How to Grow Tobacco So It Tolerates Drought? An Introduction to Cultivation Methods
How can tobacco be grown to tolerate drought? Tobacco has high water requirements during its growing period, and drought stress will significantly affect tobacco leaf yield and quality. China is a country short of water resources, with an uneven distribution of water resources in time and space. In recent years, some tobacco-growing areas in China have suffered severe drought year after year, and the frequency and scope of impact of drought disasters have expanded, while their duration and the losses suffered have increased, exerting a great impact on China's tobacco leaf production. Solving the drought problem tobacco faces during the growing season by building water conservancy facilities for irrigation has a good effect, but the cost is too high, it is difficult to achieve supporting irrigation for all tobacco fields in the short term, and in some tobacco-growing areas it is not advisable. Therefore, at present, adopting relevant agronomic measures to improve the water demand conditions for tobacco plant growth is still the main approach.
