Embodiment Construction

[0035] The related technical problems of the present invention will be further described in detail below. First, the screening of the nitrogen-fixing bacterium strain Achromobacter ZQ305 of the present invention will be described.

[0036] 1. Primary screening

[0037] (1) Medium Mannitol 6-15g, KH 2 PO 4 0.1-0.5g, MgSO 4 ·7H2 O 0.1-0.5g, NaCl 0.1-0.5g, CaSO 4 0.1-0.5g, CaCO 3 3-9.0g, distilled water 900-1200ml, pH6.0-9.0.

[0038] (2) Screening method

[0039] Select flue-cured tobacco rhizosphere soil, use plate dilution separation method, select colony with fast growth and produce brown, brown or black pigment, separate and purify by streaking, transfer to slant for preservation. The strains with high nitrogenase activity were determined by ethylene reduction method for further screening.

Abstract

The invention discloses an efficient azotobacter fertilizer for tobacco and a production method thereof, and belongs to the technical field of azotobacter fertilizer. The azotobacter fertilizer for tobacco comprises an adsorbent and a bacterial suspension containing colorless ZQ305(Achromabacter sp. ZQ305), namely colorless bacillus ZQ305 CGMCC No.3533. The adsorbent is turf, active carbon and vermiculite or is a mixture thereof, and the turf is crushed to 60-80mesh with a water content of 10-20%. In the efficient azotobacter fertilizer, per 400-600g of the adsorbent is added with 100ml of the bacterial suspension. The azotobacter fertilizer can increase soil fertility, flue-cured tobacco output and a proportion of superior tobacco; and the tobacco leaf has good component compatibility and decreased miscellaneous gas and irritant. According to the azotobacter fertilizer, an application amount of nitrogenous fertilizer can be reduced by 10-20% to lower costs; therefore, the efficient azotobacter fertilizer has good social and economic values.

Description

Technical field [0001] The present invention is the field of nitrogen fixation fertilizer technology, which involves a kind of efficient nitrogen fertilizer and its production methods for tobacco. Background technique [0002] Biological nitrogen fixation plays a very important role in the nitrogen cycle of nature and human agricultural production. The amount of biological nitrogen fixing on the earth is about 175 million tons each year.Two -thirds of the nitrogen compounds formed by natural conditions). [0003] The study of biological nitrogen began in the 19th century.In 1838, the French BOUSSINGAULT first confirmed that the clover and peas were the first to obtain nitrogen in the air.Since then, Russia's M.C. Volonen and H. Heirgel in Germany have proven the symbiosis between the beanic plants and the root tumor.In 1885, Berthelot first proved that microorganisms could fix the nitrogen in the air to make the soil fertile.In 1888, Beijerink in the Netherlands first separated t...
