RESULTS: The results showed a 10-39% increase (compared to non-saline control) in agronomic, physiological, and nutritive attributes of wheat plants when augmented with PM and microbes. Microbes together with PM significantly enhanced seedling emergence (up to 38%), agronomic (up to 36%), and physiological (up to 33%) in saline soil as compared to their respective unamended control. Moreover, the co-use of microbes and PM also improved soil\'s physicochemical attributes and enhanced N (i.e., 21.7%-17.1%), P (i.e., 24.1-29.3%), and K (i.e., 28.7%-25.3%) availability to the plant (roots and shoots, respectively). Similarly, the co-use of amendments also lowered the Na+ contents in soil (i.e., up to 62%) as compared to unamended saline control. This is the first study reporting the effects of the co-addition of newly identified salt-tolerant bacterial strains and PM on seedling emergence, physiology, nutrient uptake, and growth of wheat in highly saline soil.
CONCLUSIONS: Our findings suggest that co-using a multi-trait bacterial culture and PM could be an appropriate option for sustainable crop production in salt-affected soil.
结果:结果表明,农艺性状增加了10-39%(与非盐水对照相比),生理,以及添加PM和微生物后小麦植株的营养属性。微生物与PM一起显着增强幼苗出苗(高达38%),农艺(高达36%),与各自未修正的对照相比,盐渍土壤中的生理含量(高达33%)。此外,微生物和PM的共同使用也改善了土壤的物理化学属性和增强的氮(即,21.7%-17.1%),P(即,24.1-29.3%),和K(即,28.7%-25.3%)对植物的可用性(根和芽,分别)。同样,共同使用改良剂也降低了土壤中的Na+含量(即高达62%),与未修正的盐水对照相比。这是第一项研究报告了新鉴定的耐盐细菌菌株和PM共同添加对幼苗出苗的影响,生理学,营养吸收,和小麦在高盐渍土壤中的生长。
结论:我们的研究结果表明,在受盐影响的土壤中,共同使用多性状细菌培养和PM可能是可持续作物生产的适当选择。
