一、基本情况安徽省淮北地区粮食作物主要有小麦、甘薯、大豆、玉米、高粱等。1981年全区粮食总产63.5亿公斤,其中夏粮2000万亩,总产30亿公斤,单产146公斤,总产比1949年增长1.2倍,比1978年增长42.0％。全区还有三分之二的耕地,亩产仅200公斤,处于中低产水平。淮北地区农业生产存在的主要问题:一是早涝灾害频繁;二是低产土壤面积大;三是作物结构布局不够合理;四是科学种田水平比较低。因此,开发研究中低产地区夏秋粮均衡增产技术,特别是秋粮均衡增产技术,发挥这个地区的生产优势,挖掘生产潜力,必将大幅度提高粮食产量。
First, the basic situation The main crops in Huaibei area of Anhui Province are wheat, sweet potato, soybean, corn, sorghum and so on. In 1981, the total output of grain in the region was 6.35 billion kilograms, of which 20 million mu were summer cereals, with a total output of 3.0 billion kilograms and a yield of 146 kilograms. Its total output grew 1.2 times that of 1949 and an increase of 42.0% over 1978. There are two-thirds of the cultivated land in the region, with a yield of only 200 kg per mu, which is at the middle-low yield level. The main problems in agricultural production in Huaibei are as follows: First, frequent floods and floods; second, low-yielding soil area; thirdly, crop structure and layout are not reasonable enough; fourthly, the scientific farming level is relatively low. Therefore, the development and research of summer and autumn grain balanced production technology in low-yielding areas, especially the balanced growth of autumn grain production technology, to play in the production advantages of this region, tap the potential of production, will significantly improve food production.
