Embodiment 1

[0030] One, cultivation method of the present invention

[0031] Test site: Biji Village, Lawu Township, Binchuan County, Dali Prefecture, Yunnan Province.

[0032] Test materials and methods:

[0033] The flue-cured tobacco variety is NC297, and the planting density is 16,500 plants / ha.

[0034] Fertilizer: Rapeseed cake fertilizer and potassium magnesium sulfate fertilizer. The potassium magnesium sulfate fertilizer is a fertilizer containing moderate elements such as magnesium and sulfur, which is made by physical extraction or direct removal of impurities from salt lake brine or solid potassium magnesium salt mine , which is a fertilizer that meets the national standard GB / T20937-2007 of the People's Republic of China "Potassium Magnesium Sulfate Fertilizer". Qualified grades of "Potassium Magnesium Sulfate Fertilizer", among which potassium oxide (K 2 O) has a mass fraction of 22%. Described potassium magnesium sulfate fertilizer and cake fertilizer, rapeseed cake fer...

[0086] Example 2 Cigarette Hazard Evaluation and Tar Detection of Industrial Verified Cigarettes

[0087]Taking Hongtashan 1956 as a control and the tobacco leaves of Example 1 as raw materials, the cigarettes for industrial verification were processed and rolled according to the formula of Hongtashan 1956. The tar, carbon monoxide, phenol, crotonaldehyde, HCN, and benzene in the smoke of the two cigarettes were analyzed and detected respectively. And [a] pyrene, nitrosamines, ammonia, a total of 8 items. The detection and analysis methods are carried out in accordance with national standards or industry standards: GB / T19609-2004 (Determination of total particulate matter and tar by smoking machine for routine analysis of cigarettes) Determination of tar content, YC / T 30-1996 (Carbon monoxide in cigarette smoke gas phase Determination of non-scattering infrared method) Determination of carbon monoxide content, GB / T 21130-2007 (Determination method of benzo[a]pyrene in total pa...

Abstract

The invention discloses a tobacco cultivation method for reducing the harmfulness of cigarettes, and belongs to the technical field of crop cultivation. The method comprises the following steps: applying a cake fertilizer and a potash magnesium sulphate fertilizer in the cultivation process, namely during soil preparation and ridging and after tobacco is transplanted and survives until a rosette stage, wherein the potash magnesium sulphate fertilizer is a fertilizer containing magnesium and sulfur secondary elements, which is prepared by extracting or directly removing impurities from salt lake brine or solid potassium-magnesium salt ore through a physical method only, the total using amount of the cake fertilizer is 60-90kg/hectare based on the mass of N, and the total using amount of the potash magnesium sulphate fertilizer is 150-225kg/hectare based on the mass of K2O; after a film is uncovered, applying the cake fertilizer by combining cultivation and banking; and spraying the potash magnesium sulphate fertilizer after bottom leaves are removed, and performing pest control. The tar content in the cigarettes made of tobacco produced by the method can be reduced by 16.9 percent, the cigarette harmfulness evaluation number is reduced by 21 percent, and the quality of flue-cured tobacco reaches indexes of high-quality tobacco.

Description

technical field [0001] The invention belongs to the technical field of crop cultivation, and in particular relates to a tobacco cultivation method for reducing the harmfulness of cigarettes. Background technique [0002] Tobacco is an important economic crop in China. Despite the surging anti-smoking campaign, the global demand and sales of tobacco products still maintain a steady and slight increase. When smoking and health issues are generally concerned by the whole society, the quality and safety of cigarette raw materials and the hazards of cigarettes are also increasingly valued. The quality and safety of tobacco leaves mainly refers to the public health problems that the toxic and harmful substances in tobacco leaves affect human health. The toxic and harmful substances include two aspects: endogenous and exogenous. Endogenous harmful substances such as tar, carbon monoxide (produced by burning tobacco leaves and inhaled by people), phenol, crotonaldehyde, nitrosamine...
