摘　　要：采用水培方法,研究发酵油菜籽油粕原液稀释成4种浓度的油粕营养液对蕹菜生长发育的影响。试验结果表明,10%油菜籽油粕原液除地下部鲜质量、干质量两项指标稍低外,蕹菜的地上部鲜质量和干质量、最大枝长、最大叶面积、总叶绿素含量均为最大,且可食部分产量最高。由此可见,10%油粕营养液浓度是一种比较适宜有机水培蕹菜的菜籽油粕原液稀释浓度。Four kinds of nutrient solution of different concentration which are diluted from ferment immersion of rape oil meal were selected to study on the effect of growth of lpomoea aquatica Forsk. The results showed that the fresh-weight and dry-weight of above-ground part of the plant in 10% treatment were the largest in all treatments. The maximum branch length, maximum leaf area, and total chlorophyll content were also the largest. 10% diluted ferment immersion of rape oil meal is the suitable nutritious solution for organic hydroponics of lpomoea aquatiea Forsk.
