Analysis of factors influencing grain production in Z City
Based on the data related to grain production in Z City from 2013 to 2023,14 factors including the total power of agricultural machinery in grain production,the amount of chemical fertilizers used in grain production,and the average temperature were selected.The grey correlation method and correlation analysis method were used to analyze the key factors affecting the grain yield in the study area,and the correlation between grain yield and the proportion of some grain crops area to grain planting area was analyzed.The results indicated that there was a strong correlation between the grain yield in the study area and the total power of agricultural machinery in grain production,the proportion of potato area to grain area,and the sowing area of grain.There was a statistically significant correlation(P<0.01)between the amount of chemical fertilizer applied in grain production and the sowing area of grain,a statistically significant correlation(P<0.05)with the proportion of corn area to grain area,and a statistically significant correlation(P<0.05)with the proportion of potato area to grain area.The correlation between grain yield and the proportion of rice area to grain area was statistically significant(P<0.01),and the correlation with the proportion of legume area to grain area was statistically significant(P<0.05).Taking into account factors such as zero growth in fertilizer application and limited arable land area,increasing the proportion of rice and corn planting area to grain area,while reducing the proportion of potato planting area to grain area,was beneficial for improving grain yield and promoting grain yield increase in the research area.
