Study on the Effect of Three Species of Bacteria Fertilizer on Cold Resistance of Turfgrass

  • Received Date: 2003-12-15
  • Three bacteria fertilizer (E,F,H),chemical tertilizer and the compound of bacteria fertilizer and chemical fertilizer were separately applied on Poa pratensis to inspect their effects to the growth and the cold resistance of turfgrass.The results indicated that bacteria fertilizer and the compound of bacteria fertilizer and chemical fertilizer could both improve cold resistance of turfgrass greatly.The applying of each kind of three fertilizers induced a different degree of positive effect.The effect induced by bacteria fertilizer was better than that of chemical fertilizer and the effect induced by bacteria F and H was better than that of bacteria E.Applying both bacteria fertilizer and chemical fertilizer showed a better effect on general cold resistance than that of applying bacteria fertilizer or chemical fertilizer solely.Study on applying bacteria fertilizer and chemical fertilizer showed a concurrence of the complementarity effect and the unreplacement effect to different indexes on cold resistance enhancement.The applying of both bacteria fertilizer and chemical fertilizer revealed a certain extent of incomplete adding status.The details included:The difference of electrolyte leakage of turfgrass was unsignificance between treating with bacteria fertilizer and treating with chemical fertilizer.But a better growing of taproot and a more contents of soluble sugar was showed in treating with bacteria fertilizer than treating with chemical fertilizer.The activity of peroxidase(POD),the contents of chlorophyll,and amount of fibre of turfgrass were higher in treat bacteria F and H than that of treating with chemical fertilizer,but the effect of treating with bacteria F and H was poor than that of treating with the mixture of bacteria fertilizer and chemical fertilizer.

Abstract: Three bacteria fertilizer (E,F,H),chemical tertilizer and the compound of bacteria fertilizer and chemical fertilizer were separately applied on Poa pratensis to inspect their effects to the growth and the cold resistance of turfgrass.The results indicated that bacteria fertilizer and the compound of bacteria fertilizer and chemical fertilizer could both improve cold resistance of turfgrass greatly.The applying of each kind of three fertilizers induced a different degree of positive effect.The effect induced by bacteria fertilizer was better than that of chemical fertilizer and the effect induced by bacteria F and H was better than that of bacteria E.Applying both bacteria fertilizer and chemical fertilizer showed a better effect on general cold resistance than that of applying bacteria fertilizer or chemical fertilizer solely.Study on applying bacteria fertilizer and chemical fertilizer showed a concurrence of the complementarity effect and the unreplacement effect to different indexes on cold resistance enhancement.The applying of both bacteria fertilizer and chemical fertilizer revealed a certain extent of incomplete adding status.The details included:The difference of electrolyte leakage of turfgrass was unsignificance between treating with bacteria fertilizer and treating with chemical fertilizer.But a better growing of taproot and a more contents of soluble sugar was showed in treating with bacteria fertilizer than treating with chemical fertilizer.The activity of peroxidase(POD),the contents of chlorophyll,and amount of fibre of turfgrass were higher in treat bacteria F and H than that of treating with chemical fertilizer,but the effect of treating with bacteria F and H was poor than that of treating with the mixture of bacteria fertilizer and chemical fertilizer.
