摘要: 为评价落盘式测定法在产草量估测中的应用效果,利用落盘式测产仪对封育亚高山草甸产草量进行估测试验.分析草层压缩高度与鲜草产量之间的相关性,建立并验证草地产草量的估测模型。结果表明,草层压缩高度与鲜草产量之间存在显著的线性关系,草地产草量的估测值与实测值之间显著相关。落盘式测定法能够对试验区封育亚高山产草量进行准确、快速的估测。

Abstract: A kind of falling-plate meter made in New Zealand was used to estimate the pasture yield of an enclosed subalpine meadow. The relationship between compressed sward height and pasture yields was analyzed and the estimation model was established. The results showed that there were close correlation relationships between compressed sward height and pasture yield, and the estimated value of pasture yields were significantly related with the measured value. It was indicated that the device of the falling-plate meter could be used to estimate the pasture yield in enclosed subalpine meadow with high efficiency.
