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水稻要取得高產一定要做好栽培良種、良法結合,只有良種與良法配套,才能充分挖掘該品種(組合)的生產潛力。甬優538是寧波市農業科學院作物研究所和寧波市種子有限公司育成的矮稈大穗型燦粳交晚稻新品系。水稻精確定量栽培技術是由楊州大學教授凌啟鴻團隊創立,是50多年水稻栽培技術研究成果的結晶,是水稻栽培技術的又一次突破。為挖掘甬優538組合超高產潛力,
1甬優538的品種特性
甬優538(甬粳3號A/F7538)是由寧波市農業科學院作物研究所和寧波市種子有限公司育成的矮稈大穗型燦粳交晚稻新品系,經2010~2012年3年區試示范,表現高產穩產、中熟、優質、強根、株高適中、壯稈、大穗、耐寒、抗倒,手插、直播皆宜,感光性中等,不同年度間生育期穩定。2011年在寧波鄞州區5月27日播種,9月1日齊穗,播齊歷期97 d,全生育期162 d;6月24日播種,9月17日齊穗,播齊歷期85 d,全生期149 d。作單季稻栽培總葉齡17葉,伸長節6節。
2實施地土壤條件
攻關田土壤類型為壤土,灌排方便,肥力水平高,錢利華農戶前作為蔬菜,沈興達前作為空白田,王正華農戶前作為油菜。估計地力產量為6 750 kg/hm2左右,肥科當季利用率在41%。
