Zusammenfassung:The present disclosure provides a joint control method for nitrogen and phosphorus emissions in farmlands, comprising: reducing nitrogen and phosphorus input during crop sowing or planting by applying composite organic material and chemical fertilizer, wherein the composite organic material comprises: 200-250 parts of edible fungi residues, 300-350 parts of charcoal and 5-10 parts of rhamnolipid; constructing a nitrogen-phosphorus retention layer by utilizing composite microbial agent in combination with 150 parts of edible fungi residues and 20 parts of straw-based hydrogel; constructing a barrier layer by utilizing composite material, and controlling downward leaching of nitrogen and phosphorus that are not absorbed by crops, wherein the composite material of the barrier layer comprises: 25-35 parts of straw-based hydrogel, 20-30 parts of edible fungi residues, 35-55 parts of bentonite and 5-10 parts of corn flour.
