摘要

天缘是限制作物生产力的最残酷的环境因素之一。因此,迫切需要开发环境友好型技术来提高盐碱地小麦的生长和生产力。在我们为期2年的田间试验中,我们评估了两种有益植物生长促进根细菌(PGPR;巴西氮螺旋菌(Azospirillum brasilense)和环状芽孢杆菌(Bacillus circulans)与硅酸钾(k2sio3)叶面施用;PS)在盐渍土壤下提高Misr 1、Gemmeza 12和Sakha 95三个小麦品种的生长和产量(EC=7.71)。结果支持了我们的假设,即与单独施用PGPR或PS和未处理(对照)植株相比,PGPR+PS配施显著(P <0.05)提高了植株的生长和产量、养分(N、Na +和K +)吸收、光合色素、脯氨酸含量和总可溶性糖含量。此外,联合施用显著(P <0.05)提高了过氧化物酶和过氧化氢酶活性,清除了活性氧的损伤作用。结果表明,复合施用可以激活土壤关键酶,主要是脱氢酶和脲酶,提高土壤微生物活性。综上所述,在盐胁迫下,PGPR与PS联合施用作为一种简单、低成本的生物方法,在改善土壤性质、促进植物生长、提高小麦元素含量方面显示出积极的效果。

Potassium Silicate and Plant Growth‐promoting Rhizobacteria Synergistically Improve Growth Dynamics and Productivity of Wheat in Salt-affected Soils
alinity is one of the most brutal environmental factors limiting the productivity of crop plants. Thus, there is an urgent need for environmentally friendly techniques to enhance growth and productivity of wheat ( Triticum aestivum L.) growing in saltine soils. In our 2-year field experiments, we evaluated the effect of two beneficial plant growth-promoting rhizobacteria (PGPR; Azospirillum brasilense and Bacillus circulans ) and the foliar application of potassium silicate (K 2 SiO 3 ; PS) to improve growth and yield of three cultivars of wheat, namely Misr 1, Gemmeza 12 and Sakha 95, under salt-affected soils (EC=7.71). The results supported our hypothesis that the combined application of PGPR+PS significantly ( P <0.05) improved growth and yield, nutrients (N, Na + and K + ) uptake, photosynthetic pigments, proline content, and total soluble sugars content compared to the individual application of PGPR or PS and the untreated (control) plants. In addition, the combined application significantly ( P <0.05) increased peroxidase and catalase activities, scavenging the damage effects of the reactive oxygen species. Our data revealed that the combined application could activate the soil key enzymes, mainly dehydrogenase and urease, and boost soil microbial activity. Overall, the combination of PGPR and PS applications, as a simple and low-cost biological method, has shown a positive effect in terms of improving soil properties, enhancing plant growth, and increasing element contents of wheat under salinity stress.
