| 摘 要： | 在云南亚热带人工刈割草地上,选用落盘式测产仪对草地产草量进行测产试验。分析草层压缩高度与鲜草产量、干物质产量之间的相关性,建立并验证草地产量的估测模型。结果表明,草层压缩高度与鲜草产量、干物质产量之间均存在显著的线性关系,草产量估测值与实测值之间显著相关。利用落盘式测产仪能够对云南亚热带人工刈割草地草产量进行快速而准确的估测。

| Abstract: | The rising-plate meter （made in New Zealand）was used to measure the yield of sowed mixed pas-ture in subtropical area of Yunnan Province in 2013.And the correlation relationship between the yield and com-pressed sward height was analyzed.Results showed that there were significant linear correlation relationships between fresh yield,dry matter yield and compressed sward height,and the estimated yield was significantly cor-related with the measured value. |

| Keywords: | rising-plate meter compressed sward height yield estimation model |
