Taking the organic active substrate produced by Huaiyin Vegetable Research Institute as control, we studied the effects of ten self-made wormcast substrates on the pepper seedlings' height, stem diameter, expansion degree, chlorophyll content, leaf number, over-ground part's fresh weight and dry weight, and underground part's fresh weight and dry weight at the early, middle and later seedling stages respectively. The results showed that the treatment T0 (wormcast+vermiculite+N2+P+K) had significantly better effects on the quality of pepper seedlings, and the seedlings grew vigorously and possessed excellent quality, thus the substrate formula of T0 treatment was ideal for cultivating pepper plug-seedlings.% 以淮阴市蔬菜所研制的有机活性基质为对照(CK)，设置了10种自制蚯蚓粪基质配方处理，研究了不同配方蚯蚓粪基质在辣椒育苗前期、中期和后期对幼苗株高、茎粗、开展度、叶绿素含量、叶片数、地上部鲜质量、地下部鲜质量、地上部干质量和地下部干质量等性状的影响。研究结果表明，蚓粪+蛭石+N2+P+K基质配方处理的效果最佳，幼苗质量良好、生长健壮，且与其他基质配方相比，差异达显著水平，是较理想的辣椒育苗基质。
