摘要
研究了降雨量、气温和风速与甘蓝生长期菜青虫(Pieris rapae)发生量之间的关系,运用模糊数学预测甘蓝生长期田间菜青虫的发生量。经检验,2014年预报与实测相符合,2003~2013年预测符合率达91%。
The relationships between rainfall,air temperature,the wind speed and the occurrence quantity of Pieris rapae in the period of cabbage growing were studied. The occurrence quantity of caterpillar in the period of cabbage growing was forecasted using fuzzy mathematics. Upon examination,2014 forecast was consistent with the measured. Forecast accuracy was91% in previous years.
