Apple yield prediction method based on meteorological main control factors

The invention discloses an apple yield prediction method based on a meteorological main control factor, and particularly relates to the technical field of fruit tree yield prediction. Apple base county per unit yield data are utilized, and base county apple trend yield is fitted through four methods of three-year moving average, two-year moving average, five-year moving average and quadratic polynomial fitting of per unit yield; the meteorological yield is separated from the per unit yield of the apples; secondly, taking the meteorological yield as a research object; a grey correlation analysis method is used for analyzing the correlation degree of 88 climate factors such as total solar radiation, evaporation capacity of an evaporation pan, accumulated temperature, precipitation, wind speed, highest temperature, lowest temperature, average temperature, high-temperature heat damage days, frost days in a flowering period, low-temperature freezing damage days in a dormancy period in winter ...
