| 摘 要： | 通过对麦棉套作移栽、春棉直播和夏播棉三类棉田棉株生长的观测，利用生理时间建立了中等水肥条件下棉株的株高、果枝、现蕾、开花、吐絮、脱落等参数的预测模型。利用该模型系统可根据有效积温预测不同种植方式下棉株的生育动态，有助于指导棉花栽培和害虫治理。

| Abstract: | In North China the major planting types of cotton are cotton wheat intercropping,spring cotton and summer cotton. Through three years' investigations from 1989 - 1991,the prediction models of cotton growth and development for different planting types of cotton were established based on the physiological day (PD ), which were more useful for cultivating management of cotton and IPM in cotton field. |
