Effects of Vermicompost Substrate on Capsicum Seedlings

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.
