实现水平梯田稳产高产,对山区农业的发展有重要意义。被称作西山大寨的临县孙家沟大队,在这方面有较多的经验。这个大队山地占97.7％,他们从1957年开始修建水平梯田,至今已修成738亩。随着水平梯田的修建,粮食产量不断增加,1964年比1957年提高1倍以上。与邻近生产大队比较,1961年以来,产量连年领先。1965年,虽遭到百年不遇的严重旱灾,但粮食单产和总产仍超过1963年水平。孙家沟大队的水平梯田产量,不论是平年或是灾年,不论是粮食平均产量或是各种作物产量,均比坡耕地高,水平梯田的粮食产量占总产的比重愈来愈
Achieving stable and high-yield terraces is of great significance to the development of agriculture in mountainous areas. Known as Xishan Dazhai County Sunjiagou Brigade, in this area have more experience. The brigade hills account for 97.7%. They built horizontal terraces since 1957 and have so far completed 738 mu. With the construction of horizontal terraces, the grain output increased continuously, more than doubled in 1964 compared with 1957. Compared with the neighboring production brigades, since 1961, the output leads year after year. In 1965, despite the grave drought hit in a century, the yield per unit of food and the total output still exceeded the level of 1963. Sunjiagou brigade horizontal terrace production, whether it is flat or disaster year, whether it is the average yield of grain or a variety of crop production, than the sloping land, the proportion of grain output in the terraced fields of the total output more and more
