[0003] At present, the prevention of the fading phenomenon of cured tobacco leaves at home and abroad mainly focuses on the control of the storage environment in the later storage process, such as shading treatment, reducing temperature and humidity, and improving the monitoring of light, temperature and humidity in the storage environment. Although these methods It can prevent the fading of the flue-cured tobacco to a certain extent, but after the flue-cured tobacco is roasted and modulated, it will inevitably be exposed to light during the grading and transportation process. The storage environment during this period is uncontrollable, which leads to the inevitable fading of the flue-cured tobacco. , reducing the industrial availability of flue-cured tobacco and reducing the appearance quality of flue-cured tobacco
In recent years, due to the extensive application of inorganic fertilizers in the production process of tobacco leaves, the soil pH value is low, and the maturity of tobacco leaves is not harvested enough, resulting in a poor growth and development environment for flue-cured tobacco, and the resulting flue-cured tobacco is prone to fading

Abstract

The invention discloses a method for preventing fading of cured tobacco leaves, which belongs to the technical field of tobacco. In the method of the present invention, the application of biochar, dolomite powder, boron fertilizer, magnesium fertilizer, additional application of organic fertilizer, high ridge deep planting and delayed harvesting are all environmentally friendly methods, which will not cause damage to the natural environment. The application of biochar and dolomite powder can effectively improve the soil environment of tobacco planting, ensure the healthy growth of flue-cured tobacco, improve the field agronomic characteristics of flue-cured tobacco, and improve the economic characteristics of flue-cured tobacco. The application of boron fertilizer, magnesium fertilizer and organic fertilizer can effectively increase the pigment content of flue-cured tobacco in the field stage, and delaying harvest can effectively reduce the chlorophyll content of flue-cured tobacco when harvested, improve the ease of curing of flue-cured tobacco, improve the appearance quality of flue-cured tobacco leaves, and effectively improve The fading resistance of flue-cured tobacco. Simultaneously, the raw material source of the invention is convenient, the operation is simple, and it has practical operability for popularization among tobacco farmers.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and relates to a method for preventing fading of cured tobacco leaves during storage. Background technique [0002] Tobacco leaves are the basis for the survival and development of the industry, and the development of Chinese-style cigarettes has continuously increased the requirements for tobacco leaf raw materials. In recent years, the fading phenomenon of cured tobacco leaves has become a prominent problem in my country's tobacco leaf production. It is particularly serious in the southern production areas of my country, especially the southeast tobacco production areas. The appearance shows the phenomenon of "silver gray and whitish", which seriously affects the appearance quality and grade structure of tobacco leaves. [0003] At present, the prevention of the fading phenomenon of cured tobacco leaves at home and abroad mainly focuses on the control of the storage environment in the later sto...
