为探明不同生态条件下超级杂交稻产量与氮、磷、钾养分的吸收积累特点及其基因型差异。以两优培九、中浙优1号等8个代表性的超级杂交稻品种为材料,普通杂交稻汕优63和超级常规稻胜泰1号为对照,于2007—2009年在湖南省桂东、长沙、南县进行了大田栽培试验。结果表明不同基因型超级杂交稻产量与氮磷钾养分吸收量的地点间、年度间、品种间差异显著。不同超级杂交稻品种产量3年3地点平均为9.32~10.25 t/hm~2,比汕优63增产5.1%~15.6%,比胜泰1号增产8.9%~19.7%;氮、磷、钾养分需要量分别为18.48~19.85 kg,3.75~4.63 kg和15.90~17.40 kg;氮、磷、钾养分吸收量分别为177.69~189.09 kg/hm~2,36.94~39.80 ...

Rice is one of the most important staple food crop in China and other Asian countries.Breeding high yielding varieties and improving resource-use efficiency are eternal themes in the areas of both rice research and rice production.In recent years,many super hybrid rice varieties with high yield potential have been widely grown by rice farmers in China,but the rule of nutrient uptake and accumulation is not fully clear.This paper attempted to ascertain the characteristics and genetic differences of grain yield performance and nitrogen（N）,phosp...
