摘　　要：以蚯蚓粪为主要原料配合不同体积比的蛭石作为穴盘育苗基质与草炭对比,研究了复合基质对辣椒种子出苗率及幼苗生长发育的影响。结果表明:与草炭相比,蚯蚓粪容重较大、孔隙度和持水力较小,高P、K含量和低N含量;蚯蚓粪复合基质促进了辣椒幼苗生长发育,其作用效果与基质混合比例有很大关系,3∶1(V∶V)蚯蚓粪复合基质育苗效果最佳。To study the application effect of vermicompost as cultural substrate of pepper plug seedlings, the physical and chemical charactertics of vermicompost from cornstalk, the emergence rate and quality of seedling growing in mixes of vermicompost and vermiculite with different ratio were evaluated. The results showed that vermicompost had greater volume weight, smaller water retention, higher concentration phosphate and potassium and lower rate of nitrogen compared with peat; vermicompost compound suhstrates promoted growth and development of pepper plug seedlings, their application effect was closely related to ratio of vermicompost and vermiculite, the optimum ratio was 3V/1V.
