National Geographical Indication Products. The region's unique natural environment conditions, long history of cultivation, traditional production of agronomy and processing techniques have formed the characteristics of Guangxi cinnamon skin thick, lustrous color, high oil content, spicy flavor, medicinal and spices. . The environment of Guangxi is located in the subtropical climate, especially in the vast hills and low mountains south of the Tropic of Cancer. It belongs to the southern subtropical climate. The annual average temperature is around 22 °C, the high temperature time is up to 180 days, and there is no frost or only Short-term light frost; sufficient rainfall, annual rainfall between 1500-2000 mm, high temperature and high humidity natural conditions and fertile red land, very suitable for cinnamon growth. Guangxi is the largest cinnamon producing area in the country. In 2009, it had a scale of 137,000 hectares. Planting history According to historical records, cinnamon was artificially planted during the Qin and Han Dynasties. In the late 1980s and early 1990s, the people of Guangxi Zhuang Autonomous Region implemented the development of subtropical dominant fruits and economic forests as “running well-off projects”, and cinnamon was listed as a key project to develop. Guangxi's southeastern Guangxi and southwestern Guangxi are suitable for the development of cinnamon-growing counties and cities, and set up a large-scale construction of cinnamon forest land in a planned and step-by-step manner. Thus, Guangxi cinnamon production has created a new chapter in history, and a batch of cinnamon-growing thousand acres of villages has emerged. Ten thousand mu villages (towns), more than 100,000 mu of counties and cities, showing a new pattern of contiguous development, continuous afforestation, and construction of large bases. Guangxi Cinnamon has built China's largest cinnamon production base. With an annual output of more than 30,000 tons of cinnamon and about 1,000 tons of cinnamon oil, the planting area and cinnamon production account for more than 50% of the country. Both the export of cinnamon and the processing and export of cassia oil account for more than 60% of the national total. Planting scale: In the late 1980s and early 1990s, the Guangxi Zhuang Autonomous Region People's Government implemented the development of subtropical dominant fruits and economic forests as “Ben Xiaokang Project”, and cinnamon was listed as a key project to develop. Guangxi's southeastern Guangxi and southwestern Guangxi are suitable for the development of cinnamon-growing counties and cities, and set up a large-scale construction of cinnamon forest land in a planned and step-by-step manner. Thus, Guangxi cinnamon production has created a new chapter in history, and a batch of cinnamon-growing thousand acres of villages has emerged. Ten thousand mu villages (towns), more than 100,000 mu of counties and cities, showing a new pattern of contiguous development, continuous afforestation, and construction of large bases. According to statistics from relevant departments, the area of ​​cinnamon in Guangxi in the late 1980s was only about 500,000 mu, but by 1996 the total area had reached 1.76 million mu, and the area in sixty years had increased more than threefold. By the year 2000, the area of ​​cinnamon forest in Guangxi had exceeded 2 million mu, reaching more than 2.5 million mu. Among the counties and cities with cinnamon forest land area of ​​300-400,000 mu, there are Pingnan, Fangcheng, Tunxi and Tengxian; there are more than 200,000 mu of Rongxian County and Cangwu, and there are more than 100,000 mu of Shangsi County. Guangxi cinnamon has built China's largest cinnamon production base. With an annual output of more than 30,000 tons of cinnamon and about 1,000 tons of cinnamon oil, the planting area and cinnamon production account for more than 50% of the country. The processing and export volume of cinnamon and cassia oil accounts for more than 60% of the national total.

Guangxi cinnamon quality technical requirements (a) species name. Red buds cinnamon, white buds cinnamon. (2) Site conditions. The low hills below 600 meters above sea level, the soil is sandy loam or loam, the soil layer is more than 1 meter deep, the soil is loose, the soil bulk density is 1.04 g/cm3 to 1.53g/cm3, the soil permeability and drainage performance are good, pH The value is 4.5 to 5.5. (3) Cultivation management. 1. Seedling: Seeds are collected from the mother plants with pure varieties, strong growth, and no quarantine pests and diseases. The nursery is selected from sandy loam near the water source, shaded, deep soil, loose and fertile soil, and well drained. Sowing from March to April, applying organic fertilizer when the seedlings have 3 to 5 true leaves. The standard for seedling emergence is: 2 years old bare root seedlings 60 to 80 cm high, ground diameter 1.2 cm or more, main root length 20 cm or more, lateral roots; 1 year old container seedling height 20 to 30 cm, ground diameter 0.4 cm or more, the main root is developed. 2. Transplanting and planting: (1) Planting period: The bare root seedlings have sufficient rain in spring, and the sprouts are not germinated before afforestation; container seedlings can be planted in spring or autumn. (2) Planting density: ≥9000 plants per hectare. 3. Tending management: (1) Watering seedlings: In the early stage of planting, seedlings are very susceptible to drought and dry seedlings, so it is necessary to pay attention to the water depending on the weather. When the drought is dry, every morning and evening, once every night, when there is a lot of water, it will not drip or drench. Found dry seedlings or lack of seedlings in time to replant. (2) Weeding and weeding: Weeding and weeding once in the year of afforestation, weeding twice in strips or blocky loose soil every year from the second year. The soil depth is 5 to 10 cm and does not harm the roots of the seedlings. 4. Fertilization: 1 to 3 years after planting, the young forest cinnamon is mainly applied with nitrogen fertilizer, and fertilized twice a year; after 4 years of planting, the cinnamon forest is formulated and fertilized, once every year from March to April and from August to September. 5. Pruning and thinning: Cinnamon woodland for the purpose of processing Guitong, starting in the second year after planting, pruning once a year in the autumn to ensure smooth and straight, and produce more cinnamon products. Cinnamon forest land mainly using steamed oil of branches and leaves should be topped in the third year after planting to promote branching and sprouting and increase branch and leaf yield. 6. Environmental and safety requirements: The use of pesticides, fertilizers, etc. must comply with relevant national regulations and must not pollute the environment. (4) Harvesting. Cinnamon can be harvested for the first time in 5 to 6 years. Harvesting has strict seasonality. After the spring sap begins to flow, the cassia is harvested. The special ring-cut hook knife and horn knives are first cut at a distance of 1.5 cm to 5 cm from the ground, and then ring at 35 cm. Cut a circle and cut a vertical line between the two secant lines to take the skin. The cassia is peeled up step by step, and finally the whole plant is harvested and harvested. The cutting mouth is close to the ground, the knife edge is smooth, the base is not torn, and the bud primordium is retained, which is beneficial to the germination renewal. (5) Processing technology.
