The active ingredient is any one or a combination of aconitine, colchicine and solanine. The invention uses several alkaloids as active ingredients to prepare biological fertilizers for preventing and treating root-knot nematodes in fruits and vegetables, which has excellent insecticidal effects, is friendly to the environment and crops without any pollution, and has the effect of fertilizers without residues and side effects. Environmental friendliness and sustainable production.

The invention discloses an anionic type photocatalyst which comprises the following components in parts by weight: 80-100 parts of titanium dioxide, 10-30 parts of a catalyst promoter, 0.1-2 parts oftourmaline powder, 0.1-5 parts of ferrocene and 0.5-30 parts of kieselguhr, wherein a metal platinum is adhered to the surface of the titanium dioxide; and the catalyst promoter is platinum-nitrogen codoped titanium dioxide. The anionic type photocatalyst has relatively good photocatalytic activity within a range of visible light and ultraviolet light, is capable of continuously releasing oxygen anions, is capable of effectively decomposing organic compounds such as formaldehyde and benzene with double bonds and is relatively good in catalysis activity. The invention further provides a preparation method of the anionic type photocatalyst.

The invention belongs to the crops plantation field, and specifically relates to a double-cropping rice safety plantation method in a medium-mild pollution farmland; the novel method can solve the technical problems that a conventional technical scheme cannot safely plant the double-cropping rice in a farmland polluted by copper, cadmium, lead, arsenic, and chromium at a medium-mild level; the novel method applies different passivating agents according to soils of different ph conditions; the passivating agent is preferably compounded, paddy rice breed selecting and water fertilizer regulation and control management technology are combined, so the copper, cadmium, lead, arsenic, and chromium content in the planted double-cropping rice can comply with the national foodstuff safety standard GB 2762-2012; the novel method is safe and reliable, and can continuously and effectively plant and produce the double-cropping rice in the copper, cadmium, lead, arsenic, and chromium medium-mild polluted farmland; the method is ecological and environmental protection, economic and effective, low in cost, high in universality, and can be massively promoted in usage.

The invention discloses a preparation method and application of a bifunctional electrocatalyst of a molybdenum disulfide composite material, and belongs to the technical field of electrocatalysts. Thepreparation method comprises the following steps: preparing a precursor ZIF-8@ZIF-67 at first, carrying out carbonization to obtain C-N / Co, then adding C-N / Co, ammonium tetrathiomolybdate and hydrazine hydrate into N,N-dimethylformamide together, preliminarily preparing a molybdenum disulfide composite material through a solvothermal method, and finally, stabilizing molybdenum disulfide compositematerial by heat treatment to obtain a molybdenum disulfide composite material C-N / Co4S3@MoS2. The molybdenum disulfide composite material can be used in hydrogen evolution reactions or oxygen evolution reactions. The molybdenum disulfide composite material has strong conductivity, high atom utilization rate and excellent catalytic performance, and has the advantages of low cost, high efficiency,stability and the like.

The invention relates to the field of architectural decoration, in particular to a method for constructing a bamboo lattice lampshade, which comprises the following steps: sequentially steaming, dipping, and hot-pressing the bamboo chips; The bottom of the steel frame protrudes from the finished surface of the suspended ceiling; draw the projection outline of the bamboo lattice lampshade on the ground according to the construction drawings, select the points on the projection outline to vertically set the line upward, and build scaffolding around the line; install the ring main at the bottom of the steel frame of the ceiling The keel, the vertical main keel is installed on the ring-shaped main keel, the auxiliary keel is pierced on the vertical main keel, and then a number of bamboo pieces are fixed on the outside of the vertical main keel and the auxiliary keel and woven into bamboo weaving. Bamboo lattice and heavy bamboo lampshades use renewable bamboo as raw materials, replacing traditional aluminum, wood and other raw materials. The utilization rate of bamboo is as high as 90%, far exceeding the utilization rate of traditional raw materials. It is not only sustainable production, but also effective protect environment.

The invention discloses a biological sterilizing agent for preventing tomato leaf mold. Amygdalin serves as an active ingredient, the weight percentage of the amygdalin is between 0.1% and 60%, and ethyl alcohol serves as a solvent; other adjuvants or sterilizing active ingredients can further be added in the sterilizing agent. The invention provides new application of the amygdalin, and the biological sterilizing agent can be used for inhibiting and killing leaf mold germs, particularly has a good prevention effect on leaf mold of garden stuff such as tomatoes, is friendly to environment andcrops, does not have any pollution, has no residue or toxic and side effects simultaneously, is environmentally friendly and can be continuously produced.

The invention relates to application of a green activator to preparation of a porous carbon material. The method includes: taking agricultural waste as a carbon precursor, conducting hydrothermal treatment at 250DEG C for 4h, and performing filtering to obtain brown solid residue; dissolving the brown solid residue and potassium formate in a mass ratio of 1:4 in ultrapure water, performing heatingstirring for 4h at 70DEG C, and conducting drying at 120DEG C; taking out the sample, crushing the sample by a agate mortar, in a tubular muffle furnace and under nitrogen protection, conducting hightemperature carbonization at 600-850DEG C and performing activation for 1-4h, and conducting cooling to obtain black solid residue; using 0-80DEG C 10% V / V hydrochloric acid for cleaning, then usingdeionized water for cleaning, and conducting pumping filtration and drying so as to obtain the porous carbon material. Compared with the traditional activators, the activator provided by the inventionis cheap, nontoxic, non-corrosive and environment-friendly, and meets the needs of sustainable development strategy, the requirement for production equipment is simple, and the generated carbon material has certain degree of graphenization, high specific surface area, and wide pore size distribution. In addition, agricultural waste can be used as carbon precursor to achieve high value recycling.
