ABSTRACT: As an important cash crop in China, Jerusalem artichoke is widely used in ecological protection, vegetable development, industrial and animal husbandry production and other directions, and has important production value. However, under the background of global warming, soil salinization has become increasingly serious, which has become one of the important factors endangering crop production. The adverse stress caused by salt in soil to plants includes osmotic stress and salt toxicity stress, which causes physiological drought and water extravasation in roots, and then suppresses the normal plants’ vegetation growth and reproduction. Silicon is the second most abundant oxygen element in the crust of the earth, which attracts much attention because it improves crop resistance to multiple stress environments. Therefore, based on the occurrence of drought salt stress in Jerusalem artichoke planting, this paper deeply explores the physiological response of plants to drought salt, and comprehensively analyzes the comprehensive regulation effect of exogenous silicon on drought stress and salt stress. This paper reviews the research on silicon’s regulation of plant drought and salt tolerance at home and abroad, analyzes the effects of silicon on the growth and development, photosynthesis and respiration of plants under drought and salt stress, with the aim of providing theoretical basis for related theoretical research and the application of silicon fertilizer in agricultural production.
