Method for reducing burley tobacco nicotine

Abstract

The invention discloses a method for reducing burley tobacco nicotine, which comprises the following steps: selecting a tomato seedling as a stock and a burley tobacco seedling as a cion, grafting by adopting a cleft graft method, horizontally cutting off the upper half part of the stock that is 8 cm to 10 cm from the soil surface, and vertically downwards cutting a cut with the length of 1 cm; cutting off the upper half part of the cion from a parent, grinding two sides of a stem into wedge-shaped structures with the length of 1 cm, vertically inserting the wedge-shaped structure into the stock, fixing by a grafting clip, and moving into a coalescence curing chamber. The synthesis of the burley tobacco rooted nicotine is controlled manually through a grafting manner, the burley tobacco nicotine is reduced remarkably, and the problem that the content of the burley tobacco nicotine is too high is solved effectively. As burley tobacco and tomatoes are classified as solanaceae, the burley tobacco and the tomato have good affinities, and the grafting success rate reaches more than 70%. The content of nicotine of the burley tobacco and tomato combination is reduced remarkably, the field growth condition is basically consistent with the cion own-rooted seedling, and the acre yield remains almost the same.

Description

technical field [0001] The invention relates to the technical field of burley tobacco cultivation, in particular to a method for reducing nicotine in burley tobacco. Background technique [0002] Burley tobacco is the main raw material for making blended cigarettes. It has the characteristics of thin and light leaves, loose but not rough tissue structure, strong elasticity, high filling value, and good performance in absorbing flavors. It plays a unique role in cigarette formulations. At present, the nicotine content of domestic burley tobacco leaves is too high, which seriously affects the use of burley tobacco in cigarette formulations, and its usability and resource utilization rate are both reduced. Excessive nicotine content is also the most important factor affecting its use value. Aiming at the problem of high nicotine content in burley nicotine, there are many domestic researches. The results show that the nicotine in burley nicotine can be reduced to a certain exten...

At present, the nicotine content of domestic burley tobacco leaves is too high, which seriously affects the use of burley tobacco in cigarette formulations, and its usability and resource utilization rate are reduced. Excessive nicotine content is also the most important factor affecting its use value

Aiming at the problem of high nicotine content in burley nicotine, there are many domestic researches. The results show that the nicotine in burley nicotine can be reduced to a certain extent by reducing the nitrogen application rate per mu, but the yield per mu is also reduced accordingly, and the benefit per mu is reduced ; The effect of reducing nicotine in burley tobacco by increasing the number of remaining leaves is not significant, and it is easy to reduce the internal quality of burley tobacco leaves, especially the quality of smoking evaluation.

Therefore, it is difficult to solve the problem of excessive nicotine in burley nicotine by reducing the amount of nitrogen per mu and increasing the number of leaves left.
