Soil conditioner capable of preventing water and soil loss

The invention discloses a soil conditioner capable of preventing water and soil loss. The soil conditioner is prepared from the following raw materials in parts by weight: 17-20 parts of ferric citrate, 4.5-6 parts of potassium chloride, 10-15 parts of nano waterborne adhesive, 0.002-1 part of polyethylene glycol acrylate, 30-50 parts of anionic polyacrylamide, 10-18 parts of monopotassium phosphate, 10-20 parts of shell powder, 10-20 parts of crab shell powder, 10-20 parts of oyster shell powder, 20-40 parts of culture pond silt, 15-20 parts of bamboo powder, 5-10 parts of ferric sodium ethylene diamine tetraacetate, 10-20 parts of sugar alcohol magnesium, 0.8-1.8 parts of 1-10 billion silicate bacteria per gram and 45-65 parts of old brine. By adopting the soil conditioner disclosed by the invention, the effect of preventing water and soil loss is good, the loss rate of the dissolved fertilizer elements is remarkably reduced, the organic content of the soil can be increased, and the anions and cations can b
