摘要: The aim of this study was to investigate the use of a remote-sensing model to compute a hybrid rotation period of multi-crop rotation in large area. The model was constructed to compute the hybrid rotation period of cotton-rice and cotton-others of 38 towns in XingHua City, Jiangsu Province, China. The rotation periods for cotton-rice and cotton-others were computed as 2.09 and 3.38 years using the data from satellite remote sensing images. The results were shown to lead to a hybrid rotation period of cotton-rice and cotton-others of 1.24 years. This indicates that there is a possibility of managing multi-crop rotation in large area from hybrid rotation periods and suggests that it is possible to measure crop growth status in large area with hybrid rotation periods to make management decision for crop diseases.
