Main points of propagation of Dianshan tea

Dianshan tea can be cultivated in pot or open field, but there needs to be a certain temperature difference in the process of cultivation. Dianshan tea can survive the winter naturally in the south of Huaihe River and can generally withstand the low temperature of-8 ℃. Artificial propagation of Camellia yunnanensis can be done by sowing and grafting.

Dianshan tea

Dianshan tea is generally propagated by seed propagation and relying on grafting. The fruit is picked in autumn, dried in shade, and the seeds are watery, oily and short-lived. After being taken out, the seeds should be sown on the mountain woodland with a row spacing of 1 to 1 meters, and 3 seeds will be planted in each hole to germinate in the spring of next year to strengthen tending management. Or store the seeds in wet sand, sow them in the seedbed in the early spring of the following year, germinate in about 20 days, and transplant them up the mountain in the rainy season from May to June when the seedling height is 20ml / 30cm. Using camellia (details) as rootstock and grafting with Dianshan tea in about 100 days, the lower end of the scion of Dianshan tea can be cut off from the mother tree to form a new plant. The cuttage method can also survive, but the survival rate is low. Excellent clones can also be propagated by tissue culture.

Key points of cultivation of Dianshan Tea

Dianshan tea originated in Yunnan, China, with a wide variety of varieties, it can be said to be a more distinctive flowering plant among all kinds of safflower camellia produced in Yunnan. Dianshan Camellia is similar to Camellia heterophylla, but it is different from this species in that the leaf base is rounded, the apex is slightly obtuse, the flower is double, and the stamens become less. It is only a cultivated variety. What problems should be paid attention to in potted Yunnan Camellia? The editor will sum it up for you.

Potted Camellia yunnanensis can be planted in different flowerpots according to the growth of seedlings. When putting on the basin, first use 3 tiles of 2 murals and place them on the drainage hole at the bottom of the basin. Covered with a layer of coarse rotten soil or ceramsite, plus sheep, horn fragments and other aggregate base fertilizer, the base fertilizer layer generally does not exceed the basin height of 1/3. Add organic fertilizer such as rotten pig manure to the base fertilizer layer. Finally, fine laterite was added to cover the soil, and the plant was planted to avoid direct contact with organic fertilizer. Medium-grained soil mixed with rotten leaves and aggregates was placed around the root system, and the soil was compacted, then covered with fine soil mixed with rotten leaf soil, and the top layer was covered with broken tiles as a protective soil layer. Potted plants need to change pots every 2-3 years, and it is appropriate to change pots when the new branches become lignified and turn brown slightly. Changing pots too late will affect the differentiation of flower buds, and too early will affect the growth and development of new branches. Stop watering for 3 days before changing the basin to make the basin soil dry. Easy to "take off the basin". Try to ensure the integrity of the earth ball when taking off the basin. And remove the pests, rotten roots and diseased roots at the bottom. The basin pH is 5: 5. About 5 is better.

The most suitable temperature for growth and development of Dianshan tea is 18 ℃ 24 min. Over 32 ℃. Growth was inhibited: freezing injury occurred when the growth was below-5 ℃. Different varieties of Dianshan tea have different resistance to low temperature, such as hemp leaf peach red, peony tea, hate Tiangao, boy noodles and so on. The flower buds will fall off at 0 ℃, so the corresponding cooling and anti-freezing measures should be taken in the process of cultivation.

In potted Camellia yunnanensis, the soil is required to maintain a certain degree of humidity. in practice, fingers are often used to hit the basin wall, the sound is brittle when the soil is dry, and the sound is more stuffy when the soil is wet. The watering time depends on the change of temperature. When the temperature is high, water it in the morning or afternoon when the temperature is low. Camellia yunnanensis planted in the ground should pay special attention to watering root water and ensuring sufficient moisture in the growing period of new shoots before flowering. The rest shall be irrigated according to different weather conditions. In the dry season, irrigating 2 ml / month for 3 times, it is suitable to use the wet and permeable tillage layer.

The Propagation method of Dianshan Tea the efficacy and function of Dianshan Tea

The shady tea in Dian Mountain has broad leaves, large flowers and a wide variety, so it is cultivated in Yunnan. "Dianshan tea culture method" has been understood, then how to reproduce Dianshan tea? Has and the effect and the function? Let's learn about it next.

A complete set of propagation methods of Dianshan tea

1. Cutting method: this method is the most simple, and the best cutting time is September, and it can also be done in spring. Select the well-growing, semi-lignified branches, remove the basal leaves, retain the upper 3 leaves, and cut them into bevel with a sharp knife. Soak 200ppm into 500ppm indolebutyric acid for 5 to 15 minutes, dry and insert into sand basin or vermiculite basin. After insertion and watering, the wound healed in about 40 days and took root in about 60 days.

2, rely on the method: choose appropriate varieties such as Camellia oleifera as rootstock, rely on the valuable camellias. The pick-up time is usually between Ching Ming Festival and Mid-Autumn Festival. First plant the rootstock in the flowerpot, cut off about half of the joint with a knife, and the incision should be smooth. Then close the section of both sides, wrap it with plastic film, water the rootstock twice a day, and heal after 60 days. At this time, it can be planted in the shade of trees to avoid direct sunlight.

3. Leaf cutting method: mountain mud is used as cutting substrate, which can be mixed with 1/3 river sand to facilitate ventilation and drainage, and the matrix is stored in a tile basin, and then cut in a basin. Leaf insertion is best carried out in the rainy season, take one-year-old leaves as leaf insertion material, too old is not easy to root, too young and easy to rot. Insert about 2 cm into the soil, press the soil after insertion, pour enough water, and then put it in a cool and ventilated place. Generally, it can take root in 3 months, and it can sprout and branch in the next spring.

II. The efficacy and function of Dianshan Tea

1. The medicinal efficacy of Dianshan tea: the seed of Dianshan tea has a high oil content, so it can be used for edible, it has a very significant effect, as well as high nutritional value, which is very good for our health. Edible and has superior medicinal and nutritional quality than other edible oils, and its effect on human health is much higher than that of ordinary edible oils. regular drinking Dian Camellia can protect our health.
