What is the difference between tobacco and tea?
Tobacco: It belongs to the genus Nicotiana in the family Solanaceae of Angiospermaceae;
Tea: It belongs to the genus Camellia of Theaceae of Angiospermaceae.
2. Different morphological characteristics
Tobacco: Tobacco is a thermophilic crop and sensitive to temperature. Different temperature conditions have great influence on the quality and yield of tobacco. The temperature requirement of high-quality tobacco leaves in the growth period is lower in the early stage and higher in the later stage. When the average temperature of the day is higher than 35℃, the growth of tobacco plants is inhibited, the leaves become thicker and harder, the nicotine content is too high, and the quality becomes worse. Low temperature can promote the early development of tobacco plants, but different varieties have different responses to low temperature. For all types of tobacco, the temperature below 65438 03℃ is generally not desirable.
Tea: The natural conditions of tea planting include topography, climate and soil type. The terrain is mainly hilly, and the drainage conditions are good. Abundant precipitation, small annual temperature difference, large temperature difference between day and night, long frost-free period and good lighting conditions are suitable for the growth of various types of tea trees, especially for the growth of big-leaf tea trees.
3. The distribution range is different.
Tobacco: Native to South America. China is widely cultivated in northern and southern provinces. Widely planted in every corner from 55 north latitude to 40 south latitude, but its most suitable planting area is very narrow.
Tea: Wild varieties are distributed in the mountainous areas of the provinces south of the Yangtze River in China. They are small trees with big leaves, usually more than 10 cm long. For a long time, after a lot of cultivation, the coat color and leaf shape have changed greatly.
