摘　　要：[目的]研究麝香草酚调控盐土中水稻耐盐作用。[方法]选取江苏省东台市盐度较高的水稻田(盐度4‰)为研究对象,在扬花期结合叶面喷施自主研发的天然生物刺激素制剂5%麝香草酚,评估麝香草酚在田间调控水稻耐盐的作用效果。[结果]喷施麝香草酚可显著提升盐土环境中水稻剑叶的生理状态,包括提高叶绿素、脯氨酸、还原性糖含量;喷施麝香草酚可提高盐土环境中水稻籽粒的饱满度、穗粒数、千粒重;喷施麝香草酚可提高盐土环境中稻米的黏稠度和醇溶蛋白含量,降低直链淀粉含量。[结论]田间喷施麝香草酚可有效提高水稻耐盐性、维持产量性状和稻米品质,为新型耐盐调控剂的研发和相应的田间应用技术开发提供科学依据。[Objective]To study the thymol regulate rice salt tolerance in saline soil.[Method]Selecting rice filed with high salinity(salinity 0.4‰)in Dongtai City,Jiangsu Province as the research object,self-developed natural bio-stimulator(5%thymol)at flowering period was sprayed,in order to evaluate the effect of thymol on the regulation of rice salt tolerance in filed.[Result]Spraying thymol was able to enhance the physiological status of flag leaves in saline soil,such as the increase in chlorophyll content,proline content and reducing sugar content.Spraying thymol increased the grain plumpness,kernel number per spike and thousand kernel weight in saline soil.Spraying thymol enhanced rice viscosity and prolamin content,and decreased rice amylose content in saline soil.[Conclusion]Spraying thymol effectively stimulated rice tolerance against salinity in field by maintaining productivity and rice quality in saline soil.This may provide scientific basis for the development of novel regulators conferring salt tolerance and its applying technology in field.
