由国家杂交水稻工程研究中心育成的超级稻P88S/0293于2003年早季在三亚市荔枝沟试种773m^2,经海南省农业厅组织验收,产量达827.08k/667m^2,这是海南水稻栽培史上的重大突破。为进一步探讨该组合在高肥条件下的适宜栽插密度,特设本试验,现将试验结果总结如下。  相似文献

两系超级稻P88S/0293是国家杂交水稻工程技术研究中心配制的一个超高产组合。该组合是继成功育成两优培九先锋组合的基础上又一次质的飞跃,经多点试验示范,亩产稳定在800kg以上,而且米质优良,但它的制种产量低,难以满足大面积推广的需要。为了将该组合尽快转化为生产力,2004年袁隆平院士把两系超级稻P88S/0293制种攻关交给麻阳县。  相似文献

超级稻新组合P88S/0293肥料运筹技术的研究   总被引:2,自引:0,他引:2  
在海南中上肥力的土壤上,分别进行了超级稻新组合P88S/0293的氮磷钾肥不同施用量的肥料运筹试验。结果表明,氮磷钾肥的施肥量与超级稻新组合P88S/0293的产量、产量构成因子、生育期、植株性状、抗性等关系非常密切。该组合获得高产的合理施肥量为N(纯氮)300kg/hm^2,P2O5(五氧化二磷)150kg/hm^2,K2O(氧化钾)300kg/hm^2,三者的比例m(N):m(P2O5):m(K2O)=1.0:0.5:1.0。  相似文献

[目的]通过比较超级稻P88S/0389与其亲本P88S和R0389剑叶的光合特性,探索P88S/0389高产的光合机理。[方法]采用W ellburn和Lichenthaler的方法测定剑叶叶绿素及类胡萝卜素含量,并使用便携式光合测定仪测定光合速率及叶绿素荧光参数。[结果]杂交种的叶绿素含量居于双亲之间,生育期前期偏母本而后期偏父本;同时,杂交种有较强的光能吸收、转化和碳固定能力,其剑叶的净光合速率(Pn)、PSⅡ活性(FV/FO)和PSⅡ原初光能转化效率(FV/Fm)、叶绿素荧光光化学猝灭系数(qP)等参数均高于亲本,且下降速率都比亲本慢,非光化学猝灭(qN)较亲本低,上升速率也比亲本慢,表现出不易早衰等超亲优势。[结论]杂交种P88S/0389吸收的光能主要用于光化学反应,热耗散较少。在水稻生产中,选择同时具有较高光合速率和较长的光合速率高值持续期的品种对水稻的高产尤为重要。  相似文献

2004年早造,结合超级杂交稻新组合P88S/0293在三亚和澄迈的两个百亩片试种示范项目,我们安排了平衡施肥效应试验。试验结果表明:超级稻的养分吸收比例范围为纯氮:五氧化二磷:氧化钾=100:17-18:88-118。其高产平衡施肥技术为:(1)三亚点土壤肥力中等,土质沙质,该点在施了3000kg/hm2生物有机肥的基础上,其高产超级稻化肥适宜用量为纯氮300kg/hm^2、五氧化二磷150kg/hm^2、氧化钾300kg/hm^2。(2)澄迈点土壤肥力中上,质地中壤,该点没施有机肥,其高产超级稻化肥适宜用量为纯氮375kg/hm^2、五氧化二磷150kg/hm^2、氧化钾450kg/hm^2。两点施肥比例范围为100:40-50:100-20。  相似文献

超级稻P88S/0389光合特性初探(英文)   总被引:2,自引:0,他引:2  
[Objective] The aim of this study is to understand the high yield often photosynthetic mechanism of super hybrid rice P88S/0389.[Method] Chlorophyll and carotenoid contents were measured via the method of Wellburn and Lichtenthaler,and the photosynthetic rate and chlorophyll fluorescence parameters were measured using portable photosynthesis system.Through comparison of above measured indices between P88S/0389 and its parents,the photosynthetic characteristics were obtained.[Result] The pigment content of P88S/0389 lied between their parents,and detailedly was closer to its female parent at earlier growth stage and to its male parent at latter stage,respectively.The Pn,Fv/Fo,Fv/Fm and qP of the flag leaf of P88S/0389 were all higher than those of its parents,while the degradation rates of these parameters were slower than those of its parents.The qN of flag leaf was lower than those of its parents,and the increasing rate of qN of P88S/0389 was also slower than those of its parents,indicating the great heterosis of P88S/0389 to its parents in photosynthetic capacity.The data show that P88S/0389 is endowed with stronger capacities in light energy absorption,transformation and carbon fixation compared to its parents.[Conclusion] The light energy absorbed by hybrid mainly contributes to photochemical reaction,and little for heat dissipation.For ensuring high yield,the rice cultivars selected for production should synchronously possess higher photosynthetic rate and longer high value duration.  相似文献

“Ⅱ优明86”系福建省三明市农科所育成的大穗、高产、优质、抗病型超级杂交稻组合,也是目前我乡推广的超级稻组合中产量最高、稳产性最好的组合。近5年的示范种植中,因技术不到位,一般亩产只有500kg左右,个别高产田块550~600kg。究其原因,一是亩穗数不足,一般亩有效穗数在12~1  相似文献
