The invention relates to an emission reduction dry-type culture method for producing nonreactive pork. The method uses pig feeds, which contain feedstuff additive premix, and active water agent to feed the pigs. An organic adhesive layer is laid inside a pig shed. The active water agent contains natural plant extract and bacillus subtilis, and is drunk by the pigs through a leak protection and filtering water device arranged inside the pig shed. The feedstuff additive premix contains NSP enzyme, micro-ecological agent, plant extract and acidifier. The method can prevent the pigs from having intestinal bacteria and viral diseases and respiratory diseases, and reduce the discharge of fecaluria and living water, harmful gas produced by pig fecaluria and stench, and through which prevents the breeding of flies. At the same time of producing nonreactive port, the method can reduce the pollution caused by excreta.

The invention discloses application of a reagent for inhibiting circ_CLASP2 (Cytoplasmic Linker Associated Protein 2) in preparation of a preparation for treating nasopharyngeal darcinoma and the preparation. A research proves that the circ_CLASP2 is inhibited in nasopharyngeal darcinoma cells, and the proliferation, invasion and metastasis of the nasopharyngeal darcinoma cells can be inhibited. Therefore, a circ_CLASP2 inhibitor is used for treating the nasopharyngeal darcinoma and has profound clinical significance and an important popularization and application prospect.

The invention discloses a photocatalytic anti-fog sand-wall shape negative ion coating. The photocatalytic anti-fog sand-wall shape negative ion coating comprises, by weight, 15-60 parts of an anti-fog base material, 10-70 parts of particle aggregates and 10-30 parts of a binder. Smoke dust, oil dust, sand dust and the like in fog can be removed through the anti-fog base material, and negative ions in the air are increased. The sand-wall coating has the anti-fog and attractive effect, simpleness and efficiency in preparation method are achieved, and the sand-wall shape coating is multifunctional.

The invention relates to a bottom sowing-type mariculture facility which is suitable for the sea area with silt bottom, in particular to a bottom sowing-type raft frame and a net cage for marine bivalve mollusks, sea cucumbers or mixotrophic culture of marine bivalve mollusks and sea cucumbers. The facility is provided with a PVC pipe, a polyethylene rope for fixing the PVC pipe, a webbing, a stake or an anchor for fixing the facilities, a rope fixed on the stake or the anchor, and a fixable floating ball which is connected to the rope and floats on the surface of water; the PVC pipe is fixed on the polyethylene rope in parallel, the polyethylene rope is arranged in parallel, is perpendicular to the PVC pipe, is positioned at the upper side and the lower side of the two terminals of the PVC pipe and forms the structure similar to a 'soft ladder'; the 'soft ladder' is externally covered by the webbing, and a plurality of independent net cages are formed by combining the PVC pipe, the polyethylene rope and the webbing; the two ends of the undrawn 'soft ladder' are fixed at the bottom of the sea by the stake or the anchor respectively, and the floating ball is fixed at the two ends of the 'soft ladder' by the rope. The facility can effectively prevent the enemies and reduce the influence of storm and ocean current, thus being convenient for management and harvest and favorable to the comprehensive utilization of mariculture area.

The invention discloses a cultivation method for a gastrodia elata seed propagation germination promoting fungus third-level stain. The method comprises ten steps of preparing, soaking, draining, stirring, bagging, covering, sterilizing, cooling, inoculating a second-level stock culture and culturing. According to the method, the problems of severe interference of infectious microbe and complex formula existing in the conventional gastrodia elata seed propagation germination promoting fungus culturing process are solved. The invention further discloses a culture medium for the gastrodia elata seed propagation germination promoting fungus third-level stain. The culture medium consists of the following raw materials: 72-74 percent of cyclobalanopsis leaves and 26-28 percent of wood flour, wherein the sum of the masses of the components is 100 percent. According to the culture medium, the wood flour supplies sufficient nutrients for the growth of the germination promoting fungus at the initial growing stage of the germination promoting fungus, so that the survival rate of the germination promoting fungus is increased; the cyclobalanopsis leaves containing enough nutrients can be used for supplying nutrients to the growth of the germination promoting fungus continuously for a long time along with the growth of the germination promoting fungus, so that rapid growth of the germination promoting fungus is ensured; meanwhile, the cyclobalanopsis leaves are easy to obtain, and fresh cyclobalanopsis leaves contain a small quantity of infectious microbe, so that the invasion of the infectious microbe in the culturing process of the germination promoting fungus can be reduced effectively.

The invention provides a process for producing a door curtain material, which comprises delivery of polyester fiber grey cloth, double-face coating treatment, pre-plasticizing and gelling, planishing and cooling, primary coating of a horizontal coating head, plasticizing treatment, cooling and shaping, secondary coating of the horizontal coating head, plasticizing treatment, embossing, cooling, winding, surface treatment and preparation. The process combines net sandwich cloth coating and surface treatment process, is complete relatively to common coating processing, can process a vertical coating, a surface layer and a bottom layer, reduces the intrusion of ultraviolet rays on the coating by adopting the surface treatment process on the one hand, can prevent plasticizing agent from being transferred to the surface of a product on the other hand so as to achieve the antifouling effect and achieve the aim of self-cleaning by means of rainwater; and the product has good air tightness and superior abrasion-resisting property, is suitable for outdoor application, and has long service life and remarkable economic benefit.
