摘要/Abstract

摘要： 伴随连作年限的增加,日光温室黄瓜连作土壤中酚酸类物质(对羟基苯甲酸、阿魏酸、苯甲酸)明显积累,连作5～9年的土壤酚酸类物质含量显著高于连作1～3年的土壤.伴随外源酚酸类物质处理浓度的增加,黄瓜根区土壤中细菌、放线菌和微生物总量以及N生理群均呈先升后降趋势,在80 μg·g^-1处理浓度下细菌、放线菌数量最多,处理浓度在120μg·g^-1以下土壤真菌数量(包括尖孢镰刀菌、疫霉)急剧增长;多酚氧化酶、过氧化氢酶、蔗糖酶、脲酶和蛋白酶活性也同样呈先升后降趋势,但其峰值对应的浓度不同.

Abstract: The study showed that in solar greenhouse continuously cropped cucumber soil,phenolic acids p-hydroxybenzoic acid,ferulic acid and benzoic acid had an obvious accumulation with increasing cropping year,and their contents were significantly higher after continuously cropped for 5～9 years than for 1～3 years.With the increasing concentration of treated exogenous phenolic acids,the amounts of bacteria,actinomycetes,total microbes,ammonibacteria,and nitrifying bacteria in cucumber root area increased first,but decreased then.Soil bacteria and actinomycetes had the largest amount at the concentration of 80 μg phenolic acids.g^-1 soil,while soil fungi(including Fusarium and Phytophthora) increased rapidly when the concentration of phenolic acids was lower than 120 μg·g^-1 soil.With increasing phenolic acids concentration,soil enzyme activities also increased first but decreased then,with the peak values differed in different treatments.
