以杂交稻汕优桂 99、博优 64为供试材料 ,研究了旱育小苗秧与常规育秧在某些农艺性状及产量效应等方面的差异。结果表明 :旱育小苗秧与常规育秧相比 ,旱育小苗秧具有早生快发、根系发达、植株健壮、生长势强、分蘖早、低位蘖多、有效穗多、结实率高、能提早抽穗、增产效果显著并具有省种、省工、省水、抗寒力强 ,利于抢季节 ,利于集约化育秧等优点 ,是一项值得应用推广的水稻高产栽培技术。
The hybrid rice “Shanyouyoung 99” and “Bo You 64” were used to study the difference of some agronomic traits and yield effects among the seedlings of dry-raising seedlings and conventional seedlings. The results showed that compared with the conventional seedlings, the seedlings of drought-tolerant young seedling had the characteristics of quick early-germination, rapid root system, strong plant growth, strong tillering, low tillering, more effective spikes and higher seed setting rate, , A significant yield-increasing effect and has the advantages of provincial species, provincial workers, provincial water, cold hardiness, conducive to grab the season, conducive to intensive nursery, etc., is a high-yielding cultivation technology worthy of popularization.
