In the process of yield prediction, it mainly includes the prediction of crop yield and quality, the prediction of local crop annual yield and the prediction of crop phenological period. When forecasting crop yield and quality, farmers should pay attention to crop quality issues in the critical period of prediction, make relevant preparations in advance, and ensure that crop quality meets the standards. In the forecasting of crop years, farmers can analyze the most suitable crop harvest period according to the agricultural weather forecast and make corresponding preparations before harvest. When predicting crop phenological period, farmers should understand the development of crops according to the problems existing in agrometeorological forecast, so as to maximize the growth potential of crops.
