[中文]选择主要由**育成的17个超级稻和已审定推广及特别优秀的组合为材料进行示范展示,其中籼杂单晚新组合8个、连晚6个和粳杂单晚3个,分别以两优培九、中浙优86和嘉优2号为对照;前作为油菜或冬闲田,土壤为青紫泥,肥力中上。展示田总共有15块田,每块田面积为3.2亩,总共47.8亩。其中12个组合各种一块田,面积为3.2亩,4个组合种各种半块田,面积为1.6亩,3个新组合种2/3块田,面积为2.1亩。单晚籼杂和杂交粳稻5月27日播种,6月16日移栽,连晚杂交籼稻6月8日播种,7月3日移栽。杂交籼稻移栽规格为30cm×20cm,即每公顷栽16.65万丛,内2优6号和杂交粳稻移栽规格为30 cm×16.7cm,即每公顷插19.95万丛。每公顷总施氮量为180kg,P2O5为67.5kg,K2O为130.5kg。氮肥分基肥、分蘖肥、穗肥按50:35:15的比例施用,磷肥全做基肥,钾肥分基肥和穗肥两次施用,每次用量1/2。其他管理同高产田块。[/中文] [外文]Seventeen elite super hybrid rice combinations, mostly bred by **, were selected for demonstration. Of which eight belong to late-season indica hybrids (single-cropping), six to late rice(continuous cropping) and three to late-season japonica hybrids(single-cropping) with Liangyoupeijiu, Zhongzheyou 86 and Jiayou 2 as the control, respectively. With rape as the preceding crop or winter fallow, the chosen combinations were grown in blue clayey paddy soil with moderate to high fertility. The demonstration paddy field includes 15 plots averaging 3.2 mu per plot,covering an total area of 47.8 mu. Twelve combinations each was grown in one plot, 4 combinations each in a half of one plot, occupying 1.6 mu and 3 combinations each in two-thirds of one plot, occupying 2.1 mu. Single-cropping indica hybrids and japonica hybrids were sown on May 27 and transplanted on June 16, and for continuous cropping late rice, on June 8 and July 3. The single-cropping indica hybrids were transplanted at a spacing of 30cm×20cm, namely 1.665 million hills per hectare. The japonica hybrids and Nei 2 you 6 were transplanted at spacing of 30 cm×16.7cm, namely 1.995 million hills per hectare. The application rates of nitrogen, potass(P2O5) and phosphorus(K2O) were 180 kg,67.5kg and 130.5kg per hectare, respectively. Nitrogen fertilizer was applied as basal fertilizer, top dressing at tillering stage and topdressing at panicle formation stage at a rate of 50:35:15. Phosphorus fertilizer was applied as basal fertilizer and potass fertilizer as basal fertilizer and topdressing at panicle formation at a rate of 1:1. Other management measures were in accordance with high-yielding cultivation.[/外文]
