摘　　要：为筛选合适盐碱地水稻生产的抗盐碱剂,以早稻品种陵两优942和晚稻品种Y两优911为材料,采用盆栽土培法研究了微纳米硅、矿源黄腐酸钾、盐碱消和松土精+矿源黄腐酸钾等4种抗盐碱剂对盐碱胁迫条件下水稻生长发育的影响。结果表明:水稻生长发育和产量会受到盐碱胁迫的影响,主要表现为植株分蘖能力下降、株高变矮、叶面积指数降低、干物质积累量减少等,施用抗盐碱剂可以缓解盐碱胁迫对水稻植株的这些影响,4种抗盐碱剂以微纳米硅的效果最佳,其次为松土精+矿源黄腐酸钾,再次是盐碱消,单施矿源黄腐酸钾的抗盐碱效果最差。To screen out salt-alkali resistant agents suitable for rice growth in salt-alkali soil,an early rice variety Lingliangyou 942 and a late rice variety Y Liangyou 911 were used as materials to investigate the effects of four salt-alkali resistant agents,silica nanoparticles(SiNPs),mineral potassium fulvate,Yanjianxiao,and Soilfix IR+mineral potassium fulvate,on rice growth and development under saltalkali stress conditions through pot experiments.The results showed that the growth and development of rice were affected by salt-alkali stress,resulting in decreasd tillering ability,lower plant height,smaller leaf area index and less dry matter accumulation.The application of salt-alkali resistant agents could alleviate saline-alkali stress to rice plants.SiNPs produced the best effect among the four salt-alkali resistant agents,followed by Soilfix IR+mineral potassium fulvate,and then Yanjianxiao;the single application of mineral potassium fulvate was undesirable.
