Method for cultivating cigar wrapper tobacco leaves

Abstract

The invention discloses a method for cultivating cigar wrapper tobacco leaves, comprising the following steps: selecting a first crop field; adjusting the pH value of the soil to 5.5-6.5; making ridges, applying base fertilizer, and disinfecting; mixing the seeds with fine sand after the seeds are disinfected, soaked and accelerated germination; evenly sowing the seeds on the surfaces of seedbeds; laying sunshade nets on the seedbeds; keeping the water-holding capacity of the seedbeds according to different growth periods; preparing the tobacco field before transplanting the tobacco seedlings; applying the base fertilizer through deeply ploughing the tobacco field; ditching planting ditches and transplanting; laying the sunshade nets; keeping the water-holding capacity of the tobacco field according to the different growth periods; pruning top when the tobacco seedlings grow until the rachides grow out; harvesting the tobacco leaves one by one according to the parts from bottom to top after the tobacco leaves grow proper mature, so as to obtain high-quality tobacco leaves. By adopting an overshadow planting technique, the method of the invention can plant out the tobacco leaves with open and flat leaf surface, moderate thickness, thin leaf veins, low damage degree and darker color; the tobacco leaves conform to the requirement of top-grade cigar wrapper tobacco leaves, thus the method has positive significance in the cigar industry development of China.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, in particular to a method for cultivating cigar wrapping tobacco leaves. Background technique [0002] Cigars are a special kind of cigarette product, which has the characteristics of strong strength, mellow and full aroma, bitter and sweet taste, less tar and nicotine, and less harmful to human body than ordinary cigarettes.

Cigars are divided into wrappers (outer skin tobacco leaves), binders (inner skin tobacco leaves) and fillers (core leaves) according to their uses. Among them, cigar outer skin tobacco leaves are required to be moderate in size, wide in shape, thin in leaf shape, smooth in texture and lustrous in color. Uniform; flat veins, fine tissue, good elasticity, even and complete combustion, without affecting the taste of core ciga...

Problems solved by technology

The cultivation of cigar tobacco leaves is mainly concentrated in the Yangtze River Basin and the areas south of it, such as Hainan, Sichuan, Zhejiang, Guangdong, Jiangxi, Guangxi, Yunnan, and Guizhou, which meet the demand for cigar tobacco in the domestic market to a certain extent. The primitive and backward technology has led to low yield and low quality of cigar raw materials in my country, especially cigar wrapping tobacco leaves. The wrapping tobacco leaves used in the production of high-end cigars have to be imported from abroad, which seriously restricts the development of my country's cigar tobacco industry.

After searching, it is found that there is no relevant literature on the cultivation technology of cigar wrappers
