The mango flowering date prediction model based on meteorological factors with high correlation is Y=69 .755-3. 777X ;the prediction model for flowering period length is Y=67. 644-2. 085X ，and both prediction models have an average accuracy rate of over 95. 00% inbacktestingTwomodelswereusedtopredictthefloweringdteanddurationofmangosin25，withanacuracyratenotlowerthan 90.00% ，which can effectively predict the flowering period of Wangmo mango.
