Abstract: Nitrogen is the necessary nutrient for the growth and development of tobacco. It has a certain influence on the chemical process of tobacco, such as chemical synthesis, energy conversion and signal transmission. Ammonium nitrogen and nitrate nitrogen are the main nitrogen forms of tobacco absorption, which have different effects on different parts of tobacco and different parts. The reasonable ratio of nitrogen is beneficial to the uptake of nitrogen and the improvement of tobacco leaf quality. In this paper, the effects of different nitrogen forms on the growth and development, growth, element absorption, photosynthetic characteristics and carbon and nitrogen metabolism of tobacco were reviewed. The effects of different nitrogen forms on the growth and development of tobacco were studied. Influence the relevant research to provide the basis.
