Cigarettes depend on the type of tobacco. Different varieties of tobacco seeds produce different fruits. The following is a detailed explanation: There are currently 66 varieties of tobacco confirmed by botanists. However, there are only two varieties cultivated and eaten by people: one is common tobacco, also called Nicotiana tabacum, which is an annual or two- or three-year-old herbaceous plant. This tobacco is best grown in warmer areas. One is Nicotiana tabacum, also known as Nicotiana tabacum, which is an annual or biennial herb. This kind of tobacco has strong cold tolerance and is suitable for cultivation in low temperature areas. In addition, there is a kind of tobacco cultivated by Chileans, which has green leaves and white flowers. It is very beautiful. It is only used as an ornamental flower abroad and is generally not included in the scope of tobacco. Most of the tobacco cultivated in our country is ordinary tobacco, except for a small amount of Nicotiana tabacum in the north. In most places, people eat tobacco leaves, so as a commodity, tobacco is also called tobacco leaves.
Tobacco can be divided into many varieties, and the United States is currently divided into five major categories. According to the variety characteristics, cultivation conditions, preparation methods and main uses of various tobaccos cultivated in our country from ancient times to the present, they are mainly divided into the following six categories:
Air-cured tobacco: This variety is produced in a wide area and has a long history of cultivation. The oldest, almost all over the world. This is the earliest tobacco variety introduced into my country. The tobacco discovered in the early stage is like Nicotiana tabacum, collectively called sun-cured tobacco, commonly known as native tobacco. The method of processing into tobacco products is also relatively simple. Generally, mature tobacco leaves grown in the field are picked and hung in the eaves to dry in the sun. , hand-made equivalent to today's cigars and cut tobacco, and smoked with simple smoking tools. There are two production and consumption methods: one is that farmers grow and smoke it themselves, or sell a small amount; the other is the large-scale production of air-cured tobacco for the manufacture of tobacco products, such as cigars, cut tobacco, snuff, chewing tobacco, etc. . Air-cured tobacco can also be used in small quantities to produce cigarettes. However, it is spicy, irritating, and has a narrow consumption range. After research and trial planting, many superior tobacco leaf varieties have been successfully cultivated. At the same time, the quality of the original sun-cured tobacco has been improved, and local dried tobacco with unique characteristics has been formed.
Frue-cured tobacco: Originated in Virginia, USA, internationally known as Virginia-type tobacco, also known as American tobacco. Since this kind of tobacco leaves are heated and baked with a fire tube in the curing room, the exact name is flue-cured tobacco. After the tobacco leaves are baked, the leaves will be golden in color, bright in luster, and fragrant.
It is The main raw material for the production of cigarettes in countries around the world. Its output accounts for more than 40% of the total global tobacco output. The main raw material of flue-cured cigarettes is flue-cured tobacco, and other types of tobacco products also need to use flue-cured tobacco in the production. The main producing countries of flue-cured tobacco are: China, the United States, Canada, India, Zimbabwe and other countries. China's flue-cured tobacco production accounts for more than 80% of the total tobacco production. Flue-cured tobacco production is mainly concentrated in Yunnan, Henan, Guizhou, Shandong and other provinces.
Burley tobacco: Burley tobacco is native to the United States and is named after the stems and veins of the leaves are milky white. It is a kind of dark brown drying tobacco. The preparation method is like building a drying grid that can control the temperature and humidity, and hanging the mature tobacco leaves in the drying grid to prepare and dry. This kind of tobacco leaves has a strong aroma and high nicotine content. It is the main raw material for the production of mixed cigarettes. Countries that grow burley tobacco include the United States, Japan, Brazil and other countries. From 1956 to 1966, my country successively experimented with Shandong, Henan, Anhui and other provinces. Since the 1980s, Burley tobacco has been planted in Hubei, Chongqing and other places. The quality of tobacco leaves has improved and has been used to produce hybrid cigarettes.
Oriental tobacco: Oriental tobacco leaves are mainly produced in Turkey, Bulgaria, Greece, Thailand and other countries. It is a special variety with small leaves and high aromatic substances. It is a formula tobacco leaf for the production of mixed cigarettes. It can also be used in larger quantities to produce a flavored cigarette. This type of cigarette is produced in Eastern European countries such as the former Soviet Union and Bulgaria. However, the yield of oriental tobacco leaves is low, generally about 40-50 kilograms per mu, so the price is high, and only a small amount can be used to produce mixed cigarettes. The global production of this tobacco is small.
Cigar: This does not refer to the finished cigars rolled into one piece, but to the raw material for making cigars - cigars as tobacco leaves.
The raw material tobacco leaves for making cigars are very strict, and they are divided into three types: wrapper tobacco, bunch leaf tobacco and core leaf tobacco. Among them, the most stringent requirements are for leaf-wrapped tobacco. The leaves should be cultivated to be thin and light, with fine veins, fine tissue, strong elasticity and tension, and uniform and shiny color. This kind of leaf tobacco is generally cultivated specially, preferably in the shade. After picking, it is dried in the room. It is a type of air-cured tobacco. The main producing area of ??leaf tobacco in my country is Sichuan, and the quality produced in Tongxiang, Zhejiang is the best. Many of the sun-cured red tobacco produced in my country can be used as raw materials for cigar bundle leaves and core leaves.
Huanghuayan: Huanghuayan and the above-mentioned five kinds of red flower smoke belong to different species in plant classification, so there are big differences. Its plants are shorter than those of red tobacco, with a shorter growth period and stronger cold tolerance. Therefore, the areas where yellow flower tobacco is grown in my country are all in the north. Among them, the famous ones include Lanzhou yellow flower tobacco (ie Lanzhou hookah), Northeast Toad, and Xinjiang Yili Mohe tobacco. Also known as horse smoke). Most are processed into pipe tobacco and hookah.
In addition, in recent years, Chinese agriculturists have successfully researched and bred a new type of "medicated cigarette", which was successfully bred through distant hybridization of medicinal plants and tobacco. For example, the medicated cigarette breeding research team of Shanxi Agricultural University has successfully cultivated 9 kinds of "medicated cigarettes" with Chinese herbal ingredients such as ginseng, astragalus, honeysuckle, and mint. These "medicated cigarettes" can reduce the content of harmful substances in cigarettes and have certain curative effects on certain human diseases. They are a promising new type of tobacco products. Currently, there are 66 varieties of tobacco confirmed by botanists. However, there are only two varieties that are cultivated and eaten by people: one is common tobacco, also called Nicotiana tabacum, which is an annual or two- or three-year-old herbaceous plant.
