The invention relates to a method for preparing a soil remediation fertilizer based on lumbrukinase-attapulgite. The method comprises the following steps: weighing attapulgite raw ore, drying and grinding into powder of 120-200 meshes, and adding into distilled water for soaking; weighing a sodium hexametaphosphate dispersing agent to be added into an aqueous solution of the attapulgite powder, wherein the mass of the sodium hexametaphosphate is 1-4% of the mass of the attapulgite; stirring and filtering to obtain a wet filter cake; adding the wet filter cake into a lumbrukinase extracting solution, stirring the mixed solution, and performing vacuum freeze drying; and finally, grinding and granulating, thereby obtaining the lumbrukinase-attapulgite soil remediation fertilizer. According tothe combination of the attapulgite and lumbrukinase, the utilization efficiency of the lumbrukinase soil remediation fertilizer can be greatly improved, inorganic or organic pollution of the soil isremediated, damage of the chemical fertilizer to the soil is alleviated, the soil environment for crop growth is improved, fertilizer and water retaining can be realized, beneficial trace elements areprovided for growth and development of crops, and the fertilizer is a green, safe and environmental-friendly soil remediation fertilizer.

The invention discloses a preparation method of a foliar fertilizer rich in selenium and amino acid. The preparation method comprises the steps of 1, preparing compound probiotics; 2, weighing the compound probiotics, cooked fish paste, urea, potassium sulfate, molasses and sodium selenite according to a preset proportion, then adding the raw materials together, and uniformly stirring to obtain a mixed material; and 3, at the temperature higher than 10 DEG C, enabling the mixed material to be subjected to facultative fermentation, and taking a fermentation product as the leaf fertilizer. The foliar fertilizer prepared by the method disclosed by the invention is used for crop planting, and can promote selenium absorption of crops, increase the selenium content in crop bodies, promote crop growth and increase crop yield.

The invention discloses a biological organic fertilizer and production equipment of the biological organic fertilizer. The biological organic fertilizer comprises the following components in parts byweight: 40-50 parts of crop straws, 15-20 parts of biological enzyme, 40-50 parts of plant stems and leaves, 40-50 parts of plant ash, 15-20 parts of a humic agent, 6-10 parts of ammonium sulfate and6-10 parts of potassium sulfate. The humic agent is prepared from the following material components in parts by weight: 3-4 parts of aspergillus niger, 2.5-3 parts of trichoderma viride, 1.2-2 parts of trichoderma pseudokoningii, 0.8-1 part of cytophaga fermentans, 2.5-3 parts of bacillus amyloliquefaciens, 1.3-2 parts of succinic acid filamentous bacillus and 8-10 parts of chitosan. The biological organic fertilizer has the advantages that the raw materials are accessible, wastes are changed into valuable substances, the problem of environmental pollution is solved, and the fertilizer has theeffects of improving soil, enhancing fertilizer efficiency, regulating crop growth, enhancing crop stress resistance, improving crop quality and the like.

The invention relates to a reversible conversion method of soil infiltration-permeation resistance, which belongs to the field of agricultural soil engineering, and comprises the following steps: firstly, obtaining artificial water-repellent soil by using a water repellent agent; and then a water vapor injection and drainage device and a soil heating device are sequentially fixed on the surface of the cultivated soil according to requirements and are simultaneously covered by water-repellent soil, and the surface of the water-repellent soil is suitable to exceed the highest position of the device by at least 2cm. When infiltration needs to be promoted, water is injected into the water-repellent soil through the water and gas injection and drainage device until water seeps out of the surface layer of the water-repellent soil. At the moment, the water repellency of the water repellency soil disappears, external water can smoothly infiltrate into the cultivated soil, and the water required by crop growth and the like is met; when evaporation prevention is needed, the water vapor injection and drainage device pumps water and starts the soil heating device at the same time, so that water in the water-repellent soil is rapidly reduced. At the moment, the water repellency of the water-repellent soil is recovered, and water loss of the cultivated soil is avoided. The process can be repeatedly realized, and the method is reversible in conversion, free of replacement, long in service cycle and capable of being applied to the fields of agricultural production, water and soil conservation and the like.

The invention provides a heavy metal cadmium composite foliar resistance control agent which comprises the following components in percentage by mass: 10%-15% of soluble silicon, 5%-10% of glycerol, 1%-2% of surfactant, 0.5%-1% of thickener and 72%-83.5% of distilled water, and the principles of silicon and glycerol for inhibiting rice grains from enriching heavy metal cadmium are combined, so that the cadmium reduction effect is more outstanding and more stable; meanwhile, crop growth can be promoted, safe production of heavy metal cadmium polluted farmlands is achieved, grain production safety is improved, the preparation method and the use method of the fertilizer are convenient, and the problems that in the prior art, the production process is complex, cost is high, and generalizability is poor are solved.
