摘要
[目的]基于2016年第三次全国农业普查资料,分析宣城市粮食生产能力及其面积结构调整。[方法]在分析2016年宣城市耕地利用和粮食生产情况基础上,确定能发挥气候资源生产潜力的种植制度,以水稻高产创建项目、小麦玉米区域试验的产量为基础,计算宣城市粮食生产能力。结合主要粮食作物面积构成对比分析,提出粮食面积结构调整建议。[结果]全市粮食平均单产能力为8457.10 kg/hm^2,比2013—2015年的粮食实际平均单产高3089.66 kg/hm^2;粮食总生产能力为186.66万t,比2013—2015年粮食平均总产高68.19万t。全市粮食面积潜力36.1万hm^2。面积结构调整可考虑“提高稻谷、稳定小麦、适量增加玉米和大豆”。[结论]2016年全市粮食生产能力开发率为0.63,粮食生产潜力较大。可通过结构调整,使粮食面积中稻谷占74%、小麦占18%、玉米占4%、大豆占2%。
[Objective]Based on the data of the third national agricultural census in 2016,the grain production capacity and its area structure adjustment in Xuancheng City were analyzed.[Methods]Based on the analysis of cultivated land use and food production in Xuancheng City in 2016,determine the planting system that can exert the production potential of climate resources,and calculate the grain production capacity of Xuancheng City based on the high yield production project of rice and the yield of wheat and corn regional trials.Based on the comparative analysis of the area composition of main food crops,the paper proposes the adjustment of grain area structure.[Results]The average grain yield per liter of the city was 8457.10 kg/hm^2,which was 3089.66 kg/hm^2 higher than the actual average grain yield in 2013-2015.The total grain production capacity was 1,866,600 tons,which is the average grain output of 2013-2015.The height is 681,900 tons.The city’s grain area potential is 361,000 hm^2.Area structure adjustment can consider“improving rice,stabilizing wheat,and increasing corn and soybeans in moderation”.[Conclusion]In 2016,the city’s grain production capacity development rate was 0.63,and the grain production potential was large.Through structural adjustment,rice in the grain area accounts for 74%,wheat accounts for 18%,corn accounts for 4%,and soybean accounts foR^2%.
