| 摘 要： | 施肥改良使豆科和菊科牧草在草群中比重分别比对照区增加19.8%~39.9%和27.5%~34.4%,使禾本科牧草比重降低15.3%~21.3%,可食牧草产量增加22.0%~57.8%。围栏封育使豆科和菊科牧草分别增加13.4%~26.7%和4.7%~9.0%,可食牧草产量增加13.1%~78.0%。浅耕翻使豆科和菊科牧草比重分别增加17.7%~27.3%、23.2%~36.3%,禾本科牧草比重降低10.1%~12.1%,可食牧草产量增加-28.5%~28.6%。由此得出,施肥和围栏封育是草地改良的有效途径。 |

| Abstract: | The ratio of leguminosae and compositae forage in the grass biocenose increased 19.8% -39.9% and 27.5% -34.4% than those in control area, respectively,of gramineae forage decreased 15.3% -21.3% than that in control area and the yield of eatable forage increased 22.0% - 57.8% by means of fertilizing improvement. The one of leguminosac and compositae forage increased 13.4% - 26.7% and 4.7% - 9.0% ,respectively,the yield of eatable forage increased 13.1% - 26.3% by means of closed fencing.The one of leguminosae and compositae forage increased 17.7% - 27.3% and 23.2% - 36.3% respectively, of gramineal forage decreased 10.1% - 12.1%, the yield of eatable forage increased - 28.5% -28.6% by means of shallow ploughing. Those indicated that fertilizing and closed fencing were a effectire way of grassland improve ment. |
