摘　　要：将生物炭用于胡椒园土壤,探讨生物炭对胡椒园土壤培肥的作用,为生物炭培肥胡椒园土壤提供依据。试验设计C1和C2两种,两种生物炭施用量均为炭土比10%、20%、30%,空白土壤为对照(CK),测试土壤有机质、水解性氮、有效磷、速效钾元素含量。研究结果表明:添加生物炭C1和C2都能显著提高胡椒园土壤有机质和速效钾含量,炭土比为30%的生物炭C2施用量对土壤有机质和速效钾含量的影响最大;生物炭C1和C2的添加对土壤水解性氮和有效磷含量的影响不明显。Use biochar to the soil of pepper gardens, the objective was to investigate the impact of biochar application on the soil of pepper gardens. And provide evidence for use biochar to improve soil fertility of pepper gardens. Application rate of Biochar C1 and C2 were the Biochar/soil of 10%, 20%, 30%. The soil of No biochar was CK, and determine contents of nutritive elements （N, P, K） .The results show that, the biochar C1 and C2 could significantly increase the soil organic matter and available potassium. The most influence on soil organic matter and available potassium is 30% biochar C2, the biochar C1 and C2 have no obvious effect on soil hydrolysable nitrogen and available phosphorus.
