Tentative research of Na compound fertilizer at seedling stage on enhancing drought resistance of Haloxylon ammodendron

Abstract

Abstract: We mainly investigated morphological indexes, biomass, Na⁺ and K⁺ contents using potted Haloxylon ammodendro seedlings transplanted into a sandlot at the end of the three months growing season. There is a preliminary discussion on the effects of Na compound fertilizer application on induction of strong drought resistance in H. ammodendro seedlings. Comparing Na compound fertilizer with the control and with Diammonium phosphate, plant height increased by 42% and 18%,the branching number by 22% and 14%, the main stem diameter by 48% and 23%, the main root diameter by 37% and 24%,the crown diameter by 57% and 28%,the root/shoot ratio by 18% and 18%, the total fresh biomass by 130% and 74%,the total dry biomass by 154% and 74%, and the Na⁺ contents of shoots by 60% and 49%,but the K⁺ contents of roots decreased by 28% and 31% respectively (P<0.05). It is suggested that Na compound fertilizer application not only promotes the growth, but also improves drought-tolerance of H. ammodendro seedlings.
