A white alundum hyperfine abrasive micropowder preparation method adopts aluminum hydroxide as raw material to perform calcining, crushing, pickling, grading and drying so as to obtain the finished product; in regard to micropowder with a particle size of less than 40 microns; hydraulic sedimentation method is used for grading, the grading is performed from thin grades to thick grades in turn, and first thin grades are divided and then thick grades are divided until the whole grades are divided. The grading method of the invention strictly controls the slurry concentration, the settling time and the siphon height and adds high effective dispersant at the same time; the dispersant molecules are penetrated among agglomerated particles in water and coated around all the particles in different sizes, and owning to the repulsion of molecular electric charges of the dispersant, the particles can not be agglomerated together so that the accuracy of grading is increases and the finished product can maintain loose state.

The present invention proposes a method for breeding high-quality Agaricus bisporus, which breaks through the traditional breeding method of Agaricus bisporus, and prefabricates the soil-covering net layer; the three-dimensional net cloth is placed flat on the plane, and the upper layer is adjusted manually or by a clamping device. Position the edge of the mesh, pull up the upper mesh, and keep the lower mesh in contact with the plane; then put the earth covering material in the container bowl, so that the earth covering material can be filled into the adjacent container through the gap between the wire ropes. Between the bowls, support the soil covering material in the bowl and the entire three-dimensional mesh; then list the filled soil mesh layers together layer by layer; dry and sterilize the listed soil mesh layers; The net layer is sprayed and wetted from top to bottom; the fermentation material is placed in the inclined box monomer for the second fermentation to make a fermentation medium; bacteria are sown on the surface of the fermentation medium; the soil net layer is covered on the fermentation medium. surface of the medium. The invention can breed higher quality Agaricus bisporus.

The invention discloses a plate-shaped cultivating bag film mulching method for a tea-oil tree young stand. The method comprises the following steps of (1) time selection, (2) agricultural film preparation, (3) weeding and bag cultivation, and (4) agricultural film mulching. The time selection is carried out two months after planting of tea-oil trees. According to the agricultural film preparation step, a polyethylene film is cut into square pieces with the length and the width both of 1.1m, and cross-shaped cuts with the transverse and longitudinal lengths both of 15cm are cut in the middle for standby application. According to the weeding and bag cultivation step, weeds around the tea-oil tree saplings are removed, surface soil is harrowed and smashed into fine soil and is held together to form soil mounds which are similar to a plate shape, and an annular groove is hoed along the periphery of each soil mound. According to the agricultural film covering step, the agricultural film with the cross-shaped cuts cover the plate-shaped soil mounds by crossing the tea-oil tree saplings, 4 to 6 air holes with the diameter of 1cm are stabbed in the agricultural film, a small amount of loosened soil covers the peripheries of the air holes of the film, and the periphery of the film is compacted through soil blocks. The plate-shaped cultivating bag film mulching method for the tea-oil tree young stand has the advantages that evaporation of soil moisture can be reduced during high temperature and drought periods, ground temperature on the peripheries of the tea-oil tree saplings can be improved during winter severe cold time, the effects of activating soil, preserving heat, and reducing fertilizer competition of weeds are performed, and the survival rate of the tea-oil tree saplings is improved.

The present invention proposes an artificial breeding method of high-quality Agaricus bisporus, which breaks through the traditional breeding method of Agaricus bisporus, and pre-fabricates a plurality of soil-covering net layers of different thicknesses and single-layer soil-permeable cloth; evenly distributed lanyards; the filled soil net layer and the single-layer soil permeable cloth are arranged layer by layer; the listed soil net layer is dried and sterilized; the listed soil net layer is arranged by Spray wetting from top to bottom; the upper end of the first pillar is formed with a card slot for limiting the tilt box, the suspension beam extends along the length of the bracket and is fixed on the upper end of the second pillar, and the suspension beam is provided with multiple hanging beams The protruding column hung by the rope; the inclined box includes a plurality of box monomers arranged along the length direction of the support, and the length and width of the box monomers correspond to the length and width of the covering soil net layer; the bacteria are sown on the surface of the fermentation medium; When covering the surface of the fermentation medium with the soil net layer, remove the single-layer soil-permeable cloth.

The invention provides a waterproof construction method characterized by a heat pipeline sleeved in a steel sleeve pre-buried in an external wall and a waterproof system structure. The waterproof construction method includes steps as follows: the steel sleeve is pre-buried in the wall; a heat insulation pipeline is sleeved in the steel sleeve and fixed; the clearance between the steel sleeve and the heat insulation pipeline is filled with a functional material; the functional material at least includes a set of water swellable rubber strip layers; baffles are arranged on the outer sides at both ends of the steel sleeve; the outer sides of the baffles are waterproof, and raiser blocks used for supporting are arranged and tightly clung to the baffles; a waterproof coiled material is laid inan intersection area of the external wall body and the heat insulation pipeline, and wrinkles are formed at the corner of the waterproof coiled material, so that the waterproof coiled material and the outer wall of a direct-buried heat insulation pipeline can be combined and wound tightly; the waterproof coiled material is externally provided with a protection layer; a local reinforcement protection facility is arranged on the outer side at the wrinkle part at the corner of the waterproof coiled material; and the backfilling is performed. The structure is an integral system structure established upon the method. The construction method is simple and short in period, and lowers the investment; the daily maintenance is convenient, the waterproof effect is excellent, the service life is long, and the operation management cost is low; and further, the requirement for the operation of a heat pipeline network can be satisfied.
