| 中文摘要: |
| 北京顺义地区玉米田的大仓鼠捕获率(x)与玉米受害率(y)的关系呈显著相关性,其关系式为y=0.088 4x+1.111 5。本文根据目前农业生产水平和农民对灭鼠投资的承受能力,结合大仓鼠捕获率与玉米受害程度关系制定出顺义区玉米田防治大仓鼠的经济阈值。 |
| 英文摘要: |
| A study on the number of the great long-tailed hamster Tscherskia triton and its damage rate to corn in Shunyi of Beijing was conducted.The results showed that the capture rate of the hamster(x) and its damage to corn(y) exhibited a significant correlation,which could be formulized as y=0.088 4x+1.111 5.Taking both of the local situation and the relationship between the capture rate of hamsters and its damage into consideration,an economic threshold could be established. |
