Problems solved by technology

At present, in order to reduce the supply of nitrate during the growth of tobacco leaves, some tobacco planting areas in my country reduce the accumulation of nitrate in tobacco leaves by adjusting the amount of nitrogen fertilizer or the form of nitrogen, increasing the application of phosphorus fertilizers, and applying hormones. Form negative effects, and the cost is high or the effect is not good, and it is difficult to realize the idea satisfactorily; the breeding cycle of low nitrate accumulation varieties is too long and the effect is slow, so it can only be used as a long-term work
[0005] Tobacco grafting planting is a new method of tobacco planting in recent years, with eggplant ( Solanum melongena L.) as rootstock, tobacco as scion, planting tobacco by grafting, can effectively prevent and control tobacco rhizome diseases. "Method" Chinese invention patent, which can effectively prevent and control tobacco rhizome diseases. However, there is no research on the quality of tobacco and the content of nitrosamines in tobacco by grafting.

Embodiment 1

[0035] A method for reducing the content of nitrosamines in flue-cured tobacco, wherein: comprising the following process steps:

[0036] 1. Planting

[0037] (1) Select rootstock and scion: use Solanum torvum Swartz as the rootstock and tobacco crops as the scion. In this embodiment, Yunyan 87 is used as the scion.

[0038] (2) Seedling cultivation: Sow rootstock seeds and scion seeds to raise seedlings. When the eggplant rootstock seedlings grow to 5-6 true leaves and the tobacco seedlings grow to 5-6 true leaves, take out the eggplant rootstock seedlings and tobacco seedlings and prepare for grafting; Rootstock seeds are sown 25 to 30 days earlier than scion seeds.

[0039] (3) Grafting: Choose a cool or cloudy day, the temperature for grafting is 20°C to 25°C, and the air humidity is above 45% during grafting;

[0040] Cut the eggplant rootstock horizontally at a distance of 9cm to 12cm from the root, remove the upper growth point, and use a blade to split the middle ax...

Abstract

The invention relates to a method for reducing the content of nitrosamine in flue-cured tobacco. Tobacco is planted by grafting with solanum torvum swartz as a rootstock and tobacco as a scion, and the tobacco curing technology is adjusted. Therefore, the goal of reducing the content of nitrosamine in flue-cured tobacco is achieved, the harm of tobacco to human health is reduced, and the quality of tobacco is improved.

Description

Technical field: [0001] The invention belongs to the technical field of improving tobacco quality and reducing tobacco damage to human health, and in particular relates to a method for reducing the content of nitrosamines in flue-cured tobacco. Background technique: [0002] Tobacco-specific nitrosamines (TSNA) mainly include N-nitrosonornicotine (NNN), 4-(N-methyl-nitrosamine)-1-(3-pyridyl)-1-butanone (NNK), N-nitrosoanatabine (NAT) and N-nitroso anatabine (NAB), which have been confirmed to be associated with tumors in the lung, oral cavity, esophagus, pancreas, liver, etc. produce related. [0003] Nitrate is the precursor of tobacco-specific nitrosamines, and its content level is an important indicator of TSNAs accumulation. Nitrate nitrogen is the main form of nitrogen absorbed by plants. It is absorbed and utilized by plants through nitrogen reduction and assimilation. However, when tobacco leaves are stored in the warehouse after harvest, the nitrate nitrogen in tob...
