Zusammenfassung:The invention belongs to the technical field of wheat cultivation, and particularly relates to a basic seedling accurate calculation method in wheat super-high-yield cultivation. The method comprises the following steps: taking an average temperature value of a weather station from October to January of the next year as initial calculation data; substituting the average temperature value of the ten days of each month into a day-by-day simulation average temperature value calculation formula to obtain the temperature value of each day in the first ten days; substituting the obtained data into a formula for calculating the day-by-day effective accumulated temperature value of the wheat before winter, and calculating the day-by-day effective accumulated temperature value of the wheat before winter; obtaining basic seedlings of the wheat on the basis of various biological characteristics of the wheat in combination with an empirical derivation formula; further calculating the basic wheat seedlings accurately, the
