以2个高粱品种吉杂123(JZ123)和龙杂11(LZ11)为材料,设置5个不同盐浓度(0、0.3%、0.4%、0.5%、0.6%)处理,探讨了盐胁迫对不同高粱品种农艺性状和产量形状的影响。试验结果表明:不同浓度盐胁迫下,高粱的农艺性状和产量均受到不同程度抑制,且盐浓度越高,抑制作用越明显,与对照差异均达到极显著(P<0.01),2个品种的农艺性状和产量随盐浓度的升高均表现出以下变化:相对成苗率下降,出苗时间延迟,株高变矮,茎粗变细,千粒重、穗粒重和产量下降,尤其穗粒重和产量的下降幅度最为明显。综合2个高粱品种的性状表现,LZ11的耐盐能力较强于JZ123,更适于盐碱地栽培。
Five different salt concentrations (0,0.3%, 0.4%, 0.5%, 0.6%) were set up with two sorghum varieties JZ123 and LZ11 as materials, Effect of Sorghum Varieties Agronomic Traits and Yield and Shape. The results showed that under different salt stress, the sorghum agronomic traits and yield were inhibited to some extent, and the higher the salt concentration, the more obvious the inhibitory effect was, and the difference was significant (P <0.01) Agronomic traits and yield all showed the following changes with the increase of salt concentration: the relative seedling rate decreased, the emergence time was delayed, the plant height became shorter, the stem diameter became thinner, the grain weight per plant, the grain weight per ear and the grain yield decreased, especially the grain weight per plant The most obvious drop in output. Combining the characters of two sorghum cultivars, LZ11 had stronger salt tolerance than JZ123 and was more suitable for saline-alkali soil cultivation.
