preparation example Construction

[0027] A kind of preparation method of microbial soil remediation agent of the present invention, carry out according to following method steps:

[0028] (1), first corn stalk and wheat straw are pulverized to the powder below 5mm respectively, for subsequent use;

[0029] (2), take corn stalk 50-60%, wheat straw 20-30%, wheat bran 10-20%, rapeseed meal 5-10%, cornmeal 5-10%, lime 1.5-2.5%, dihydrogen phosphate by weight percentage Potassium 0.15% and sodium chloride 0.15%, mixed, then add 20-30% of water, make the moisture of the mixed material reach 25%, make a mixture, and set aside;

[0030] (3), the mixture made in step (1) is sent into the steam explosion pot, and the steam explosion pot door is closed;

[0031] (4) Add high-pressure steam into the steam explosion pot, and discharge the cold air in the steam explosion pot, so that the air pressure in the steam explosion pot rises to 1-2Mpa, the temperature rises to 140-200°C, and the pressure is maintained for 4-6min ;...

Embodiment 1

[0039] Take 60% of corn stalks, 15% of wheat straw, 10% of wheat bran, 7% of cornmeal, 5% of rapeseed meal, 1.7% of lime, 0.15% of potassium dihydrogen phosphate, and 0.15% of sodium chloride by weight, mix well, and press Add 20-30% water by weight to make the water content reach 25%, and the treatment capacity at one time is 10 tons.

[0040] Send the mixed material into the steam explosion pot, and pass high-pressure steam into the steam explosion pot, discharge the cold air and increase the pressure to 1.5Mpa, raise the temperature in the steam explosion pot to 180°C, and keep the pressure for 6 minutes.

[0041] Instantly release the material in the steam explosion pot and send it into the closed italic fermentation chamber. Firstly, the aseptic cold water flat cooling plate and sterile cold air are used to dissipate heat at the same time, so that the temperature of the material drops to 30-37°C, and then the liquid is added. Bacterial classification, the inoculum amount ...

Embodiment 2

[0045] Take 55% of corn stalks, 20% of wheat straw, 12% of wheat bran, 5% of cornmeal, 5% of rapeseed meal, 1.7% of lime, 0.15% of potassium dihydrogen phosphate, and 0.15% of sodium chloride by weight, mix well, and press Add 20-30% water by weight to make the water content reach 25%, and the treatment capacity at one time is 10 tons.

[0046] Send the uniformly mixed materials into the steam explosion pot, and pass high-pressure steam into the steam explosion pot, discharge the cold air and increase the pressure to 1.8Mpa, so that the temperature in the steam explosion pot rises to 200°C, and keep the pressure for 4 minutes.

[0047] Instantly release the raw materials in the steam explosion pot and send them into the airtight italic fermentation chamber. Firstly, the aseptic cold water flat cooling plate and aseptic cold air are used to dissipate heat at the same time, so that the temperature of the materials drops to 30-37°C, and then the liquid is added. Bacterial classif...

Abstract

The invention relates to a microbial soil restorative prepared by fermenting corn stalks, wheat straw, wheat bran, corn meal, rapeseed meal, lime, potassium dihydrogen phosphate, sodium chloride, water and liquid strains in a fermentation bin. The preparation method of the microbial soil restorative comprises the following steps: firstly, crushing the corn stalks and the wheat straw into particleswith diameters smaller than 5 mm; proportionally adding and mixing the wheat bran, the corn meal, the rapeseed meal, the potassium dihydrogen phosphate, the sodium chloride and the lime; then, adding25 percent of water; sending the mixture to an air steamer; adding high-pressure steam to the air steamer so as to increase the air pressure to 1-2 MPa and the temperature to 140-200 DEG C; pressuring for 4-6 minutes; releasing the mixture in the air steamer so that the temperature of the mixture falls to 30-37 DEG C; inoculating 5 percent of strains; fermenting in the fermentation bin at the temperature of 32-37 DEG C for 72 hours; discharging from the bin; and bagging to obtain a finished product. The produced microbial soil restorative contains a great amount of active substances, such asmicroorganisms, and the like, is capable of replacing fertilizer, has the growth-stimulating and disease-resistant functions, increases the yield by more than 20 percent and has low cost and easy industrialized production.

Description

technical field [0001] The present invention relates to a microbial soil remediation agent, in particular to the technology of using microorganisms to inoculate soil for soil remediation, that is, using steam-exploded straw as the main carbon source to carry out mixed fermentation of multi-bacteria to produce highly active soil remediation agent and its Preparation. Background technique [0002] The extensive use of chemical fertilizers not only causes environmental pollution, but also causes a large amount of energy consumption. In ecological agriculture, it is the current soil remediation method to increase soil enzyme activity, improve the utilization rate of soil remediation agents, and reduce the use of chemical fertilizers by inoculating beneficial bacteria into the soil. It is an important measure, liquid bacterial agent has the characteristics of high activity and easy to use, and it is one of the most effective restoration agents for repairing soil and improving soi...
