Abstract: After 14 and half years long-termfixed fertilization trial with vegetables , the amount and quality of soil organic matter changed evidently. Soil fertility was highly improved by 10 - 15 yearspuse of organic manure in the view of organic matter accumulation and quality improvement . The soil organic matter in the combination of organic manure and inorganic nitrogen was higher than that in organic manure only , while in the trial with only inorganic nitrogen the organic matter decreased. The organic matter content in the control plot fluctuated around 19.0 g·kg -1 . The accumulation rate of organic matter in open area was quicker than that in protected field , but for the CKwas not the case. The yearly mineralization rate of organic matter was between 7.0 % - 11.1 %. The average mineralization rate for open area was 8.67 % , while for protected condition was 9.54 %. Phosphorous and potassium could increase organic matter content to some extent , but it must be based on application of organic manure.With the extension of fertilization with organic , especially with the combination with organic and inorganic fertilizer,the soil readily oxidizable organic matter increased, while Kos decreased ; The soil active humus content, humus acid and E4/ E6 value were increased , while molecular weight and aromaticity of humus acid were decreased , thus progress to humus formation and quality of organic matter were enhanced.
