Problems solved by technology

If my country continues to increase the input of chemical fertilizers and pesticides to achieve the goal of high and stable yields, the agricultural ecological environment will become worse and worse, and it will fall into what is called the "violent circle of petrochemical agriculture" in the world, which will ultimately be detrimental to the stability of food production.

preparation example Construction

[0058] A preparation method of microbial organic fertilizer, the steps are as follows:

[0059] Step 1, first crush the straw into 5-7mm particles and set aside;

[0060] Step 2: Take 65-70% of straw, 12-15% of flour, 1% of lime, and 0.5% of potassium dihydrogen phosphate by weight, mix and stir for 2 minutes, then add 13.5-21.5% of water, and mix and stir for 3-5 minutes;

[0061] Step 3. Send the mixture made in step 2 into the pressure vessel, and send steam into the pressure vessel to increase the air pressure in the pressure vessel to 1.5-2Mpa, the temperature to 160-180°C, and sterilize for 10 minutes. Then the material is sent to the fermentation bin;

[0062] Step 4. After the material is sent into the fermentation bin, add liquid mixed strain NEM according to 5-10% of the total weight of the fermentation material in the fermentation bin, and perform anaerobic culture for 72-96 hours at a culture temperature of 37°C. When the pH value is 4.5- 5.0, when the number of ...

Embodiment 1

[0064] Take 65% of crushed corn stalks, 10% of sorghum stalks, 10% of bean stalks and 15% of wheat stalks by weight, mix them to form a straw mixture, and set aside;

[0065] Take 70% of corn flour and 30% of soybean flour by weight, mix them to form a flour mixture, and set aside;

[0066] Take 65% of straw mixture, 12% of flour mixture, 1% of lime, and 0.5% of potassium dihydrogen phosphate by weight, mix and stir for 2 minutes, then add 21.5% of water, mix and stir for 3-5 minutes to make a fermentation mixture ;

[0067] Send the prepared fermentation mixture into the pressure vessel, send steam into the pressure vessel, raise the air pressure in the pressure vessel to 1.5-2Mpa, raise the temperature to 180°C, sterilize for 10 minutes, and then send the fermentation mixture to into the fermentation bin;

[0068] After the fermentation mixture is sent into the fermentation chamber, 10% of the total weight of the fermentation material in the fermentation chamber is inserte...

Embodiment 2

[0070] Take 62% of crushed corn stalks, 10% of sorghum stalks, 10% of bean stalks, and 18% of wheat stalks by weight, and mix them to form a straw mixture, which is set aside;

[0071] Take 50% of corn flour and 50% of soybean flour by weight, mix to form flour mixture, and set aside;

[0072] Take 70% of straw mixture, 15% of flour mixture, 1% of lime, and 0.5% of potassium dihydrogen phosphate by weight, mix and stir for 2 minutes, then add 13.5% of water, mix and stir for 3-5 minutes to make a fermentation mixture material;

[0073] Send the prepared fermentation mixture into the pressure vessel, send steam into the pressure vessel, raise the air pressure in the pressure vessel to 1.5-2Mpa, raise the temperature to 160°C, sterilize for 10 minutes, and then send the fermentation mixture to into the fermentation bin;

[0074]After the fermentation mixture is sent into the fermentation chamber, 5% of the total weight of the fermentation material in the fermentation chamber i...

Abstract

The invention discloses a microorganism organic fertilizer, which consists of straw, flour, lime, potassium dihydrogen phosphate, water and liquid mixed strain (NEM), wherein the weight percentages of the straw, the flour, the lime, the potassium dihydrogen phosphate and the water are as follows: 65 to 75% by weight of straw, 12 to 15% by weight of flour, 1% by weight of lime, 0.5% by weight of potassium dihydrogen phosphate and 13.5 to 21.5% by weight of water, and the addition amount of the liquid mixed strain (NEM) accounts for 5 to 10% by weight of the total weight of the straw, the flour, the lime, the potassium dihydrogen phosphate and the water. According to the invention, plenty of phosphatase, protease, polypeptide amino and other substances are generated in mixed fermentation, the utilization rate of fertilizers is enhanced, the growth of plant root is simultaneously promoted so that the plant root absorbs more nutrients, the growing plant feeds a large number of nutrients back to soil through the root owing to the favorable development of the root, thereby promoting the microbial proliferation in soil, therefore, such a sound cycle facilitates soil improvement and achieves the effect of soil repair; furthermore, the microorganism organic fertilizer is simple in production process, low in cost and convenient for popularization and application.

Description

technical field [0001] The invention relates to a microbial organic fertilizer, in particular to the technology of using microorganisms to inoculate soil for soil restoration, that is, using straw as a main carbon source to carry out multi-bacteria mixed fermentation to produce highly active organic fertilizer and its preparation method. Background technique [0002] At present, in my country's agricultural planting, a large number of chemical fertilizers are used, which not only causes environmental pollution, but also causes a large amount of energy consumption. In ecological agriculture using low-carbon economy, inoculating beneficial bacteria into soil to increase soil enzyme activity, increase the utilization rate of organic fertilizers, and reduce the use of chemical fertilizers are important measures for soil restoration. The liquid bacterial agent has the characteristics of high activity and easy use, and is one of the most effective restoration agents for repairing ...
