Abstract
The invention discloses a high-yield integrated production method for cigar wrappers. This method builds a 'four in one' production facility system that integrates seedling cultivation, transplanting, drying, and fermentation processes of cigar wrapper tobacco leaves. The system has a light intensity of 75-160 μmol/(m·s), a temperature of 25±5° C. and a relative air humidity of 75%±10%; when transplanting tobacco seedlings, using a nutrient solution, which is a high iron boron nutrient solution with an iron content of 0.3-0.7 mM calculated as Fe and a boron content of 9.5-13.0 mg/L calculated as boric acid. The invention achieves a cigar shell yield of over 65%, a 40% reduction in production facility investment, and a 20% reduction in labor force by accurately regulating the production environment and the supply of growth factors such as nutrients and light.
