Special marine biological fertilizer for tobacco as well as preparation method and application of fertilizer

Abstract

The invention provides a special marine biological fertilizer for tobacco as well as a preparation method and an application of the fertilizer. The special marine biological fertilizer for the tobacco is prepared from enteromorpha polysaccharides having an obvious promoting effect on the appearance and the inherent quality of the tobacco, and exopolysaccharides generated by a screened bacillus vallismortis SJ strain resistant to viral and fungal diseases, wherein the bacillus vallismortis SJ strain is collected in China General Microbiological Culture Collection Center with the collection number of CGMCC No.7571. The special marine biological fertilizer is capable of reducing the content of heavy metals in the tobacco leaves, increasing the total sugar and reducing sugar content of the tobacco leaves and enhancing the disease resisting and growth promoting ability of the tobacco. The marine biological fertilizer is applied to the tobacco and capable of achieving the purposes of environmental protection, high efficiency and new type; and besides, the marine biological fertilizer is capable of obviously improving the tobacco leaf quality, contributes for increasing the income of peasants and the local finance and taxation, and has a favorable market application prospect.

Description

technical field

[0001] The invention belongs to the field of biotechnology, and in particular relates to a special marine biological fertilizer for tobacco and its preparation method and application. Background technique

[0002] Seaweed polysaccharide is the main active substance in seaweed, which can enhance crop resistance, enhance the osmotic pressure of cells by regulating cell osmosis, thereby enhancing the ability of cold resistance, drought resistance, and salt-alkali resistance; it can participate in the body's photosynthesis and indirectly improve the body's immunity It can prevent and control viral and fungal diseases, and has an anti-absorption effect on heavy metals and other toxic substances, effectively improving crop quality. As an additive, seaweed polysaccharide can enhance the stability and solubilization of the product, enhance the emulsification, water absorption and chelation of inorganic ions and heavy metals in the system. Polysaccharides are importa...
