The invention discloses a semi-solid-state complex no-tillage dry direct seeding method for crop seeds. The no-tillage dry direct seeding method comprises the following steps: S1, keeping a water layer of 1cm-5cm in a ditch, and paving straws obtained by harvesting preceding crops on a ditch surface; S2, applying a base fertilizer on the ditch surface paved with the straws and cleaning the ditch; S3, seeding the crop seeds on the ditch surface, and mixing the crop seeds with semi-solid-state biomass materials, a compound fertilizer and a biopesticide before seeding before seeding seeds, wherein the mixing mass ratio is that the crop seeds to the semi-solid-state biomass materials to the biopesticide is (1-10) to (70-800) to (1-3), and the moisture content of the semi-solid-state biomass materials is 40%-80%; and S4, after seeding the seeds, keeping the ditch surface at a dry state for 3-7 days. According to the semi-solid-state complex no-tillage dry direct seeding method, tillage and combustion of winter crop straws are not carried out, a whole land of field immersing water is not used for irrigation and the water immerses after the seeding, and the biological benefits are obvious; the working energy consumption is reduced, stubbles are not killed by pesticides, haze is reduced and the irrigation water is reduced.

The invention discloses an auxiliary open fire heating device for improving the surface quality of extruded plastics. The auxiliary open fire heating device comprises a bracket base device and a fire jetting combustion furnace tray device and is characterized in that the bracket base device comprises a base and a support frame, and the support frame is mounted on the base; the fire jetting combustion furnace tray device comprises a gas inlet valve, a gas guide pipe and nozzle devices; the gas inlet valve is mounted at an inlet of the gas guide pipe; the nozzle devices are mounted on the gas guide pipe; and the fire jetting combustion furnace tray device is mounted on the bracket base device through the support frame. The auxiliary open fire heating device has the advantages of simplicity, convenience and feasibility and also has the advantages of being convenient to use, high in efficiency, high in practicability, light in structure and convenient to mount, disassemble and operate. Generally, when large-molecular-weight plastics of a molecular chain net structure, such as organosilane crosslinked polyethylene, are processed and produced, the auxiliary open fire heating device is directly mounted on a nose of the existing extruder by using magnetic absorption and utilizes open fire to carry out auxiliary open fire heating on a forming die orifice and an extruded wire so as to improve the poor surface quality of the extruded product.

The invention discloses a comburent for microwave treatment of waste gas and a combustion method and combustion device thereof. The comburent is prepared from water, a wave absorbing substance, firstsupporting particles, second supporting particles and an aqueous binder. The combustion device comprises a shell, a microwave unit and a flange. The comburent and the combustion method and combustiondevice thereof have the advantages that the comburent which is prepared from the water, the wave-absorbing substance, the first supporting particles, the second supporting particles and the aqueous binder is adopted to absorb microwaves, with the cooperation of the combustion method and the combustion device, a heat source is provided for the waste gas treatment process in a mode of converting microwave energy into heat energy inside the comburent, so that the heat transfer rate is higher, the heating speed is high, the heat loss is small, the operation is convenient, no sharp corner exists inthe shell of the combustion device, with the cooperation of a ventilation reflection plate and the conical flange, the microwaves are reflected into the shell to uniformly act on the comburent, so that the energy loss is reduced, the heat conversion rate of the comburent is increased, and an outer thermal insulation plate, a wave absorption coating and an inner thermal insulation plate are arranged, so that the safety of combustion treatment of the waste gas is improved.
