钾素营养对烤烟烟叶品质影响的研究进展

Advance on Affection of Tobacco-leafs Character by Using Potassium Nutrition

烟草是喜钾作物,增施钾肥可提高烟叶含钾量,提高烟叶的生理活性,提高烟叶内在品质,增加烤烟的抗逆性,提高产量及其质量,烟叶的含钾量直接影响烟叶的香气质、香气量、燃烧性和持火力等.

Tobacco is one of Chinese economic-crop. It is cultured in much territory. The production of tobacco has been one of an important portion of revenue income in those areas where culture tobacco in China. It helps those people who culture tobacco to release from poverty. Tobacco is a crop who is like of Kalium.Adding use of Cilium-fertilizer can increase Kalium-content in tobacco-leaf, increase physiologic activates and inherent quality of tobacco-leaf, inhance its application of adversity, increase yield and quality of tobacco. The Kalium-content of tobaccoleaves affect tobacco-leafs perfume quality and quantity, combustibility and capability of keep fire and so on. Adding use of Cilium fertilizer can increase ratio of utilizing light and energy, inhance accumulation of content, delay its caducity and accelerate tobacco-leafs physiologic raping. There is an interaction between Cilium (K) and Nitrogen (N), adding use of N can increase Cilium content of tobacco-leaf. It can increase 6.83%. Using of KNO3 two times is better than one time in increasing absorption of Kalium.Potassium nutrition has important use in production of tobacco.
