The invention relates to a carbon-based fertilizer potentiating agent and application of the carbon-based fertilizer potentiating agent. The carbon-based fertilizer potentiating agent is characterized by comprising the raw materials in proportion by weight: 50-70 carbon powder, 5-15 humic acid, 2-5 inhibitors mixing urease inhibitor with nitrification inhibitor, 10-20 microelement fertilizer, and 5-10 acid bentonite or clay; biomass granule carbon is selected as a matrix carrier, the production process is simple, raw materials are easily obtained, and the cost is low. The biomass carbon has strong adsorbability, water retention property and light absorption warming property, and can be used as good ammonia stabilizer and soil conditioner except for the carrier. After being applied into soil, the potentiating agent can lead the fertilizer to slowly release, and can relieve the influence of drought and lacked water and low temperature on crop growth. The potentiating agent not only can improve the fertilizer utilization rate, but also is environment-friendly and safe, can effectively improve the utilization rate of nitrogenous fertilizer and phosphate fertilizer, reduce fertilizer loss, and simultaneously can lighten the water body pollution and greenhouse effect by nitrogenous fertilizer, reduce the content of nitrate nitrogen in agricultural products, and ensure the safety production of food.

The invention relates to a crop seed coating agent prepared from novel biomass carbon of agricultural wastes. The crop seed coating agent is characterized by comprising the following components by weight percent: 2.5-12.5% of biomass carbon, 20-60% of a filler, 0.5-1.5% of a binder, and 0.1-1% of a dispersing agent, wherein the binder is 0.5-2% aqueous solution of sodium alginate; the dispersing agent is 0.1-2% ethylene glycol aqueous solution; and the filler is bentonite. The method comprises the steps of pouring the seed into a coating device, spraying the binder and the dispersing agent to wet the seed surface; adding 1 / 4 to 1 / 5 of filler to be evenly attached to the seed surface, and repeating for 3-4 times until the enveloping layer is 0.4-0.6mm; adding a mixture of the biomass carbon and residual filler, and rocking the container, so that the enveloped material is evenly adhered to the seed surface, and drying in the shade at a well ventilated place. A pesticide ingredient is not added to the seed coating agent; and the seed coating agent has the same human and animal safety, germination rate, germinative force and growth situation of the crop as a common coating agent, and has significant economic and environmental benefits.

The invention relates to a biomass spiral pyrolytic process and an antipyretic device. In the invention, the spiral pyrolytic process is adopted to pyrolyze biomass materials in a pyrolysis reactor, the materials are added from the upper part of the pyrolysis reactor, high temperature flue gas enters a flue gas separation chamber for shunting from the lower part of the pyrolysis reactor, the direction for the biomass materials to enter the pyrolysis reactor is opposite to the direction for the flue gas to enter the flue gas separation chamber, the high temperature flue gas is used for providing heat for pyrolysis, and the biomass materials are pyrolyzed to obtain biomass and fuels. The antipyretic device, namely the pyrolysis reactor comprises an outer cylinder, an inner cylinder, a heat insulation system and a spiral propeller. Materials slowly enter a pyrolyzer by way of the spiral propeller from an upper feed port, and the biomass is pyrolyzed by the high temperature flue gas at the bottom via the flue gas separation chamber from bottom to top. The biomass spiral pyrolytic process in the invention has the advantages that the flue gas residual heat resources can be effectively used, biomass carbon and fuels can be prepared, the method is simple and feasible, the heat transfer effect is good and the popularization and application values are excellent.
