| 摘 要： | 通过改良试验研究，3种措施都改善了草地生境，增加土壤速效养分，增加牧草在草群中所占的比重。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39．9％～19．8％和27．5％～34．4％，使禾本科牧草比重降低21．3％～15.3％，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26．7％～13．4％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27.3％～17．7％、23．2％～36.3％，禾本科牧草比重降低12．1％～10．1％，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: | In this study, the three measures all improved the grassland habitat, increased the soil fast-acting nutrient and forage grass proportion in the grass group.The fertilizing measure had a significant improved effect on leguminosae and composite forage grass, which proportions in the grass group were increased by 39.9%-19.8% and 27.5%-34.4% respectively than the control farm plot, but the gramineae forage grass proportion reduced by 21.3%- 15.3%, the yield of edible forage grass increased by 22.0%-57.8%. The fencing measure made the leguminosae and composite forage grass proportion increased by 26.7%-13.4% and 4.7%-9.0% respectively, the yield of edible forage grass increased by 13.1%-78.0%. The Shallow Ploughing measure made the leguminosae and composite forage grass proportion increased by 27.3%-17.7% and 23.2%-36.3% respectively, but the gramineae forage grass proportion reduced by 12.1%-10.1%, the yield of edible forage grass increased by -28.5%-28.6%. It was clear that the mearures of fertilizing and fencing were effective ways to improve grassland. |
