A method and system for cultivating fujian sweet, sweet and high-quality tobacco leaves based on the transplanting period

Abstract

The invention relates to a method and system for cultivating Fujian Qingtian, sweet, fragrant and high-quality tobacco leaves based on the transplanting period. Specifically, a method for determining the transplanting period of tobacco in Fujian is provided. The method includes: analyzing the historical meteorological data of the past ten years, calculating the historical daily average temperature in the tobacco-growing areas of Fujian; and calculating the field rooting of tobacco transplanted every ten days from December to February period, the average temperature of the flourishing period, and the mature period, and the total accumulated temperature of the tobacco field growth period ≥ 10 ℃; select the appropriate transplanting time, so that the climatic conditions of each growth period of tobacco after transplanting meet the average temperature of the rooting period of the field. The temperature is 9-15°C, the average long-term temperature is 12-18°C, the average temperature in the mature period is 19-22°C, the total accumulated temperature in the tobacco field growth period is 2000-2600°C, and the active accumulated temperature ≥ 10°C is 1800-2500°C. Tobacco products harvested after transplanting according to the transplanting period determined by this 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 of 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 ...

AI Technical Summary

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.
