Embodiment 1

[0016] A method for reducing the hazards of "high temperature forced ripening" of flue-cured tobacco, including spraying light damage prevention and control agents, strengthening secondary metabolism of tobacco plants during the maturation stage, and coordinated control of the three factors of light, temperature, and humidity in the late stage of flue-cured tobacco maturation;

[0017] The photodamage prevention and control agent is 20mmol L -1 CaCl 2 ;The method of use is: normal cultivation and management conditions + light damage prevention and control, light damage control is sprayed on the leaves in the early stage of maturity;

[0018] The method for strengthening the secondary metabolism in the mature stage of the tobacco plant is to spray a secondary metabolism inducer in the mature stage of the tobacco strain: the secondary metabolism inducer is 100 mg·L -1 Salicylic acid; applied by spraying method; foliage sprayed twice at maturity and 10 days before harvest;

Abstract

The invention discloses a method for reducing the harm of high-temperature ripening to flue-cured tobacco. The method for reducing the harm of high-temperature ripening to the flue-cured tobacco comprises the steps of: spraying a light-damage preventing and controlling agent, strengthening secondary metabolism of tobacco plants in a mature stage and controlling three factors of light, temperatureand humidity in a late mature stage of the flue-cured tobacco in a coordinated mode. By spraying the light-damage preventing and controlling agent and a secondary metabolite inducer to the flue-curedtobacco in an area which suffers from the harm of high-temperature ripening and controlling the three factors of light, temperature and humidity in the late mature stage of the flue-cured tobacco in acoordinated mode on the area, the harm of high temperature ripening to the flue-cured tobacco can be reduced, higher yield and quality can be obtained, and better economic benefits can be achieved.

Description

technical field [0001] The invention relates to a metabolic regulation mechanism of flue-cured tobacco, in particular to a method for reducing the harm of "high temperature forced ripening" of flue-cured tobacco. Background technique [0002] Tobacco is a plant that is very sensitive to changes in environmental conditions. Ecological factors have a greater impact on the yield, quality and safety of tobacco leaves. Although varieties and cultivation techniques are important factors that affect the quality of tobacco leaves, ecological factors are the quality of tobacco leaves. The basic conditions for the formation of characteristics and styles of regional characteristics. [0003] In the southern Jiangxi tobacco area, there are prone to meteorological disasters such as high temperature and strong light radiation that are unfavorable to the growth of flue-cured tobacco, resulting in the phenomenon of "high temperature forced ripening". In recent years, due to the research on...
