(一)安国县位于河北省中部,全县地势平坦,南部有沙河、滋河、小唐河、小青河,东西贯串40余里,沿河两岸地势洼下,土质黑粘较肥沃宜于种粮,但易遭秋涝为害;中部黄沙壤土,地势略高平坦,早涝易保收成;北部黄沙、碱土,水利条件不好,又易受春旱秋涝威胁。全县年平均降雨量600毫米左右,多集中在7、8月份,所以春旱秋涝现象极易形成,农作物产量低而不稳。1952年粮食总产13,416.81万斤,1954年因涝灾只收粮4,256.64万斤,1955年收成较好,但春季仍现旱象,小麦减产,粮食产量只恢复到9,768.6万斤。1956年又过洪水沥涝,粮食下降
(A) County is located in the central Hebei Province, the county flat, the southern Shahe, Zi River, the small Tanghe, Xiaoqing River, east-west runs through more than 40 miles along the banks of the terrain depression, soil black sticky more fertile in the species Grain, but vulnerable to autumn flood damage; the central yellow sandy loam, the terrain slightly flat, early flood and easy to ensure the harvest; northern yellow sand, alkaline earth, water conditions are not good, but also susceptible to spring floods threatened. The county’s average annual rainfall of about 600 mm, mostly concentrated in July and August, so spring and autumn fall flood easily formed, low and unstable crop yield. In 1952, the total grain output was 134.168 million kilograms. Only 4,256.64 million kilograms of grain were collected in flood-scarce 1954, and the harvest was good in 1955. However, there was still a dry climate in spring and the yield of wheat was reduced and the output of grain was only restored to 97.668 million kilograms. In 1956 floods and floods again, the food dropped
