摘要
通过建立平均降雨量、平均气温与沙芥生长期菜蛾发生量之间的模糊矩阵,预测沙芥生长期菜蛾的发生量,验证结果表明:历史符合率达100%,且2005年预报与实际完全吻合。
The emergence amount of Plutella xylostella in the growth period of Pugionium cornutum was predicted with the fuzzy matrix between emergence amount of Plutella xylostella in the growth period of Pugionium cornutum and the average rainfall with average temperature. It was verified the historical coincidence rate reached 100 percent and the prediction in 2005 was totally identical with reality. The method was easy to be used and convenient to be popularized.
