Flue-cured tobacco high-temperature forced mature prevention and control agent and application thereof

Abstract

The invention belongs to the field of tobacco planting, and in particular relates to a flue-cured tobacco high-temperature forced mature prevention and control agent. The prevention and control agent consists of the following components: polyamine, sodium nitroprusside, calcium chloride and monopotassium phosphate. With the application of the flue-cured tobacco high-temperature forced mature prevention and control agent provided by the invention, respiration and transpiration actions of leaves can be fully inhibited, so that accumulation of harmful substances and moisture loss of the leaves can be relieved, and the tobacco leaves can be kept at a relatively high photosynthetic rate; and meanwhile, physiological metabolic activity and stress resistance of tobacco plants in a later period can be enhanced, and coordination of chemical components of the tobacco leaves can be improved. Based upon experimental studies, as field tobacco laves are applied with the prevention and control agent, phenomenons of premature aging, whitening, burns and brownies can be obviously relieved, physiological and quality indexes can be remarkably improved and an obvious using effect can be guaranteed; and the occurrence of a high-temperature forced mature phenomenon in flue-cured tobacco can be effectively prevented and controlled, so that quality of the tobacco leaves can be improved.

Description

technical field [0001] The invention relates to the field of tobacco cultivation, in particular to an agent for preventing and controlling high-temperature ripening of flue-cured tobacco and its application. 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 and quality of tobacco leaves. Among them, climate factors are the main ecological factors that create high-quality and characteristic tobacco leaves. Studies have shown that compared with foreign high-quality tobacco leaf production areas, the meteorological conditions of flue-cured tobacco in my country during the field growth period are mainly manifested in: relatively insufficient sunshine; relatively low temperature in the early stage, and relatively high temperature in the later stage. This phenomenon is particularly prominent in the central and southern smoking areas of my country. [0003] The Nanli...
