无机基质配比及沼渣施肥水平对无土栽培苗用型大白菜生长的影响
Effect of Inorganic Substrate Ratio and Fertilization Levels of Biogas Residue on Growth of Seedling-edible Chinese Cabbage in Soilless Cultivation
摘要
Abstract
Using biogas residue whose contents of N, P and K nutrient is pre-adjusted as fertilizer in compound substrate comprising perlite and vermiculite, this experiment studies the effects of 2 substrate ratios and 3 fertilization levels of biogas residue on the growth, yield and quality of seedling-edible Chinese cabbage [Brassica campestris L. ssp. pekinensis (Lour) Olsson ) ' Jingyankuaicai' . The results showed that the effect of substrate ratio had significant influence on its growth, the fertilizer level of biogas residue took the second place. In the same fertilization level of biogas residue, the morphological index, VC and soluble sugar contents, fresh and dry weight, and yield of A2 (the substrate ratio of 1 perlite and 2 vermiculite ) are better than Al ( the substrate ratio of 2 perlite and 1 vermiculite ) basically. In the same substrate ratio cultivation, the plant height, leaf length, leaf width, leaf number, fresh and dry weight, yield and nitrate content were improved with the increasing of biogas residue content, but the difference between 36.6 g per plant fertilization of biogas residue and 44.0 g is not significant, except leaf width and nitrate content. Collectively, these results indicated that 'Jingyankuaicai' grew stronger with higher yield and better quality with the substrate ratio of 1 perlite and 2 vermiculite, and 36.6 g per plant fertilization of biogas residue.关键词
