【 摘 要 】

The object of this study was to investigate the effect of the long-term application fertilizer on soil total sulphur and valid sulphur. The results showed that applying fertilizer can improve total sulphur and valid sulphur. In comparison with the low level of nitrogen fertilization treatment, the high one total sulphur and valid sulphur were obviously increased by 29.41% and 19.0%, respectively. Compared with in application of different levels nitrogen and the low level of organic fertilizer, the high level treatment total sulphur and valid sulphur contents were significantly increased by 10.73% and 23.47% than the low one. In application of organic fertilization can also improve total sulphur and valid sulphur The total sulphur and valid sulphur content were higher than organic fertilization only treatment 34.14% and 455.89% in comparison with high levels of organic fertilization mix with nitrogen, phosphorous and potassium fertilization treatment.
