摘要
以10个谷子品种为试验材料,采用对比设计,研究了盐碱胁迫对谷子农艺性状及产量的影响。结果表明:盐碱胁迫对谷子产量及农艺性状的影响程度不同,品种之间差异较大;保苗率对产量影响最大,其次为穗粒重,穗重和穗数主要通过穗粒重及保苗率对产量产生影响。
The effects of saline-alkali stress on the agronomic traits and yield of ten millet cultivars were studied by the method of contrastive design.The results showed that the saline-alkali stress had different impacts on the yield and agronomic traits of the ten cultivars.The effect of survival rate of seedlings on the yield was greater than grain weight per spike.The spike weight and spike number influenced the yield through the grain weight per spike and survival rate of seedlings.
