Abstract

The invention relates to composite selenium fertilizer for tobacco leaf surface spraying and an application in selenium-enriched tobacco leaf production. Th composite selenium fertilizer comprises thefollowing components, by weight: 7-13 parts of sodium selenite, 10-15 parts of a surfactant, 7-13 parts of diethyl aminoethyl hexanoate, and 240-260 parts of fulvic acid. Compared with direct spraying of a sodium selenite solution, the composite selenium fertilizer for tobacco leaf surface spraying can effectively improve the economic properties of tobacco to significantly increase the proportionof superior tobacco, can maximize the improvement of physical properties of the tobacco to increase the usability, can increase the potassium content of the tobacco to make the chemical composition more coordinated, can increase the content of neophytadiene to increase the concentration of aroma and improve the quality of aroma, and can significantly reduce the content of malondialdehyde and increase the activity of glutathion peroxidase to effectively improve the antioxidant capacity of the tobacco. Compared with conventional selenium fertilizer, the composite selenium fertilizer is improvedin the improvement of the growth of the tobacco and the quality of the tobacco, and can be effectively applied to a production process of selenium-enriched tobacco leaves.

Description

technical field [0001] The invention belongs to the field of selenium fertilizer for tobacco, and in particular relates to a compound selenium fertilizer for tobacco leaf surface spraying and its application in the production of selenium-enriched tobacco leaves. Background technique [0002] Selenium has been identified as one of the essential nutrients for humans and animals, and plays an important role in preventing diseases, fighting cancer, alleviating and improving human immunity. Whether selenium is an essential nutrient element for plant growth has not yet been definitively determined, but selenium is a beneficial trace element for plant growth. Plants can absorb, utilize, and transform selenium in the environment to varying degrees, and convert different forms of selenium into Organic selenium such as selenoproteins. Due to the high toxicity of inorganic selenium, a small dose will cause damage to the human body. The plant-human food chain is a safe and effective wa...
