In order to clarify the influence of different seedling substrates on the quality of rice seedlings,a randomized block design was adopted for experimental research.The results showed that compared with the conventional nutrient soil for raising seedlings,the comprehensive quality of rice seedlings under the medium-grain seedling substrate was stronger,especially the root length,dry weight of 100 plants,fullness,and rooting root number of the seedlings,which were different from those of conventional nutrient soil.All have reached a significant level,and the advantages of seedling raising can replace conventional nutrient soil seedlings.
