新华财经北京12月1日电题：从一粒稻种看中国种企创新路 新华社记者胡璐、周勉 冬日的清晨，海南陵水县椰林镇的湖南省南繁科研育种园安马洋基地。"这块田插两行，每行七株，那 块田得插四行。"这几天，袁隆平农业高科技股份有限公司科研人员孙振彪正忙着和大家一起人工栽插 水稻育种材料。 为了提高育种效率，隆平高科推动传统育种经验与现代生物技术结合，建立了覆盖生物技术、传统育 种、品种测试三大平台的商业化育种体系。通过组建国际先进的生物技术平台，应用种业集成产品研发 和数字化技术，使品种选育周期从之前的8到10年缩短至4到6年。此外，还自主研发了多个信息系统， 实现了种子从播种到收获的全程数字化管理。 隆平高科的发展，是在种业振兴行动的推动下，中国种企不断创新的生动缩影。 企业是种业振兴的骨干力量。为改变我国种企数量多、规模小、创新弱的状况，2021年农业农村部从3 万余家企业中遴选了农作物、畜禽、水产等270多家种业企业，构建"破难题、补短板、强优势"国家种 业企业阵型，推动与金融、科研、基地对接合作。 目前，种业企业牵头承担国家重大科技项目占比超过六成，金融机构为种业企业提供贷款3000多亿元， 农作物阵型企业研发投 ...

隆平高科水稻首席专家、副总裁杨远柱告诉记者，致力于实现更大的种业突破，隆平高科组建了一支 700多人的科研团队，并联合国内多名院士、多家知名科研院所，长期开展产学研合作。 新华社北京12月1日电 题：从一粒稻种看中国种企创新路 新华社记者胡璐、周勉 冬日的清晨，海南陵水县椰林镇的湖南省南繁科研育种园安马洋基地。"这块田插两行，每行七株，那 块田得插四行。"这几天，袁隆平农业高科技股份有限公司科研人员孙振彪正忙着和大家一起人工栽插 水稻育种材料。 海南温暖如春的天气，让秧苗长得格外快。600多亩的试验基地里，有的已是绿油油的一片。孙振彪 说，每个田块都是根据各自栽插的新品种特性和试验目的来精准控制栽插株数和时机的，期待明年3、4 月份能通过田间观察挑选出性状更好的育种材料。 种子是农业的"芯片"。半个世纪前，杂交水稻在中国率先成功研发并大面积推广，助力解决世界近五分 之一人口吃饭问题，并远播包括冈比亚在内的五大洲近70国。随着生活水平提高，人们肉蛋奶吃得多 了，需要越来越多的饲料粮来转化，对粮食的需求在不断扩大，对粮食品质的要求、多样化食物的需求 也在提高。 目前，种业企业牵头承担国家重大科技项目占比超过六成， ...
