Problems solved by technology

It not only supplements the nutrient elements for tobacco but also avoids the disadvantages of using chemical fertilizers, such as easy to pollute the environment, make the soil harden, destroy the soil quality of the tobacco field, deplete the organic matter in the soil, and reduce the soil fertility, etc.
Moreover, there is no report on the application of Bacillus suffolus with high-efficiency phosphorus-solubilizing and IAA-producing functions and its application in promoting tobacco growth.

Abstract

The invention discloses bacillus safensis and an application thereof. The strain is classified and named as bacillus safensis JX9 and is collected in China General Microbiological Culture Collection Center (CGMCC) in No.3, No.1 Courtyard, Beichen West Road, Chaoyang District, Beijing, with collection date of August 28, 2014 and collection number of CGMCC No.9617. The strain has good phosphate solubilizing effects. Ultraviolet spectrophotometry shows that the strain has the capacity of producing auxin. Research results show that the strain JX9 has potential application value in promoting tobacco growth.

Description

Technical field [0001] The invention belongs to the technical field of plant rhizosphere growth-promoting bacteria and its application, and specifically relates to a Bacillus saffron with the functions of solubilizing phosphorus and producing IAA for promoting tobacco growth and the application of its growth-promoting properties. Background technique [0002] Tobacco is an annual herb of the Nicotiana genus of the Solanaceae family (Solanaceae). It likes temperature, light, drought, fear of flooding, barrenness, and requires more potassium. Tobacco leaves, stems, calyxes and fruits all have multicellular hairs. The glandular hair cells contain chlorophyll, which can comprehensively contain the exudates of gum and resin, which has a certain relationship with the aroma of tobacco. Tobacco petioles are inconspicuous or wing-like stalks, and its panicles are terminal, the calyx is tubular, the corolla is funnel-shaped, and the end is pink. Capsules, yellow-brown seeds. Tobacco is ...
