摘　　要：两优289系安徽省农业科学院水稻研究所和湖北谷神科技有限公司选育的高产稳产两系杂交中籼稻新组合。全生育期135 d,株高110 cm,株型紧凑,耐肥抗倒,稳产高产。重点介绍了两优289机插秧高产栽培技术,包括育秧技术、机插技术、机插秧大田管理技术,以达到省工节本、增收增效的目的。Liangyou 289 is a newly released two-line mid-season indica rice hybrid bred collaboratively by the rice research institute of Anhui academy of agricultural sciences and Hubei Gushen Sci-Tech Co., Ltd.. Its growth period is 135 days. It has about 110 cm of plant height with a small leaf inclination angle. The variety is tolerant to over-fertilization and lodging, with high and stable yield potentials. The mechanic transplanting techniques for this variety including seedling raising technique, mechanic transplanting technique and the corresponding field management technique of mechanic transplanted rice seedlings were introduced. The techniques could realize objectives of cost-saving, labor-saving, yield-increasing and high efficiency.
