冀中南是一个旱作粮区。据衡水气象站三十一年資料統計,年平均雨量449毫米,主要集中7、8两月,春季十年九旱,是当地农业生产上的首要問題。1962年,我們在前华北农业科学研究所1955~1956年对本地区抗旱耕作技术研究的基础上又从研究全年土壤水分动态規律的角度出发,探討了全年抗旱耕作技术問題。 Jizhongnan is a dry farming area. According to statistics from the Hengshui Weather Station for 31 years, the average annual rainfall is 449 mm, which is mainly concentrated in July, August and February and the spring drought in the past ten years. It is the primary issue in local agricultural production. In 1962, based on the previous research of North China Institute of Agricultural Sciences from 1955 to 1956 on drought-resistant farming techniques in the region and from the perspective of studying the dynamic law of soil moisture throughout the year, we discussed the technical problems of drought-resistant farming throughout the year.
