Effect of super absorbent polymer on the growth and root morphology of Haloxylon ammodendron seedlings

Abstract

Abstract: The effect of different concentrations of super absorbent polymer (SAP) on soil moisture, growth and root morphology of 1-year Haloxylon ammodendron was studied. 0.2% SAP significantly increased soil moisture at a depth of 30-40 cm when soil moisture was relatively low. 0.05% SAP promoted the growth of assimilating shoots of H. ammodendron, notably from April to June when soil moisture was relatively high, but 0.2% SAP had the most obvious effect from July to September when soil moisture was relatively low. The height, crown width, new branch length, and basal diameter of H. ammodendron were significantly improved when the SAP concentration was 0.2%. Both 0.05% and 0.2% SAP concentrations significantly improved root surface area by 64.65% and 125.62% respectively and total root length by 81.68% and 130.92%. It was concluded that the optimal SAP concentration for H. ammodendron growth was 0.05% from April to June, and 0.2% from July to September.
