摘要:
 为探讨盐碱地耐盐植物对根际土壤理化性质及微生物功能多样性的影响，以黑果枸杞、沙棘、银水牛果和柽柳4种耐盐植物为材料，分别添加不同浓度的NaCl和NaHCO3溶液模拟不同盐碱胁迫条件，设置中度盐胁迫（T1，500 mmol·L-1 NaCl）、重度盐胁迫（T2，750 mmol·L-1 NaCl）、中度碱胁迫（T3，500 mmol·L-1 NaHCO3）和重度碱胁迫（T4，750 mmol·L-1 NaHCO3）处理，以浇灌自来水为对照（CK，0 mmol·L-1），分别测定不同处理根际土壤的理化性质，并采用Biolog-ECO微平板技术测定根际微生物功能多样性。结果表明，4种耐盐植物的土壤有机质随盐碱胁迫的增加呈降低趋势，且种植1 a后土壤有机质呈降低趋势；不同盐碱胁迫下土壤全N、全P和全K含量也呈降低趋势，但方差分析显示差异不显著，种植1 a后的土壤全N、全P和全K含量升高。柽柳和黑果枸杞根际土壤的平均每孔颜色变化率（average well color development，AWCD）比沙棘和银水牛果高，但丰富度、Shannon均匀度和Simpson指数在不同处理间没有明显差异。相关性分析表明，土壤全N和有机质与AWCD呈极显著正相关（P<0.01），土壤全N与微生物Shannon指数呈显著正相关（P<0.05），土壤全P与丰富度指数呈显著正相关（P<0.05）。主成分分析表明，根际土壤微生物群落对碳源利用能力由大到小为胺类、多聚物类、糖类，其次是氨基酸类、羧酸类。因此，耐盐植物有利于提高根际土壤养分，提高根际土壤微生物代谢活性和根际土壤微生物群落功能多样性，是盐碱地区生态恢复的一项有效措施。
Abstract:
 In order to explore the effects of planting salt-tolerant plants on rhizosphere soil physicochemical properties and microbial functional diversity in Ningxia saline-alkali areas,four halophyte plants,such as Lycium ruthenicum,Hippophae rhamnoides,Shepherdia argentea and Tamarix chinensis were selected as the research materials.Five different saline-alkaline stresses were simulated by adding different concentrations of NaCl and NaHCO3 solutions,i.e.,T1 (medium salt stress,500 mmol·L-1 NaCl),T2 (severe salt stress,750 mmol·L-1 NaCl),T3 (medium alkaline stress,500 mmol·L-1 NaHCO3),T4 (severe alkaline stress,750 mmol·L-1 NaHCO3) and control (tap water,0 mmol·L-1 NaCl or NaHCO3),physicochemical properties of their rhizosphere soil were determined in October 2015 and October 2016,and rhizosphere microorganism functional diversity was determined using the Biolog-ECO microplate technology in October 2016.The results were as follows.Soil organic matter content of four salt-tolerant plants decreased with the increase of stress intensity,and it also decreased after planted for one year.Soil total N,total P and total K contents also decreased indistinctly under different saline-alkaline stresses.Soil total N,total P and total K contents increased after planted for one year.The average well color development (AWCD) values of rhizosphere soil in T.chinensis and L.ruthenicum were higher than H.rhamnoides and S.argentea,but the richness,Shannon evenness and Simpson index in different saline-alkali treatments were non-significant differences among them.Correlation analysis showed the soil total N and organic matter were extremely significantly and positively correlated with AWCD (P<0.01),and significantly and positively correlated with microbial Shannon index (P<0.05).Soil total P was significantly and positively correlated with richness index (P<0.05).Principal component analysis showed that the carbon source utilization ability of rhizosphere soil microbial communities was:amines,polymers,sugars,and followed by amino acids and carboxylic acids.Therefore,salt-tolerant plants are conducive to enhance rhizosphere soil nutrients,improve microbial metabolic activity and soil microbial community functional diversity in rhizosphere soil.It is an effective measure for ecological restoration in saline-alkali areas.
