用种量大、秧龄期短、秧苗素质差、早晚季品种搭配难等,是全球杂交稻机插秧面对的共同的技术难题。最近,湖南农业大学科研团队历经五年,所做的“杂交稻单本密植机插高产高效栽培技术”攻关研究,获得了在杂交稻机插秧栽培技术上的有效突破:可使种子成本下降75%,秧龄延 With a large amount of seedling age is short, poor quality of seedlings, early and late varieties with difficult to wait, is the global hybrid rice seedlings face common technical problems. Recently, research team of Hunan Agricultural University, after five years, made “hybrid rice single plant close planting high yield and efficient cultivation techniques ” research, access to hybrid rice transplanting rice cultivation technology effective breakthrough: can make the cost of seeds Decreased 75%, seedling delay
