Problems solved by technology
Although the increase of nitrogen compounds absorbed by tobacco leaves will be beneficial to the synthesis of nicotine, it will also increase the content of other types of nitrogen-containing heterocyclic compounds, and some of these heterocyclic compounds will have side effects on tobacco quality, such as 2 -Formylpyrrole can make the smoke taste harsh

Embodiment 1
[0040] Test site: Xiguanzhuang Village and Dongzhou Village, Feixian County, Linyi City.
[0041] The variety of flue-cured tobacco tested: NC55.
[0042] Tobacco planting soil: select medium-fertile plots, nitrogen application rate is 5.0KgN / mu (local conventional nitrogen application rate), and the fertilizer used in the test is tobacco special fertilizer (Sun Island Compound Fertilizer; Shandong Longfu Fertilizer Co., Ltd.).
[0043] Field management requirements:
[0044] 1) Seedling raising: use greenhouse floating seedlings to cultivate disease-free 55-day-old strong seedlings.
[0045] 2) Transplanting density: the plant spacing is 50cm×120cm.
[0046] 3) Fertilization: The base fertilizer adopts the method of "strip application", which accounts for 60% of the total fertilizer consumption; the topdressing adopts the fixed-point quantitative topdressing method, and the fertilization points are located at the corresponding positions of the leaf tips on both sides of the...
Embodiment 2
[0056] (1) Tobacco leaf production:
[0057] Location: Xiguanzhuang Village and Dongzhou Village, Fei County, Linyi City.
[0059] Field test design: the nitrogen application rate is 5.0KgN / mu (local conventional nitrogen application rate), and the fertilizer used in the test is a special fertilizer for tobacco (Sun Island Compound Fertilizer; Shandong Longfu Fertilizer Co., Ltd.). Choose medium-fertile plots, and plant 400 flue-cured tobacco plants for each variety. Each test variety was listed and roasted at each test site.
[0060] Experimental field management requirements:
[0061] ①Raising seedlings: use greenhouse floating seedlings to cultivate disease-free and healthy seedlings of the right age.
[0062] ②Transplanting density: the plant spacing is 50cm×120cm.
[0063] ③Fertilization: The base fertilizer adopts the method of "strip application", which accounts for 60% ...

Abstract
The invention provides a planting method capable of increasing nicotine content in cut tobacco and the quality of the cut tobacco and belongs to the technical field of cut tobacco production. The method includes the steps of firstly, removing 2-3 tobacco leaves near the ground 30-45 days after flue-cured tobacco transplanting; secondly, removing tobacco leaves away from the ground and growth points to keep 17-18 tobacco leaves 3-8 days after the removing of the tobacco leaves close to the ground to obtain flue-cured tobacco seedlings after topping; thirdly, when the top tobacco leaves of the flue-cured tobacco seedlings after topping are parallel to the top, removing imperfect tobacco leaves to keep 13-14 tobacco leaves to obtain finely trimmed flue-cured tobacco seedlings; fourthly, harvesting the tobacco leaves 20-30 days after the maturity of the finely trimmed flue-cured tobacco seedlings. By the method, the nicotine content in cut tobacco can be increased while the high-quality taste of the cut tobacco can be guaranteed, the contradiction between 'high nicotine content' and 'high quality' is solved, and both 'high nicotine content' and 'high quality' can be achieved.
Description
technical field [0001] The invention belongs to the technical field of tobacco production, and in particular relates to a method for improving the nicotine content in tobacco leaves and the quality of tobacco leaves. Background technique [0002] The physiological strength of tobacco leaves refers to the physiological stimulation of the human nervous system by the smoke produced by the burning of tobacco leaves, also known as strength. Physiological strength is mainly due to nicotine. The higher the nicotine content of tobacco leaves, the greater the physiological strength; on the contrary, the lower the physiological strength, that is, the less vigor. Nicotine is an important index to evaluate the quality of tobacco. The nicotine content is low, the taste is flat; the nicotine content is high, the strength is strong, the total nitrogen content is high, the taste is bitter, and the smoke taste is rough. [0003] At present, the method of applying high-nitrogen fertilizers...
