title: [Effects of different cropping system and fertilization on functional diversity in soil microbial community of Chrysanthemum morifolium].
abstract: OBJECTIVE
  To study the effects of Chrysanthemum morifolium based on functional diversity in soil microbial community with different cropping system and fertilization and offer scientific basis for the establishment of the reasonable planting patterns.
  
  
  METHODS
  Combined yield and quality of Ch. morifolium, 8 treatments of different cropping system and fertilization on functional diversity in soil microbial community of Ch. morifolium were investigated by the Biolog.
  
  
  RESULTS
  The AWCD of Ch. morifolium paddy-dryland rotation was higher than that of the continuous cropping, the AWCD of organic fertilizer and compound NPK > single organic fertilizer > single compound NPK > no fertilizer. The principal component analysis about Ch. morifolium soil microbial carbon source use showed that the contribution rate of principal component 1 was 45.5% and principal component 2 was 12.1%, which could explain most information about the variation. Different cropping system of Ch. morfolium differentiated in principal component 1 axis, different fertilization differentiated in principal component 2 axis. The yield of Ch. morifolium and volatile oil content paddy-dryland rotation was significantly higher than that of continuous cropping.
  
  
  CONCLUSIONS
  The Ch. morifolium should be cultivated with organic fertilizer and compound NPK by paddy-dryland rotation patters.
