The invention discloses a special compound organic fertilizer for tobacco. The special compound organic fertilizer mainly comprises the following components in parts by weight: 25-40 parts of maize straws, 10-25 parts of excrements of livestock, 10-15 parts of oil cake, 0.1-0.6 part of urea and 0.1 part of a decomposition agent. The organic fertilizer is mainly prepared by the following steps: pretreating raw materials, performing primary fermentation, performing secondary fermentation, drying and packaging. The fertilizer is applied to the ditch before tobacco plant transplanting, so that growth of the tobacco plants can be obviously promoted, particularly the plant height and leaf length are increased, and the tobacco planting soil is improved; and therefore, the nicotine content of the tobacco leaf is reduced, the quality and appearance quality of the tobacco leaf are improved, the land resources can be effectively protected due to reasonable application of the fertilizer, and a necessary guarantee is provided for sustainable development of the tobacco leaf. The organic fertilizer is particularly suitable for cultivation of high-quality tobacco leaf. In addition, the organic fertilizer disclosed by the invention is wide in source and low in price, the pollution of straw combustion and livestock manure on the environment is reduced, the preparation method is simple and feasible, and the fertilizer is wide in functions and good in effect.

The present invention discloses a feed additive for improving the anti-stress ability of livestock and poultry, and a preparation and a use method thereof. The feed additive comprises the following ingredients by weight: 1-5 parts of vitamin C, 10-15 parts of manyprickle acathopanax root, 5-10 parts of silktree albizia bark, 5-12 parts of common anemarrhena rhizome, 4-10 parts of glossy privet fruit, 6-15 parts of baikal skullcap root, 4-10 parts of tree peony root-bark and 4-10 parts of common andrographis herb. According to the present invention, the feed additive for improving the anti-stress ability of livestock and poultry uses a plurality of Chinese herbal ingredients to compound with vitamin C, significantly enhances the immunity, disease resistance and anti-stress ability of livestock and poultry, regulates the excitement of central nervous system, enhances the resistance of livestock and poultry to stress environment and living environment, and increases the appetite of livestock and poultry and the feed conversion ratio. The feed additive for improving the anti-stress ability of livestock and poultry has characteristics that the feed additive has no drug residue, no drug resistance, no pollution, no toxic side effects, and is safe and reliable; and the feed additive can be prepared from raw materials from extensive sources, is simple and feasible in preparation method, low in cost, convenient to use and high in bioavailability, and has wide application prospects.

The invention relates to a desulfurizer of organic sulfur (such as carbonyl sulfide, thiol, disulphide and the like) for removing hydrocarbon, in particular for removing hydrocarbon with less than six carbon atoms; the desulfurizer comprises gamma-Al2O3 used as a carrier and alkali metal oxide used as an active constituent. The desulfurizer has the advantages of high precision for removing organic sulfur, simple preparation process and low cost, and the organic sulfur can be transferred to carbonyl sulfide with above 95% of conversion rate.

The invention discloses a preparation method of a biomass tar cracking catalyst. The catalyst is prepared from raw materials including iron oxide nanoparticles, octadecyl triethoxysilane, high-carbonorganic matter, rice husk, sodium metaaluminate, nickel nitrate and the like. An iron oxide magnetic material is inserted in preparation of the catalyst, recovery and reuse of the catalyst are facilitated, deposed carbon is diffused and mixed horizontally through combustion of the high-carbon organic matter, doping is more uniform and ordered, more catalytic active sites and adsorption sites can be reserved, meanwhile, mayenite is prepared to be compounded with a nickel-based catalyst, the carbon deposition resistance of the nickel-based catalyst is improved by use of free oxygen structures, the catalytic performance is enhanced, and efficient degradation of biomass tar is realized. The raw material source is wide, the preparation method is simple and high in applicability, the stability of the biomass gasification process can be substantially improved, the gasification cost can be reduced, and the method has higher economic value and environmental value and is suitable to be promotedand used by manufacturers.

The invention discloses biological carbonaceous filler and a preparation method thereof. The method is characterized by sequentially comprising the following steps of: a, cleaning and airing a biomass solid and processing the biomass solid into granules; b, pyrolyzing the granular biomass solid in anoxic or anaerobic atmosphere at the temperature of between 300 and 700 DEG C for 1 to 3 hours; c, cooling the pyrolyzed substance, and then washing the substance by using acid to remove dust; and d, cleaning the substance by using clear water and drying the substance to obtain the granular biological carbonaceous filler. The invention provides the preparation method for the biological carbonaceous filler with simple process and low cost; and meanwhile, the filler prepared by the method has thecharacteristics of stable property, good film-forming effect, high water treatment effect and no later pollution to the environment.
