盐碱胁迫抑制种子的正常萌发,妨碍作物在盐碱地的生长。内蒙古赤峰地区盐碱地较多,如能充分利用这些盐碱地,选择适合栽培的作物品种,就能更好的解决牧区粮饲问题。高粱有一定的耐盐碱性,筛选一些耐盐耐碱的优良品种,保证播种后发芽率、出苗率,解决生长不整齐、缺苗断垄等一系列问题,是提高产量的前提。为此本试验以3种不同基因型高粱种子为材料对其进行混合盐碱胁迫,通过发芽试验系统的研究了解不同 Saline-alkali stress inhibits the normal seed germination and hinders crop growth in saline-alkali soil. There are more saline-alkali lands in Chifeng area of ​​Inner Mongolia. If we can make full use of these saline-alkali lands and select suitable crop varieties for cultivation, we can better solve the problem of grazing in pastoral areas. Sorghum has certain salt and alkali resistance, screening some of the fine varieties of salt and alkali tolerance, to ensure that after sowing germination rate, emergence rate, to solve the growth of irregular, lack of seedlings broken ridge and a series of issues is to improve the yield of the premise. To this end, three different genotype sorghum seeds were used as materials to mix salt-alkali stress, and the germination test system was used to understand the difference
