| 摘 要： | 以辣椒品种二荆条为试材，研究了外源化感物质香草酸对辣椒幼苗根际土壤酶活性及土壤养分含量的影响。结果表明
：4种土壤酶活性均随着香草酸浓度增加而呈增大的趋势，其中影响最大的是多酚氧化酶，在香草酸浓度为1×10-7 mol·L-1
时，其活性较对照显著增加了13.3 %；土壤有机质、有效磷及速效钾含量均随着香草酸浓度的增加而呈降低的趋势，而土壤
硝态氮含量却呈增加的趋势；4种土壤酶活性均与土壤有机质含量、有效磷含量及速效钾含量呈极显著负相关，而与土壤硝态
氮含量呈显著或极显著正相关。

| Abstract: | Effect of exogenous allelochemical vanillic acid on soil enzyme activity and soil nutrient for
pepper seedling was studied in this article.The results showed that 4 kinds of soil enzyme activities were
increased along with the increase of vanillic acid concentration.Furthermore,polyphenol oxidase activity
increased by 13.3 %，compared to the control when vanillic acid concentration got 1×10-7 mol·L-1.The
contents of soil organic matter,available P and available K tended to decrease with the increase of vanillic
acid concentration.While the soil NO-3-N content tended to increase.Relations between the 4 soil enzyme
activities and soil organic matter content,available P and available K were significantly negative.But their
relation with soil NO-3-N contents was significantly positive or very significantly positive. |
