Method and system for cultivating Fujian high-quality tobacco with faint sweet and honey sweet fragrance based on transplanting period

Abstract

The invention relates to a method and system for cultivating Fujian high-quality tobacco leaves with faint sweet and honey sweet fragrance based on a transplanting period. Specifically, the inventionprovides a method for determining the transplanting period of Fujian tobacco. The method comprises the steps that historical meteorological data in the past ten years are analyzed, and the historicalday-by-day average temperature of a Fujian tobacco area is calculated; average temperature in the field rooting period, the vigorous growth period and the mature period of tobacco transplanted in every ten days of December, January and February is calculated, and the total accumulated temperature of the tobacco in a field growth period and the active accumulated temperature value of temperatures greater than or equal to 10 DEG C are also calculated; proper transplanting time is selected so as to allow the weather conditions of each growth period of transplanted tobacco to meet the requirementsthat average temperature in the field rooting period is 9-15 DEG C, average temperature in the vigorous growth period is 12-18 DEG C, average temperature in the mature period is 19-22 DEG C, the total accumulated temperature in the field growth period of the tobacco is 2000-2600 DEG C, and the active accumulated temperature value of temperatures more than or equal to 10 DEG C is 1800-2500 DEG C.Tobacco products harvested after transplanting in the transplanting period determined according to the method have improved quality.

Description

technical field [0001] The invention relates to the technical field of tobacco cultivation, in particular to a method and system for cultivating Fujian sweet, sweet, fragrant and high-quality tobacco leaves based on the transplanting period. Background technique [0002] Ecology is a key factor in determining the quality of tobacco leaves. The sowing and planting period is different, and the light conditions, temperature conditions, rainfall and air humidity in the tobacco growth period are also different, so the quality and style of the tobacco leaves produced are also different. Therefore, determining the appropriate transplanting period is an important factor to fully exploit the advantages of local climatic conditions, improve the quality of tobacco leaves, and highlight the style characteristics of tobacco leaves. [0003] The terrain of Fujian is "close to the mountains and the sea", and it belongs to the subtropical marine monsoon climate. The province has abundant r...

Problems solved by technology

High temperature makes respiration greater than photosynthesis and consumes stored nutrients. If the time is too long, the plants will be sunburned or even die, resulting in reduced or even no harvest of tobacco leaves.

At the same time, the high temperature reduces the synthesis of essential coenzymes, interrupts the relevant metabolic activities, produces biochemical damage, reduces the protein synthesis rate, and inactivates the activity of enzymes, resulting in a significant decline in the quality of tobacco leaves.
