摘　　要：自毒物质引起的苹果连作障碍是苹果生产中面临的一个重要问题。为了了解黄土高原苹果优势主产区连作与非连作土壤中酚酸物质类物质组成和含量差异,本研究文采用实地调研取样和高效液相色谱法对山西运城临猗、平陆,陕西渭南白水、延安洛川、铜川印台等黄土高原区苹果园连作与非连作土壤中酚酸物质的组成和含量进行了分析比较。结果表明:连作障碍发生的苹果园土壤中酚酸类物质的组成和含量在不同地区、不同土层厚度间存在显著差异,山西地区非连作果园中绿原酸的含量40～60cm土层行间最高,分别是行间20～40、0～20cm土层绿原酸含量的1.5倍和21倍,而根皮苷酸则在0～20和40～60cm土层行内均未被检测到;陕西地区非连作园土壤中绿原酸随土层厚度未见明显变化,而根皮苷酸只在40～60cm土层行内检测到。连作土壤中的主要酚酸类物质是绿原酸、根皮苷和苯甲酸,陕西地区苹果园行内连作土壤中三者之和在各土层均超过总酸量的66%。Replant disease caused by autotoxic substances has become an important problem in apple production.Loess Plateau is a main apple production region of China.The composition and contents of phenolic acids in the soil of replanted and no-replanted apple orchards in Loess Plateau,including Linyi,Pinglu,Baishui,Luochuan and Yintai,were investigated and analyzed by HPLC.The results showed that the composition and contents of phenolic acids in the apple orchard soil of different regions and depth were significantly different.The contents of phenolic acids decreased slowly over time.Content of chlorogenic acid in 40-60 cm soil layer was1.5 times that in 20-40 cm soil layer,and 21 times that in 0-20 cm soil layer in Shanxi region.Phloridzin was not detected in 0-20 cm and 40-60 cm soil layers in Shanxi.There was no significant change in chlorogenic acid content in soil layers,and phloridzin was only detected in 40-60 cm soil layer in Shaanxi.Pyrogallic acid,chlorogenic acid and phlorizin were main phenolic acids in replanted soils.The content of pyrogallic acid,chlorogenic acid and phlorizin constitutes more than 66% of total content of phenolic acids in Shaanxi.
