The invention relates to a rapid propagation method for tissue culture of phoebe zhennan. The rapid propagation method comprises the following steps: (1) selecting seeds; pre-treating the seeds and immersing the seeds in a base material for germination; after embryos are differentiated, transferring and culturing; (2) carrying out bud induction culture by taking tender coppice shoots as explants; (3) cutting the newborn tender seedlings into sections and carrying out rooting culture; (4) inoculating adventitious root buds into a proliferation culture medium and carrying out proliferation culture; (5) inoculating the adventitious root buds obtained by the proliferation culture into a rooting culture medium and carrying out rooting culture; (6) domesticating and transplanting. According to the rapid propagation method, the rooting culture of seedling stem section tissues is combined with adventitious root bud induction proliferation culture to reasonably domesticate and circularly take materials, so as to keep complete genomes of the phoebe zhennan, improve the survival rate and the quality of the phoebe zhennan and increase the growing speed of the phoebe zhennan.

The invention provides a bamboo-wood straw and a manufacturing method. A bamboo-wood straw main body is of a straight-strip tubular structure with a uniform wall thickness, one end of the bamboo-woodstraw main body is cut into a flat cut to serve as a drinking port, the other end of the bamboo-wood straw main body is cut into an inclined cut to serve as a puncturing port, raw materials of the bamboo-wood straw are ripe bamboo or wood which is uniform and consistent in texture, and include sandalwood, beech, oak, phoebe zhennan, ormosia henryi and the like. According to the bamboo-wood straw,a new structure suitable for combination and processing is adopted, requirements for natural formation of the raw materials are small, common materials can be directly adopted, the requirements for selecting materials are small, and the material cost is greatly reduced; the raw materials are environment-friendly, easy to recycle and recyclable, and the bamboo and the wood have the characteristic of environmental protection, and can be conveniently reused in many fields after being used as disposable straws; the processing method is suitable for large-scale production; and the requirements of the raw materials are relatively low, standardized production can be realized, and the quality of products is stable and controllable.

The invention discloses a vacuum drying method for a phoebe zhennan board. The vacuum drying method comprises the steps of preheating, steam heating, vacuumization, humidification treatment and the like. The preheating time is proportional to the board thickness. In the step of steam heating, the steam temperature is 50-70 DEG C, and a psychrograph is introduced into the process to monitor the humidity in a drying device. The vacuum degree of the drying device is kept at 0.008-0.012 MPa during vacuumization. When humidification treatment is conducted, the vapor temperature is 55-60 DEG C, the temperature difference of the psychrograph is controlled to be 5-6 DEG C, and the treatment time is 10-20 h. By adoption of the drying steps, the phoebe zhennan board cannot crack, color changes are small, the drying time is short, and the drying quality is high.

The invention relates to a method for inducing rapid callusing of phoebe zhennan. The method comprises the following steps: by taking tender phoebe zhennan leaves as explants, collecting the explants,cleaning, sterilizing, cutting, inoculating, and carrying out dark culture and light culture, thereby completing rapid induced callusing of the phoebe zhennan. The callusing induction rate is up to 98.1% at most, a remarkable greening degrees and a callusing growth amount are achieved, and bases and related technical support can be provided for future phoebe zhennan callus induction, tissue culture for nursery stock reproduction, stock breeding acceleration and market requirement meeting.

The invention relates to the technical field of sports goods, and aims to disclose a phoebe zhennan table tennis bat with a good springback effect. Key points of the technical scheme are as follows: the table tennis bat comprises a batting plate and a racket handle for holding; the batting plate comprises phoebe zhennan panel layers, phoebe zhennan composite force material layers, reinforced composite fiber layers and a core plate layer. The upper surface and the lower surface of the core plate layer are respectively glued with the reinforced composite fiber layer in a gluing manner; the phoebe zhennan composite force material layer is respectively glued with the surface of one side, deviating from the core plate layer, of the reinforced composite fiber layer in a gluing manner; the phoebezhennan panel layers are glued to the surfaces of the sides, deviating from the reinforced composite fiber layers, of the phoebe zhennan composite force material layer in an adhesive mode, and the racket handle is glued to the phoebe zhennan panel layers in an adhesive mode. The table tennis bat has the advantages of being light in structure, high in strength, good in batting rebound resilience and long in service life.

The invention discloses a petroleum drilling additive with polypropylene ammonium salt and a preparation method of the petroleum drilling additive. The petroleum drilling additive is characterized by comprising the following components in parts by weight: 100-200 parts of acrylic fibers, 600-800 parts of water, 7-12 parts of polyacrylate, 0.8-1.2 parts of polyacrylamide, 5-10 parts of a cross-linking agent and 50-60 parts of phoebe zhennan powder. By adopting the petroleum drilling additive, the filter loss and the apparent viscosity of mud can be further reduced, potential safety hazard caused by the situation that hydrolysis polyacrylonitrile ammonium salt can be produced under a relatively large pressure condition (about 2.1MPa) can be avoided, the amount of additives in the mud can be reduced, the potency ratio of a product is increased, and thus the drilling cost can be effectively lowered.

The invention discloses water-based paint for phoebe zhennan furniture, and belongs to the technical field of water-based paint. The water-based paint is prepared from the following ingredients in parts by weight: 60 to 70 parts of water-soluble resin, 20 to 24 parts of acrylic acid, 18 to 20 parts of polyethyleneglycol, 23 to 25 parts of modified nano-SiO2, 20 to 26 parts of modified upland soil,5 to 6 parts of nano-zinc oxide, 9 to 13 parts of lanthanum carbonate, 8 to 12 parts of sodium carbonate, 6 to 10 parts of cerium nitrate, 5 to 9 parts of phenylethanol oleate, 3 to 5 parts of polyoxypropylene glycerol ether, 10 to 16 parts of sodium alginate and 40 to 50 parts of sterile water. The raw materials are reasonably matched; the finally prepared water-based paint has the advantages ofhigh adhesion capability, good dispersion performance, ultrahigh transparency, high light resistant performance, good film forming performance, cracking difficulty, almost no volatile solvents, highsafety and good market popularization values.
