Abstract[Objective] Accurate quantitative cultivation technology is a another great breakthrough of rice cultivation technology, the aim was to explore the accurate quantitative cultivation technology of Yongyou 538. [Method] Taking the yield of 12 750 kg/hm2 as target and according to the leaf age process, 3 farmers were chose, and the yield and group structure, sowing date and transplanting period were designed, and the key technologies such as nitrogen fertilizer use amount and irrigation were also designed accurately and quantitatively, then strictly enforced. [Result]Yongyou 538 was a new late rice line with dwar and big spiketype and crossed by indica rice and japonica rice, which was bred by Institute of Crops, Ningbo Academy of Agricultural Sciences and Ningbo City Seeds Co., Ltd, and had potential of superhigh yield. The superhigh yield target of 3 pieces of single cropping rice realized and their yield were 14806.80, 12 772.95, 13 135.35 kg/hm2, resp.. [Conclusion] The study provides a scientific basis for the accurate and quantitative cultivation of Yongyou 538.

收稿日期20140623水稻要取得高产一定要做好栽培良种、良法结合,只有良种与良法配套,才能充分挖掘该品种(组合)的生产潜力。甬优538是宁波市农业科学院作物研究所和宁波市种子有限公司育成的矮秆大穗型灿粳交晚稻新品系。水稻精确定量栽培技术是由杨州大学教授凌启鸿团队创立,是50多年水稻栽培技术研究成果的结晶,是水稻栽培技术的又一次突破。为挖掘甬优538组合超高产潜力,
1甬优538的品种特性
甬优538(甬粳3号A/F7538)是由宁波市农业科学院作物研究所和宁波市种子有限公司育成的矮秆大穗型灿粳交晚稻新品系,经2010~2012年3年区试示范,表现高产稳产、中熟、优质、强根、株高适中、壮秆、大穗、耐寒、抗倒,手插、直播皆宜,感光性中等,不同年度间生育期稳定。2011年在宁波鄞州区5月27日播种,9月1日齐穗,播齐历期97 d,全生育期162 d;6月24日播种,9月17日齐穗,播齐历期85 d,全生期149 d。作单季稻栽培总叶龄17叶,伸长节6节。
2实施地土壤条件
攻关田土壤类型为壤土,灌排方便,肥力水平高,钱利华农户前作为蔬菜,沈兴达前作为空白田,王正华农户前作为油菜。估计地力产量为6 750 kg/hm2左右,肥科当季利用率在41%。
