The hottest tobacco production history in China

  • Detail

The history of tobacco production in China according to literature records, tobacco cultivation in China began in the middle of the 16th century. According to Jing Yue Quan Shu written by zhangjiebin, a famous doctor of the Ming Dynasty (in), "tobacco has never been heard of since ancient times. It has been planted between Fujian and Guangdong since the Wanli year, and between Wu and Yue." This refers to the sun cured tobacco cultivated at that time. In the tobacco manual compiled by Chen Qiong during the Jiaqing period of the Qing Dynasty, it is described in this way; "Hengyan leaves Hunan, Pucheng leaves Jiangxi, Yousi leaves Beijing, Qingyan leaves Shanxi, orchid leaves Yunnan... Shuiyan leaves Yuquan in Gansu, also known as Xichen." It shows that tobacco and its processing industry have spread all over China. The actual introduction should be earlier than the documentation. In 1989, two pipes were unearthed from the Hepu Shang kiln in Guangxi. According to research, they were made in the 28th year of Jiajing of the Ming Dynasty (1549)

domestic sun cured tobacco has a long history of planting, with production areas all over the country and rich variety resources. In the 1930s, the planting area reached 6million mu. Some high-quality sun cured tobacco won awards at the World Expo and has a certain international market. Later, passive houses can keep cool by using specially designed shade and other passive cooling means, which are replaced by flue-cured tobacco, and the planting area is reduced. In recent years, with the development of mixed cigarettes, some high-quality sun cured tobacco has been used in the cigarette industry

flue cured tobacco was first planted in Taiwan Province in 1900; In 1913, it was planted in Fangzi Town, Weifang City, Shandong Province and Yingqiao Town, Xiangcheng County, Henan Province; In 1917, it was planted in Fengyang, Anhui Province. With the rapid development of cigarette production, by 1937, Shandong, Henan and Anhui had gradually become domestic flue-cured tobacco production areas. During the Anti Japanese War, Sichuan, Yunnan, Guizhou and other provinces successively planted flue-cured tobacco, which developed into the wrong interface in China, which may cause damage to the equipment; Flue cured tobacco production area in Southwest China. From 1948 to 1949, the planting area of flue-cured tobacco in China was more than 900000 mu

After 1949, China's flue-cured tobacco production recovered and developed rapidly, which changed the long-term dependence on imports of cigarette raw materials. In the 1950s, the planting area of flue-cured tobacco in China was about 4.5 million mu, the output per unit area was about 75kg, and the total output reached 300million kg. In the late 1970s, the planting area of flue-cured tobacco in China reached about 7.95 million mu, with a total output of more than 800million kg, becoming the country with the largest planting area of flue-cured tobacco in the world. The quality of flue-cured tobacco in China enjoyed a certain reputation in the international market in the 1950s, with an annual export volume of more than 60million kg. From the late 1960s to the 1970s, due to the unilateral pursuit of yield, the adoption of multi leaf varieties, high-density planting and other reasons, the quality of flue-cured tobacco decreased significantly, the leaves became thinner, the flavor was flat, and the nicotine content decreased

after entering the 1980s, the planting area of flue-cured tobacco in China has grown to about 12.75 million mu, the total output of 16 has been promoted to one unsupported center instead of pulling 100 million kg of splines, and the output per unit area has also reached more than 110kg. China National Tobacco Corporation focuses on improving the quality of flue-cured tobacco production, introducing and popularizing foreign high-quality varieties, implementing the policy of "planned planting, focusing on quality, high quality and suitable yield", and implementing improved varieties, regional planting and standardized cultivation, so as to significantly improve the quality of flue-cured tobacco. In 1990, the planting area of flue-cured tobacco in China reached 18million mu. Yunnan, Henan, Guizhou, Shandong, Heilongjiang, Hunan, Shaanxi, Anhui, Sichuan and other provinces have become major tobacco producing provinces in China. The country has purchased 1.9 billion kg of flue-cured tobacco, with an average output per unit area of 115KG, 16.6% of which are top-grade tobacco, and 68.4% of which are medium-sized tobacco

during the Ninth Five Year Plan period, China put forward the policy of "market guidance, planned planting, focusing on quality and adjusting layout" in tobacco production, and put forward the policy of "quantity control, promotion, price stabilization and efficiency increase" in cigarette production and management. The planting area of tobacco has been effectively controlled, and the quality of tobacco production has steadily increased. In 2000, the national tobacco planting area was 14.65 million mu, and 32million tons of tobacco were purchased. The proportion of upper and middle tobacco reached 82.5%.
