水稻高产栽培必须良种与良法相配套。采用自主集成创新技术——钵盘营养土旱育秧超稀摆栽高产高效综合技术和超级稻“早稀控大壮”软盘旱育秧农机农艺配套高产栽培技术,在同等条件下进行栽培对比示范,产量差异明显。人工稀摆秧方式能更好地发挥超级稻品种生产潜力,生长势强、剑叶长、后期光合面积大、纹枯病发生轻、穗大粒多;机械插秧栽培则表现为结实率高、千粒重较重。8个品种中,广两优1128和深08S/R1128的2种栽培方式均表现较好。2套栽培技术均以提高秧苗素质为重点,加上改进规范人工抛秧和机插秧栽培的关键操作管理方法,更适宜于本地大面积推广超级稻品种时配套应用。
High yielding cultivation of rice must be complemented by good methods. The use of independent innovation and integrated technology - bowl dish nutrition drought dry seedling transplanting planted high yield and high efficiency integrated technology and super rice “early dilute control Dazhuang ” floppy disk dry seedling farming machinery agronomy supporting high-yielding cultivation techniques, under the same conditions for cultivation contrast Demonstration, the output difference is obvious. Artificial sparse planting method can give play to the production potential of super rice varieties better, strong growth potential, long flag leaf, late photosynthetic area, sheath blight occurrence of light, spike large grain and more; mechanical transplanting cultivation showed strong seedling rate, Heavier Among the eight cultivars, two cultivation methods of Guangliangyou 1128 and Shen 08S / R1128 performed well. Two sets of cultivation techniques are to improve the quality of seedlings as the key, coupled with improved regulation of artificial throwing and machine transplanting cultivation of key operational management methods, more suitable for large-scale popularization of super rice varieties supporting the application.
