The invention discloses a manufacturing technique of an agricultural cultivation pig bed. The technique concretely includes the following steps: raw materials are weighed according to amounts by weight, the raw materials including straw, rice husks, sawn wood, leaves, rice bran, peanut shells, wood chips, bacterial strains and beneficial microbes, the raw materials are mixed and laid in a flattened manner to obtain a bottom layer, a leaf layer, a first fermentation layer and a second fermentation layer, pig urine and manure are directly discharged on the fermentation bed, pig urine and manure and the padding materials are mixed thoroughly on the basis of digging habits of pigs and auxiliary artificial plowing and harrowing, and through fermentation of the bacterial strain and the beneficial microbes, organic matters of the pig urine and manure are fully decomposed and converted. Pig manure is discharged and fermented anytime, so zero discharge of pollutant is realized. Pig feed is saved, energy and labor force are saved, and benefits are quite obvious. The resistibility of live pigs is improved, and epidemic diseases are less likely to occur. The growing speed of pigs is increased, the production period is shortened, the breeding cost is saved, and the feed digestion utilization rate is increased.
