Study on Tabacco Moist Tray Seedling under Different Nutrient Solution Concentration and the Ratio of the Substrate

[Objective]This paper in order to investigate the effect of different substrate ratio and different concentration of nutrient solution on moist tray seedling. [Method]The effect of different matrix and nutrient solution concentration on the tobacco seedling emergence rate,plant height,ect. [Result]Tobacco seedlings grow strong which have developed root system in the substrate adding 30% raw soil and nutrient solution produced in Longyan,Fujian. [Conclusion]The suitable moist tray seedling substrate are 100% substrate and the substrate adding 30%raw soil.
