| 摘 要： | 以不同耐冷性品种吉粳81和长白9为供试材料,进行不同的磷肥施用量处理（施入磷酸二铵分别为0、40、80、120和160 kg/hm2）,对孕穗期低温胁迫下不同磷营养对水稻株高、穗抽出度、穗长、结实率以及单穴产量进行研究。结果表明,低温胁迫会抑制吉粳81和长白9植株生长,导致穗抽出度、穗长、结实率以及产量下降,且对非耐冷...

| Abstract: | Two different cold tolerant rice varieties,Jijing 81 and Changbai 9 were selected,and were transplanted into pot.P was added into pot at transplant stage and P concentration levels at 0,40,80,120 and 160 kg/hm2 respectively.Plant height,panicle neck length,panicle length,grain filling rate and yield were investigated under low temperature stress.The results showed that Plant height,panicle neck length,panicle length,grain filling rate and yield were decreased under low temperature stress.As the increasing o... |
