宁镇扬丘陵地区位于我省西南部,地跨长江两岸,包括南京市的六合、江浦、江宁、溧水、高淳,镇江市的句容、丹徒、丹阳,常州市的金坛、溧阳,无锡市的宜兴,扬州市的仪征、邗江、高邮和淮阴市的(贝于)贻等共15个县(上述各市的郊区未列入内)的丘陵地区。这15个丘陵县近几年来种植小(大)麦650万亩左右,其中,纯丘陵地区种麦面积约310万亩左右,这是我省小(大)麦生产上的老低产地区。建国以来,小(大)麦的单产一直低于全省水平。据典型调查统计:在50年代,全省夏粮平均单产为53.8公斤,而那时宁镇扬丘陵地区的原镇江地区602万亩小(大)麦,平均亩产为49.5公斤,比全省单产低4.3公斤,降低8％;60年代的1965年全省夏粮平均亩产91公斤,宁镇扬地
Ningyangyang hilly area is located in the southwest of our province, across the Yangtze River, including Nanjing, Liuhe, Jiangpu, Jiangning, Lishui, Gaochun, Zhenjiang City, Jurong, Dantu, Danyang, Changzhou Jintan, Liyang, Wuxi Yixing City, Yizheng City, Yangzhou City, Yijiang River, Gaoyou City, and Huaiyin City (Bayu County), and other 15 counties (the suburbs of these cities are not listed). In these 15 hilly counties, about 6.5 million mu of small (large) wheat is planted in recent years, of which about 3.1 million mu are planted with wheat in pure hilly areas. This is an old and low-producing area in the small (large) wheat production in our province. Since the founding of the People’s Republic, the yield of small (large) wheat has been below the province level. According to the typical survey and statistics, in the 1950s, the average yield of summer grain in the province was 53.8 kg, while that of the 602 million mu of small (large) wheat in the original Zhenjiang area in Ningyangyang hilly area was 49.5 kg per mu, Low 4.3 kg, down 8%; 1960’s in 1965 the province’s summer average yield per mu 91 kg,
