Effects of Licorice Planting on Physical, Chemical Properties and Microbial Function Diversity of Saline Soil
摘要
Abstract
The study aims to investigate the effect of planting licorice on physical and chemical properties and microbial community functional diversity in saline soil. Bare land (no planting Glycyrrhiza inflate) was set as control, and conventional methods were adopted in the experiment. Soil microbial community functional diversity was studied using BilogECO plates. Results showed that compared with that of control, the contents of total nitrogen, alkalystic nitrogen and organic matter of saline soil with licorice planting were significantly increased by 38%, 48%and 33%, respectively (P<0.05), electrical conductivity of soil significantly decreased by 262% (P<0.05). The results indicated that the Average Well Color Development (AWCD) of licorice growing soil was higher than that of bare land (CK). Compared with that of bare land (CK), AWCD of licorice growing soil significantly increased by 28%after cultured for 72 h. The utilization ratio of soil microorganism to sugar carbon sources in the licorice plot significantly increased by 28% (P<0.05) and the soil microbial diversity was higher than that of bare land (CK) (P<0.05). Principal component analysis demonstrated that licorice changed the soil microbial community composition. Sugars and amino acids were the primary carbon sources to lead to the difference, followed by the hydroxyl acids and polymers category carbon sources. In a word, planting licorice could improve the activity and functional diversity of soil microbial community in saline soil. So licorice cultivation was a reasonable choice for ecological restoration in saline soil.关键词
