title: [Effects of fertilizer application on contents of 2-undecanone and soluble carbonhydrate in Houttuynia cordata with different fertilizers].
abstract: OBJECTIVE
  To investigate the effect of five kinds of fertilizers at three application levels on the content of 2-undecanone and carbohydrate in Houttuynia cordata.
  
  
  METHODS
  A single factor randomized block design was used to investigate the content of 2-undecanone and carbohydrate in the plant.
  
  
  RESULTS
  The results showed that the content of 2-undecanone was the highest both in aerial and underground parts of H. cordata, which was fertilized with complex fertilizers served in conventional way, having the content 18.6 microg g(-1) and 26.0 microg g(-1) respectively. In addition, 2-undecanone contents in aerial parts of H. cordata (14.9 microg g(-1)) fertilized with manure of human were also higher than that with chemical fertilizer, pig and duck manures, but no significant difference were found among the other treatments in aerial or underground parts of the plants, respectively. The results also demonstrated that fertilized with organic fertilizer might be beneficial to enhance the quality of sugar in H. cordata, mainly including the contents of total sugar, solutable sugar, fructose and reduced sugar in the plants, especially with manure of human and pig.
  
  
  CONCLUSIONS
  As the result of this study and the related previous research on yield of H. cordata were considered, the fertilizing ways for increasing quality of H. cordata should take the manure of human as a main fertilizer and mix with the other organic fertilizers, complex fertilizers and chemical ones may be needed to balance the plant nutrient. In the field practice, the amount of organic fertilizer including 108,000 kg hm(-2) human mature, together with some high-efficient complex fertilizer and a small amount of quick-acting chemical fertilizer is recommended.
