摘要
对家庭牧场的试验研究结果表明:(1)禾本科牧草在不同的处理区中的高度和盖度最大,豆科牧草在不同处理区中的密度最大;(2)禾本科牧草在不同的处理区中的重要值最高,豆科牧草最低;(3)在不同处理区中的土壤都是以砂粒的比重最大;(4)高平原草地氮素、磷素、钾素的潜在供应能力最高,低湿地草地速磷和速钾的实际供应能力最高;土壤肥力高平原草地最高,低湿地草地次之,沙质草地最低。
A family rangeland was studied. The results showed that ：（1） gramineous forage species were highest in height and cover in different treatment areas, while leguminous species had the highest density; （2） gramineous species had the highest importance value, while legumes the lowest; （3）sands in soil had the highest proportion in different treatment areas compared to clay and silt; （4） high plain grass land supplied the most potential N, P and K, lower wetland grassland supplied the most available P and K. Soil fertility was in the order： high plain grassland〉lower wetland grassland〉sandy grassland.
