| Abstract/Contents: | "This study applied 7 kinds of slow release nitrogen fertilizers (MU, IBDU, SUD1, SUD2, SUDT2, lignin fertilizer, and organic fertilizer) and one kind of fast release fertilizer (Urea) on turf in autumn. The cold resistance of bluegrass (Poa pratensis L.) was studied by measuring the contents of catalase (CAT), soluble protein (SP), water sloluble [soluble] sugar (WSS), proline (Pro) and malonaldehyde (MDA) in different stages during winter. Result indicated that the application of nitrogen in autumn could increase the cold resistance of turfgrass compared with control. The cold resistance of 7 slow released nitrogen fertilizers was more effective than Urea and they did increase the activity of SOD, the contents of Pro, SP and WSS, but reduced the content of MDA. The effect of MU and IDBU on MDA activity was significantly lower (P<0.05) than control. The effect of organic fertilizer on CAT, Pro and SP was also lower (P<0.05) than control, and its effect on MAD and WSS was similar with slow release fertilizers. Results indicate that it was also an effective way to apply organic fertilizer in autumn to improve cold resistance. Based on the cold-resistance value calculated by the Fuzzy method, cold-resistance of bluegrass was ranked as SUDT2>SUD2>IBDU>lignin fertilizer>SUD1>MU>Organic fertilizer>Urea. All fertilizers could be divided into 3 groups according to cold-resistance improvement, SUD2 and SUDT2 as high group, organic fertilizer and MU as low group." |
