Origin and habit

Camellia japonica is an ancient plant, which is extremely rare and its distribution range is extremely narrow. 90% of the wild camellia in the world is only distributed in Lanshan branch of Shiwan Mountain in Fangchenggang City, China, and grows below 700 meters above sea level, especially within the range of 200-500 meters above sea level. The lower limit of vertical distribution is about 20 meters above sea level. For example, in the coastal hilly platform near Dawangjiang, Fangcheng County, there is still camellia distributed. The upper limit of vertical distribution can reach 890 meters above sea level. For example, you can still see some camellia with small petals in Natao Mountain in Ningming County, which is a rare and precious plant in the world. It is one of the eight national first-class protected plants in China and belongs to Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora. Known as the magical oriental tea abroad, it is known as the "giant panda in the plant world" and the "queen of tea family". 1960, Chinese scientists first discovered a camellia, named camellia, in Nanning, Guangxi. The discovery of camellia caused a sensation in the global horticulture and the press, and was highly valued by horticulturists at home and abroad. It is considered to be the best original material for cultivating camellia chrysantha varieties.

Camellia likes warm and humid climate, well-drained acidic soil, cool at seedling stage and sunshine after flowering. The requirements for soil are not strict, and it can grow in slightly acidic to neutral soil. Resistant to barren, but also like fat. Strong waterlogging tolerance.

Propagation and cultivation

Propagation by sowing, grafting and cutting. The cultivated soil should be breathable without water accumulation. Shading sheds should be built at seedling stage, potted plants should be planted in the northern part of the Yangtze River basin, and greenhouses should be moved in winter. Camellia is a temperate and hot plant, belonging to tropical tree species, which requires high heat, but there are certain differences between species and different growth stages. The tropical climate introduced into Central Asia can grow and develop normally. Camellia has the characteristic of liking humidity. Species have different water and humidity conditions in different growth periods, and have higher requirements for vegetative growth periods. However, too much rain during flowering is easy to lead to flowering. Camellia cannot stand direct sunlight, so it is a shade-loving and shade-tolerant plant. The required illumination is generally 320-600Lax, but there are differences among species. Under different light conditions, the ability of plant growth, fruiting and regeneration is positively correlated with shading. Camellia plants can be divided into two categories: acid-resistant Camellia and calcium-resistant Camellia. Camellia japonica can't be seen in two different types of soil under natural conditions, but under artificial introduction and cultivation, rocky mountain varieties can grow in acidic soil. The requirements for ash and elements of tea trees grown in two different soils are unacceptable.

App application

Golden camellia is golden in color, and most varieties are waxy and lovely. The flower patterns are cup-shaped, pot-shaped, bowl-shaped and dish-shaped, with diverse shapes and elegant appearance. It is known as the "Queen of Tea Family" in the camellia group. Subtropical areas can be planted under evergreen broad-leaved trees or viewed in shade sheds.

economic value

Camellia chrysantha also has high economic value. Its flowers are not only ornamental, but also used as medicine, which can treat women's hematochezia and menorrhagia, and can also be used as edible dyes. Besides making tea as a drink, leaves also have medicinal value. Camellia japonica has obvious effects on regulating blood lipid, blood sugar and cholesterol, enhancing immunity, improving various uncomfortable symptoms caused by hypertension, resisting bacteria and inflammation, clearing away heat and toxic materials, inducing diuresis to reduce swelling, enhancing liver and kidney vitality, preventing arteriosclerosis, preventing cancer and inhibiting tumor growth. After investigation, Camellia chrysantha has the functions of refreshing the brain, clearing liver and purging fire, clearing away heat and toxic materials, and nourishing vitality. Pharmacological records of Camellia japonica can be found in Outline of Guangxi Ethnic Medicine, Guangxi Chinese Herbal Medicine Standard, Proceedings of International Symposium on Camellia japonica in Fangcheng, China, Proceedings of International Symposium on Camellia japonica in Guangxi, China, China Zhuang Medicine and Dictionary of Medicinal Plants.

Health function

1, anticancer effect:

Selenium: It can prevent the formation of free radicals. Can destroy the epoxide formed by carcinogens in the body. Sodium selenite can inhibit the DNA synthesis of mouse hepatocellular carcinoma cells and reduce the DNA synthesis of human rectal adenocarcinoma cell line HR 8348. Selenium can also selectively interact with various biochemical metabolism of tumor cells to achieve anti-cancer effect.

G: As we all know, all organs of the human body have their fixed potentials. Cancer cells have great potential and great changes. Ge may control and inhibit the potential of cancer cells through dehydrogenation.

Mn: It can resist chemical carcinogenesis-carcinogenesis of benzopyrene.

Tea polyphenols: Experts from Japan Cancer Society believe that it can control the proliferation of cancer cells.

2. lower cholesterol and. Role of szlig lipoprotein:

V: It is related to the metabolism of lipids and cholesterol. It can promote hematopoietic function and significantly reduce plasma cholesterol. The serum triglyceride and cholesterol content of V-deficient animals increased.

Mn: It can improve the lipid metabolism of patients with atherosclerosis. To prevent experimental atherosclerosis.
