Abstract

Abstract:

This paper delineated the integrated technological work process (encompassing cultivar selection, soil amelioration and cultivation management) developed for drought-alkali wheat expansion on saline soils in Cangzhou. It reviewed the consecutive growth trajectory in which the cropped area rose from 5.9×10⁴hm² in 2020 to 1.2×10⁵ hm² in 2024, and the grain yield increased from 3.1×10³to 4.3×10³kg/hm². The inhibitory effects exerted by drought, high salinity-alkalinity and low temperature-low light stresses during the growing season on seed germination, tiller formation and grain filling were summarized. The latest mechanisms of exogenous abscisic acid (ABA), silicon formulations and cerium oxide nanoparticles in enhancing root Na⁺ exclusion, maintaining foliar K⁺ homeostasis and scavenging reactive oxygen species were analyzed. A full-cycle, targeted green-regulation technical system centered on a framework of ‘seed treatment for stress-resilient germination and tillering stem-strengthening chemical regulation at jointing; culm-strengthening chemical regulation at jointing to improve lodging resistance and stress resilience; flag-leaf-sustaining and grain-filling-promoting regulation during the grain-filling stage’ was proposed, offering a replicable technological route for yield enhancement and green, efficient production of drought-alkali wheat.

Key words: Cangzhou, drought-alkali wheat, saline-alkali lands, green regulation technology, biological agents, efficient planting, resistance to stress and increased production
