    A Nondestructive Method for Measuring Herbage Mass in Steppe

      摘要
    • 摘要: 采用落盘式测草盘在休闲草地、轮牧草地和连续放牧草地进行了测产试验.结果表明,在天然草地中使用非破坏性的落盘式测草仪测定牧草产量是可行的,牧草压缩高度和牧草产量具有良好的回归关系(r2=0.64～0.90),平均每1 cm压缩高度相当于69～250 kg/hm2的牧草产量.

       

      Abstract: Herbage mass is a function of sward height and density.A rise-plate meter was used as a nondestructive method to measure herbage mass in steppe by rotational grazing,continuous grazing or without grazing.The results showed that the rise-plate meter could be used to measure the herbage mass in natural steppe,because there were good regressive relation between the herbage mass and the compressed sward high(r2 is 0.63-0.90) under different utilization of the pasture.One centimeter of compressed sward height related about 69-252 kg/hm2 of herbage mass.
