The invention belongs to the technical field of radioactive decontamination and discloses a preparation method of a corrosive self-embrittled type radioactive decontaminant used on the surface of an iron-based material. The preparation method comprises the following steps: by taking silica as an inorganic component, modifying the silica by using a silane coupling agent KH550; by taking a ternary random copolymer of methyl methacrylate, methacrylic acid and trifluoroethyl methacrylate as an organic component, carrying out organic / inorganic compounding preparation so as to obtain a compounded self-embrittled type decontaminant; further compounding the decontaminant with corrosive components such as nitric acid, so as to obtain the corrosive self-embrittled type radioactive decontaminant for carbon steel and stainless steel. The decontaminant prepared by using the method aims at strong-stationarity radioactive contaminants on the surface of the iron-based material, an iron-based metallic surface layer is damaged through the corrosive component, and the contaminants are adsorbed and wrapped by the decontaminant and are dried and embrittled to form brittle sheets which are peeled off by self, so that removal of radioactive contaminants on the iron-based metallic surface is achieved.

The invention discloses dedicated fruit tree set fertilizer which is prepared from the following raw materials in parts by weight: 34 to 36 parts of soybean meal, 15 to 18 parts of needle mushroom dreg, 20 to 24 parts of monosodium glutamate residue, 3 to 4 parts of potassium pyrophosphate, 4 to 6 parts of ammonium bicarbonate, 1 to 2 parts of sodium polyphosphate, 2 to 3 parts of sodium silicate, 10 to 14 parts of chitosan, 0.3 to 0.5 part of potassium permanganate, 1.5 to 1.8 parts of manganese sulfate, 1 to 2 parts of acrylamide, 0.3 to 0.4 part of N,N'-methylene bisacrylamide, 2 to 3 parts of ammonium persulfate, 1 to 2 parts of zinc acetate, 0.2 to 0.4 part of yttrium nitrate, a defined amount of absolute ethyl alcohol and a defined amount of water. According to the fertilizer disclosed by the invention, organic components and inorganic components are reasonably matched; thus, the fertilizer has comprehensive nutrient elements and is easy to decompose and absorb; meanwhile, a release characteristic of a coating material of the fertilizer aims at different growth stages of a fruit tree germination stage, a growth period and a fruit swelling period; counterpart supplying of the total nutrient amount is achieved, fertilizer consumption is reduced, nutrient utilization rate is improved at the same time, a fertilizing process is simplified, and economic benefit of planting fruit trees is improved.
