Promoting agent for promoting tobacco mature yellowing and promoting method thereof

Abstract

The invention relates to a promoting agent for promoting tobacco mature yellowing and a promoting method thereof. The promoting agent comprises the following ingredients in percentage by weight: 0.05 to 0.25 percent of glufosinate, 0.5 to 1.5 percent of potassium bicarbonate and the balance water. The promoting method comprises the following steps that in the tobacco mature period of 7 to 10 days before the tobacco harvesting, the promoting agent is sprayed onto leaves of tobacco leaves until the surfaces of the tobacco leaves are wet. In the mature period of the tobacco, the promoting agent capable of accelerating the tobacco mature yellowing is sprayed onto the leaves of tobacco plants, and the activity of nitratases and GS enzymes in the nitrogen element metabolic process is inhibited through the promoting agents, so that the nitrogen element anabolism is decelerated, the catabolism is accelerated, and the degradation of pigment in the tobacco leaves and the macromolecular substances in the tobacco leaves is accelerated, so that the tobacco leaves naturally realize mature yellowing, and meanwhile, the mature degree of the tobacco leaves is also ensured after the sufficient degradation of pigment and macromolecular substances.

Description

Technical field: [0001] The invention belongs to the technical field of tobacco growth promotion, and in particular relates to an accelerator for promoting the ripening and yellowing of tobacco leaves in the mature stage of tobacco production and a promotion method thereof. Background technique: [0002] In the process of tobacco leaf curing, the maturity of tobacco leaves plays an important role. Tobacco leaves with better maturity and yellowing are easy to bake and produce high-quality tobacco leaves to meet industrial needs. Tobacco leaves with insufficient maturity are easy to bake There are more macromolecular substances such as pigments in the tobacco leaves, which seriously affect the appearance, sensory quality and intrinsic quality of the tobacco leaves. At present, the tobacco planting soil in some areas of China has relatively strong soil viscosity, and the supply of nitrogen elements required for tobacco growth lags behind, resulting in low temperature during t...

AI Technical Summary

Problems solved by technology

At present, in terms of tobacco leaf curing, there is still no effective way to treat tobacco leaves with poor maturity and poor yellowing. We can only find ways to improve the maturity and yellowing of tobacco leaves as much as possible from the aspect of tobacco planting.
