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 invention belongs to the technical field of nitrogen-fixing bacterial fertilizer, and in particular relates to a high-efficiency nitrogen-fixing bacterial fertilizer for tobacco and a production method thereof. Background technique [0002] Biological nitrogen fixation plays a very important role in the natural nitrogen cycle and human agricultural production. The annual amount of biological nitrogen fixation on the earth is about 175 million tons, which is equivalent to the available nitrogen sources on the earth (biological nitrogen fixation, chemical nitrogen fixation, lightning and other abiotic 2 / 3 of nitrogen compounds formed under natural conditions). [0003] Research on biological nitrogen fixation began in the 19th century. In 1838, Boussingault of France, through field experiments and chemical analysis, first confirmed that clover and peas could obtain nitrogen from the air. Since then, Russia's M.C. Voronin and Germany's H. Hellriger ...
