The invention relates to the technical field of agricultural fertilizers, in particular to a macroelement water-soluble fertilizer for improving soil and a preparation method of the macroelement water-soluble fertilizer. Tripotassium phosphate, monopotassium phosphate, disodium octoborate tetrahydrate, zinc sulfate monohydrate, microelements and a soil conditioner are compounded to obtain the macroelement water-soluble fertilizer capable of promoting plant growth and improving soil quality. The macroelement water-soluble fertilizer also has a soil loosening function; in the soil conditioner A, the porous structure of the coal gangue can provide a relatively stable living environment for the microorganism sporosarcina pasteurii while increasing the total porosity of the soil and playing a synergistic effect with the sporosarcina pasteurii and the polyvinyl alcohol, and a plant growth regulator secreted by the sporosarcina pasteurii is adsorbed and slowly released; leaching of nutrients is avoided; the soil conditioner B effectively exerts the synergistic remediation effect of the calcium conditioner, the sodium alginate and the humic acid on the soil, the slow release time of the humic acid is prolonged, soil hardening is improved, and the soil conditioner has a wide application prospect.

The invention discloses a method for recovering trisodium phosphate, tripotassium phosphate, iron oxide red and graphite from iron phosphate slag, which comprises the following steps: step 1, pulping: putting the iron phosphate slag into pulping equipment, adding a proper amount of deionized water, and starting the equipment for pulping, so that the iron phosphate slag is fully dispersed to form a uniform pasty material; the pulping aims to increase the contact area between the iron phosphate slag and a subsequent reagent and improve the efficiency of a subsequent reaction; step 2, stirring and leaching: transferring a slurry material obtained by pulping into a stirring and leaching reaction kettle, adding 32% of liquid caustic soda into the reaction kettle according to a proportion of 20%, then starting a stirring device, and controlling the temperature in the reaction kettle to be 25-40 DEG C and the stirring and leaching time to be 30-60 minutes, so that the liquid caustic soda fully reacts with components in the iron phosphate slag; the method has the advantages that various valuable components in the iron phosphate slag are efficiently recycled, and the method is high in resource utilization rate, environmentally friendly, low in cost and the like.

A method for producing polyolefin resin foam particles that enables a high foaming ratio and suppresses the formation of excessive foam using talc, and polyolefin resin foam particles containing talc that exhibit a high foaming ratio and suppress the formation of excessive foam are provided. The above manufacturing method involves releasing polyolefin resin particles containing carbon dioxide, which are dispersed in an aqueous medium within a sealed container, from the sealed container under a pressure lower than the pressure inside the container to cause foaming. The polyolefin resin particles contain one or more compounds A selected from the group consisting of magnesium nitrate, tripotassium phosphate, trisodium phosphate, potassium carbonate, and calcium nitrate, and talc. The amounts of talc and compound A added are adjusted within a predetermined range. The polyolefin resin foam particles have an average bubble diameter of 20 μm or more and 200 μm or less, and contain a polyolefin resin, one or more compounds A selected from magnesium nitrate, tripotassium phosphate, trisodium phosphate, potassium carbonate, and calcium nitrate, and talc, and the content of talc and compound A is adjusted to a predetermined range.
