Problems solved by technology

Although the content is small, there is also pollution to the environment; large amounts or long-term application of lime alone in agriculture will cause soil compaction and form "lime slabs", and the cost of applying lime at the same time is too high for farmers in poor areas

Embodiment 1

[0039] Step (1): Compound microbial agents such as Bacillus megaterium and Bacillus subtilis and polyglutamic acid are prepared in a mass ratio of 1:1 (the mass ratio of compound microbial agents to polyglutamic acid) to prepare a mixed solution;

[0040] Step (2): The mixed solution is subjected to a spray-drying and embedding process to prepare a composite microbial agent microcapsule containing 5 billion effective viable bacteria / g, which is ready for use;

[0041] Step (3): Mix 25% potassium humate, 20% zeolite powder, and 50% calcium magnesium phosphate fertilizer, and then spray) 5% water to prepare a mixed material;

[0042] Step (4): turn the mixed materials into piles and mature for 10-15 days, then dry, pulverize, and pass through a 100-mesh sieve to obtain a powdery mixture;

[0043] Step (5): uniformly mix 95% of the powdery mixture and 5% of the microcapsules of the compound bacterial agent to obtain the anti-soil acidification organic fertilizer additive of the p...

Embodiment 2

[0049]Step (1): Compound microbial agents such as Bacillus megaterium and Bacillus polymyxa and polyglutamic acid are prepared in a mass ratio of 2:1 (mass ratio of compound microbial agents to polyglutamic acid) to prepare a mixture ;

[0050] Step (2): The mixed solution is subjected to spray drying and embedding process to prepare 8 billion / g microcapsules of composite bacterial agents for future use;

[0051] Step (3): Mix 25% nitro humic acid powder, 30% silicon-calcium powder, and 40% calcium magnesium phosphate fertilizer, and then spray 5% water to prepare a mixed material;

[0052] Step (4): turn the mixed materials into piles and mature for 10-15 days, then dry, pulverize, and pass through a 100-mesh sieve to obtain a powdery mixture;

[0053] Step (5): uniformly mix 97% of the powdery mixture and 3% of the microcapsules of the compound bacterial agent to obtain the anti-soil acidification organic fertilizer additive of the present invention.

[0054] In the step (...

Embodiment 3

[0056] Step (1): compound microbial agents such as Bacillus licheniformis and Bacillus subtilis with polyglutamic acid in a mass ratio of 2:1 to prepare a mixed solution;

[0057] Step (2): The mixed solution is subjected to spray drying and embedding process to prepare 8 billion / g microcapsules of composite bacterial agents for future use;

[0058] Step (3): Mix 25% nitro humic acid powder, 30% shell powder, and 40% calcium magnesium phosphate fertilizer, and then spray 5% water to prepare the mixed material;

[0059] Step (4): turn the mixed material into piles and mature for 10 days, then dry, pulverize, and pass through a 100-mesh sieve to obtain a powdery mixture;

[0060] Step (5): uniformly mix 97% of the powdery mixture and 3% of the microcapsules of the compound bacterial agent to obtain the anti-soil acidification organic fertilizer additive of the present invention.

[0061] In the step (3), the pH value of the mixed material is controlled at 6-8.

Abstract

The invention relates to a soil-acidification-resistant organic fertilizer additive and a preparation method thereof. The additive is prepared through the steps of mainly using zeolite powder, low-grade calcium magnesium phosphate fertilizer, waste resource shells, calcium silicon powder and humic acid powder as raw materials, mixing, fermenting, curing, drying, crushing and scientifically combining and mixing with spray-dried embedded functional composite microbial agent microcapsules. After organic fertilizers added with the additive are applied into acid / acidified soil, the physical fertility, the biological fertility and the chemical fertility of the soil can be improved and the acid resistance of the soil is improved. The additive and the fertilizer with the additive are safe, effective and highly functional. The application of the additive removes the threat of acid / acidified soil to the agricultural production, the ecological environment and the human health from the angle of nutritionists of a food chain.

Description

technical field [0001] The invention relates to a soil additive and a preparation method thereof, in particular to an anti-soil acidification organic fertilizer additive and a preparation method thereof. Background technique [0002] Soil acidification may be caused by soil parent material, natural environment, blind fertilization and traditional empirical fertilization, etc. The area of ​​acidified / acidic soil in my country is about 1.5 billion mu, and the pH value of most of the soil is less than 5.0 or even 4.5, and The area is still expanding. In addition, relevant studies have found that the pH value of the soil in my country's main farmland has dropped by an average of about 0.5 units in the past 20 years, which is equivalent to an increase of 2.2 times in soil acidity (H+). Among them, the soil acidification of economic crop system is more serious than that of grain crop system; even the calcareous soil, which was considered insensitive to acidification in the past, a...
