tea polysaccharides, tea polyphenols, total saponins, total flavonoids, tea pigments, caffeine, protein, vitamin B1, B2, vitamin C, vitamin E, folic acid, fatty acids, B-carotene, and other natural nutrients; gold tea contains theanine, threonine and dozens of amino acids, as well as a variety of organic germanium rich in natural health effects on the human body has an important role in (Ge), selenium (Se), molybdenum (Mo), zinc (Zn), and other natural organic substances. Mo), zinc (Zn), vanadium (V) and other trace elements, and potassium (K), calcium (Ca), magnesium (Mg) and other macroelements.
