广西玉米产区,大部分处于边远山区,部分在丘陵地带。全区800万亩玉米地,除部分旱田及少量旱地水肥条件较好外,大部分是靠天、土瘦、肥少的旱地,自然灾害频繁,生产水平低。因此,对玉米良种要求具有较强的抗逆性及适应性,以取得在不良环境中的稳产增产。 Guangxi corn producing areas, most of which are in remote mountainous areas, some in the hilly areas. The area of ​​8,000,000 acres of corn land, except for some dry land and a small amount of dry land water and fertilizer conditions are better, mostly by days, thin, fat little dry land, frequent natural disasters, low production levels. Therefore, the requirements for improved varieties of corn have a strong resistance and adaptability in order to achieve steady production in adverse environments.
