Effects of different cultivation substrates on seedling quality of wet-cultivated water dropwort

To cultivate vigorously growing water dropwort seedings with uniform performance，substrates and field soil were mixed in different proportions and the optimum substrate formulation for water dropwort growing was selected. Using wet-cultivated water dropwort（Oenanthe stolonifera D.C.）‘D07’as materials，the effects of different cultivation substrates on growth， root activity and functional components of root and leaf blades were studied. The results showed that，when the ratio of vegetable substrate to field soil was 1∶1， or the ratio of wormcast to field soil was 3∶2，the seedlings the plant growth was the highest and the best， the strong seedling index values were both 0.13， had high photosynthetic pigment content， and their roots developed well， the two substrates were good for seedling growth of wet-cultivated water dropwort.
