京山公路两侧是全省建设稳产高产农田规划的东片中心,也是唐山专区商品粮食的主要生产基地。地势平坦,土质肥沃,雨量充沛,地下水利资源比较丰富,历来是粮食高产地区。但近几年来粮食产量的上升幅度,却远远落后于条件较差的北部地区。以丰润县韩城工委为例,1964年粮食平均播种亩产仅295斤(有部分洼地受涝灾),距离农 Jingshan highway on both sides of the province is building a stable and high yield farmland planning East Center, is also the main production base of Tangshan Prefecture commodity grain.

However, the increase in grain output in recent years has lagged far behind that of the less prosperous northern region. Take Fengrun County Hancheng Work Committee as an example. In 1964, the average grain output per mu was only 295 kg (with some depressions being flooded)
