在毛主席的革命路线指引下,我省玉米杂交种在近两年发展很快,种植面积去年接近三百万亩,比文化大革命前增长六倍以上。实践证明,杂交玉米适应性广,抗逆力强,增产潜力大,一般比普通玉米品种增产百分之三十左右,有的甚至成倍地增产。推广玉米杂交种,是粮食达、超《纲要》的一项有力措施。玉米杂交种的优点和增产性能愈来愈为广大贫下中农所认识,迫切要求扩大种植面积。为了作好玉米杂交种的推广普及工作,现就生产上出现的几个问题提供一些意见,供讨论研究。一、单交种与顶、三、双交种综合利用,加快推广步伐 Guided by Chairman Mao’s revolutionary line, the corn hybrids in our province have been developing rapidly in recent two years. The acreage planted last year was nearly three million mu, an increase of more than six times that before the Cultural Revolution. Practice has proved that hybrid corn wide adaptability, strong anti-adversity, yield potential, generally more than ordinary corn varieties increased by about 30%, and some even doubled yield. Popularizing corn hybrids is a powerful measure for reaching foodstuffs and exceeding the “outline”. The advantages and yield-increasing performance of maize hybrids are increasingly recognized by the vast majority of poor and middle peasants and there is an urgent need to expand the planting area. In order to make the popularization and popularization of maize hybrids, some opinions on some issues that appear in the production are provided for discussion and research. First, a single cross-species and top, three, double cross-species comprehensive utilization, accelerate the pace of promotion
