晚稻旱育秧与普通育秧方式相比,具有十分明显的优势:一是旱育秧发根力强,其发根具有很强的暴发力,返青快;二是根系发达,秧苗白根多,根毛多,移栽后吸肥力特强;三是分蘖力强,分蘖速度快,能迅速搭起丰产苗架;四是早育秧苗体矮壮,成穗节位低,茎秆粗壮,抗逆力强。尤溪县从1994年开始就将早育秧技术广泛应用到晚稻,6年来已累计在晚稻推广旱育秧技术54.7万亩,与同类型田普育普栽相比平均亩增稻谷38.5公斤.总产增2105.95万公斤,增幅达9.42％,取得显著成效。晚稻旱育秧的技术要点是:
Compared with the normal seedling cultivation, late rice dry seedling has obvious advantages: First, the dry seedling has strong rooting power and its hair root has strong outburst force and fast greening; second, root system is developed, white root seedling and root hair are more, Thirdly, it has strong tillering ability and fast tillering speed, which can quickly set up the seedling-raising frame. Fourthly, the seedling of early seedling is short and strong, the stalk is low, the stalk is strong, and the resistance is strong. Youxi County has been applying early seedling technology to late rice since 1994. In the past six years, it has accumulated a total of 547,000 mu of dry-seedling technology in late rice and an average of 38.5 kilograms of paddy per mu Increased by 20,059,500 kg, an increase of 9.42%, achieved remarkable results. Late rice dry seedlings Yang technical points are:
