摘　　要：研究了辣椒叶水浸液对辣椒幼苗根际土壤酶活性及土壤养分的影响。研究结果表明,4种土壤酶活性均有随着辣椒水浸液浓度增加而增大的趋势,其中影响最大的是纤维素酶,水浸液在10g·L-1时,其活性较对照显著增加了23.1%;辣椒叶水浸液均随着浓度的增加降低了土壤pH值,土壤有机质、有效磷及速效钾含量;4种土壤酶活性均与土壤pH值,土壤有机质、有效磷及速效钾含量呈负相关。Effect of pepper leaf aqueous extract on soil enzyme activity and soil nutrient of pepper seedling was studied. The results showed that four soil enzyme activities increased with increase in aqueous extract concentration. Furthermore, cellulose activity increased by 23.1% compared to the control when aqueous extract concentration got 10 g·L^-1. Pepper leaf aqueous extract reduced soil pH, soil organic matter content, available P and available K with increased concentration. Relationship between four soil enzyme activities and soil pH, soil organic matter content, available P and available K was negative.
