摘要
用正交多项式回归对西安和关中地区棉花生育期连阴雨总量进行了预报，历史拟合率在８５％以上，在实际预报中，取得了较好的效果。
The amount of continuous pricipitation was predicted by orthogonal polynomial during the development of cotton in xi’an and Guanzhong. The historical fitting rate is above 85%, and good results were obtained in practical in prediction.
