Abstract:

Crop yield estimation is related to many aspects, such as grain scheduling, grain market price balance, agricultural structure adjustment and so on. Therefore, combined with multiple regression analysis, this paper constructed a crop yield estimation model. In this model, the author used gray correlation analysis to find the leading factors that affect crop yield, and then used the data of the leading factors as the input to construct the multiple linear regression estimation model of crop yield and get the estimated value of crop yield. The results show that: by using this model to estimate the total yield of maize in the three northeast provinces of China from 2017 to 2019, the error between the predicted yield and the actual yield is less than 1%, indicating that the model has high accuracy and wide application prospect.

Key words: multiple regression analysis, crop yield, estimation model, gray correlation analysis, leading factor
