甘南县玉米种子生产已有20多 a(年)的历史,经历了双交种、三交种到单交种的过程,技术力量雄厚,经验丰富,历年繁种150～250万 kg 左右,除了满足全县农业生产用种外,还满足附近县及内蒙古的阿荣旗、扎兰屯、莫旗、扎莱特旗等地,信誉好,种子质量方面特别是去雄、去杂、纯度、净度、出芽率均表现出突出,多次受到省市种子部门的好评。近几年来,随着农业生产水平的改善提高,农业朝高产、优质、高效发展,受当地温度等气候因素影响,落后的繁种技术致使玉米制种陷入困境,每年只能繁殖一些早熟品种,面积小、产量低,生产基
Gannan County corn seed production has more than 20 years (years) of history, has gone through double cross species, the three cross-species to single cross-species process, strong technical force, experienced, over the years breeding 150 to 250 million kg or so, except To meet the county agricultural production, but also to meet the nearby counties and Inner Mongolia Arong Banner, Zalantun, Mo flag, Zalette flag and other places, reputable, the quality of seeds, especially to the male, to miscellaneous, purity, clarity, Budding rate are outstanding, many times by the provincial department of seedling praise. In recent years, along with the improvement of agricultural production level, the development of agriculture toward high yield, high quality and high efficiency is affected by the climatic factors such as local temperature. The backward variety of seed production technology makes corn seed production in trouble and can only breed some early-maturing varieties every year. Small size, low output, production base
