| 摘 要： | 采用盆栽法研究了不同盐碱度对水稻分蘖数、分蘖前期和分蘖末期干物质积累状况及产量的影响。结果表明:盐碱胁迫推迟了一次分蘖的时间,降低了水稻分蘖数和有效分蘖数约50%。随盐碱胁迫加强,水稻干物质积累的变化趋势为轻度>对照>中度>重度,产量的变化趋势为对照>轻度>中度>重度。

| Abstract: | By pot growing method,effects of different salinity-alkalinity complex stress on tiller number and dry matter accumulation of rice were studied.The results showed that salinity-alkalinity stress postponed the beginning time of the first tiller,reduced by 50% of tiller number and effective tiller number.With the development of salinity-alkalinity stress,the sequence of dry matter accumulation was S_3>S_0>S_2>S_1,the sequence of yield was S_0>S_3>S_2>S_1. |
