Abstract: In order to explore the effects of symbiosis between endophytic fungi and Hordeum bogdanii on nutrient contents and enzyme activities in rhizosphere and non-rhizosphere soils, Hordeum bogdanii with Epichloë endophytic fungi (E+) and without Epichloë endophytic fungi (E-) were planted in two fields in Wensu County, Xinjiang in this experiment. The contents of total phosphorus, available phosphorus, total potassium, available potassium, total nitrogen and organic carbon in rhizosphere and non-rhizosphere soils and the activities of soil urease, invertase, catalase and alkaline phosphatase were determined. The results showed that the contents of available phosphorus, total potassium, available potassium and organic carbon, and the activities of urease, sucrase, catalase and alkaline phosphatase in E+ and E- rhizosphere soils were significantly higher than those in non-rhizosphere soils. The correlation analysis of soil nutrients and enzyme activities showed that the activities of urease, sucrase and alkaline phosphatase in rhizosphere soil were significantly positively correlated with soil total phosphorus and organic carbon content. In non-rhizosphere soil, soil urease, invertase and alkaline phosphatase activities were significantly positively correlated with organic carbon. In addition, soil nutrient and enzyme activity redundancy analysis showed that organic carbon was the most important factor affecting rhizosphere soil enzyme activity. The above results showed that the symbiosis of endophytic fungi and H. bogdanii could improve the rhizosphere soil nutrient contents and enhance the rhizosphere soil enzyme activities, thereby improving soil quality and providing new ideas and scientific basis for soil improvement.

Key words: Endophytic fungi, Hordeum bogdanii, Rhizosphere and non-rhizosphere soils, Soil nutrients, Soil enzyme activity

摘要: 为了探究内生真菌与布顿大麦(Hordeum bogdanii)共生对根际和非根际土壤养分含量和酶活性的影响。本试验以新疆温宿县携带Epichloë内生真菌(E+)与不携带内生真菌(E-)的布顿大麦为材料,种植在2块大田中,测定其根际和非根际土壤全磷、效磷、全钾、速效钾、全氮、和有机碳等养分含量和土壤脲酶、蔗糖酶、过氧化氢酶和碱性磷酸酶活性。结果表明:E+、E-根际土壤速效磷、全钾、速效钾和有机碳等养分含量和土壤脲酶、蔗糖酶、过氧化氢酶和碱性磷酸酶性均显著高于非根际土壤。在低盐条件下,E+根际土壤速效磷含量和土壤过氧化氢酶、碱性磷酸酶和蔗糖酶活性均显著高于E-;在高盐条件下,E+根际土壤全磷、速效磷和速效钾养分含量和脲酶活性显著高于E-。土壤养分和酶活性相关性分析表明,根际土壤脲酶、蔗糖酶和碱性磷酸酶活性与土壤全磷和有机碳含量极显著正相关;非根际土壤中,土壤脲酶、蔗糖酶和碱性磷酸酶活性与有机碳呈显著正相关。此外,土壤养分和酶活性冗余分析表明,有机碳是影响根际土壤酶活性最主要的因素。以上结果表明,内生真菌与布顿大麦共生可以提高根际土壤养分含量和增强根际土壤酶活性,从而改善土壤质量,为土壤改良提供新思路和科学依据。
