The invention provides a preparation method and an application of multi-effect anti-biological inoculants for controlling crop soil-borne diseases. According to the preparation method, trichoderma viride strains and endogeny bacillus subtilis having antagonistic action to pathogenic bacteria of the crop soil-borne diseases are used as parent inoculants, and light calcium carbonate is used as a carrier to prepare the anti-biological inoculants. The anti-biological inoculants are mainly used for controlling various crop soil-borne diseases caused by pathogenic fungi including fusarium, pythium, rhizoctonia and the like, and have multiple functions of improving self resistance and increasing the output of plants. By adopting the preparation method, the anti-biological inoculants are short in production cycle, stable and lasting in control effect and pollution-free to the environment without residues to crops.

The invention belongs to the technical field of agricultural fertilizers and particularly relates to a biomass-charcoal basal fertilizer and a preparation method therefor. The biomass-charcoal basal fertilizer is prepared from the following raw materials in parts by weight: 15-20 parts of biomass charcoal, 20-30 parts of urea, 20-30 parts of ammonium dihydrogen phosphate, 15-25 parts of potassiumsalt, 5-10 parts of bentonite and 1-5 parts of calcium sulfate. According to the preparation method for the biomass-charcoal basal fertilizer, a granulating process has physical and chemical double reactions, an amido bond of urea and a nitrogen-phosphorus bond of ammonium dihydrogen phosphate in the charcoal basal fertilizer are bonded to a charcoal group to change chemical shift under high-temperature steam reaction conditions, nutrients and a carbon skeleton are bonded to each other, the bonding among the raw materials is closer, and thus, the fertilizer effect is prolonged.

The invention provides Ca / Fe / GO / biomass charcoal, carbon-based slow-release fertilizer special for corn and application of the carbon-based slow-release fertilizer, and belongs to the technical fieldof fertilizer. The Ca / Fe / GO / biomass charcoal is prepared by the following steps: mixing biomass raw material slag powder with calcium chloride, ferric chloride and graphene oxide, carbonizing the mixed material at 100 to 120 DEG C for 1 to 2hours and at 500 to 600 DEG C for 4 to 6 hours in sequence, and washing the carbonized product to be neutral to obtain modified biomass charcoal. The carbon-based slow-release fertilizer special for the corn is prepared from the following components in parts by weight: 15 to 20 parts of the modified biomass charcoal, 5 to 8 parts of calcium cyanamide, 35 to40 parts of superphosphate, 20 to 30 parts of potassium salt, 6 to 9 parts of plant ash, 5 to 10 parts of bentonite, 1 to 5 parts of calcium sulfate and 3 to 7 parts of a mushroom dreg composted material. The slow-release fertilizer provided by the invention is not easily broken, and the fertilizer effect is prolonged; when the slow-release fertilizer is applied in a corn planting process, the yield is increased by 5% or above and the soil structure can be improved.

The invention discloses a formula and making method of a paste material for a frozen cheese creammy snow cap. The making method comprises the following steps of mixing raw materials of milk, cream andthe like, through combination of intermittent ultrasonic waves with a chopping technology, making semi-finished products of the paste material for a frozen cheese creammy snow cap, and through a decompressing quick-freezing technology, making finished products of the paste material for a frozen cheese creammy snow cap. After being unfrozen, the paste material for a frozen cheese creammy snow capis mixed with coffee cream in a certain proportion, and whipping is performed, so that cheese creammy snow cap, cheese creammy snow cap coffee or other beverages, being delicious, can be made. Throughcombination of the intermittent ultrasonic waves with the chopping technology, the raw materials are heated, and then the heated raw materials are mixed, so that the juice separation rate of the products can be effectively reduced, the emulsifying effect is guaranteed, and the elasticity and the fine and smooth degree of the products can be strengthened; decompressing quick-freezing is performed,so that the temperature of the products can be rapidly reduced, the flavor and the nutritional quality of the products can be maintained, and the shelf life can be prolonged. The formula and the making method are suitable for large-scale industrialized production. The paste material is stable in quality, rich in nutrition, delicious in mouth feel, convenient to use and convenient to transport andsell, and the problems that losses during on-site making are high, the products are instable, and the food hygiene security cannot be guaranteed, are solved.

The invention relates to a blow boiling cold-concentration pool. The blow boiling cold-concentration pool comprises a boiling pool, a blower and a hollow porous plate. The boiling pool is a cuboid with an open-ended upper end. The blower is connected with the hollow porous plate through a pipeline, and the blower is positioned over the liquid surface of a liquid material in the boiling pool. The hollow porous plate is horizontally fixed at the bottom of the boiling pool. The hollow porous plate is a plate-shaped cuboid with five enclosed surfaces and one surface arranged with pores and havinga hollow internal part, and one surface of the pore of the hollow porous plate faces to an open end of the boiling pool. When the cold concentration work is carried out, the to-be-concentrated liquidmaterial is added in the boiling pool, a blower is turned on, a lot of bubbles can be generated at the surface of the hollow porous plate, the bubbles rapidly rise due to buoyancy, the liquid materialpresents a boiling state, and the bubbles rapidly pass through the liquid material and moisture in the liquid material is taken away. The blow boiling cold-concentration pool has the advantages of low cost, simple structure, and high concentration efficiency, and can rapidly concentrate the liquid material which cannot be subjected to high-temperature concentration.

The invention discloses a manufacturing method of a concrete artware with a ceramic texture on a surface. The method comprises the following steps of adopting a blow molding process for blowing thermoplastic plastic into a mold, forming a layer of plastic on the inner surface of the mold, and obtaining a mold used for forming; stirring ultra-high-performance concrete into a slurry, and obtaining aslurry used for forming, wherein the flowability of the slurry is not lower than 300mm; and adding the slurry into the mold for forming, standing after forming, then dry-heating and curing a belt mold, and finally demolding. The surface of the product prepared by the invention has the glossy appearance just like ceramic and the fine and smooth tactility; and in addition, the manufacturing processis simple, the manufacturing cost is low, and industrial production can be carried out conveniently.
