Problems solved by technology

Although the above-mentioned technologies have their own different characteristics, they all have the following problems to varying degrees: 10-35% of polyacrylamide and acrylate, etc., the dosage is too large, the cost is high, and the long-term use of a large area will cause serious pollution to the soil environment At the same time, it also poses a certain threat to human health; at the same time, fertilizers contain a lot of sodium salts, and a large amount of use may cause soil salinization

Embodiment 1

[0018] First prepare chemical fertilizer, by weight urea: diammonium phosphate: potassium sulfate=2:1:1 mixing;

[0019] Then prepare the mixed microbial bacterial agent, with Lactobacillus sporogenes, Bacillus megaterium, Bacillus licheniformis respectively through inclined-plane activation, expansion culture, centrifugal concentration according to conventional methods, by volume ratio Lactobacillus sporogenes bacterial liquid: Bacillus megaterium bacterial liquid: licheniformis Bacillus bacteria solution = 1:1:1 mixed to obtain mixed microbial bacteria agent;

[0020] Prepare the water-retaining agent mixture, mix by mass ratio polyacrylamide: sodium alginate: agar=6:3:1;

[0021] According to the percentage by weight, 22% of the weathered coal and 5% of the mixture of chemical fertilizers such as urea, diammonium phosphate and potassium sulfate are respectively crushed by a pulverizer and mixed with 60% of dry sheep manure, and the moisture content of the mixed material is ...

Embodiment 2

[0025] Preparation of chemical fertilizers, mixing microbial inoculum and water retaining agent mixture, all carried out according to Example 1;

[0026] According to the percentage by weight, 40% of weathered coal and 4% of the mixture of chemical fertilizer urea, diammonium phosphate and potassium sulfate are respectively crushed by a pulverizer and mixed with 50% of dry sheep manure, and the moisture content of the mixed material is adjusted to 60%. , carry out compost fermentation, compost for 40 days, and the raw materials are completely decomposed;

[0027] After pulverizing the decomposed raw materials, pass through a 80-mesh sieve to obtain a powder, then add 5% bentonite and 1% water-retaining agent of a mixture of polyacrylamide, sodium alginate and agar, mix well and then granulate, and dry at 210°C To the water content of 8%, after cooling, the granules are obtained;

[0028] The obtained granules are sprayed with 30ml of mixed microbial agent per 1kg. Afte...

Embodiment 3

[0030] Preparation of chemical fertilizers, mixing microbial inoculum and water retaining agent mixture, all carried out according to Example 1;

[0031] According to the percentage by weight, 35% of weathered coal, 5% of the mixture of chemical fertilizers such as urea, diammonium phosphate and potassium sulfate are respectively crushed by a pulverizer and mixed with 54% of dry sheep manure, and the moisture content of the mixed material is adjusted to 60%. , carry out compost fermentation, compost for 35 days, and the raw materials are completely decomposed;

[0032] After pulverizing the decomposed raw materials, pass through an 80-mesh sieve to obtain a powder, then add 5% bentonite and 1% water-retaining agent of a mixture of polyacrylamide, sodium alginate and agar, mix well and then granulate, and dry at 150°C To the water content of 8%, after cooling, the granules are obtained;

[0033] The obtained granules are sprayed with 40ml of mixed microbial agent per 1kg...

Abstract

The invention relates to water retention type humic acid bio-organic fertilizer and a preparation method. The raw materials of the fertilizer comprise decomposed coal, dried sheep manure, chemical fertilizer, bentonite, water-retaining agents and mixed microbial agents, the fertilizer is prepared through the composting process, granulation process, spray absorption functional bacteria agent process and low temperature drying process, and according to the decomposed coal in the fertilizer, by utilizing coal wastes, the recycle of the wastes is achieved; meanwhile, by using the fertilizer, the soil can be fertilized, and the drought resistance capacity of crops and yield can be improved. The water retention type humic acid bio-organic fertilizer contains abundant humic acid and functional microorganisms; the soil can be improved, and meanwhile the crop yield, the crop quality and the drought resistance capacity of the crops can be improved.

Description

technical field [0001] The invention relates to a water-retaining humic acid bio-organic fertilizer and a preparation method thereof, belonging to the field of fertilizers. Background technique [0002] In the past few decades, due to the pressure of increasing grain production, my country has had to increase the multi-cropping index of agricultural land, which has made farmland barren to varying degrees. One of the important indicators is that the organic matter content in the soil has decreased, and there is an urgent need for organic matter supplementation. The most effective way to replenish organic matter in farmland soil is to increase the application of bio-organic fertilizers and reduce the amount of chemical fertilizers. Humic acid fertilizer is a new type of organic fertilizer. It is the development direction of ecological agricultural fertilizer in the 21st century. It has achieved obvious effects of increasing production and improving quality in agricultural prod...
