Method for improving quality and enhancing aroma of upper leaf of flue-cured tobacco

Abstract

The invention provides a method for improving quality and enhancing aroma of upper leaves of flue-cured tobacco. The method comprises the following steps of: on the basis of conventional ridging fertilization of the flue-cured tobacco, additionally applying 800-1000kg of thoroughly decomposed farmyard manure per mu as base fertilizers; after the middle leaves of the flue-cured tobacco are harvested, evenly applying foliar fertilizers onto the front surfaces and the back surfaces of the upper leaves; and after normal mature harvesting time is delayed for 4-9 days, harvesting the upper leaves in one step and then curing the upper leaves. The foliar fertilizers comprise the following components in percentage by weight: 15-45 percent of borax, 15-45 percent of zinc sulfate, 15-45 percent of manganese sulfate, 3-12 percent of sodium molybdate, 1.5-4.5 percent of copper sulfate and 0-0.001 percent of jasmonic acid. In combination with measures such as additionally applying organic fertilizers in the base fertilizers, applying the foliar fertilizers after the middle leaves are harvested, delaying the harvesting time of the upper leaves and the like, the method for improving quality and enhancing aroma of upper leaves of flue-cured tobacco has the advantages that the method is simple, and the formula use value and the usability of the upper leaves can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of tobacco production, in particular to a method for improving the quality and flavor of the upper leaves of flue-cured tobacco. Background technique [0002] The upper leaves of flue-cured tobacco include 4-6 pieces of upper two shed leaves and top leaves, accounting for about 30% of the output of a single plant, that is, the annual production of about 10 million tons of upper leaves in the country, which occupies a very important position in the production of tobacco leaf raw materials And its irreplaceable role has attracted great attention and attention from relevant technical personnel of tobacco commercial companies and industrial companies. Therefore, how to improve the availability of upper tobacco leaves has become a directional and strategically important research topic for the tobacco industry. In 2009, the Science and Technology Department of the State Tobacco Monopoly Administration specially s...

Problems solved by technology

[0003] Quality problems in the upper leaves of flue-cured tobacco: there are problems such as poor leaf opening in field planting, short and narrow leaves, thick leaves, and difficult to fall yellow. , the suction is too strong and irritating, the miscellaneous gas is heavy, the smoke is rough, and the industrial usability is poor, etc.

[0004] At present, there are many studies on how to improve the quality of the upper tobacco leaves of flue-cured tobacco, most of which focus on maturity standards, harvesting methods, and modulation methods. method” (Application No. 200510038012.4), which focuses on the research of biochemical preparations, but its operation is complicated and labor-intensive, making it difficult to popularize
