Abstract

In order to reuse vermicompost and elevate the quality of vegetable seedlings,the effects of nitrogen fertilizer added to vermicompost-formulated substrate on seedling growth of solanaceous vegetables including eggplant,tomato and capsicum were investigated.Results showed that the planting percent,leaf expandedness,plant height,stem diameter,fresh and dry weight,leaf number,leaf chlorophyll content and strong seedling index of the seedlings raised in vermicompost-formulated substrate were superior to those raised in a commercial substrate(CK).Addition of 0.5 kg ·m(-3)(urea) to vermicompost-formulated substrate was favorable for the aerial growth of eggplant seedlings and biomass accumulation of the seedlings of tomato and capsicum.The optimum rate of urea added to vermicompost-formulated substrate for aerial growth of eggplant seedlings was 1.0 kg·m(-3) while that for biomass accumulation of the seedlings of tomato and capsicum was 2.0 kg ·m(-3).The planting percentage of solanaceous vegetables was higher and more stable when 0.5-1.0 kg·m(-3) urea was added to vermicompost-formulated substrate,and the optimum rate of urea added to vermicompost-formulated substrate for strong seedling development was 1.0 kg·m(-3) in eggplant and capsicum and 0.5 kg·m(-3) in tomato.These data indicatedthat vermicompost-formulated substrate could be used as a better substrate in raising the seedlings of solanaceous vegetables and the optimum addition of urea to the substrate was 0.5-1.0 kg·m(-3).
