一九六四年秋季,我们以田间排水为主题,对新疆生产建设兵团一些军垦农场的盐土改良综合经验,进行了一次调查学习,收获不少,给我们对华北平原土壤盐碱化的防治提供了许多启示。 这次调查,主要到了南疆的四团、五团、六团、塔里木四场,东疆的红星二场和北疆的三十团等六个农场。这些农场都处于冲积洪积扇缘或冲积洪积平原地带,地面坡降一般是1/1,000—5,000,个别最大的到1/200。气候特别干旱,年平均雨量最少者不足10毫米,最多为170毫米,而年蒸发量则均在2,000—2,500毫米上下。因此大部分地区垦前一米土层平均含盐量都在1—3％,个别地区甚至超过10％。
In the autumn of 1964, with the theme of field drainage, we carried out a survey and study and learned a great deal about the comprehensive experience of improving salt and soil in some of the Xinjiang Production and Construction Corps. We have provided us with some suggestions on the prevention and treatment of soil salinization in the North China Plain A lot of inspiration. The survey mainly came to four farms in southern Xinjiang, five regiments and six regiments, four in Tarim, two Red Star in Dongjiang and thirty groups in northern Xinjiang. These farms are located in alluvial alluvial fan or alluvial plains, the ground slope is generally 1 / 1,000-5,000, some of the largest to 1/200. The climate is particularly arid with annual mean rainfall of less than 10 millimeters and maximum of 170 millimeters, while annual evapotranspiration is between 2,000 and 2,500 millimeters. Therefore, the average salinity of one meter of cultivated land in most areas is 1-3%, even more than 10% in some areas.
