Embodiment 1

[0023] Embodiment 1: No. 1 microbial fermentation production of salt solution

[0024] First activate the No. 1 bacterial strain of Jieyan, and then rinse the slope with 5ml of sterile water to form a bacterial suspension. The bacterial suspension is placed in a 500ml triangular flask containing 100ml of No. 1 liquid medium and cultured on a shaker for 24 hours, the culture condition is 28°C, 180-200rpm, the concentration of bacteria is detected, and when the concentration reaches 10 8 Order of magnitude; the bacterial liquid in the 500ml Erlenmeyer flask is transferred to a 500L fermenter containing 250L No. 2 medium according to the inoculum amount of 5%, the insertion amount is 12.5L, and the fermentation conditions are: temperature 28-30°C, Air flow 18m 3 / h, the rotating speed is 0-6h 200rpm, 6-8h 300rpm, 8h to the end of fermentation 400rpm, cultivate for 26 hours, detect the concentration of bacteria, when the concentration reaches 10 8 Order of magnitude; the bacteri...

Embodiment 2

[0025] Embodiment 2: the preparation of microbial fertilizer

[0026]The microbial strain agent that embodiment 1 is made is further processed into microbial fertilizer according to the prescription provided by the present invention. Specifically, in the final microbial fertilizer, fulvic acid 110g / L, potassium dihydrogen phosphate 12g / L, phosphoric acid 20g / L, zinc sulfate 40g / L, ferrous sulfate 95g / L, ammonium molybdate 2g / L , copper sulfate 10g / L, manganese sulfate 5g / L, borax 90g / L, microbial strain agent 100g / L

Embodiment 3

[0027] The preparation of embodiment 3 microbial fertilizer

[0028] The microbial strain agent that embodiment 1 is made is further processed into microbial fertilizer according to the prescription provided by the present invention. Specifically, in the microbial fertilizer finally made, microbial strain agent 50g / L, fulvic acid 30g / L, potassium dihydrogen phosphate 10g / L, phosphoric acid 15g / L, zinc sulfate 37g / L, ferrous sulfate 81g / L L, copper sulfate 8g / L, manganese sulfate 3g / L, borax 83g / L.

Abstract

The invention relates to a bacterial strain, a microbial fertilizer containing the bacterial strain, and a preparation method and a use of the microbial fertilizer. The microbial fertilizer is prepared by reasonable combination and blending of a bacillus atrophaeus strain agent, fulvic acid, monopotassium phosphate, phosphoric acid, zinc sulfate, ferrous sulfate, ammonium molybdate, copper sulfate and manganese sulfate as raw materials. The microbial fertilizer can improve salinity soil, has effects of salt decomposition and growth promotion of a plant, and adjustment of a structure and a pH value of soil, also has high fertilizer efficiency and a long quality guarantee period, and solves the problems of saline-alkali soil harm, a short quality guarantee period and poor fertilizer efficiency.

Description

technical field [0001] The technical solution of the present invention belongs to the field of agricultural fertilizers, specifically, it is a soil improver belonging to the field of microbial fertilizers in the field of biological fertilizers. Background technique [0002] The unreasonable use of chemical fertilizers for a long time has brought about problems such as soil compaction, salinization, fertility decline, ecological damage, and decline in the quality of agricultural and sideline products, and has been highly valued by relevant state departments and agricultural science and technology circles. Our country has been seeking to overcome the disadvantages of soil compaction, salinization, soil fertility decline and agricultural production cost increase caused by extensive use of chemical fertilizers. [0003] Agricultural fertilizers include chemical fertilizers and microbial fertilizers. And microbial fertilizer (a kind of biological fertilizer) as a kind of importa...
