Problems solved by technology

[0005] However, the method of configuring chemical source harm reducers to reduce NNK in tobacco leaves in the rebaking process of tobacco leaves adds additional and cumbersome chemical reagent deployment work, increases cost and workload, and also brings control of reagent content accuracy and Operational uniformity and other issues; and the addition of a heating and dehumidification circulation system during the modulation process also brings additional cost increases, which is not conducive to large-scale promotion

Embodiment 1

[0025] The method for reducing TSNAs of sun-cured tobacco leaves based on organic fertilizer in this embodiment includes the following steps:

[0026] Step (1), planting sun-cured tobacco

[0027] Sun-cured tobacco was grown in the Nongzhang Sun-cured Tobacco Base in Yingjiang County, Yingjiang Prefecture, Yunnan Province. The row spacing is 100 cm×50 cm, and there are 1333 plants per mu.

[0028] Step (2), apply organic fertilizer

[0029] Fertilize the sun-cured tobacco in step (1). The organic fertilizer N:K:P=6:3:6, organic matter 52%, pH=6.9, the source is Yunnan Sichuangge Technology Co., Ltd.

[0030] Specific application method: 80% of the total amount of organic fertilizer 2000 kg / hm2 is used as the base fertilizer before the transplanting of sun-cured tobacco, 10% of the total amount of organic fertilizer is mixed with water 8 days after transplanting, and 20 days after transplanting 10% of the total organic fertilizer is mixed with water and applied. Spray conventional fo...

Embodiment 2

[0036] In the method for reducing TSNAs of sun-cured tobacco leaves based on organic fertilizer in this embodiment, in step (2), during the planting process, tobacco organic fertilizer is applied according to the growth requirement of sun-cured tobacco, and the N:K:P=5 of the organic fertilizer: 4: 5; Among them, 78% of the total organic fertilizer 2200kg / hm2 is used as the base fertilizer before the sun-dried tobacco transplantation, and 10% of the total organic fertilizer is mixed with water 8 days after transplanting, and 20 days after transplanting Mix 12% of the total organic fertilizer with water. Spray conventional foliar potassium fertilizer 1600g / hm in the vigorous and budding periods respectively 2 . The rest is the same as in Example 1.

Embodiment 3

[0038] In the method for reducing TSNAs of sun-cured tobacco leaves based on organic fertilizer in this embodiment, in step (2), in the planting process, tobacco organic fertilizer is applied according to the growth requirement of sun-cured tobacco. The N:K:P=7 of the organic fertilizer: 4: 7; Among them, 82% of the total organic fertilizer 2100kg / hm2 is used as the base fertilizer to be applied in the hole before the transplanting of the sun-cured tobacco. 8 days after the transplanting, 9% of the total organic fertilizer is mixed with water, and 20 days after the transplanting Mix 9% of the total amount of organic fertilizer with water. Spray conventional foliar potassium fertilizer 1600g / hm in the vigorous and budding periods respectively 2 . The rest is the same as in Example 1.

[0039] As a control, the organic fertilizer in Example 1 was replaced with a special compound fertilizer for tobacco, and the application of organic fertilizer was carried out at the same time as t...

Abstract

The invention relates to a method for lowering sun-cured tobacco leaf TSNAs based on organic fertilizer. The method comprises the steps of planting sun-cured tobacco, applying organic fertilizer, sampling and measuring. Only organic fertilizer needs to be applied in the sun-cured tobacco planting process for replacing composite fertilizer special for tobacco, the modulated sun-cured tobacco leaf TSNAs content can be greatly lowered to reach 78% or above, the safety of the sun-cured tobacco leaf formula is improved, and the popularization value is obtained.

Description

Technical field [0001] The invention relates to a method for reducing TSNAs of sun-cured tobacco leaves, in particular to a method for reducing TSNAs of sun-cured tobacco leaves based on organic fertilizer, and belongs to the field of tobacco analysis. Background technique [0002] In addition to flue-cured tobacco leaves, sun-cured tobacco leaves are also used in moderate amounts in the production of Chinese cigarettes. Sun-cured tobacco has significantly higher TSNAs than flue-cured tobacco, so it often faces the problem of how to reduce TSNAs in use. [0003] TSNAs (tobacco-specific nitrosamines) are a class of harmful ingredients. At present, more than 300 N-nitrosamines have been found to be carcinogenic to more than 40 animals in the world, but tobacco products and smoke are mainly known to be 4 types: N-nitrosonornicotine (NNN), 4-(N-methyl-nitrosamine)-1-(3-pyridyl)-1-butanone (NNK), N- Nitro-Nicotinoid (NAT) and N-nitrosopseusoidine (NAB), among which NNN, NNK and NAT ar...
