Tobacco planting method preventing heat-forced maturity

Abstract

The invention belongs to the technical field of tobacco planting, and discloses a tobacco planting method preventing heat-forced maturity. The method comprises the steps that in the tobacco growing period, the environment temperature is measured, and when the environment temperature is greater than 25 DEG C and less than or equal to 35 DEG C, a secondary metabolism inducer is sprayed; when the environment temperature is greater than 35 DEG C, a light damage control agent and the secondary metabolism inducer are sprayed, wherein the light damage control agent is a 10-20 mmol / L CaCl2 aqueous solution, each liter of the sprayed secondary metabolism inducer is prepared by mixing 0.5-1 mg by mass of 24-epicastasterone, 100-200 mg by mass of salicylic acid, 10 mg by mass of methionine, 1 mg by mass of cortex periplocae polysaccharide and 1 mg by mass of sodium phosphate, and the solvent is water. After tobaccos are planted through the method, the heat injury phenomenon of tobacco leaves is obviously weakened, the plant morbidity is obviously lowered, and the heat-forced maturity phenomenon in the tobacco planting process can be effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of tobacco planting, and in particular relates to a tobacco planting method for preventing high-temperature forced ripening. 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 affecting 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. In many places in my country, there are prone to meteorological disasters such as high temperature and strong light radiation that are unfavorable to the growth of flue-cured tobacco. Taking Fuzhou as an example, the climate characteristics belong to the medium-light high-temperature zone. The total sunshine hours during the gro...

Problems solved by technology

In many places in my country, there are prone to meteorological disasters such as high temperature and strong light radiation that are unfavorable to the growth of flue-cured tobacco. Taking Fuzhou as an example, the climate characteristics belong to the medium-light high-temperature zone. The total sunshine hours during the growth period are 700h and the cloudy days are 90d. The high temperature weather of 35°C usually occurs for more than 40 days. However, the temperature during the growth period of flue-cured tobacco is higher than 30°C, especially at 35°C, the consumption of dry matter is greater than the accumulation. , even a short-term high temperature will destroy chlorophyll and affect photosynthesis, which will lead to the phenomenon of "high temperature forced ripening" of tobacco and affect the quality of tobacco leaves

[0003] In recent years, due to the fact that the research on tobacco cultivation technology lags behind the rapid development of tobacco leaf production, as well as the inconsistency of ecological factors, tobacco planting and production frequently occur that the tobacco leaves cannot be normally yellowed at the mature stage, and the tobacco leaves are bleached and brown spots are serious, which affects the quality of the tobacco leaves. quality and availability

Therefore, the influence of temperature on the quality of flue-cured tobacco has attracted more and more attention from researchers in the tobacco industry. However, due to the lack of sufficient attention in understanding the phenomenon of high-temperature ripening of tobacco for a long time, it is extremely lacking in theoretical research.
