安徽省粮食生产能力研究与分析

安徽省粮食丰产科技工程中粮食作物的产量是当前自然和技术条件下可以实现的产量,用该单产水平计算安徽省粮食生产能力更具现实意义。本文以全省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。研究结果表明: 全省粮食平均单产能力为8029.47kg•hm-2，约是近3年安徽省粮食实际单产的1.37倍；全省粮食总生产能力为483.62亿kg，每年能为安徽省增加粮食产量近158.93亿kg。

Research and Analysis of the Capacity of Grain Production in Anhui

The yield of Anhui Science and technology project for food production is a reachable yield under the current natural and technical condition. Based on this yield of the Science and technology project for food production, it is much precise to calculate the total capacity of grain potential productivity of arable land in Anhui. 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. The results showed that: the average grain potential productivity of the whole province was 8029.47 kg•hm-2, be approximately 1.37 times of the past three years of Anhui Province grain actual per unit area yield, total grain potential production of the province to 48.362 billion kilogram, it can increase nearly 15.893 billion kilogram per year for Anhui province.
