摘　　要：我国盐碱地面积广阔,开发利用盐碱地可以提高粮食产量和改善生态环境,具有直接的生态效益和经济效益。目前,盐碱地水稻可种植面积有限,而且单产非常低。因此,培育耐盐碱水稻品种并提高耐盐碱水稻单产,对于粮食增产和盐碱地利用具有重要意义。本试验在耐盐碱水稻灌浆期喷施芸苔素甾醇与磷酸二氢钾和有机硅复配,研究植物生长调节剂对耐盐碱水稻产量的影响。结果表明,0.01%芸苔素甾醇和磷酸二氢钾复配能够提高耐盐碱水稻的穗粒数、实粒数,并显著提高千粒重,其中千粒重增长率最高可达12.32%,提高了耐盐碱水稻的饱满度。该研究结果能够为耐盐碱水稻种植提供理论依据。There is a vast area of saline-alkali land in China.The development and utilization of saline-alkali land can increase grain yield and improve ecological environment,which has direct ecological and economic benefits.At present,the planting areas of saline-alkali land rice are limited and the yield per unit area is very low.Therefore,it is of great significance to cultivate saline-alkali tolerant rice,improve the yield per unit area of saline-alkali land rice and increase grain yield and saline-alkali land utilization.In this study,the mixture of brasszinosteroid and potassium dihydrogen phosphate,organosilicone were sprayed during the filling period of saline-alkali tolerant rice to investigate the effect of plant growth regulator on the yield of saline-alkali tolerant rice.The results showed that the combination of 0.01%brasszinosteroid and potassium dihydrogen phosphate could improve the grain number per panicle,total filled grains and 1000-grain weight of saline-tolerant rice.The maximum value of the increase rate of 1000-grain weight could reach up to 12.32%,which improved the plumpness of saline-tolerant rice.The results of this study could provide theoretical basis for saline-tolerant rice cultivation.
