摘要
【目的】研究在现有生产水平条件下安徽省的粮食生产能力;【方法】该文以全省13个农业生态小区为研究单元,确定了能够充分发挥当地气候生产潜力的种植制度,并以粮食丰产科技工程中粮食作物试验产量为基础,计算了各农业生态小区粮食生产能力和总的粮食生产能力;【结果】全省粮食平均单产能力为8029.47kg/hm2,与近3年(2005—2007)粮食平均单产(5390.68kg/hm2)相比,单位面积耕地的增产潜力为2638.79kg/hm2;全省粮食总生产能力为483.62亿kg,高于近3年(2005—2007年)324.69亿kg的粮食平均总产,每年能为安徽省增加粮食产量近158.93亿kg;【结论】目前全省粮食生产能力的开发率为0.67,粮食生产潜力依然很大。
[OBJECTIVE]Research the grain production capacity in Anhui province under the existing level of production; [METHOD] In the study 13 agro-ecological regions was selected as study area and the potential productivity of grain was analyzed; and cropping system in every agro-ecological region was determined under the principle that the water and thermal potential could be sufficiently developed; based on the yield of the Science and technology project for food production, the potential unit yield of crop for every agro-ecological region and the total grain production capacity was calculated. [RESULTS] The average grain potential productivity of the whole province was 8029.47 kg/hm^2, compared to near 3-year（2005--2007） average yield of grain（5390.68 kg/hm^2）, yield potential of cultivated /and can increase 2638.79 kg/hm^2 per unit area ; The province＇s total grain production capacity was 48.362 billion kilogram, higher than the near 3 years （2005-- 2007） 32.469 billion kilogram of food the average total production .It can increase nearly 15.893 billion kilogram per year for Anhui province. [CONCLUSION] At present, the development rate of the grain production capacity was 0.67,it still had great potential for food production.
