吉林省现有耕地面积为400万公顷,玉米的常年播种面积240多万公顷,占60%。全省每年玉米需种量在1亿千克左右,玉米是吉林省的主要粮食作物,要想获得农业大丰收,必须有高质量的种子。加强种子质量管理,采取强有力的综合配套技术,达到提高玉米种子质量的目的。总结多年来杂交玉米种子生产经验,在实际中逐渐推广了一些新技术、新措施,起到提高玉米种子质量的作用。具体措施是:1 坚持原种全省统一繁殖、统一供应从源头抓起,坚持高标准,强化了质量意识。我省原种由省里统一繁殖,统一调拨,原种的质量有保证:一是种源有利于防杂保纯;二是标准一致,有利于田间
Jilin Province currently has 4 million hectares of arable land and more than 2.4 million hectares of perennial corn, accounting for 60% of the total.
