Problems solved by technology

However, the effect of technical measures is not significant, and the chlorine content of tobacco leaves in some smoking areas is still significantly higher than 8g / kg, and some even exceed 20g / kg
Chinese patent (application number 201410266722.1) discloses a crop rotation and no-tillage method for reducing the chloride ion content of tobacco leaves in field tobacco planting areas. planting) and no-tillage direct seeding, no-tillage intercropping to reduce the chlorine content of tobacco leaves in Yunnan tobacco areas. This technology is aimed at a technical measure of excessive chloride ion and tobacco leaf chlorine content in the soil of the Yunnan tobacco area under water-drain rotation. Obviously, it does not It is suitable for dry-farming tobacco fields in the Huang-Huai-Hai area, and the technology has many links, complicated procedures, and a long implementation period
Some scholars have analyzed the sources of chlorine absorption in tobacco leaves, and found that the chlorine content of tobacco leaves can be effectively reduced through the control of irrigation water, but irrigation as irrigated agricultural groundwater is indispensable. It can be seen that it is difficult to achieve a good chlorine reduction effect with a single technology
[0005] To sum up, excessive chlorine content in tobacco leaves is still an important problem in the production of high-quality tobacco leaves in the Huanghuai-Hai tobacco-growing region, and there is currently a lack of appropriate effective technical measures to reduce the chlorine content of tobacco leaves. Excessive chlorine content severely limits the quality of tobacco leaf raw materials in the Huanghuai-Hai tobacco region. and market competitiveness

Embodiment 1

[0023] In 2015, a tobacco field was selected in Shuanggou Town, Bozhou City, Anhui Province, which is located in the Huanghuaihai Tobacco Area. The tested flue-cured tobacco variety was Longjiang 911. The soil was collected to measure the chloride ion content before the flue-cured tobacco was planted. Tobacco leaves were measured for yield and value, and the tobacco leaves were collected to measure chlorine content and potassium content, and sensory quality evaluation was carried out. The example sets two processes:

[0024] Control treatment: conventional ridging, fertilization, transplanting, irrigation, normal harvesting and roasting, namely:

[0025] In March 2015, the flue-cured tobacco field was selected for planting, and the water-soluble chloride ion content of the plow layer soil before tobacco planting was 26.5mg / kg.

[0026] On April 13, 2015, soil preparation, ridging, and fertilization were carried out. After the test field was leveled, fertilization was carried ...

Embodiment 2

[0040] In 2015, a tobacco field was selected in Zhangji Town, Bozhou City, Anhui Province, which is located in the Huanghuaihai Tobacco Area. The flue-cured tobacco variety in the experiment was China Tobacco 100. The soil was collected to measure the chloride ion content before the flue-cured tobacco was planted. Yield and value were measured, tobacco leaves were collected to measure chlorine content and potassium content, and sensory quality evaluation was carried out. The example sets two processes:

[0041] Control treatment: conventional ridging, fertilization, transplanting, irrigation, normal harvesting and roasting, namely:

[0042] In March 2015, the flue-cured tobacco field was selected to be planted, and the water-soluble chloride ion content of the plow layer soil before tobacco planting was 23.6mg / kg.

[0043] On April 10, 2015, soil preparation, ridging, and fertilization were carried out. After the test field was leveled, fertilization was carried out at a dist...

Abstract

The invention aims to solve the problems that in China, tobacco in the Huang-Huai-Hai tobacco-growing area is high in chlorine content, non-coordinating in chemical component, poor in tobacco qualityand the like, and provides a cultivation method capable of reducing the content of chlorine in the tobacco in the Huang-Huai-Hai tobacco-growing area. The cultivation method comprises the steps of tobacco field layout optimization, high ridging and deep cultivation, improvement of the type and the using amount of fertilizers, strict control over application of green manure, staged and deep application of the fertilizers, irrigation way optimization and the like. By means of the method, the absorption sources of the chlorine in the tobacco can be reduced from form the origin, the content of thechlorine in the cured tobacco is obviously reduced by 45% or above, the content of the chlorine is lower than 8 g / kg which conforms to the range of the chlorine content of high-quality tobacco, and potassium content of the tobacco is significantly reduced, the chemical components of the tobacco are more coordinating, the combustibility of crude tobacco is obviously improved, offensive odor is reduced, and the aroma quality and the aroma amount are improved. The production value of the tobacco is increased by 8-10%, the incomings of the tobacco per mu are increased by 250-280 yuan, and the incomings of farmers are significantly increased.

Description

technical field [0001] The invention belongs to the technical field of agriculture, and in particular relates to a cultivation method for reducing the chlorine content of tobacco leaves in the Huanghuaihai Tobacco Region. Background technique [0002] Chlorine is an essential nutrient element for the growth and development of flue-cured tobacco, and it is also an important chemical indicator affecting the quality of tobacco leaves. Flue-cured tobacco is more sensitive to the absorption of chlorine and is known as a "chlorine-avoiding" crop. It is generally believed that the suitable chlorine content of tobacco leaves is 3-8g / kg. When the chlorine content of tobacco leaves is lower than 3g / kg, there will be disadvantages such as poor elasticity, fragility, and low cutting rate of tobacco leaves; however, if the chlorine content of tobacco leaves exceeds 8g / kg, the tobacco leaves will have poor color, poor combustibility, easy flameout, and low industrial usability. Therefo...
