The invention provides a smoke filter material. The smoke filter material comprises a first cellulose diacetate film layer, a lipophilic polymer material film layer and a second cellulose diacetate film layer in sequence along the entry direction of the smoke. The invention also provides a preparation method and application of the smoke filter material. The provided smoke filter material improvesthe adsorption function for the tar oil and can simultaneously filter smoke particles and harmful gas; the moisture of the smoke of the smoke filter material is increased to improve the wetness degree; when the smoke filter material is applied to a cigarette filter, the discomfort of dryness caused by the smoke is lowered, the taste is improved, and the smoke filter material has a wide applicationprospect and higher application value.

The invention provides an aromaticity bamboo charcoal fiber and a preparation method thereof in order to meet demands of clients in a product market and solve the problem that the conventional bamboo charcoal viscose fiber is poor in spinning property. The aromaticity bamboo charcoal fiber is characterized in that a finished product is obtained by taking cellulose fiber pulp as a raw material, mixing an aromaticity bamboo charcoal solution and viscose through injection before spinning and performing wet spinning and post-treatment, wherein the aromaticity bamboo charcoal solution is prepared by mixing fragrant masterbatches and a bamboo charcoal solution; the fragrant masterbatches contain perfumes; the fragrant perfume content of the fiber is 0.01-10 percent; the bamboo charcoal content is 0.1-10 percent; the ammonia absorption rate is more than or equal to 50 percent; the air permeability is more than or equal to 500mm / s; the color fastness to washing is of 4-5 level. The aromaticity bamboo charcoal fiber disclosed by the invention has the functions of bacterium and ultraviolet prevention and deodorization, is high in air permeability and hygroscopicity, can effectively and continuously scatter fragrance and has the effects of relieving pressure and enabling people to be invigorating.

The invention discloses an ancient tea tree propagation method. The method comprises the steps of pretreatment of a tree for seed collection, transplanting, and post-transplanting management. According to the method, a solution topical application method is adopted for dropping heteroauxin, cytokinin and gibberellins at branch buds, growth of the apical tissue of an ancient tea tree can be effectively promoted, and the problem that cutting propagation survival rate is not high is effectively solved through growth of the branch buds wrapped in a nutrient bag; then magnetization treatment is adopted, the adsorption function of the ancient tea tree can be effectively improved, the magnetized ancient tea tree can adsorb ferromagnetic substances and paramagnetic substances in soil to the root during planting, the capability of absorbing water and a fertilizer and performing photosynthesis of the ancient tea tree is enhanced, and the soil environment of the ancient tea tree is improved; and then in the later stage, fertilization and topdressing treatment are conducted, the survival rate of the ancient tea tree is substantially increased, and the problems that the ancient tea tree is high in propagation cost, incapable of maintaining good traits, and unsatisfactory in propagation effect are solved.

The invention relates to a heavy metal adsorbent technology. Particularly, Simply aired biogas residues are inoculated with fungi for mixed culture, after fungus aerial mycelia constantly grow and breed on the surfaces of the biogas residues until one layer is covered, the biogas residues are dried, crushed, ground and sieved, and the fungus modified biogas residue heavy metal adsorbent is obtained. Aspergillus niger mycelia have adsorption performance, the surfaces of biogas residues are inoculated with the aspergillus niger mycelia, and the efficient heavy metal adsorbent with a rough surface and a mesoporous structure can be obtained. The prepared modified biogas residue heavy metal adsorbent has the advantages of low cost, excellent adsorption performance and the like.
