| Abstract: | Based on observation data of xerothermic wind disaster of spring wheat for 20 years and statistical data of yields for 50 years, and combined with historic disaster records for 50 years in Ningxia, a series of xerothermic wind indices of spring wheat was determined by using the method of clustering analysis sieving step by step and yield segregated step by step in the irrigated areas of Ningxia. The Results would have provided a basis for estimating yield losses of spring wheat suffered from xerothermic wind disaster. |
