【Abstract】 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.更多还原
