| 摘 要： | 以适合在黑龙江省第三积温带栽培的水稻品种（系）为材料，研究低磷对水稻形态特征及产量的影响，筛选出耐低磷材料，对黑龙江省水稻生产和土地持续利用具有重要意义。综合返青期叶片数和穗长分析认为：龙粳29、04-582 、龙粳21 、01-687 、05-4076 、06-2351等6份材料对低磷胁迫适应性较强。

| Abstract: | The experiment used cultivated rice varieties （lines） as materials,which was suitable for planting in the Third Accumulative Temperature Belt of Heilongjiang Province.The purpose of testing is to study the influence of rice morphological characteristics and yield under the salt stress and low-nutrition,and to screening barren-resistant materials and salinity-resistant materials.This study is significant to the rice production and sustainable land use of Heilongjiang Province.Through analysis with leaf number and panicle length data,the result showed that some materials had stronger tolerance low-phosphorus stress in greenturning period,such as Longjing 29,04-582,485,05-397,01-107,Longjing 21,03-805,Longjing 25,00-108,05-4035,01-687,Longjing 27,04-107,06-2351 and 05-4076,one of the strongest classification was Longjing 29.In classification treatment of panicle length,those materials had stronger classification,such as 04-582,Longjing 29,Longhua 00-446,Longjing 21,01-687,01-558,06-2351,05-4076 and Kendao 14,so those materials had stronger tolerance low-phosphorus stress.Composite result of leaf number and panicle length data showed that 6 rice materials had stronger tolerance low-phosphorus stress,such as Longjing 29,04-582,Longjing 21,01-687,05-4076 and 06-2351. |
