【摘要】 2012年在惠州会达菜场进行了一季中晚稻旱直播栽培技术研究,结果表明:一季中晚稻旱直播每667 m2产量为491.84～582.80 kg,在水管的条件下产量水平较高,每667 m2比湿润管理增产35.93～38.71 kg,增幅7.11%～7.31%,差异达显著水平;水管的分蘖力较强、最高苗数和有效穗数较多,植株较粗壮、穗子较大、穗粒数较多,群体的颖花数较多,籽粒充实饱满,千粒重较大;水管还表现出根量较大、根系发达,白根数较少、根活力较弱,稻米的蛋白质含量降低、直链淀粉含量上升。更多还原

【Abstract】 Study on cultivation technique of dry direct-seeded for single-middle-late season rice was carried out in Huizhou Huida vegetable farm in 2012. The results showed that, the yield of dry direct seeding cultivation technique of single-middle-late season rice was 491.84～582.80 kg per 667 m2. The yield of live in water had higher yield level, significantly increased 35.93～38.71 kg per 667 m2than moisture management, with increasing rate of 7.11%～7.31%. Under the condition of live in water for rice, the tillering ability was strong, highest number of seedlings and effective panicles was big, plants was stout, ears was large, grain number per spike was big,spikelets was much, grain was full, 1 000-grain weight was big; amount of roots was large, root was developed, number of white roots was small, root activity was weak; and protein content of rice decreased, amylose content of rice increased.更多还原
