【摘要】 甘肃河西走廊气候干燥,水热资源丰富,是适宜的牧草种子生产区域。2001年以来,通过中国农业大学与酒泉大业种业在当地开展草种产业化技术的研究与生产示范,推广应用禾本科和豆科牧草种子高产关键技术后,在较大面积生产条件下,无芒雀麦、高羊茅、蓝茎冰草、草地早熟禾、扁穗冰草等禾本科已具备较高的大田平均种子产量。新麦草需结合冬季放牧,可进一步提高种子的单产水平。在当地现有的生产条件下,牧草种子的收获时间和收获技术是影响种子产量的主要因素之一。与当地其他作物制种及主要农作物生产相比,在种子产量相对较高的情况下,农户进行草种生产的经济效益还比较低,草种产业在当地发展还存在着不稳定性。与美国等发达国家相比,在我国河西走廊草种生产的适宜地区,除进一步提高生产水平外,草种产业的发展还依赖于草产业对优良品种种子需求的提高。更多还原

【Abstract】 Hexi Corridor located in Gansu province,China,with a dry weather condition and promising irrigation and accumulation temperature resources,is a proper area for forage seed production.Since 2001,forage seed production researches and extension activities were conducted by China Agricultural University and Jiuquan Daye Forage Seed Co.Ltd. in that area,aimed for forage seed industry development.By application of some key grass and legume seed production management methods,calculated on a relative large field area,grasses such as smooth bromegrass,tall fescue,western wheatgrass,Kentucky bluegrass,crested wheatgrass etc.demonstrated a higher average field seed yield.But unless by a winter grazing measurement,seed yield of Russian wildrye was low.Under current production condition in Hexi Corridor, seed harvesting date and harvesting management still a problem to cause seed losses in the field.Compared with other agronomy crops,even with a high seed yield,the economic benefit of forage seed production was lower,that is a negative factor for development of the industry in local area.In the final,the authors concluded that it is the requirement of improved cultivars evolved to forage industry in China that will underpin the forage seed industry in Hexi Corridor.更多还原
