Problems solved by technology

Since the active conditioner for repairing saline-alkali flat soil contains live bacteria, the drying during the granulation process has a great impact on the number of live bacteria, and because peat and humic acid are mineral organic materials, it is more difficult to dissolve after granulation , grains affect the quality and effect of the product
However, arable land in many places in the north belongs to machine sowing, and powder products cannot be used, so they are not granulated, which directly affects the mass use and promotion of products

Embodiment 1

[0020] A microbial agent for improving saline-alkali land, comprising the following components by weight: 200-250 parts of composite microbial agent, 150-200 parts of peat, 50-100 parts of superphosphate, 50-100 parts of humic acid, EDTA-metal 15-21 parts of chelate, 0.5-1 part of ammonium molybdate, 5-10 parts of borax; it contains live bacillus spores > 0.2 billion / g, compound microbial agents include: Bacillus megaterium, Bacillus jelly-like, Bacillus lateralis, Rhizobium vetense and Paecilomyces lilacinus.

[0021] Each gram of biological fertilizer contains Bacillus megaterium ≥ 1.0×10 8 CFU, Bacillus jelly-like ≥1.5×10 8 CFU, Bacillus lateralis ≥2.5×10 8 cfu, milk vetch Rhizobium ≥1.5×10 8 cfu, Paecilomyces lilacinus ≥1.0×10 8 cfu.

[0022] The preparation method of the microbial bacterial agent improved in the saline-alkali land is characterized in that it comprises the following steps:

[0023] 1) Preparation of bacterial agent polymerization aqueous solution: pr...

Embodiment 2

[0031] A microbial agent for improvement in saline-alkali land, comprising the following components by weight: 200 parts of composite microbial agent, 150-200 parts of peat, 50 parts of superphosphate, 50 parts of humic acid, and 15 parts of EDTA-metal chelate , 0.5 parts of ammonium molybdate, 5 parts of borax; it contains live bacillus spores > 0.2 billion / g, compound microbial agents include: Bacillus megaterium, Bacillus jelly-like, Bacillus lateral sporosum, Rhizobium vetense and Paecilomyces lilacinus.

[0032] Each gram of biological fertilizer contains Bacillus megaterium ≥ 1.0×10 8 CFU, Bacillus jelly-like ≥1.5×10 8 CFU, Bacillus lateralis ≥2.5×10 8 cfu, milk vetch Rhizobium ≥1.5×10 8 cfu, Paecilomyces lilacinus ≥1.0×10 8 cfu.

[0033] The preparation method of the microbial bacterial agent improved in the saline-alkali land is characterized in that it comprises the following steps:

[0034] 1) Preparation of bacterial agent polymerization aqueous solution: prep...

experiment example 2

[0044] In 2015, 3 farmers including Liu Liguo in Zhengdian Town, Leling City, Dezhou City, applied more than 20 mu of the fertilizer described in Examples 1-3. The fertilizer in Comparative Example 1 was a compound biological compound produced by Shijiazhuang Zhongjia Fertilizer Technology Co., Ltd. Organic fertilizer (powder) (organic matter ≥ 45%, nitrogen, phosphorus and potassium ≥ 5%, effective viable bacteria ≥ 550 million / g, medium and trace elements ≥ 10%), according to the application instructions, 50kg / mu; a total of 2 applications during the growth period .

[0045] As can be seen from the table, compared with the fertilizer of comparative example 1, the acidity and alkalinity of the saline-alkali soil after using the fertilizer of Example 1-3 is significantly improved, and the pH value of the soil is reduced by more than 0.3, and wherein the application of the fertilizer of Example 3 can make the saline-alkali soil The pH dropped the most, dropping 0.42. The nutri...

The content of living bifidobacteria is larger than 0.2 billion per gram. The composite microbial agent comprises Bacillus megatherium, Bacillus mucilaginosus, Bacillus laterosporus, Rhizobium astragali and Paecilomyces lilacinus.

Description

technical field [0001] The invention relates to the field of fertilizers, in particular to a microbial agent for improving saline-alkali land and a preparation method thereof. Background technique [0002] The activating conditioner for repairing saline-alkali beach soil has comprehensive nutrients, which can improve the soil and improve the soil compaction caused by the use of chemical fertilizers. Improve soil physical and chemical properties, enhance soil water retention, fertilizer retention, and fertilizer supply capabilities. The beneficial microorganisms in the activation conditioner for repairing saline-alkali beach soil enter the soil and form a symbiotic multiplication relationship with the microorganisms in the soil, inhibit the growth of harmful bacteria and transform them into beneficial bacteria, interact and promote each other, and play a synergistic effect on the group , Beneficial bacteria produce a large number of metabolites during the growth and reproduc...
