Abstract: A method for simulating a development date based on a response mechanism and an adaptation mechanism of a crop to an environment, including: collecting crop phenology data observed at a research station; obtaining a day of year of a start date, a quantity of days, and an average temperature, in the development phase, based on the crop phenology data; obtaining a development rate based on the quantity of days in the development phase, where the development rate is a reciprocal of the quantity of days in the development phase; calculating a product of the average temperature and the day of year of the start date of the development phase; and obtaining a regression equation as an equation simulating the development date, through a linear regression algorithm, where the development rate serves as a dependent variable, and the average temperature and the product serve as regressors.
