Abstract: Abstract: In the typical Soil-gravel Area in pingshan County, Hebei Province, it has thin layer and poor soil water-retention capacity and difficulties in irrigation for gneiss and granite mountain soil. Seriously lack of water and fertilizer is the vegetation recover restrictive factor of this area. Comparing with fertilizers，three new fertilizers (bio-organic fertilizer, slow-release fertilizer, microbial agents) were superior to chemical fertilizers on the improvement of soil chemical properties, can significantly increased soil total nitrogen, total potassium, organic matter, nitrogen, available potassium content. With the treatment of bio-organic fertilizer 2000g/socket, soil total phosphorus, total potassium, organic matter, nitrogen and available phosphorus increased by 444%, 87%, 906%, 355%, 1131% than CK, the nutritions of soil have been improved greatly. So, bio-organic fertilizer can be utilized to improve the nutritions, which promote plants to grow and accelerate plants to renew.
