Embodiment 1

[0025] A siderophore-producing Paenibacillus, the strain is classified as Paenibacillus illinoisensis, preserved by: General Microorganism Center (CGMCC), China Committee for Culture Collection of Microorganisms, address: 1 Beichen West Road, Chaoyang District, Beijing No. 3 Courtyard, date of deposit: August 29, 2014, deposit number: CGMCC No.9620.

[0026] CGMCC9620 screening process:

[0027] (1) Separation and purification

[0028] The strain was isolated and screened from peanut rhizosphere soil.

[0029] Soil samples were collected from a peanut planting site in Zhaiziwa (35°44'N, 116°75'E), Yanzhou City, Shandong Province. Carefully shake off the peanut rhizosphere soil into a sterile bag, put it in a low-temperature fresh-keeping box, and process it immediately after bringing it back to the laboratory. Weigh 10 g of the rhizosphere soil sample, put it into 90 mL of sterile water, and shake it for 30 min to make a soil suspension. Take 1mL of the suspension respecti...

Abstract

The invention discloses a siderophore-producing Paenibacillus, the strain is Paenibacillus illinoisensis, which was preserved in the General Microorganism Center (CGMCC) of China Microbiological Culture Collection Management Committee (CGMCC) on August 29, 2014, address: Beijing No. 3, Courtyard No. 1, Beichen West Road, Chaoyang District, City, preservation number: CGMCC No.9620. The strain of the present invention can produce siderophores in iron-limited medium. Under potted and field conditions, using the bacterial suspension of the siderophore strain of the present invention to soak peanuts before sowing and root irrigation during the growth period can significantly improve the iron nutrition of peanuts in the growth period in calcareous soil, and can Increase the chlorophyll content of peanuts, enhance the root activity of peanuts, promote the accumulation of nitrogen, phosphorus, and potassium in peanut plants, increase plant biomass, improve peanut quality, and increase peanut yield.

Description

technical field [0001] The invention relates to a siderophore Paenibacillus and application thereof. Background technique [0002] Peanut is an important oil crop and economic crop in China, and northern China is one of the largest peanut cultivation areas. In recent years, the occurrence of iron-deficiency chlorosis in peanuts has become more and more serious, which has caused great damage to the yield and quality of peanuts. At present, people mainly rely on agricultural control and chemical control methods to prevent and control peanut iron deficiency yellowing disease, but agricultural control methods are time-consuming and laborious, and it is difficult to effectively prevent the occurrence of diseases from the root cause. Human health also has certain harm. Therefore, the use of biological methods to prevent and control the occurrence of peanut iron-deficiency yellowing has gradually become a hot spot of concern, and the key is to find strain resources that have a go...
