Based on the grain yields and related data of Gansu Province from 2012 to 2021,the article analyzes nine indicators affecting grain yield in Gansu Province selected from three aspects,namely,natural factors,scientific and technological factors,and economic factors,using grey association study.The analysis results showed that:the effective irrigated area has the greatest influence on grain yield in Gansu Province,the influence of grain sowing area,fertilizer application and total power of agricultural machinery on grain yield gradually increases,while the per capita disposable income in rural areas has the least influence on grain yield in Gansu Province.Accordingly,suggestions for improving grain production in Gansu Province are put forward in terms of strictly abiding by the red line of arable land,increasing investment in science and technology,cultivating high-quality farmers and vigorously developing green agriculture.
