Abstract:
Shufu county in Kashgar，Cusack salinized soil was used as materials by in-situ method，different nitrogen deposition effects on soil nitrogen mineralization was studied.The results showed that the settlement of nitrogen amount reached 1.0 g?m-2?a-1 was the best threshold value of soil ammonium nitrogen content；N of ammonification rate of 0.5 g?m-2?a-1 was the best threshold value of soil ammonifying rate；the settlement of nitrogen amount reached 3 g?m-2?a-1 was the best threshold value of soil nitrification and mineralization.Salinization of soil ammonium nitrogen content and soil nitrogen ammonification rate was in reach maximum 20-40 cm soil layer，and nitrate content，nitrification rate and mineral nitrogen content，mineralization rate were all in the surface layer reach maximum (0-20 cm)，it indicated that the soil surface (0-20 cm) mineralization and nitrification faster.
