摘　　要：通过向蚓粪中添加不同量蛭石制成复合基质,研究不同基质处理对辣椒幼苗各生长期的影响。结果表明:不同处理随育苗期延长差异逐渐显现。根据干物质平均积累量和壮苗指数筛选出蚓粪蛭石以8∶1(V∶V)混合的基质对辣椒幼苗的生长促进效果最好;辣椒幼苗在复合基质(除2∶1外)上的生长较蚓粪基质和对照基质(CK)好。研究结果为污泥资源化农用及解决育苗基质缺肥问题提供了科学依据。Effect of vermicompost substrate formulated with different vermiculite dosages on seedling development in capsicum were systematically investigated, with an aim to understand the role of vermicompost in raising strong seedling in greenhouse vegetable production. The results showed that there was no significant effect on the initial stage of growth, but the effect gradually varied as the seedling period extended. According to the average dry matter accumulation and health seedling index, the optimal ratio of vermicompost to vermiculite was 8∶1. Apart from 2∶1, the compound substrates was better than either the substrate made from simple vermicompost or CK. This experiment will provide sludge recycling and seedling substrates deficient in fertilizer with scientific basis.
