干旱问题是我县农业生产上的突出问题之一。为了合理利用自然资源,发展山区旱作农业,必须采取合理的旱作农业耕作制。经试验示范证明,春麦夏播是发展旱作农业,发挥资源优势,提高生产力,改善人民生活,使山区人民尽快富起来的途径之一。一、增产效果1984年在海拔1,200米以上种植424.5亩,平均亩产101斤,较莜麦增产50—100%,在大旱之年获得较好收成。据阳原县气象站资料,在夏播小麦生育期间,降雨次数为32次,降雨量为126.6毫米,是常年的一半,对夏播小麦的生长及产量的形成阶段影响极大。在干旱的条件
Drought problem is one of the prominent problems in our county’s agricultural production. In order to make rational use of natural resources and develop dry farming in mountainous areas, it is necessary to adopt a reasonable dry farming system. The experimental demonstration proves that the summer wheat sowing is one of the ways to develop dry farming agriculture, make full use of its advantages in resources, increase productivity, improve people’s living conditions and make mountain people rich as soon as possible. First, the effect of increasing yield In 1984 198424 acres planted above 1,200 meters above sea level, the average yield of 101 pounds per mu, yield increased by 50-100% than oats, get better harvest in drought years. According to Yangyuan Meteorological Station data, during the summer sowing wheat, rainfall was 32 times, rainfall 126.6 mm, is the perennial half of summer sowing wheat growth and yield stage of the formation of great influence. In arid conditions
