| 摘 要： | 通过对化州市稻瘿蚊16 a历史资料的研究分析,明确了决定稻瘿蚊发生程度的关键因素是降水量和平均气温。由此以“九.五”研究的有关结论为基础,建立了稻瘿蚊发生程度预测模型:Y=23.4000 0.0054x1-0.7972x2,回报历史拟合率为91.9%,对1999-2005年7 a预测准确率达87.1%。

| Abstract: | Based on the data collected during the year from 1983 to 1999,the precipitation and average temperature were found to be the 2 key factors affecting Orseolia oryzae occurrence on late maturing rice varieties.The forecast model may be expressed as Y=23.4000 0.0054x_1-0.7972x_2.The qualified rates of fitting and prediction using this model amount to 91.9% and 87.1%,respectively. |
