[Objective] This study aimed to verify the effects of new matrixes on tobacco seedlings on floating platform or field, and their effects on tobacco leaf yield and quality. [Method] The ratio of peat: carbonized rice hull: perlite: sand in the four new matrixes was 10∶40∶30∶20, 20∶40∶10∶30, 20∶40∶30∶10 and 20∶50∶10∶20, marked as T1, T2, T3 and T4, respectively. The ratio in control matrix was 35∶40∶25∶0. [Result]In formulas T1, T2, T3 and T4, the peat consumption was reduced by 70.1%,41.5%, 41.5%, and 41.5% respectively, which saved 12.5%, 23.1%, 8.2% and 12.8%of the cost. The new matrixes can effectively increase the seedling emergence rate of tobacco. The quality and duration of seedlings in float system with new matrixes showed no difference from those of control matrix. The values of output using the new matrixes were 323.10, 92.25, 39.30 and 2 250.60 Yuan/hm2higher than that of the control. Besides, the proportion of the first- and second-rate tobacco leaves was also improved. [Conclusion] These four new matrixes can be widely applied to raise seedling in a float system, and T4 is the best choice. 展开更多
