Abstract:

To enhance grain production effectively by gray correlation analysis, and research the influence of grain production, 9 factors impacting grain production prominently as follows were selected to establish indices system: cultivated land area, grain planting area, yield per unit, effective irrigation area, using amount of fertilizer, agricultural labor forces, using amount of electric, the total power of agricultural machinery, the damaged area of crops. We used correlation analysis to analyze the results. It showed that, grain planting area was still the principal factor impacting the total output of grain. Those were using amount of fertilizer and it was still the principal factor impacting the total output of grain in Suining City. The yield per unit and cultivated land area were the two most important factors responsible for decrease of grain output. The effective irrigation area and the damaged area of crops were the two primary factors impacting the increase of grain output. The using amount of electric showed dwindling impact on grain production; agricultural labor forced still hovers at the minuscule impact degree on grain production. Through analysis of several impacting factors, proposing suggestion could be to enhance grain production.
