Goodness-of-Fit Test Method for Heat Damage Probability of Rice at Booting Stage in High Temperature and Hot Weather in Zhejiang

In order to avoid or reduce impact of high temperature heat damage on booting stage of rice，a heat damage probability prediction model was established，and the chi-square test method was used to determine its fitness.Results showed that degree of fit between predicted temperature value and actual temperature value was high.The model can effectively predict probability of occurrence of heat damage in rice fields and classify risk level of high temperature heat damage.
