石河子地区属于春播中晚熟玉米的适宜区,20世纪80年代引进的Sc704已证明,在该地区推广新品种有利于提高玉米的品质和产量。针对Sc704引进的时间长,品质有所下降等问题,引进山东省新的玉米品种,试验表明,登海1号、鲁玉15的生育特性、经济性状具有一定的优势,具有较大的增产潜力,试验为示范推广提供了依据。 The Shihezi area belongs to the suitable area for spring sowing middle and late maturing corn. Sc704 introduced in the 1980s has proved that popularizing new varieties in this area is beneficial to improve the quality and yield of corn. Aiming at the problems of long introduction of Sc704 and the decline of quality, the introduction of new maize varieties in Shandong Province showed that the growth traits and economic traits of Denghai 1 and Luyu 15 had certain advantages and had great potentials of increasing yield The experiment provided the basis for the demonstration promotion.
