玉米是新疆兵团主要粮食作物之一,年均播种面积70万亩以上,近几年来,兵团进一步加强农业的基础地位,合理调整了农业产业结构,坚持稳粮、增棉的指导思想,使粮食产量稳步发展,目前,玉米生产的主攻方向是提高单位面积产量,采用优良品种则是玉米增产诸因素中投资少、见效快、效益高的技术措施。据有关资料表明,玉米杂交种子纯度每提高一个百分点就可提高单产5%左右。“九五”期间,兵团玉米主栽品种SC704纯度1995年为84.5%,1996年为89.4%,1997年为93.1%,玉米种子质量在较大幅度的提高,但据国家规定的最低标准96%还相差近3
Corps is one of the major grain crops of the Xinjiang Corps. The average annual sown area is more than 700,000 mu. In recent years, Corps has further strengthened the basic position of agriculture, rationally adjusted the industrial structure of agriculture, adhered to the guiding principle of stabilizing grain and increasing cotton, The output has been developing steadily. At present, the main direction of corn production is to increase the yield per unit area. The adoption of fine varieties is the technical measure of less investment, quicker and more effective in the increase of corn output. According to the data show that the purity of maize hybrids increased by one percentage point per unit yield can increase about 5%. During the 9th Five-Year Plan period, the purity of corn cultivars SC704 was 84.5% in 1995, 89.4% in 1996 and 93.1% in 1997. The quality of maize seeds was greatly improved. However, according to the national minimum standards 96% still a difference of nearly 3
