摘要
本试验中将制成的改性秸秆保水剂应用到盐碱地冬小麦,探究改性秸秆保水剂对盐碱地冬小麦生长发育的影响.在相同的盐碱条件下施用不同剂量的改性秸秆保水剂后,分别测定苗期TaSOS1 基因表达量,苗期、开花期、灌浆期地上部氮磷钾含量,以及成熟期产量.结果表明,T2 处理的小麦不同时期地上部氮磷钾含量均高于或显著高于其他处理;小麦苗期,T2 处理的TaSOS1 基因表达量显著低于其他处理;收获期T2 处理的产量最高.施用改性秸秆保水剂有利于盐碱地小麦的生长发育,并对改良盐碱地具有一定作用.
Abstract
In this study,the modified straw water retaining agent made was applied to winter wheat in saline alkali soil to explore the impact of the modified straw water retaining agent on the growth and development of winter wheat in saline alkali soil,providing a theoretical basis and practical basis for the widespread application of the modified straw water retaining agent.After applying different doses of modified straw water retaining agents under the same saline alkali conditions,the nitrogen,phos-phorus,and potassium content in the aboveground parts of wheat during the seedling stage,anthesis stage,and filling stage,as well as the expression of TaSOS1 gene in seedling stage and yield were measured.The results showed that the contents of nitrogen,phosphorus and potassium in the aboveground parts of wheat in T2 were the highest at different stages,which were higher than or sig-nificantly higher than those in other treatments.At the seedling stage of wheat,the expression of TaSOS1 gene in T2 was significantly lower than that in other treatments.During the harvest period,the yield of T2 was the highest.The results showed that the application of modified straw water retai-ning agent was beneficial to the growth and development of wheat in saline-alkali land,and also had a certain effect on the improvement of saline alkali land.
