摘要:【目的】积极引导农民广泛应用超级稻,把超级稻示范推广拓展应用到水稻全面生产上来,为粮食增产增收提供指导。【方法】早晚造选择具有代表性的田块(或田垌),以当地主推超级稻与普遍种植的非超级稻品种作为对照进行试验示范并测产验收和统计每年产量。【结果】近3年(2014~2016年),累计推广应用超级稻面积.318万hm2,平均产量69.6kg/667m2,总产4.44万t,比对照平均产量增产1.8kg/667m2,总增产量4.13万t,增加产值13718.3万元,增幅达10.0%。【结论】利用超级稻理想株型可以大幅度提高单产、改良品质、增强抗性的生态特点,种植超级稻可以达到增产增收,较好利于解决粮食生产发展压力问题。

Abstract:【Objective】 o actively guide the farmers to widely apply super rice, applying super rice fully in production,demonstration and extension, so as to provide a guide for increasing of grain production.【Method 】 o select representative field plots for early and late season rice,then do experiment on locally, mainly recommended super rice and the ordinary non-super rice by comparison, finally measure and do statistics on yearly yield.【Results 】For the recent 3 years (2014~2016), the accumulated extension area of planting super rice is up to 3.18 thousand hm2,with average yield up to 69.6kg/667m2 and total yield up to 44.4 thousand tones, in comparison to the average yield, it is increased by 1.8kg/667m2, total increased yield is 41.3 thousand tones, production value is increased by CNY 137.183 million yuan with increased rate of 10%.【Conclusion 】 Unit yield can be largely increased by using the ideal super rice plant, the quality will be improved and its resistance will be enhanced,hence planting of super rice will reach the aim of yield-increasing and harvest-increasing, so that it is beneficial for solution of the development pressure on grain production.

八步區属亚热带季风气候,是传统双季稻作区,年平均气温达18~20.3℃,无霜期230~300d,≥12℃积温200~7026℃,年降水量130~2060mm,有充裕的光、热条件,非常适合超级稻的生长,有条件发展超级稻的面积超过2万hm2,占全区粮食播种面积的60%以上[1]。近年来,贺州市八步区把超级稻示范推广作为当前提高粮食产量、增加农民收入、实现农业增产增效的首要技术措施,积极引导农民广泛应用超级稻,把超级稻示范推广拓展应用到水稻全面生产上来。

八步区从2003年开始引进超级稻试验,2004年开始小面积示范,200年全区推广200hm2,2006年全区推广126.8hm2,发展到2016年超级稻种植面积已经接近2万多hm2,超级稻产量也从00kg/667m2,提高到600kg/667m2以上。据统计,2014~2016年共三年当中,在八步区辖区各乡镇、村等通过实施超级稻……
