在小麦播种之前,对种子进行风选、筛选、精选和盐、泥水选等,是提高种子质量的传统办法。随着农业机械化的发展,逐步实现种子处理、加工机械化,更好地提高种子质量是整个播种小麦工作的主要组成部份。目前,我区已有大型精选机55台,小型筛选机13台。1979年共加工精选小麦良种1800万斤,播种面积72万亩。今年计划精选小麦种子1亿斤,播种面积达到400万亩。
Prior to sowing of wheat, it is the traditional way to improve the quality of seeds by carrying out wind selection, screening, selection and selection of salt and muddy water on the seeds. With the development of agricultural mechanization, gradual realization of seed treatment, mechanization of processing and better seed quality are the major components of the whole sown wheat work. At present, there are 55 large selection machines and 13 small screening machines in our district. In 1979 a total of 18 million kg of wheat seeds were selected for processing and the sown area was 72 million mu. This year plans to select 1 million pounds of wheat seeds, sown area of 400 mu.
