Abstract: Via high-throughput sequencing analysis technology, bamboo charcoal was used as an addictive to investigate its effects on the loss of nitrogen and phosphorus and microbial community structures in greenhouse vegetable soil. It was shown that, compared with control, the yield of vegetable was significantly (P<0.05) increased by 21.5% with bamboo charcoal addition, and the average concentration of total nitrogen (TN) in surface water was decreased by 5.5%, and the average concentration of total phosphorus (TP) in surface water was significantly (P<0.05) decreased by 48.3%. The results of Chao, ACE, Shannon and Simpson index showed that the bamboo charcoal addition increased soil microbial diversity and promoted the enrichment of dominant bacteria species, yet not significantly.

Key words: biochar, nitrogen and phosphorus loss, protected cultivation, soil microbes
